IN the chaos that surrounds our day-to-

day activity on the Internet we seldom

realize the dangers that hover around us

in inconspicuous orms. The great Isaac

Newton stated that there’s always an equal

and opposite orce acting against every

action perormed. Only in the case o you,

the common user, this negative orce is a lot

more than equal. There are threats coming

in rom every corner, be it rom the Internet

or outside.

This issue o CHIP Plus is a guide to what you

need to do to stay sae in this precarious

environment. We all know that anti-virus

utilities make some really tall claims o

being one better than the other, but how

can we trust them? We need to build a ew

deenses ourselves, rather than completely

rely on a single application to do this. The

misconception o users that installing

security tools is a waste o money, oten

costs them more dearly in the orm o dataloss. Thankully, developers are kind enough

to provide some security applications or

ree. This acts as a catalyst or users to

download them and make sure that they

have at least a single line o deense ready.

Besides the expected measures we take to

shield data rom being stolen or destroyed,

we also give you a ew quick tips on how

to end o attempts o physical thets

by robbers and burglars. Another look at

physical computer security covered hereincludes the shielding o USB drives against

inections. You will learn how easy it is or

you to lose all your data ater borrowing

that innocent looking pen drive to copy a

presentation. Trust me, it isn’t all that sae

out there.

Attackers use tricks such as attractive ads, oers or

ree stu, etc. to tempt you to click on a particular link

or object on the page. This click could be atal. Thus

we can broadly classiy these attacks based on the

targets that they have. So we call them:

ATTACKS ON OUR INTEGRITY: Our data is being

modifed or destroyed by unauthorized means.

ATTACKS ON OUR CONFIDENTIALITY: Our data

is being viewed by those who do not have the

permission to do so.

ATTACKS ON OUR AVAILABILITY: Not every rightul

user can access the data because it is being denied to

them by an attack/attacker.

WHAT KIND OF ATTACKS ARE WEVULNERABLE TO?

To get into our systems and access our data, attackers

resort to various means. Some o these trick us into

alling or them by using attractions like ree git

vouchers or ree downloads. Others simply creep

To begin with, we need to defne the kind

o environment that we are working in.

Networks that have a single administrator

are way saer than those that don't have any. This

is because well administered systems have rules

that allow and deny access o certain components

or computers over a network. In regular peer-to-

peer networks security lapses are quite common.

WHO ATTACKS US AND WHY?

To avoid threats, we frst need to know who we are

up against. These attackers are called 'hackers' or

'crackers', depending on whether they are meant

to dig into your personal inormation, modiy

it or even destroy it ully. Besides targeting just

your computer, these attackers can also launch

attacks on other computers by using your system

as an access point. By doing this, they can remain

discrete in their actions and end up jeopardizing

your integrity on the network.

into our systems without our knowledge. Attacks like

worms, viruses and Trojans are generally pre-coded

and stored at some point in a website or anywhere on

the Internet. These can be mailed to us, and to several

other targets at a time as an attachment, which, on

clicking, can penetrate our systems.

However, though these are the most common

attacks, we also have some others. All o these are

mentioned in the ollowing points:

WORMS, VIRUSES AND TROJANS: As mentioned

earlier, these programs are pieces o code that aect

some part o our operating system. Worms are known

or replication; viruses cause direct attacks on our

data by deleting, altering or adding data without our

permission. Trojans reside as harmless entities which

later cause problems by picking up our sensitive

inormation like logins and passwords.

DOS ATTACKS: One o the most common attacks

is the DoS (Denial o Service) attack. In this case,

certain or all components o your system are made

unavailable to you. For example, your PC will be

'pinged' over and over again so as to congest your

network tra c. This will deny you using your own

PC over the network. The most common targets

or attackers oten include blocking a certain web

portal or component rom being used. Besides being

annoying, this can also lead to some serious downtime

in your work. Even worse, attackers can ood the

victim's bandwidth with requests rom multiple

systems. This kind o attack is called DDoS (Distributed

Denial o Service). Certain Trojans can also be used to

execute this kind o attack.

BROWSER HACKS: Certain websites and applications

have scripts like JavaScript and ActiveX controls. These

can be used to pick up inormation like login details,

browsing history, etc. and display it to unauthorized

personnel. However, the good news is that there are

means to block these components on your browser.

Most browsers provide you with an option to block

these attacks. There are other harmul scripts that

can take you by surprise. These appear to be helpul

links and ads on the site that tempt you to click on

them. On clicking, they set to work. So make sure that

you click only on relevant links and objects on your

browser so as to keep away rom harmul scripts such

as these. These links can also be displayed on public

orums as HTML tags and ash ads.

EMAIL THREATS: Emails are the easiest way to get a

fle rom one end to another. The sad part is that it is

used to get some rather fshy fles across sometimes.

Make sure that you do not download fles that have

been sent as attachments rom sources that you do

not know. It can be a virus or another harmul fle that

AVG, Kaspersky, McAfee and Norton are the most common anti-viruses programs used as a first leveldefense. Though they are capable of functioning on their own, it is also very important to update them

regularly to keep them up-to-date with the latest threats.

will claim to be something else, like a riend's wedding

photograph or a calculator application. Downloading

and installing it can be disastrous or your system.

Spoofng is also a popular technique among

attackers to penetrate a system. Spoofng means

sending an email to a victim by disguising yoursel

as someone else. This leads to the problem o

compromising private inormation - by means o a

reply - to the sender, who is actually the attacker in

disguise. Spooed emails are really hard to tell rom

original ones since they can pose as anyone you would

trust sending personal inormation to.

For instance, an attacker may ask you to mail him

your current passwords and login details or even tell

you to change the same, while posing as your network

administrator. Home networks are sot targets or such

ingenious attacks.

FILE EXTENSIONS: It is a common practice to stay

away rom fles like EXE and COM since they are most

common viruses. However, there are means o ooling

you that can make fles appear to be o a certain

ormat while they actually are o a dierent fle ormat

altogether. So the fles that you will see may appear

to be, or instance, 'love-letter-or-you.txt' when it

is actually 'love-letter-or-you.txt.vbs'. Many viruses

appear in some rather harmless, non-executable

ormats. To tempt you into downloading them, they

may appear as MPEG, AVI or even MP3 fles. In actual

orm, these will be VBS script fles.

SNIFFING: 'Packet sni ng' or 'sni ng' occurs when

attackers capture data that is being sent over a

network, by intercepting it. This can give away

crucial inormation like sensitive mails and login

details. Sni ng is oten used against banking and

e-commerce sites so as to get sensitive monetary

inormation. Encryption and decryption o data

packets is the best way to get data across a network

without attracting the attention o attackers.

BACKDOOR ATTACKS: These attacks are oten carried

out by well-equipped attackers. Every system has

a backdoor that can easily be penetrated without

much problem. Certain tools such as BackOrifce and





Netbus are easy-to-use tools or those seeking an

entry into a computer network. Home networks are

eeding grounds or such attackers. They can even

dig into administrative systems and change certain

confgurations and use them to their advantage.

The above mentioned attacks are just broader classes

o more sophisticated actions taken by attackers to

penetrate a system.

HOW DO WE PROTECTOURSELVES?

The ollowing are some basic precautionary steps to

keep away rom network based attacks.

UPDATE ANTI-VIRUS APPLICATIONS: Make sure that

you update your anti-virus suite oten so as to remain

up-to-date with the latest threats on the network and

the Internet.

ENSURE STRONG ADMINISTRATIVE RIGHTS: I

you have a network administrator, make sure that

his system is capable o handling the privileges well.

Ensure that your system is saely shielded rom all the

harmul fles on the network.

USE FIREWALLS TO BLOCK PORTS: Firewalls are

great tools to block certain ports rom being accessed.

DO NOT USE UNKNOWN FILES AND APPLICATIONS:

Avoid using fles and applications that have come to

you rom unknown sources. I they arrive by email, do

not download or open them.

MAKE FILE EXTENSIONS VISIBLE: By deault,

Windows disables the fle viewing o fle extensions.

However, to avoid attacks, it is necessary to see what

ormat a fle actually belongs to. I you use Windows

XP then open 'My Computer'. In that click 'Tools |

Folder Options'. Click the 'View' tab. Uncheck the 'Hide

extensions or known fle types' checkbox. However,

this may not make all the extensions visible.

DISABLE JAVA AND ACTIVEX SCRIPTS: As seen

earlier, scripts like ActiveX can cause executable

viruses to enter your system once they are installed.

Hence disable them i possible.

BACKUP YOUR DATA: It is always critical to maintain

backup copies o your data so that they can be

recovered in case o loss.

TURN YOUR PC OFF WHEN NOT IN USE: There is no

way that a switched o PC can give away any data or

be attacked. Hence, keep it o i you are not using it. I

you eel that there is something absolutely dangerous

on your network then unplug the network cable ater

consulting your administrator.

KEEP A BOOT DISK FOR EMERGENCIES: The worst

case scenario can be your computer's system fles

being corrupted. Hence it is important to make a boot

disk to recover it at such times.

Firewalls are often bundled with anti-virus sui tes but can be found as st andalone applications as well.They help you keep your PC safe from notorious access points on the network. You need to understand

the concept of using logical ports on your computer before you configure Firewalls.

As the population o netizens grows at a rapid

pace, the need to be all the more vigilant and careul

about the nature o inormation shared with the world

at large is the need o the hour. Here are a ew simple

things that you can keep in mind to enjoy your online

networking experience in a sae and clean way!

ADD THE PEOPLE YOU KNOW: Social networking is

a great way to catch up with your long lost riends,

and even make some new ones. But there are certain

things you need to keep in mind rather than going

on a hunt to make new riends. As a thumb rule, don't

add random people. There is no way o knowing their

real identity since many o these users don't even

upload their own photographs. You might fnd ar

more genuine people at a bar rather than on a social

networking website. Random people don't eel bad

i you reuse their requests. There are also certain

people who add you rom your riend's riend lists.

Make sure you ask your riend who this person is and

why he wants you on his list. Also i you eel that your

Man being a social animal, the interaction

o like-minded individuals led to the

ormation o civilization that we are now a

part o. While keeping pace with the technological

advancements, the entire world has shrunk

tremendously and geographical distances can

now be nullifed with the mere click o a button.

Just like the concept o communicating is as old

as civilization itsel, so is the concept o social

networking as old as the Internet.

There were online social exchange mediums

(BBS) like USENET (1979), and LISTSERV (1986) that

enabled users to communicate with each other

through comments and posts, there were also

webhosting services like Yahoo! GeoCities (1994)

which enabled users to air their thoughts online.

While the ormer laid a frm oundation or the

be breached by adding certain known riends, make

a prudent decision to decline their request. I you are

pestered too much ater declining requests rom a

particular user, eel ree to report them.

POST MESSAGES WITH CAUTION: With the

Twitter and Facebook ever rising by the second,

the 'disconnect anxiety' seems to be increasing

signifcantly especially among the youth. Most o

these social messaging services extend unctionalities

to devices like Palm tops, BlackBerrys and cellular

phones, in turn adding to the number o addicts. This

urge o technophiles to keep glued into their account

is a big cause o psychological concern. Several

users subscribe or text alerts alerting them on every

post or comment they receive. Moreover, this kind

o technology enables people to update each and

every incident o their lie quite intricately and rather

quickly. This kind o behavior poses a threat at many

levels: frstly it shows the psychological well-being

o a person. I you seem low or depressed on your

posts, you can be taken advantage o. There have

also been reported incidents o houses being burgled

by keeping track o tweets and post updates while

people are out on long vacations. Tweets / posts like

'Out on a two week long vacation to the Bahamas',

coupled with a list o your likes-dislikes (an indicative

o your possessions) and coupled with your location

details ensure that you are laying a trap or yoursel.

Always remember even i you don't add any direct

personal details like your house address, a small

amount o probing along with your IP address can

reveal a lot about your browsing locations.

PROTECT YOUR PERSONAL PICTURES: I pictures

speak louder than words, what better way to share

memories than with photographs? But when you

upload pictures, make sure you know how sae

they are rom prying eyes. Your pictures might

be used without your permission violating copy

right issues. On a more serious note, there have

been many reported instances o how pictures o

unsuspecting social networking users have been

used or pornography, child racketing and other

heinous crimes. Most o the networking web portals

provide you with personalized sharing options. It is

a recommended that you don't share albums with

people out o your riend circle. I your riends are not

comortable with their pictures appearing in your

album, respect their privacy and take them o your

albums immediately. Always remember, even i you

delete images rom your profle you cannot be 100%

sure that those images are not still somewhere on the

server or have already been misused.

Although you can set the content access parameters from the Settings page directly, these contentsdon't include your photo albums.

Click the 'manage' link appearing near the 'Privacy' section of the 'Settings' tab of your account page

SECURE YOUR JOB: Business networking sites are the

newest rage among young corporate workers. They

use these as a tool to build social networks or

business building or job hunting. But there is a real

threat i you are joining a rival frm and promptly

bit tough to answer unwarranted questions especially

i your ex-colleagues orm a part o your network.

Moreover, the recommendations you receive here may

not be too useul i companies preer the older and

more traditional type o job reerences.

SECURE YOUR INTERESTSONLINE:Listed below are a ew pointers on how you can set

the privacy option on some o the most popular web

portals around the world.

SECURITY ON ORKUT.COM: In its early days, Orkut

had very ew privacy policies. But as time went by and

the nature o security-lapse related crimes came to be

known, Orkut has strengthened its security options.

To alter your security settings, login to your Orkut

account and go to your profle page. Make sure that

you haven't specifed details that give out too much

personal inormation especially your email address as

it is prone to spam attacks. Save the changes and click

the 'Settings' option which is the second last option

on the panel appearing below your uploaded profle

picture. The 'Saety flter' on the website is turned

on by deault to protect your account rom being

spammed with x-rated content.

Although this is not a recommended practice, you

can go to the 'general' tab o the 'My Settings' page,

and check the 'show all content' under 'saety flter'

instead. Go to the 'privacy' tab o the web page to

manage and monitor who can access the contents

on your profle. Change the listed setting as per your

requirements.

Also note that you can set privacy on uploaded

images or every album individually. Go to the

'notifcations' tab to set the way you wish to be

inormed o any external activity on your account.

The 'chat' tab enables you to speciy how many

people can chat with you. You enable or disable chat

settings or individual users, or or groups as a whole.

PRIVACY ON FACEBOOK.COM: Facebook has been

one o the most popular websites or most youngsters,

as it whizzes past its contemporaries like Twitter, Orkut

and MySpace in terms o popularity. With so many

users to satisy, it becomes extremely necessary to

keep their privacy intact.

You can view and change your Facebook privacy

settings by logging onto your Facebook account. Once

Concealing or selective viewing of data becomes all the more essential when you are building aprofessional network.

If you tweet incessantly, pay close attention to what you share to keep yourself safe from those

stalking you online.

As one of the most interactive networking sites, MySpace provides auto responders to connect to

your audience even while on vacation.





your profle page is displayed, click on the 'Settings'

link appearing next to your email ID. On the 'My

Account' webpage, click the 'Privacy' tab. You can

also set notifcation options under the 'notifcations'

tab to set the way you wish to be inormed o any

external activity on your account. You can monitor

the Facebook 'chat' eature by clicking on its tab and

setting the options under the 'Options' link on the

pop-up menu.

PLAYING IT SAFE ON MYSPACE: Beore Facebook

revolutionized the world o social networking,

MySpace took the Internet by storm. Being one o the

frst entrants in this feld, MySpace also is one o the

frst websites dedicated to musicians. Keeping in mind

this specifc target audience, the privacy options are

scattered across the account's setting page.

Log on to your MySpace account and click the 'My

Accounts' option. Click the 'Privacy' link to change the

general profle level settings. You can control your

notifcation settings by clicking the 'notifcations' tab

to set the way you wish to be inormed o any external

activity on your account. Finally or urther privacy

options, click on the 'Miscellaneous' link and change

the settings as required.

SURF CAUTIOUSLY ON LINKEDIN: A relatively newer

entrant into this market, LinkedIn plans to redefne the

Word business networking. The website encourages

people to create networks with those whom they have

had any type o proessional connection. It helps users

secure recommendations and new jobs as per their

current profles.

Log on to your LinkedIn account and click the

'Account & Settings' option. Here you can change all

the possible options in this page alone. Click on any

links listed under the 'Privacy Settings' section o the

page and edit the settings as per your requirements.

TWITTERING WITH CARE: Twitter has revolutionized

the world o social networking by combining the best

o networking and texting in a brand new genre called

micro-blogging. Most people get into trouble because

o the contents o their tweets. Houses get burgled

into, young girls have been reportedly molested and

political careers threatened because o irrational and

excessive twittering.

Firstly, know the people who ollow you i you

are twittering about personal details. Log on to your

twitter account and click the 'settings' tab and change

the settings as required. You can block people rom

ollowing you on the website.

However, there are not too many restrictions on

the site and any one can view your tweets irrespective

o the act that they don't ollow you. And hence you

need to be extra cautious beore you tweet details

relating to your location, residence or other

intimate details. What adds to this problem is the

growing support or Twitter on handheld devices.

SECURE YOUR IDENTITY ON HI5! Hi5! is one o the

oldest social networking websites and is one o the

earliest o its kind. The privacy settings are the most

easily navigable through this web portal. Just log into

your Hi5! account and click the 'Privacy' link. Click on

Protect your fundsfrom being phishedPhishing is a technique through which passwords and other conidential details are stolen in order to hack into bank accounts and steal money rom victims. By ollowing these simple tricks, learn how to protect your money during online transactions.

B Y K A M A K S H I S

1USING THIRD PARTY

APPLICATIONS

WHILE there are several third party applications which help

you protect your interests while purchasing and perorming

transactions online, there are also several browser specifc

add-ons that you can enable within your browser. One such

tool is the 'Netcrat Toolbar', which is available only or the

Internet Explorer and Mozilla Fireox browsers as o now. These

applications help you to report raudulent sites, and help you

generate lists o the phishiest web hosts, worldwide.

2READ BETWEEN THE LINES

MOST email service providers today have a strong

in-built spam guard. Yet, i a scam mail still manages to make

its way to your inbox, may sure you read the contents twice or

thrice. Every credit company or bank has a specifc pattern o

correspondence. I you fnd anything out o the ordinary or see

too many spelling mistakes, it is advisable to check with your

bank beore responding to such emails. I you fnd such emails

fshy, delete them without a second thought.

3CHECK THE SENDER NAME AND

ADDRESS TEXT

WHENEVER you get an email rom a clean source, the sender's

name would appear in your inbox. I you fnd an email ID

instead o the sender's name, you can delete the email without

even opening it. Similarly, i the email is addressed to an ID

like '[email protected]' or reects a part o the email ID

like 'Dear john9999' instead, such mails are usually sent rom

unreliable sources which send out bulk mailers as spam. Avoid

opening such emails, and even i you do, don't download the

attachments that are sent along with them.

4VERIFY IF THE EMAIL IS A SCAM

MOST email scam messages are marked as spam and are

diverted away rom your inbox. I they aren't, and the email has

genuine logos o well known companies, there might be a chance

o them deceiving you. I you don't get a convincing response

rom the source itsel, you can check on the Internet whether

these mails are indeed scams. Various web portals like 'www.bi.

gov/cyberinvest/escams.htm ' and 'www.hoax-slayer.com' provide

a comprehensive list o known scam emails. Check them and only

then respond to such emails.

5CLICK ON LINKS WITH CAUTION

THE oldest way to lure unsuspecting victims to submit

their details is by providing links in emails with names and

organizations that appear to be original. Irrespective o whether

the link lands you at a credit card site or an Internet banking site, it

is advisable to practice sae browsing while surfng the net. Never

click on the link rom the emails, instead type the address directly

into address bar o your browser yoursel. You can browse more

saely i you log in to each website through a dierent window.

Make sure that you log out o the site once you are done. Delete

your browsing history and temporary Internet fles periodically to

remain completely sae.

6CHANGE PASSWORDS REGULARLY

ALTHOUGH you have created passwords which are

deemed to be sae and strong, it is a recommended practice to

6 HANDS ON 10 TIPS




keep changing your passwords periodically. Most people who

phish into your accounts are not your riends, and they can hack

into your account without you telling them your password.

Make sure that your password is not alternating between two

values alone; your password should not resemble the last

three passwords that you had once set. Ater you change your

password take due care to remember it. In most o the credit

card or Internet banking websites, your account will be blocked

i you enter the wrong passwords or more than three attempts

consecutively, irrespective o the time o your last attempt.

7LOG INTO ACCOUNTS REGULARLY

LOG into all your accounts regularly even i you do not

want to make any purchases or transactions. Most people take

their account statements too lightly. Read and veriy each debited

and credited amount appearing on your statement. I you fnd

anything remotely suspicious, report and clariy it with your bank

immediately. I a person has access to your account, he will not

phish into it right away. Staying observant will also help you cut

down on unnecessary expenses, and help you keep a tab on your

spending habits.

8USE THE LATEST VERSION OF YOUR

WEB BROWSER

ALWAYS use the latest version o your current web browser.

These browsers come equipped with powerul and updated

anti-phishing flters that help you blacklist dubious websites

and also avoid browsing to already blacklisted websites. Many

browsers also have additional add-ons that you can download

and utilize. Use the latest versions o Internet browsers. Most o

these contain their own anti-phishing flters and blacklists to keep

you sae while carrying out online transactions.

9UPDATE ANTIVIRUS AND FIREWALL

PERIODICALLY

MOST o the recent anti-virus, anti-spyware and frewall

applications come equipped with upgraded support to tackle

raud related security issues. While the version in your system

is prepared to secure your PC rom all the viruses known at the

time o its creation, the updated packages available add newer

codes to secure your data and online activities rom more recent

and lesser known threats even more eectively. Most anti-virus

applications post periodic updates on their website which you

can easily download and incorporate by yoursel.

10USE STRONG PASSWORDS

THE cardinal rule o password selection is that you

should always pick a password that is easy or you to remember

and di cult or anyone else to decode. Also your password

should have a healthy mix o alphabets (both upper and lower

cases) and numeric values. That eectively means that you should

avoid using your frst name, last name, amily name, nickname

or date o birth as passwords. Also avoid using confdential data

like your ATM pins, CVV or social security numbers as passwords

either. Shu e your passwords well. Don't pick the same username

and password combination or all the websites you sign up to

or email accounts. I one gets hacked into, it's not so di cult to

guess others. Don't share your passwords with any one. I you are

going to take so much trouble to pick an appropriate password, it

is rather wise to keep it to yoursel.

10 TIPS HANDS ON 17




Protect your laptop while on the goOne reason people choose laptops over desktop systemsis portability. However, with portability come threats likethet, natural hazards and other external problems. Hereare some helpul tips to make sure that your laptop issae while you're outdoors.


1USE TRACKING AND CALL BACK

APPLICATIONS

TO help you in times o need, in this case, in thet, we have

scores o applications that can ensure that you have some hope

o your laptop being returned to you ater being burgled. To do

so, these programs use techniques like sending inormation o

the laptop's current location; this helps in tracing them. Other

services include call-back applications that call the owner rom

the laptop, thus giving away its location. Some notable tools

include SecureIT, Stealth Signal and CompuTrace.

2USE CABLE LOCKS

CABLE locks are quite an obvious choice or those who

eel that their laptops are not sae in an o ce or a caé. These

are used especially in cases where you need to leave your laptop

unattended or charging. Most o the laptops available these

days come with a Universal Security Slot (USS). This slot is used

to attach a cable lock or a laptop alarm. These devices aren't

expensive and can keep away small-time thieves.

3USE DOCKING STATIONS

DOCKING stations are another great means o securing

your laptops in your absence. While in an airport, hotel, caé,

train station, a client's o ce or any other place that would

require you to get your laptop out o its bag in order to work on

it, you could always use these to ensure that your laptop is just

where you put it when you let the place. O course, this means

o protection is eective only or a temporary period. Given a

bit more time, any thie can get away with your laptop and your

docking station to top it o.

4PERMANENTLY TAG YOUR LAPTOP

MAKING an impression o your name and the name o

the organization that you work or can pay o in times o thet or

loss. You can get it embedded or engraved on your laptop rom

a proessional studio or use a label or a sticker with your personal

inormation. I you eel that these measures would be too crude

and would mar the sleek look o your laptop then you can invest

some more money and go in or tamper resistant 'commercial

asset tags'. Since these are made o metal there's little chance o

them peeling o or tearing. This will also help in recovery i you

leave your laptop lying somewhere. Many people also resort to

putting their address and contact number on the laptop.

5USE SCREEN GUARDS TO HIDE

YOUR DISPLAY

SOMETIMES the inormation we're dealing with on our laptops

is extremely crucial and cannot be shared with others. Such

inormation like bank transaction details, sensitive letters and

notes and other such personal inormation have to be protected

rom those who would like to use it or all the wrong reasons. To

avoid such attacks on your sensitive inormation we have screen

guards. These cover your screen rom the sides and above so that

you do not ace the problem o people peeping into your screen,

over your shoulder. Adding screen guards however, can cause

the weight o your laptop to increase and will also add to the

number o accesories that you have to carry along.

6AVOID USING LAPTOP BAGS

IT is common sense to keep the thieves rom knowing

that you have a laptop with you in the frst place. Hence, you

8 HANDS ON 10 TIPS




H e m a l i L i m b a c h i y a

should avoid carrying your laptop around in the regular carry

cases that make their contents quite obvious (especially those

that come with the laptop rom the vendor). Sometimes these

cases even have the brand logo o the laptop they contain,

ashing around in order to endorse it. Many laptop bags are

shaped like regular rucksacks, in order to thwart eorts o thet.

Also make sure that you carry it with you while traveling in

mass transit rather than letting it go along with the rest o your

baggage. However, one should make sure that you do not place

your laptop in an absolutely compact bag in order to conceal it.

The bag should be padded and spacious enough.

7DISABLE BLUETOOTH AND

INFRARED PORTS

WE may eel that it isn't necessary to turn o access to your

Inrared and Bluetooth ports, when not in use. However, it is a

very good practice to make sure that these ports are disabled

since we may unknowingly accept harmul fles, which may not

always be intended or us, rom these ports. It is also possible to

hack into PCs using Bluetooth or Inrared. The Inrared port can

be disabled rom BIOS as well.

8DO NOT LEAVE PASSWORDS

WRITTEN ANYWHERE

ONCE you have gone through the stretched, cumbersome

process o setting up the security channels or your laptop to

keep it away rom possible attacks, you have a whole new task

o keeping the inormation sae. For instance, many people

keep little scraps o paper that have the password or access

keys scribbled on them. These help in remembering these

codes incase the user has orgotten them. However, in case this

inormation alls into the wrong hands you can expect trouble.

Make sure that you handle such data careully.

9

SECURE YOUR LAPTOP WHILE ON

THE ROADTRAVELING in a car with your laptop tucked saely beside

you may not seem like an opportunity or a possible attempt

o robbery, but this isn't always so. There are times when you

will need to leave your car. Do not keep your laptop near

the window. Always make sure that the windows are closed.

However, there have been instances where laptops have been

stolen by breaking the car window. Resorting to the use o a

cable lock will come in as a great alternative. It will also help in

avoiding misplacement or dropping your laptop.

10

CAUTION WHILE TRAVELING BY AIR

UNLIKE the vulnerabilities that your laptop aces when

in a car, air travel needs more caution since you are under threat,

both inside as well as outside the plane. Outside, the airport is a

eeding ground or laptop thieves. It is quite easy or them to lay

hands on your laptop bag by creating a minor distraction or by

simply picking it up rom your baggage check beore you can do

so. It is better to carry your laptop with you while ying rather

than letting it go with the rest o your baggage. Also, while in

the plane, keep your laptop close to you. It is quite possible that

there may be a thie on-board. Passengers oten doze o during

long ights, thus giving thieves a good chance to steal their

things. Just keeping your laptop with you is not enough, also

make sure that you are alert o co-passengers.

INTERNET EXPLORER 8

01USE IE8 ACCELERATORS

Internet Explorer 8 has an exciting

new eature called Accelerators, that

can solve your browsing problems.

Accelerators basically quicken your

'website search' by giving you direct

links to popular web search tools that

can be opened with a mouse click.

When you install Internet Explorer 8

you are provided with Accelerators

that provide you with only those sites

that are a liated to Microso t, such as

Windows Live. Here's how to go about

with using Accelerators:

Open up any webpage on Internet

Explorer 8. Make sure that it is a

site that has various elements like

images and textual inormation. The

best example would be a Google

search results page.

Right-click on a link on the page

and in the context menu, you will

see the 'All Accelerators' option. A

tray will open up with an option o

Accelerators that are available.

Using these Accelerators you can

receive a direct translation o the

page to the language o your choice.

You can also blog the article that

you are on as well as e-mail it to

your contacts.

To look or more Accelerators

or Internet Explorer 8 click 'Find

More Accelerators' under the 'All

Accelerators' menu. The browser will

open up a page that contains links

to an add-ons page that contain

various Accelerators that can be

added to the browser. Simply click

the 'Add to Internet Explorer' button

beside the ones you would like

to add. A dialog box will appear

on your screen asking you or a

conirmation o the same. Click 'Add'.

The add-on link will be added to

your list o installed Accelerators.

To conigure it, again right-click on

the page and click 'All Accelerators |

Manage Accelerators'. A new dialog

box will appear on your screen.

Simply click on the one you installed

and click the 'Set as deault' button

i you want to set this as the deault

Accelerator. You can also 'Disable',

'Enable' and 'Remove' Accelerators

rom here.

Click 'Close ' to exit.

MOZILLA FIREFOX

02VIEW TRUSTED SITES

Mozilla Firefox has an in-built deense

mechanism that decides which sites

are sae to visit and which aren't. The

browser allows you to customize your

security to a level that you fnd suitable

in the ormidable Web environment

that has scores o viruses and other

threats oating around. It's called WOT

(Web O Trust) and is available as a

Fireox add-on. The representation

o threatening sites is quite easy to

understand while using WOT since

it color codes the sites based on the

levels that you set. Follow these steps

to install WOT into Fireox,

Visit https://addons.mozilla.org/

en-US/ireox/addon/3456

Click 'Add to Fireox '.

Click 'Install ' on the dialog box that

appears on your screen.

Ater the add-on is installed you will

have to restart Fireox.

Once you restart the browser you

will be redirected to the 'welcome'

page o the WOT site. You will come

across our radio buttons that ask

you to select the level o protection

that WOT should use.

Select your level and click 'Finish '.

A green circular logo o the

application will appear on your

Navigation toolbar, beside the

address bar. Click this button and

click on the rating meter to mark the

'Trustworthiness', 'Vendor reliability',

'Privacy' and 'Child saety'. You can

do this by clicking on the color-

coded rating bars.

To view the overall score o the site

as per rating o users simply click the

'View scorecard or ratings detail' in

the dropdown box.

WOT can thus help you gain a better

understanding o what risks you

run into whenever you visit certain

websites.

03MANAGE YOUR

PASSWORDS SMARTLY

Passwords are always a problem

to handle. Firstly, picking the right

WEB

One of the most useful things you can do with Accelerators is translating a webpage in real-time. By default

IE8 translates using 'Live Search'.01





password always makes us scratch our

heads, and then comes the problem

o remembering these passwords

over a period o time. This problem

arises because most o us have multiple

IDs (or logins) on dierent sites, and

with all the hype o keeping away

rom using the same password in

multiple sites.

There is however something that

can help us out o this mess without

asking or much. It's called 'LastPass

Password Manager'.

It is a Mozilla Fireox add-on

that supports versions rom 2.0 to

3.7. Follow these steps to install

and confgure your passwords with

LastPass.

Visit https://addons.mozilla

.org/en-US/freox/addon/8542.

Click the 'Add to Fireox (Windows)'

button.

The installation dialog box will

open up. Once the installation is

complete, restart Fireox or the

changes to take eect.

Click the logo on the ar right corner

o the navigation toolbar. It can be

ound on the right o the search

box. It is shaped like a black square

with a white password character

embedded on it. You will be asked

or your email address and or a

master password.

Click the 'Create an account' link

on the 'LastPass Master Login'

dialog box.

This will launch the setup window.

Select your language o choice and

click 'Create an account'.

On the next orm enter the details

that are asked like your email

address, master password and

other ields. Your master password

will help you take control o all

the inormation you share with

LastPass, such as passwords o

various sites that you sign up or.

Check all the checkboxes at the

bottom, especially 'I have read and

agree with the terms o service

and privacy statement' and 'I

understand that my encrypted data

will be sent to LastPass'.

As you ill in the master password,

you will notice that the bar

below the ield is illed with color

indicating the strength o the

password. The strongest password

is that which is illed with color.

Click 'Create an Account' again to

proceed.

Just to make sure that you do not

orget the master password that

you set earlier, LastPass will ask

you to reenter the password. Do

this and click 'Create an Account' to

continue.

The next options are crucial. Select

the irst radio button that lets you

choose the items that you want to

import.

Click 'Continue'.

A smaller dialog box will appear

with the list o logins that are

registered to the email address that

you had entered. Click 'Import' ater

selecting all.

Keep clicking 'Continue' on the

ollowing steps to complete the

registration process.

Once you have done this, the

completion o your registration process

will be confrmed. Make sure that you

do not share your master password

with anyone. Every time you visit a

page that requires you to log in simply

ensure that you have signed into

LastPass. The application asks you

to enter only the master password.

The rest is taken care o as your email

address and password is entered

automatically ater a brie reerence to

the application's list o log ins.

After selecting the language click 'Create an account'. You will be redirected to the next form where youhave to enter details.04

WHAT DOES DATA

ENCRYPTION MEAN?

Encryption is a process o

converting normal text into

what seems like a sequence

o random text also known as

cipher text. The conversion o data into cipher text requires

certain ormula known as

algorithms. There are several

algorithms available to help

with this conversion. The

amount o time taken to

encrypt the data orms the

basis o the encryption. The

Advanced Encryption Standard

(AES) was made available to

the public in around 1998 and

was used by the military. It is

a 256-bit encryption standardand can encrypt and decrypt

at a mean speed o around 36

mbps. AES-Twofsh-Serpent is

a very strong encryption and

can encrypt and decrypt only

6.6 mbps on an average. This

also depends on the system; a

aster processor will perorm

the task much aster. The RAM

is also a major actor.

WHAT IS ACTIVEX?

ActiveX is basically a

technology that is used by

Internet Explorer. It allows

applications to be used by

the browser. An ActiveX

component may alreadyreside on a Windows system

or it may be provided as a

downloadable object. This

enhances the unctionality

o web browsing. On the

other hand, it may also pose

as a security threat i it's

not properly implemented.

Though it's quite useul, it

also increases the chances

o you being attacked.

Also, installing a Windows

application introduces thepossibility o ActiveX controls

being installed on the system.

Hence one should be aware

o or completely block these

applications rom being

installed through the browser.

STEP 2

CONFIGURING MOZILLA FIREFOX

FIREFOX has gained popularity over the years and is being used by many. But like Internet Explorer,it comes with security options that need to be confgured or optimum security. To confguresecurity settings, ollow the steps below.

WHAT ARE BROWSER

PLUG-INS?

Plug-ins are extra applications

that can be used by a web

browser. By deault most

plug-ins are not installed since

it may not be required by theuser and at the same time it

also keeps the browser light.

Most plug-ins are (by deault)

created by the browser owner

themselves. On the other hand

there are plug-ins created by

third party users to extend the

browser's unctionality. They

are similar to ActiveX controls.

The only dierence is they

cannot be executed outside

the web browser. Adobe Flash

player is an example o aplug-in. Downloading plug-ins

rom a third party might put

your inormation at stake since

the plug-in may contain code

to steal private inormation or

even harm your system. Hence

downloading a plug-in, only

rom the browser's deault

website is recommended.

STEP 1

FORMATTING USING LINUX

THERE are several means o ormatting your pen drive without letting the virus inect your PC. Themost popular technique is to ormat it using operating systems other than Windows, such as Linux.

STEP 2

TACKLING THE INFECTED 'AUTORUN.INF' FILE

VIRUSES oten travel across computers on USB drives by taking the orm o the 'autorun.in' fle. This fle is used to launch the 'Autorun' dialog box when the pen drive is inserted into the USB port.Once inected by such a virus, a copy o the same is made on all drives o the aected PC. Everytime the drive is inserted, the virus is executed. Hence it is best to prevent the 'Autorun' eature inthe frst place. Ater doing that we will see some tools that can help avoid inections.

The reason we use Linux1.

as the primary means o

virus elimination is that

there aren't too many

threats that can aect a

Linux machine.

Insert your pen drive,2.

locate the 'autorun.in'ile that is inected and

simply delete it rom

Help! I do not want

Windows Firewall

+ CONFIGURINGWINDOWS FIREWALL

PROBLEM:

I had earlier disabled Windows Firewall

on my Windows XP system because I

ound it quite annoying. However, I have

been advised that it is quite an important

tool and that it will help in maintaining

a frst level o security or my computer.

How do I enable it again and reconfgure

it to unction normally? Also, I would

like to know how to add programs to the

'exception list' o the frewall so that it

doesn't block these applications without

my permission in the uture.

SOLUTION:

One o the main reasons we have

people disabling Windows Firewall is its

intererence with certain, commonly-used

applications. In act, some applications

even advise users to disable Windows

Firewall or their smooth unctioning.

This does pose a threat or those who do

not have any other security applications

or anti-virus suites installed on their

systems; since Windows Firewall is the

deault, frst level security provided by

Microsot or its operating systems.

It is best advised not to disable the

frewall but rather confgure it to suit

your needs. This also includes adding

requently used applications to the

exception list o frewalls so that it doesn't

interere with their smooth unctioning

anymore. Follow these steps to

reconfgure Windows Firewall and create

an exception list:

Make sure that you are logged into the

administrator account on your computer.

Windows Firewall can be handled by

administrators only. Guest accounts do

no have access to its settings by deault.

Click 'Start | Run'.1.

In the textbox, type in 'wscui.cpl2. '

and click 'OK'.

The 'Windows Security Center3. '

window will open up.

Click the 'Windows Firewall4. ' logo

at the bottom under the 'Manage

security settings or:' section.

The 'Windows Firewall5. ' window

will open up. Click the 'On

(recommended)' radio button to

enable your irewall again.

Make sure that the 'Don't allow6.

exceptions' checkbox is not

checked.

Click 'OK'.7.

This step will enable the previously

disabled frewall. Now i you want to

add exceptions to the frewall so that

it doesn't block any application in the

uture, ollow these steps:

Follow the above procedure to open1.

up the 'Windows Firewall' window.

Once it opens up click the 'Exceptions2. '

tab.

In this, click the 'Add Programs3. ' tab.

A list o programs will be displayed4.

in the next dialog box that appears.

Select the name o any application

that you use requently or one that is

oten blocked by Windows Firewall.

I you cannot ind the name o the

program in the list o applications,

click 'Browse' and manually locate it.

Click 'OK 5. ' once you're done.

Now run the application to check i

Windows Firewall still intereres with it.

I you still experience problems with the

application running then you will have to

resort to the cumbersome procedure o

disabling Windows Firewall while using

Windows Firewall is a great security application, however there are times when this helpul tool can turn hostileagainst us and bring out problems rather than solutions.

it and then enabling it again once

you're done.

It's better to get yoursel a complete

third party frewall that is compatible

with your application.

You may also need to add a port to

the list o allowed exceptions. Reer to

the next problem or an elaboration on

the same.

+ ADDING PORTEXCEPTIONS

PROBLEM:

I have Windows Firewall enabled on my

PC but because o this certain ports are

blocked. A sotware application I use does

not work, since it requires a particular

port to be opened. Does Windows

Firewall have a provision to allow only

particular ports to be enabled? How can I

tell which ports are being used?

SOLUTION:

Yes, Windows Firewall allows you to

speciy individual ports that can be

accessed by third party applications

even when it is running. However, to

address this problem you need to frst

determine which ports are required by

the application that you're running.

There are a couple o means by

which you can fnd out which o the

ports (which are normally blocked by

Windows Firewall) are needed to be

opened. You can contact your program

vendor or assistance on which ports

should be enabled or use a simple DOS

command to fnd out which ports are

being accessed. Follow these steps or

the same:

Launch the application that's1.

causing you problems.


Type in 'command3. ' and hit [Enter].

In the command prompt enter 'netstat4.

-ano > netstat.txt'.

Hit [Enter].5.

Similarly, enter 'tasklist > tasklist.txt6. '

Open both the iles, 'Tasklist.txt7. '

and 'Netstat.txt' rom the location

speciied in the DOS prompt.

In the 'Tasklist8. ' ile, look or the name

o the program that was causing

problems. Beside it, you will notice

the column that enlists the PID (port

identiier) that it uses. In this example

(below), you will see that it is a

program called 'myprog.exe' and that

the PID is 680.

Look or the similar PID in the 'Netstat9. '

ile. I the port numbers used is

more than or equal to 1024, then it

is evident that the application uses

more than just a single port. It pretty

much means that you will not be

able to resolve the issue by opening

individual ports.

I in the above steps, you notice that the

port number is lesser than 1024 then

carry with these steps to block individual

ports:


In the textbox, type in 'wscui.cpl2. ' and

click 'OK'.

In the 'Windows Security Center3. '

window that opens up click the

'Windows Firewall' logo at the bottom

under the 'Manage security settings

or:' section.

The 'Windows Firewall4. ' window

will open up. In this, click the

'Exceptions' tab.

Click 'Add Port'.5.

Type in the details o the port that6.

you got either rom your vendor or

by using the procedure above.

Click 'OK'.7.

The program should work ine now8.

even with Windows Firewall enabled

and running.

After clicking 'Add Program' a dialog box with a list of applications will appear on your screen. Click 'Browse' if youcannot find the application you are looking for.

Enter the name of the application, the port number and the type of protocol (TCP/UDP)

and click 'OK'.

Look for the common port identification number 'PID' in both the 'netstat' as well as the

'tasklist'. This will help you determine the port in the 'netstat' file.

Q WHAT IS RAID?

A RAID is an acronym or

Redundant Array o Inexpensive

Disks. It is a technology that allows

computer users to gain a high level

o reliable storage space rom

low-cost PC-class disk-drive

components. This is done by

arranging devices into arrays or

redundancy. It is basically used as a

term or computer data storage

schemes that can divide and

replicate data across dierent hard

disk drives. There are dierent

schemes or example, RAID 0, RAID 1, etc. Its design generally involves achieving two

goals. The frst being increasing data reliability and the second, improving the input/

output perormance. When there are multiple physical disks set up to use RAID

technology, they are usually said to be placed in a RAID array. This array thus gives out

data across dierent disks, but the array that is used is seen as a single disk. The best

part is that RAID can be used to serve several dierent purposes.

Q WHAT IS A VIRTUAL FIREWALL

A FEW years ago, when virtualization was used or development and test

organizations, security was not an issue. It was used or easy access to multiple

operating systems that were installed on a single server. Since it was successul,

virtualization spread to production-oriented

data centers within major corporations. It

helped create networks o virtual machines

within physical servers. Today as we see that

virtualization has moved to the cloud, there

is a high risk or exploits. Virtual frewalls are

built specifcally to lessen the risks o virtual

networks. It is basically a packet fltering

frewall that is installed as a sotware in a

virtual environment. It also provides control

o inter-VM tra c. Hence it can protect and

lessen the risks o viruses, worms and Trojans

in a virtual environment.

Get to know what a Virtual Firewall is. Also learnmore about RAID and SNMP.

SNMP stands or Simple Network

Management Protocol. It is basically

used or network management

purposes. It can monitor devices

attached to a network. It is basically

a component o the Internet Protocol

Suite as defned by the Internet

Engineering Task Force. This protocol

consists o a set o standards that is

used or managing the network within

an organization. In an SNMP scenario,

one or more computers having

administrative privileges have the task

o monitoring or managing a group

o hosts or devices on the network.

The SNMP protocol operates in the

Application Layer o the OSI model.

SNMP uses ports 161 or the agent and

162 or the manager. The manager can

send requests rom any source port

to port 161 i.e. the destination port.

The agent will then respond with a

reply to the source port. The manager

receives notifcations like TRAPs and

INFORMs on port 162. The agent can

then generate notifcations rom any

ree port.
