A risk can be defined as a function of three variables:◦ the probability that there's a threat◦ the probability that there are any vulnerabilities◦ the potential impact

A threat is anything (man made or act of nature) that has the potential to cause harm

A vulnerability is a weakness that could be used to endanger or cause harm to an informational asset

Large companies have higher security budget (more than $1 million), have more technology in place, follow more strategic practices, but

The larger companies suffer more security breaches and bigger losses

According to IT Policy Compliance Group Research, 75% of all data breaches were caused by human errors

29

The Secret Healthcare Company lost an unencrypted CD holding personal and medical information of 75,000 members while sending it to a contractor firm

30

What could the company do to prevent data leak?

1. Continue to Develop and Deliver Security Awareness, Training and Education

2. Redesign Policies and Standards Framework and Content

3. Expand Processes and Methodologies to Integrate Security into the Enterprise

4. Create and Deploy Data Protection Practices and Solutions

5. Implement Vendor Management Oversight of Data Management and Contract Compliance

6. Develop Incident Handling Protocols and Manage Responses

31

Continue to apply the right organization model

Having consistent policies, procedures, and standards in place

Providing ongoing security training Looking for better ways to secure the

technology Strengthening the information integrity

in more proactive ways Executing the information security

'Credit card fraud' is one of many form of Bank fraud that involve credit cards, charge cards, or debit cards

34Source: 18

The fraud begins with either the theft of the physical card or the compromise of the account information

The compromise can occur by many common routes, including something as simple as a store clerk copying sales receipts

A) B)

35

The rapid growth of credit card use on the Internet has made database security lapses particularly costly; in some cases, millions of accounts have been compromised

40% of U.S. and European consumers have stopped an online transaction due to security concerns

36Source: 23

Since 2005, credit card fraud in the UK and America has increased by 350% on average according to Reuters

With credit card crime occurring across state lines, criminals often are never prosecuted because the dollar amounts are too low for local law enforcement to pay for extradition

37Source: 24

The cost of credit and charge card fraud - to card holders and to card companies alike - may be as high as $500 million a year

Everyone pays for credit and charge card fraud in higher prices, whether or not they are personally defrauded

In 2000, Visa trumpeted a list of security "best practices" for e-merchants that accept Visa cards

◦ It also announced its intention to verify merchants’ compliance

In October 2007 Visa introduced a new set of Payment Application Security Mandates

◦ Merchants now have time till July, 2010 to comply

40Source: 6, 17

1. Install and maintain a working firewall2. Keep application and operating system security patches up

to date3. Encrypt stored credit card data4. Encrypt data sent across the network5. Use and regularly update antivirus software6. Don't use vendor supplied defaults for password security 7. Assign a unique user ID to each person with computer

access 8. Track access to data, including read only, by unique ID9. Regularly test security systems and processes10. Restrict access to data on a business "need to know" basis11. Have a management or human resources policy that

addresses security in the workplace, such as doing background checks

12. Restrict physical access to authorized employees

In addition to other security measures (PIN, 3-digit security code, address matching etc) Visa introduced "Verified by Visa” for online transactions

Unique passwords or codes are required during Internet transactions to verify the user's identity

According to Visa's own research, 76% of customers wanted a password protected system to enable them to shop on the internet with total peace of mind, and this is the reason we have introduced Verified by Visa"

44

Standard cards Feature a static card

verification value written into the magnetic stripe

This number is not known to the user and is designed to verify that the card is present during a transaction

However, because it never changes, criminals can use stolen data from the magnetic stripe to produce cloned cards that would work until the issuer reissued the card

45

Contactless Visa cards Feature embedded

microchips that generate a unique code whenever the cards are used

The code is unique to each transaction, which means that criminals who manage to skim card data during a single transaction to create counterfeit cards would have only an old code

Source: 13, 21

Customer-oriented policy that ensures complete liability protection for all card transactions that take place on the Visa system

i. e “You owe nothing in fraudulent transactions”

Identity Theft is a crime where a criminal assumes someone else's identity in order to profit by fraudulent means

Not the same as Credit Card Fraud

48Source: 8

Identity theft is one of the fastest growing crimes in the United States

Identity Theft costs almost $53 billion between business and individual victims for all types of reported identity theft ◦ Business victims experienced a total loss of $47.5

billion or an average of $4,800 per business victim per year

◦ Individual victims account for a total loss of $5 billion and $500 per victim annually

Americans spent 300 million hours resolving issues related to identity theft

A data aggregation company based in Alpharetta, near Atlanta, Georgia

Acts as a private intelligence service to government and industry: combines personal data sourced from multiple public and private databases for sale to the government and the private sector

Maintains more than 17 billion records of individuals and businesses, which it sells to an estimated 100,000 clients, including 7,000 federal, state and local law enforcement agencies

Source: 8

In February 2005 ChoicePoint revealed that sensitive information for at least 114,000 (some sources say 163,000) people had been compromised

The breach occurred earlier in 2004, when criminals posed as customers to obtain data

No direct technology breach occurred, butmedia characterized the incident as if one had

At least 750 (some sources say 5,000) cases of identity theft as a result of the breach

Similar scam perpetrated in 2000 resulted in at least $1 million in fraudulent purchases

53Source: 7, 8, 20

A number of investigations including congress people, the Federal Trade Commission, the US Securities and Exchange Commission and US state attorneys general as well as personal lawsuit

ChoicePoint has agreed to pay $15 million:◦ $ 10 billion fine◦ $ 5 billion as a fund to help the victims of the identity

theft Company must overhaul its security program

and submit to independent audits of security procedures every 2 years for the next 20 years

54Source: 11

In April 2007 a Gartner Analyst told USA Today that "ChoicePoint transformed itself from a poster child of data breaches to a role model for data security and privacy practices“

◦ Some of the preventive steps included abandoning a line of business worth $20 million because of its potential to risk a future data breach

55Source: 7, 16

5-step action plan for securing data and privacy system proposed by ChoicePoint’s CIO:

1. Governance – Chief Privacy Officer reports to a board that governs privacy and public responsibility

2. Clearly define expected behavior and provide tools to simplify compliance for employees

3. Create data breach response policies and procedures

4. Determine the credentials of those you work with and those who work for you

5. Embrace openness
