COMPUTER ETHICS
What is a Computer Ethics:
…………..Computer Ethics is a branch of practical philosophy which deals with how computing professionals should make decisions regarding professional and social conduct..
Introduction:
A computer system consists not only of software , hardware, data/information and procedures, but also people (the users of computer system). Because computers systems are the products of human efforts, we cannot trust them anymore than we trust people. People can use computer systems for both good and bad purposes, and they may appreciate them or be suspicious of them when they use them.
…..…….But regardless of how they use them or how they feel
about them, most people realize that computers have changed the way we live.
What are the consequences of the
widespread presence of the computer technology??
.…..The threats to computers and communication
systems…….
Introduction:
Information technology can be disabled by a number of occurrences. It
may be harmed by people, procedural, and software errors; by electromechanical
problems; and by “dirty data”. It may be threatened by natural hazards and by civil
strife and terrorism. Criminal acts perpetrated against computers include theft of hardware, software, time and
services, and information; and crimes of malice and destruction…
….Computers may be harmed by viruses. Computers can also be used as
instruments of crime. Criminals may be employees, outside users, hackers, crackers,
and professional criminals…
Is computer technology creating more problems
than its solving??

Errors and Accidents
…….In general, errors and accidents in computer systems may be classified
as People Errors, Procedural Errors, Software Errors,
Electromechanical Problems, and “Dirty Data” problems….
People Errors
Recall that one part of computer system is the people who manage it or run it…
Procedural Errors
Some spectacular computer failures have occurred because someone didn’t follow procedures..
Software Errors
We are forever hearing about “Software Glitches” or software
bugs. A Software Bug is an error in a program that causes it
to malfunction..
Electromechanical Problems
Absence of Electricity or power failure causing the system
not to work ..
Dirty Data
Is Data that is incomplete, outdated or otherwise inaccurate
that causes errors in the computer system..
Natural and Other Hazards
Natural Hazards
What ever is harmful to property and to people, is harmful to computers and communication system. This certainly includes natural disasters…………Natural Hazards can disable all the electronic systems we take for granted…
Civil Strife and Terrorism
Crimes Against Computers and
Communications
Information-technology Crime can be of two types:
1. Illegal act perpetrated against computers or telecommunications..
2. Use of computers or telecommunications to accomplish an illegal act..
Crimes against information technology include theft….
1. Theft of Hardware2. Theft of Software3. Theft of Time and Services4. Theft of Information5. Theft of Malice and Destruction
Crimes Using Computers and Communications……
Computers and communications or information technology has also been used to solve crimes….……..Just as a car can be used to assist in a crime, so can a computer or communication system..
VIRUSES
Viruses
Viruses are a form of high-tech maliciousness. Computer
Viruses are “Deviant” programs that can cause destruction to
computers that contract them…
They are passed in two ways…….
1. Via an Infected Diskette
2. Via a Network
Some common forms of Viruses…
Boot-sector VirusFile VirusWormLogic BombTrojan HorsePolymorphic VirusVirus Mutation Engines
Antivirus Software
Scans a computer’s hard disk, diskettes, and main memory to
detect viruses, and sometimes, to destroy them…..
Computer Criminals
What kind of people are perpetrating most of the Information Technology???
