Computer Security, Ethics and Privacy





A security risks is any event or action that results in a loss of data or damage to a computers hardware or software. There are a few different types of security risks when discussing computers.

1. Internet and network attacks. Example: Viruses and worms
2. Unathorized access and use
3. Harware theft. Example: Stolen computer
4. Software theft. Example: Piracy
5. Information theft. Example: Stolen Identity
6. Systen Failure: Example: Lightning striking computer
7. Wireless security. Example: wi-fi tapping

When information travels over a network, it is at a greater risk than if it were local information because there are more ways to intercept the information. A virus is a program that alters the computer and damages it files. It requires human interaction to be spread. A worm copies itself and takes up space on your computer, doesn't require humans to speread it. A Trojan Horse is software that hides behind something that seems hardless, doesn't spread.

How to avoid getting attacks:

1. Use a firewall
2. Keep anti virus software up to date
3. STay alert and watch news
