Computer geeks, help me?

Question

What does this means? I really need to know. But please explain it in simple sentences

1. Logic bombs
2. Salami attacks
3. Worm
4. Trojan horse
5. Brontok

Answer 1

1. Logic Bomb: A logic bomb is a piece of code intentionally inserted into a software system that will set off a malicious function when specified conditions are met. For example, a programmer may hide a piece of code that starts deleting files, should he ever leave the company.

2. Salami Attacks: A salami attack is a series of minor data-security attacks that together results in a larger attack. For example, a fraud activity in a bank where an employee steals a small amount of funds from several accounts, can be considered a salami attack. Crimes involving salami attacks typically are difficult to detect and trace.

3. Worm : A computer worm is a self-replicating computer program. It uses a network to send copies of itself to other systems and it may do so without any user intervention. Unlike a virus, it does not need to attach itself to an existing program. Worms always harm the network (if only by consuming bandwidth), whereas viruses always infect or corrupt files on a targeted computer.

4. In the context of computer software, a Trojan horse is a malicious program that is disguised as or embedded within legitimate software. The term is derived from the classical myth of the Trojan Horse. They may look useful or interesting (or at the very least harmless) to an unsuspecting user, but are actually harmful when executed.

5. Brontok: Brontok is a complex e-mail worm. This particular variant was found at the end of March 2006. The worm spreads as an attachment to e-mail messages. It also disables anti-virus software, creates multiple copies of itself on a local hard disk, and takes efforts to make its removal difficult.

Hope I answered your query....

Answer 2

1. Logic bombs (aka time bombs) delete information when specific conditions are met.
2. Salami attacks are a series of minor attacks, resulting in a major attack.
3. Computer worm is a self-replicating computer program. It does not need user intervention to work.
4. Trojan horse is a malicious virus embedded in a legitimate program. Just think of the Greek myth of the Trojan Horse.
5. Brontok (aka W32.Brontok) was 1st discovered last year in the Philippines and is a mass mailing worm. It also affects Pen Drives.

These definitions were found by doing a simple search on the Internet and mostly from Wikipedia.com and Niser.org
