Cyber Security By: Pratik Gandhi

What is Cyber Security Cyber Security is the protection of information by preventing, detecting, and responding to attacks made through a computer.

Types of Problems Code Based- Viruses- A type of code that requires you to perform an action. For example, opening an email attachment . Trojans- A program that pretends to do one thing but does something else behind the scenes. Worms- Are similar to viruses but are self-replicating.

Hackers Hackers are the people who write the code for viruses, trojans, and worms. They exploit weaknesses in programs for their own personal gain.

Spyware Generally, spyware is also called “Ad-ware”. It is used by the advertising industry. Spyware can send you pop-up ads, redirect you to websites, monitor what websites you visit, or track what keys you type.

How does a Virus get on to a Computer In most cases a Virus or similar infects a computer through the user opening an email attachment. Other ways they may get on to your computer is by clicking on a pop up window or through downloaded software.

Protection Against Attacks Anti-Virus- Programs that scan your computer for patterns of know viruses. Anti-Spyware- Similar to Anti-Virus programs Anti-Spyware is used to detect spyware (cookies, etc.).

Firewalls Firewalls shield a computer from malicious or unnecessary internet traffic, as they block data from certain locations. There are two types: hardware and software. Hardware Firewalls- Are actual physical devices that are positioned between a computer and a router. Software Firewalls- Do the same thing as a hardware based firewall.

Email Security is a big problem with email. To protect yourself you should: Use a password that has upper-case and lower-case letters, numbers, and special characters. Use an Anti-Virus program to scan attachments. Don’t open chain letters or spam.
