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

  3. 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.

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

  5. 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.

  8. 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.

  9. 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.
