Internet Security

2 Computers on the Internet are almost constantly bombarded with viruses, other malware and other threats.

3 An from your bank, asking you to change your online password for security reasons, may actually be a fraud, sent by a criminal hoping to access your account. A file attached to an from a friend may be, in reality, a destructive computer virus, sent without your friend’s knowledge.

4 Firewall A firewall is basically the first line of defence for your network. The basic purpose of a firewall is to keep uninvited guests from browsing your network. A firewall acts as the gatekeeper for all incoming and outgoing traffic.

5 Firewall Microsoft Windows XP - comes with a built-in firewall. Unfortunately, it is not enabled by default so you have to know enough to go in and turn it on. ICF only monitors and blocks inbound traffic. That is great for protecting you from external hacking or malicious activity, however it will not protect you from situations where a virus or Trojan on your system attempts to initiate unauthorized or malicious network activity out from your computer.

6 Zone Alarm Monitors both inbound and outbound traffic Blocks hackers from infiltrating your home PC by hiding your computer from unsolicited network traffic. By detecting and preventing intrusions, ZoneAlarm Free Firewall keeps your PC free from viruses that slow down performance, and spyware that steals your personal information, passwords, and financial data.

7 Creating Secure Passwords
