Security Systems Software and Basics

Anti-Virus Software:
Install virus protection software. That means three things: having it on your computer in the first place, checking daily for new virus signature updates, and then actually scanning all the files on your computer periodically. Update your anti-virus software daily or weekly and schedule a regular scan. Make sure all family members know what to do if the home computer becomes infected.

Install Firewall Software:
Firewalls act as a gatekeepers between your computer or network and the Internet. They are essential for those who keep their computers online through the popular DSL and cable modem connections, but they are also valuable for those who still dial in. Protect your computer from Internet intruders. Use firewalls. Firewalls are usually software product but can also be hardware solutions.
Passwords:
Choose passwords or Personal Identification Numbers (PINs) that are difficult for others to guess. Use both letters and numbers and a combination of lower- and upper-case letters if the passwords are case-sensitive. Use a different password for each of your Internet accounts.
Passwords should not be names, or words (from any language). Hackers who try to obtain passwords for accounts that don't belong to them (called crackers) use large dictionaries filled with these kinds of passwords. In order to protect yourself against these people, simply don't use common words!
Change these passwords frequently. Don't keep your password where someone can see it. If it can possibly be avoided, don't write it down at all. There are ways to create passwords that are both secure and easy to remember. Remember that your password unlocks your online identity. Don't leave yourself logged in when your machine is unattended. Everything that is done with your account can and will be attributed to you. It's best that you keep your password somewhat esoteric. Do not use the same password for different systems.

Backups:
Back up your computer data on disks or CDs regularly. Retain the only copies of those files on removable media and store the media in a safe place. Use accessories such as rewriteable CD drives and zip disks for copies of your important files - they're easy to use and relatively cheap.
Alert:
Be alert for fraudulent (sometimes called "phishing") emails. They may appear to come from a reputable business or a trusted friend but are actually designed to trick you into downloading a virus to your computer or directing you to a Web site to disclose sensitive or personal information. An ounce of prevention is worth a pound of cure, educate all system users to be alert for phishing scams.
Practice Safe Computing:
Protect shared files and folders. Set the permissions on the share to "read-only." This means that no one will be able to copy, delete, modify, or rename your files. Set-up login accounts and file permissions, so only authorised users can access the system. Unix and Windows NT/2000 have these security functions built in. If you run Windows 95/98/Me, you can buy products to provide this protection.
Configure the access restrictions to individual files or folders, so other users can only access the files you want them to. Understand and use the security features provided by your PC software, such as those included in many operating systems, browsers and word processing systems. The safest option is to set your computer to ignore Java and ActiveX programming languages. Otherwise set your browser to ask you each time it is about to run Java and ActiveX code.
Depending on what you know about the site, you will at least have the choice to run it, or not. If information privacy is imperative you should also consider using a file- or disk-encryption system on the sensitive files.
