Navigate Tips for:
First Steps for Protecting Your Computer Systems
1. Use antivirus software on all servers, desktops and laptops. Check for new virus definitions daily and scan your system weekly.
2. Stay up to date with software and security patches.
3. Use a firewall on every computer (check your software to see if it's built-in) and, as an additional line of defense, install a network firewall.
4. Use a boot password to prevent access when you're away from your computers.
5. Use a virtual private network (VPN) over a wireless network to prevent hackers from intercepting your data.
Guidelines for Good Passwords
1. Change default passwords. (They're easily guessed and often exchanged in hacker chat rooms.)
2. Use upper and lower case letters, numbers and symbols.
3. Try abbreviating a phrase that's memorable only to you (include numbers and symbols).
4. Use passwords that are at least 8 characters long.
5. Change passwords at least every 90 days.
6. Don't share your passwords.
Threats to watch out for.
Be aware of these emerging threats from cyber thieves.
1. Hackers exploiting IM and text messaging to unleash viruses through backdoors in security software.
2. Phishing emails that target a group of people within a company or organization. Often, they appear to come from someone in the HR department.
3. Phishing attacks on cell phones and PDAs.
4. New viruses that spread from phones to PCs through Bluetooth connections and mobile messaging services.
5. Theft of PDA smart phones. Keep an eye on yours.
6. Attacks on voice over IP (VoIP) systems. Criminals are exploiting security holes in this hastily deployed technology.
