The summary is worth reading on its own ...

Strategy: Defense in Depth

Layers of protection block different kinds of threats and may provide backup if one layer fails.

Hardware router
  • Using NAT* masks IP address from port scans.
  • Blocks unsolicited incoming communications.
  • Does not protect against most malware, such as Trojan horses, viruses, e-mail worms, and spyware.
Software firewall
  • Included with Windows XP SP2
  • Prevents backdoor apps, Trojan horses, and unwanted applications from sending data from the PC.
  • Protects a laptop on public wired and wireless networks.
  • Can block some malware, but can't remove it.
Antispam software
  • Recommendation: Lavasoft Ad-Aware
  • Blocks deceptive e-mail scams (phishing schemes).
  • Reduces e-mail sorting fatigue, so users are less likely to accidentally activate an e-mail-borne virus in haste.
Antivirus software
  • Protects against known worms, viruses, and Trojan horses but is less effective against new infectors.
  • Systems are still vulnerable to infiltration from adware, spyware, and browser hijackers.
Anti-spyware software
  • Recommendation: Spybot Search & Destroy
  • Protects against adware, browser hijackers, spyware, tracking cookies, and other Internet parasites.

* The Network Address Translation Internet standard allows LANs to use different sets of IP addresses for internal and external traffic.
