You can't get hacked if your Windows XP PC can't be found
Remember this mantra: Hackers can't hack what they can't find. Watch today's show to find out how to put yourself under a hacker's radar.
Hackers often look for targets using ping sweeps with a tool such as NMap. When a computer responds to the ping sweep, it's identified and becomes a potential target.
Protect yourself by disallowing pinging, or ICMP requests. When a hacker sends a "are you alive" ping sweep, your computer acts like it's turned off. You're hiding your PC.
