how do I STEALTH a PORT?

[ken]

I'm running a system security check online, and all my
ports are stealthed, except my ICMP Ping port is open.
It says since my computer will respond to pings, I will
attract attention from hackers. How can I stealth this
port as well?

For one Ken,

Enable the Internet Connection Firewall (ICF). The default setting is to
not allow IMCP traffic through.
