Blocking Pings??

I was at shields up website and ran a basic security test on CIS. It did a pretty good job overall, but one flaw that was mentioned was:

Ping Reply: RECEIVED (FAILED) — Your system REPLIED to our Ping (ICMP Echo) requests, making it visible on the Internet. Most personal firewalls can be configured to block, drop, and ignore such ping requests in order to better hide systems from hackers. This is highly recommended since “Ping” is among the oldest and most common methods used to locate systems prior to further exploitation.

Is there a way to prevent this using CIS (or any other way to prevent this)?

thanks.

Are you behind a router? Then the router is being tested and not your firewall.

I also had that experience (the GRC Shields Up test), that result, and that question about blocking pings. In Stealth mode the firewall passes every part except the ping test. From what I’ve read in the postings here, my impression is that:

  1. COMODO Firewall can’t block/drop pings, and,
  2. It’s not really important, and may, in fact, violate some protocol

Does that agree with your reading of the “problem”?

I used Zonealarm on my previous box, which passed the test, but this one runs Vista, so I’m trying out the COMODO firewall, which seems fine except for this one minor thing.

Thanks

1- Comodo can block pings.

2- The majority of the pings received are completely harmless. I really wouldn’t worry if your router is responding to pings. If someone gets past your router, then they’ll also need to get past Comodo.
