I was using GRC’s “Shields Up” Shields UP!! — System Error to check vulnerabilities on my computer and all passed except the following.
“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.”
How can I configure Comodo Firewall to block ping requests?
