This is true as ICMP (Internet Control Message Protocol) is commonly used for network diagnostics, but it can also be exploited by hackers for various attacks such as ping flooding and denial of service (DoS) attacks. By denying all ICMP data, it limits the attack surface and reduces the risk of compromise. However, some ICMP traffic (such as echo requests and replies) may be necessary for network troubleshooting and should be allowed.
