ICMP
(Internet Control Message Protocol)
Internet Control Message Protocol (ICMP) is a network-layer protocol used for error reporting and diagnostic functions in IP networks. ICMP is commonly used by tools like ping and traceroute to test connectivity and diagnose network issues.
ICMP messages include error notifications (e.g., destination unreachable) and informational messages (e.g., echo request/reply). While ICMP is essential for network troubleshooting, it can also be exploited in attacks like DDoS (Distributed Denial of Service). Proper network configuration and monitoring are necessary to mitigate such risks.
