Drop Incoming ICMPv4 Redirect Messages ICMP redirects are broadcast in order to reshape network traffic. A malicious user could craft fake redirect packets and try to force all network traffic to pass through a network sniffer. If the system is not configured to ignore these packets, it could be suspectible to this kind of attack.


Parameter: enabled/disabled


Technical Mechanism: To check if the system is configured to ignore ICMP redirect messages, run the following command: sysctl net.inet.icmp.drop_redirect If the value is not '1', this is a finding.
