Don't Send ICMPv4 Redirect Messages
ICMP redirects are broadcast in order to reshape network traffic. A malicious user could use the system to send fake redirect packets and try to force all network traffic to pass through a network sniffer. Disabling ICMP redirect broadcasts mitigates this risk.
To check if the system is configured to send ICMP redirects, run the following command:
sysctl net.inet.ip.redirect net.inet6.ip6.redirect
If the values are not set to '0', this is a finding.
