Discussion

Multicast echo requests can be useful for reconnaissance of systems and for denial of service attacks.

Check Content

Determine if response to multicast echo requests is disabled.

# ipadm show-prop -p _respond_to_echo_multicast -co current ipv4
# ipadm show-prop -p _respond_to_echo_multicast -co current ipv6


If the output of all commands is not "0", this is a finding.

Fix Text

The Network Management profile is required.

Disable respond to echo multi-cast for IPv4 and IPv6.

# pfexec ipadm set-prop -p _respond_to_echo_multicast=0 ipv4
# pfexec ipadm set-prop -p _respond_to_echo_multicast=0 ipv6
