Fix Recommendation

Configure the system to not respond to ICMP ECHO_REQUESTs sent to broadcast addresses.
# ndd -set /dev/ip ip_respond_to_echo_broadcast 0
Also add this command to a system startup script.

Check Contents

Determine the type of zone that you are currently securing.
# zonename

If the zone is not the global zone, determine if any interfaces are exclusive to the zone:
# dladm show-link

If the output indicates "insufficient privileges" then this requirement is not applicable.

If the zone is the global zone or the non-global zone has exclusive interfaces verify the system does not respond to ICMP ECHO_REQUESTs set to broadcast addresses.
# ndd /dev/ip ip_respond_to_echo_broadcast

If the result is not 0, this is a finding.
