Fix Recommendation

Configure the system to not respond to IPv6 multicast ICMP echo-requests.

Procedure:
# ndd -set /dev/ip ip6_respond_to_echo_multicast 0

This command must also be added 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 determine if the system is configured to ignore IPv6 multicast ICMP echo-requests.

Procedure:
# ndd -get /dev/ip ip6_respond_to_echo_multicast

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