Configure the router to allow only incoming communications from authorized sources to be routed to authorized destinations.

Check Contents

This requirement is not applicable for the DoDIN Backbone.

Review the router configuration to determine if the router allows only incoming communications from authorized sources to be routed to authorized destinations. The hypothetical example below allows inbound NTP from host x.3.12.33 only to host x.1.22.4.

filter INBOUND_FILTER {
term ALLOW_NTP {
from {
source-address {
x.3.12.33/32;
}
destination-address {
x.1.22.4/32; <<< change to global address
}
protocol udp;
destination-port ntp;
}
}
}

If the router does not restrict incoming communications to allow only authorized sources and destinations, this is a finding.
