JUNI-RT-000250 - The Juniper perimeter router must be configured to enforce approved authorizations for controlling the flow of information between interconnected networks in accordance with applicable policy.

Information

Information flow control regulates authorized information to travel within a network and between interconnected networks. Controlling the flow of network traffic is critical so it does not introduce any unacceptable risk to the network infrastructure or data. An example of a flow control restriction is blocking outside traffic claiming to be from within the organization. For most routers, internal information flow control is a product of system design.

NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.

Solution

This requirement is not applicable for the DODIN Backbone.

[edit firewall family inet]
set filter FILTER_INBOUND_TRAFFIC term TCP_ESTABLISHED from tcp-established
set filter FILTER_INBOUND_TRAFFIC term TCP_ESTABLISHED then accept
set filter FILTER_INBOUND_TRAFFIC term ALLOW_BGP from source-address x.1.12.1/32
set filter FILTER_INBOUND_TRAFFIC term ALLOW_BGP from protocol tcp
set filter FILTER_INBOUND_TRAFFIC term ALLOW_BGP from destination-port bgp
set filter FILTER_INBOUND_TRAFFIC term ALLOW_BGP then accept
set filter FILTER_INBOUND_TRAFFIC term ALLOW_PING from protocol icmp
set filter FILTER_INBOUND_TRAFFIC term ALLOW_PING from icmp-type echo-reply
set filter FILTER_INBOUND_TRAFFIC term ALLOW_PING from icmp-type echo-request
set filter FILTER_INBOUND_TRAFFIC term ALLOW_PING then accept
set filter FILTER_INBOUND_TRAFFIC term ALLOW_WWW from destination-address x.12.1.22/32
set filter FILTER_INBOUND_TRAFFIC term ALLOW_WWW from protocol tcp
set filter FILTER_INBOUND_TRAFFIC term ALLOW_WWW from destination-port http
set filter FILTER_INBOUND_TRAFFIC term ALLOW_WWW then accept
set filter FILTER_INBOUND_TRAFFIC term DENY_ALL_OTHER then syslog
set filter FILTER_INBOUND_TRAFFIC term DENY_ALL_OTHER then reject

Step 2: Apply the filter inbound on all applicable interfaces.

[edit interfaces ge-0/0/0 unit 0 family inet]
set filter input FILTER_INBOUND_TRAFFIC
