STIGQter: STIG Summary: Juniper EX Series Switches Router Security Technical Implementation Guide Version: 2 Release: 1 Benchmark Date: 24 Jul 2024:

The Juniper router must not be configured to use IPv6 Site Local Unicast addresses.

DISA Rule

SV-254072r844249_rule

Vulnerability Number

V-254072

Group Title

SRG-NET-000512-RTR-000013

Rule Version

Severity

CAT II

CCI(s)

Fix Recommendation

Configure the router using authorized IPv6 addresses.

Delete unauthorized addresses:
delete interfaces <interface name> unit <logical unit number> family inet6 address <unauth address>/<prefix>

Configure authorized addresses:
set interfaces <interface name> unit <logical unit number> family inet6 address <auth address>/<prefix>

Check Contents

Review the router configuration to ensure FEC0::/10 IP addresses are not defined.

Show the interface configuration using "show configuration interfaces" (from operational mode) or "show interfaces" (configuration mode at the top of the hierarchy).

When showing the configuration, piping (|) to match or find (similar to *nix 'grep') will limit the search.

For example, to limit the search to lines that include "FEC0":
(operational mode) show configuration interfaces | match fec0
Returns the lines with 'fec0' but no surrounding context
There should be no returned lines

(operational mode) show configuration interfaces | find fec0
Returns the configuration with the first line containing 'fec0'
Returns context (meaning can scroll up / down in the configuration)
There should be no returned configuration

If IPv6 Site Local Unicast addresses are defined, this is a finding.
