Review the router configuration to verify it is using a NIST-validated FIPS 140-2 message authentication code algorithm to authenticate routing protocol messages.

IS-IS Example:

security {

…

}
authentication-key-chains {
key-chain ISIS_KEY {
key 1 {
secret "$8$W8oXxdji.f5F-VQn"; ## SECRET-DATA
start-time "2018-5-1.12:00:00 +0000";
algorithm hmac-sha-1;

}
key 2 {

}
key 3 {

start-time "2019-1-1.12:00:00 +0000";
algorithm hmac-sha-1;
options isis-enhanced;
}
}
}
}

OSPF Example:

IPsec authentication must be used to authenticate OSPF messages with a FIPS 140-2 message authentication code algorithm.

Step 1: Verify the authentication algorithm in the IPsec security association as shown in the example below.

security {
…
…
…
ipsec {
security-association IPSEC-SA1 {
mode transport;
manual {
direction bidirectional {
protocol ah;
spi 256;
authentication {
algorithm hmac-sha1-96;
key ascii-text "$8$u6M6OEcrevL7-YaZUjHmF39B1hP5CuBRle"; ## SECRET-DATA
}
}
}
}
}

Step 2: Verify that an IPsec security association has been configured on the interfaces as shown in the following example:

protocols {
…
…
…
ospf {
area 0.0.0.0 {
interface ge-0/0/0 {
ipsec-sa IPSEC-SA1;
}
interface ge-0/1/0 {
ipsec-sa IPSEC-SA1;
}
interface lo0.0;
interface ge-0/2/0 {
ipsec-sa IPSEC-SA1;
}
}
}
ospf3 {
area 0.0.0.0 {
interface ge-1/2/0 {
ipsec-sa IPSEC-SA1;
}
}
}
}

If a NIST-validated FIPS 140-2 message authentication code algorithm is not being used to authenticate routing protocol messages, this is a finding.

Note: Juniper does not support FIPS 140-2 message authentication code algorithm for RIP.

The Juniper router must be configured to authenticate all routing protocol messages using NIST-validated FIPS 140-2 message authentication code algorithm.
