Fix Recommendation

Configure all routing protocol authentications to encrypt the authentication key.

OSPF Example:

[edit protocols ospf area 0.0.0.0]
set interface ge-0/0/0 authentication md5 1 key xxxxxxxxxxxx
set interface ge-0/1/0 authentication md5 1 key xxxxxxxxxxxx
set interface ge-0/2/0 authentication md5 1 key xxxxxxxxxxxx

IS-IS Example:

[edit security authentication-key-chains]
set key-chain ISIS_KEY key 1 options isis-enhanced
set key-chain ISIS_KEY key 2 options isis-enhanced
set key-chain ISIS_KEY key 3 options isis-enhanced
set key-chain ISIS_KEY key 1 start-time 2018-05-01.12:00 algorithm hmac-sha-1 secret xxxxxxxxxxxxx
set key-chain ISIS_KEY key 2 start-time 2018-09-01.12:00 algorithm hmac-sha-1 secret xxxxxxxxxxxxx
set key-chain ISIS_KEY key 3 start-time 2019-01-01.12:00 algorithm hmac-sha-1 secret xxxxxxxxxxxxx

[edit protocols]
set isis level 1 authentication-key-chain ISIS_KEY
set isis interface ge-0/0/0 level 1 hello-authentication-key-chain ISIS_KEY
set isis interface ge-0/0/0 level 2 hello-authentication-key-chain ISIS_KEY

BGP Example:

[edit security authentication-key-chains]
set key-chain BGP_KEY key 1 start-time 2018-05-01.12:00 secret xxxxxxxxxxxxx
set key-chain BGP_KEY key 2 start-time 2018-09-01.12:00 secret xxxxxxxxxxxxx
set key-chain BGP_KEY key 3 start-time 2019-01-01.12:00 secret xxxxxxxxxxxxx

[edit protocols bgp group AS_5]
set neighbor 11.1.25.5 authentication-algorithm hmac-sha-1-96
set neighbor 11.1.25.5 authentication-key-chain BGP_KEY
set neighbor 11.1.1.1 authentication-algorithm hmac-sha-1-96
set neighbor 11.1.1.1 authentication-key-chain BGP_KEY

Review the router configuration. For every routing protocol that affects the routing or forwarding tables, verify that neighbor router authentication is encrypting the authentication key as shown in the examples below.

OSPF Example:

protocols {
…
…
…
ospf {
area 0.0.0.0 {
interface ge-0/0/0 {
authentication {
md5 1 key "$8$NHVb2mPQ3nCYg/t"; ## SECRET-DATA
}
}
interface ge-0/1/0 {
authentication {
md5 1 key "$8$Lgb7NbHkPTQnVwF/"; ## SECRET-DATA
}
}
interface lo0.0;
interface ge-0/2/0 {
authentication {
md5 1 key "$8$7DdVY.mTF39s26A"; ## SECRET-DATA
}
}
}
}
}

authentication-key-chains {
key-chain ISIS_KEY {
key 1 {
secret "$8$W8oXxdji.f5F-VQn"; ## SECRET-DATA

If the routing protocol is not encrypting the authentication key, this is a finding.
