Fix Recommendation

Configure the Nokia router to authenticate NTP sources using authentication that is cryptographically based.

Configure NTP for authentication with MD-5, as shown in the example below:

- configure system time ntp server <NTP server ip address> authentication-key <key id> key <key> type message-digest

Check Contents

Review the Nokia router configuration to determine if the Nokia router authenticates NTP endpoints before establishing a local, remote, or network connection using authentication that is cryptographically based.

Using the command below, verify NTP server "Admin status" and "Oper status" are listed and "Auth Check" is enabled.

- show system ntp detail

NTP Status

Configured : Yes Stratum : 3
Admin Status : up Oper Status : up
Server Enabled : No Server Authenticate : No
Clock Source : 10.1.0.158
Auth Check : Yes
Auth Keychain : test
Auth Errors : 0 Auth Errors Ignored : 0
Auth Key Id Errors : 0 Auth Key Type Errors : 0
Current Date & Time: 2025/11/12 02:19:32 UTC

NOTE: Nokia router is limited to MD-5 for NTP authentication and incurs a permanent finding as it is not FIPS compliant. MD-5 partially reduces the risk but cannot fully mitigate it.

If the Nokia router does not authenticate NTP sources using authentication that is cryptographically based, this is a finding.
