Fix Recommendation

Configure the Cisco router to implement cryptographic mechanisms to protect the confidentiality of remote maintenance sessions using a FIPS 140-2 approved algorithm as shown in the examples below.

SSH Example

R1(config)#ip ssh server algorithm encryption aes256-ctr aes192-ctr aes128-ctr

Check Contents

Review the Cisco router configuration to verify that it is compliant with this requirement.

SSH Example

ip ssh version 2
ip ssh server algorithm encryption aes256-ctr aes192-ctr aes128-ctr

If the router is not configured to implement cryptographic mechanisms to protect the confidentiality of remote maintenance sessions using a FIPS 140-2 approved algorithm, this is a finding.
