Check: CISR-ND-000117
Cisco ISR 4000 Series NDM STIG:
CISR-ND-000117
(in version v1 r1)
Title
Applications used for nonlocal maintenance sessions must implement cryptographic mechanisms to protect the integrity of nonlocal maintenance and diagnostic communications. (Cat II impact)
Discussion
This requires the use of secure protocols instead of their unsecured counterparts, such as SSH instead of telnet, SCP instead of FTP, and HTTPS instead of HTTP. If unsecured protocols (lacking cryptographic mechanisms) are used for sessions, the contents of those sessions will be susceptible to manipulation, potentially allowing alteration and hijacking of maintenance sessions.
Check Content
Verify that the Cisco ISR 4000 Series router is using SSHv2 for remote access. The configuration should look like the example below: ip ssh version 2 ! line vty 0 98 transport input ssh If secure applications are not being used, this is a finding.
Fix Text
Configure the Cisco ISR 4000 Series router to use SSHv2 for remote access. The configuration should look like the example below: ip ssh version 2 ! line vty 0 98 transport input ssh
