Check: CISR-ND-000118
Cisco IOS XE Release 3 NDM STIG:
CISR-ND-000118
(in versions v1 r5 through v1 r4)
Title
Applications used for nonlocal maintenance sessions must implement cryptographic mechanisms to protect the confidentiality 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 eavesdropping, potentially putting sensitive data (including administrator passwords) at risk of compromise and potentially allowing hijacking of maintenance sessions.
Check Content
Verify that the Cisco IOS XE 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 IOS XE 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
