Information

The Cisco switch must be configured to implement cryptographic mechanisms to protect the confidentiality of remote maintenance sessions.

GROUP ID: V-220504
RULE ID: SV-220504r1026075

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.

Solution

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)#ssh ciphers aes128-ctr aes256-ctr
