1.21 CISC-ND-001210

Information

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

GROUP ID: V-216542RULE ID: SV-216542r961557

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 router to use SSH version 2 as shown in the example below.

RP/0/0/CPU0:R3(config)#ssh server v2
