Information

The Cisco switch must be configured to enforce the limit of three consecutive invalid logon attempts, after which time it must disconnect the session.

GROUP ID: V-220480
RULE ID: SV-220480r960840

By limiting the number of failed logon attempts, the risk of unauthorized system access via user password guessing, otherwise known as brute-forcing, is reduced.

Solution

Configure the Cisco switch to enforce the limit of three consecutive invalid logon attempts as shown in the example below:

SW2(config)# ssh login-attempts 3
