Details
Check Text (C-220480r960840_chk)
Review the Cisco switch configuration to verify that it enforces the limit of three consecutive invalid logon attempts as shown in the example below:
ssh login-attempts 3
If the Cisco switch is not configured to enforce the limit of three consecutive invalid logon attempts, this is a finding.
NOTE: The NX-OS switch does not lock out the account, it disconnects the session. The AAA server will lock out the user account on three failed attempts.
Fix Text (F-22184r802431_fix)
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
