The Cisco SNA appliance must be configured to enforce the limit of three consecutive invalid logon attempts, after which time it must block any login attempt for 15 minutes.

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

Review the Cisco SNA appliance configuration to verify it enforces the limit of three consecutive invalid logon attempts.

Navigate to Cisco SNA Dashboard >> Configure >> Central Management >> Inventory >> Actions... >> Edit Appliance Configuration >> General >> Session Settings >> Number of Unsuccessful Attempts and Duration of Lockout.

If the Cisco SNA appliance is not configured to enforce the limit of three consecutive invalid logon attempts, this is a finding.

Configure the Cisco SNA appliance to enforce the limit of three consecutive invalid logon attempts during a 15-minute time period.

Navigate to Cisco SNA Dashboard >> Configure >> Central Management >> Inventory >> Actions... >> Edit Appliance Configuration >> General >> Session Settings.

Input a number for "Number of Unsuccessful Attempts and Duration of Lockout".

Apply the configuration.
