The Dell OS10 Switch 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 Dell OS10 Switch configuration to verify that it enforces the limit of three consecutive invalid logon attempts and a 15-minute lockout period as shown in the example below:

password-attributes lockout-period 15

Note: Since the max-retry value of three is the default value, it will not be displayed when viewing the configuration. So, if the password-attributes max-retry value is not displayed then it is set to three attempts.

If the Dell OS10 Switch is not configured to enforce the limit of three consecutive invalid logon attempts and a 15-minute lockout period, this is a finding.

Configure the Dell OS10 Switch to enforce the limit of three consecutive invalid logon attempts and a 15-minute lockout as shown in the example below:

OS10(config)# password-attributes max-retry 3 lockout-period 15
