AOS must enforce password complexity by requiring that at least one lowercase character be used.

Use of a complex password helps to increase the time and resources required to compromise the password. Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks.

Password complexity is one factor of several that determine how long it takes to crack a password. The more complex the password, the greater the number of possible combinations that need to be tested before the password is compromised.

Multifactor authentication (MFA) is required for all administrative and user accounts on network devices, except for an account of last resort and (where applicable) a root account. Passwords should only be used when MFA using public key infrastructure (PKI) is not available and for the account of last resort and root account.

Verify the AOS configuration with the following command: show aaa password-policy mgmt

If "Minimum number of Lower Case characters" is not set to "1 characters", this is a finding.

Configure AOS with the following commands: configure terminal aaa password-policy mgmt password-min-lowercase-characters 1 exit write memory
