The Cisco IOS XE router must enforce a minimum 15-character password length.
Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. Password length is one factor of several that helps to determine strength and how long it takes to crack a password. The shorter the password, the lower the number of possible combinations that need to be tested before the password is compromised. Use of more characters in a password helps to exponentially increase the time and/or resources required to compromise the password.
Use the following commands to configure minimum password length: aaa common-criteria policy <Policy Name> min-length 15
Verify that the Cisco IOS XE router enforces a minimum password length of "15" characters. The configuration should look similar to the example below: aaa common-criteria policy <Policy Name> min-length 15 If a minimum password length of "15" characters is not enforced, this is a finding.
