Numeric Character in Passwords 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.

To check if the password policy is configured to require that at least one numeric character be used, run the following command: sudo pwpolicy getpolicy | tr ' ' ' ' | grep requiresNumeric If the result is not 'requiresNumeric=1', and password policy is not controlled by a directory server, this is a finding.
