Title

The macOS system must enforce password complexity by requiring that at least one numeric character be used. (Cat II impact)

Discussion

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 determines 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.

Check Content

Verify the macOS system is configured to require at least one numeric character in password complexity with the following command: /usr/sbin/system_profiler SPConfigurationProfileDataType | /usr/bin/grep "requireAlphanumeric" requireAlphanumeric = 1; If the result is not "requireAlphanumeric = 1", this is a finding.

Fix Text

Configure the macOS system to require at least one numeric character in password complexity by installing the "Passcode Policy" configuration profile.
