Vulnerability Discussion

The macOS be configured to require at least one lowercase character and
one uppercase character be used when a password is created.

This rule enforces password complexity by requiring users to set passwords that are less vulnerable to
malicious users.

Note: The guidance for password-based authentication in NIST 800-53 (Rev 5) and NIST 800-63B state that
complexity rules should be organizationally defined. The values defined are based on common complexity
values, but an organization may define its own password complexity rules.

Note: The configuration profile generated must be installed from an MDM server.

Check

Configure the macOS system to require at least one lowercase character
and one uppercase character in password complexity by installing the
"com.apple.mobiledevice.passwordpolicy" configuration profile.

Fix

Verify the macOS system is configured to require passwords contain a minimum of one
lowercase character and one uppercase character with the following command:

/usr/bin/pwpolicy -getaccountpolicies 2> /dev/null | /usr/bin/tail +2 | /usr/bin/xmllint --xpath
'boolean(//*[contains(text(),"policyAttributePassword matches '\''.*[A-Z]{1,}[a-z]{1,}.*'\''")])' -

If the result is not "true", this is a finding.
