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. Satisfies: SRG-OS-000069-GPOS-00037,SRG-OS-000070-GPOS-00038

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])(?=.*[a-z])(?=.*[0-9]).*$'\''")])' -

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