A strong authentication policy should enforcepassword length(e.g., minimum of 12-16 characters) and complexity(mix of uppercase, lowercase, numbers, and symbols). These measures significantlyreduce the risk of brute-force attacks. * Least privilege (C)relates to access control, not authentication policies. * Something you have (D)andbiometrics (F)pertain to multi-factor authentication (MFA) but are not password policy requirements.
