Explanation
Authentication is the process of verifying who a user claims to be before granting system access - it is the definition of identity verification in access control. Encryption protects data confidentiality but does not verify identity. A firewall controls network traffic based on rules but does not authenticate users. An intrusion detection system (IDS) monitors for suspicious activity after access has occurred. Authentication is step one in the AAA model (Authentication, Authorization, Accounting).
