The 3 A's of cybersecurity stand for:
Authentication verifies the identity of a user trying to access a system. This is typically done through passwords, multi-factor authentication, or biometrics like fingerprints.
Authorization determines what level of access a verified user has. For instance, a user might be authenticated to access a system, but only authorized to view specific files, not edit them.
Access control enforces the limitations set by authorization. This might involve firewalls, permissions settings, or other tools that restrict access based on user privileges.
