Authentication: This is the process of verifying the identity of a user who is attempting to access a system or resource. Authentication can be achieved through various methods such as passwords, biometrics (e.g., fingerprints or facial recognition), or multi-factor authentication (e.g., combining a password with a security token or a fingerprint scan).
Authorization: Once a user is authenticated, authorization determines what actions they are allowed to perform within the system or resource. Authorization can be managed through access control policies and permissions that define what resources a user can access and what operations they can perform on those resources.
Auditing: This involves monitoring and logging access to sensitive resources to detect and respond to any unauthorized attempts to access them. Auditing is crucial for detecting and mitigating security breaches, as well as maintaining compliance with regulations and policies.
