The AAA of cybersecurity refers to Authentication, Authorization, and Accounting. Authentication verifies the identity of users, ensuring they are who they claim to be. Authorization determines what users are allowed to do, granting or restricting access to resources based on their identity. Accounting keeps logs of user activities, tracking what users do and when, which is crucial for auditing and analyzing potential security breaches. This trio forms the backbone of effective cybersecurity practices.
