What AAA means
AAA (Authentication, Authorization, and Accounting) defines how users are identified, granted permissions, and monitored across IT systems. Authentication verifies identity, authorization enforces access rights, and accounting records activities for auditing. MSPs apply AAA principles in firewalls, VPNs, and Active Directory environments to enhance security and compliance. Learn more: https://en.wikipedia.org/wiki/AAA_(computer_security)
