Explanation

TACACS+ is an AAA (Authentication, Authorization, and Accounting) protocol that centralizes the management of who can access network devices and what they can do. Centralizing access control onto a single server makes it straightforward to audit, review, and modify user rights and permissions across all equipment from one place - directly supporting a user rights and permissions review strategy. This is a key risk mitigation technique: by consolidating access records, administrators can quickly identify excessive privileges or unauthorized accounts. Change management, DLP, and data theft prevention are separate risk domains not directly addressed by a centralized AAA system.
