Auditing and Configuring Security in a Simulated Enterprise Environment

AAA protocols are critical for strengthening access control in enterprise networks by centralizing identity management and ensuring accountability through activity logging.
The case study involves NetBank Ltd., a fictitious financial services company that has outgrown the limitations of traditional local passwords. The organization seeks to transition toward a centralized AAA solution to mitigate risks such as shared credentials, lack of access traceability, and limited administrative control. Students will configure routers to authenticate against TACACS+ and RADIUS servers, verify redundancy through local accounts, and audit system responses under normal and attack conditions.
