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.

AAA协议（AAA protocols）通过集中化身份管理与活动日志记录保障责任可追溯性，对强化企业网络的访问控制至关重要。
本案例研究的对象为NetBank有限公司——一家已不再适配传统本地密码局限性的虚拟金融服务企业。该机构正寻求向集中式AAA解决方案转型，以缓解共享凭证、访问可追溯性缺失以及行政管控能力有限等风险。
学员将配置路由器，使其对接TACACS+与RADIUS服务器完成身份验证，通过本地账户验证冗余性，并在正常与攻击场景下审计系统响应。
