Application of AAA security management in classified network

In classified information system, network security is often described as the cornerstone, and network components (such as routers and switches) are central assets. However, security management is usually based on IOS command only, which may cause the loss of network assurance. This article described the application of AAA security management in certain classified information network environment. To evaluate the enhancement the security protection, we compared the meet of standard for protection of state secrets, account security, log security, operation and audit facilitation by a designed prospective, randomized and compared study. The results showed that the AAA group was in accordance with standard for protection of state secrets, meanwhile AAA security management could provide safer account, more traceable log, and less time-consuming operation and audit. Based on the results, we strongly recommended that AAA security management should be widely applied to classified network.
