| The use of AAA affords the best methods for controlling user access, authorization levels, and activity logging. By enabling AAA on the IDPS in conjunction with an authentication server, the administrators can easily add, modify, or delete accounts as well as add or remove command authorizations and privilege levels. The use of an authentication server provides the capability to assign network administrators and engineers to tiered groups containing their associated or required privilege level. The IDPS must be configured to restrict management access according to the privilege level the user has been granted. Authorization to add, modify, or delete security policy filters must require the highest privilege level. If system administrators cannot be configured with different security privileges, then need-to-know cannot be enforced. |
