The Cisco Secure ACS rules-based policy model supports the application of different authorization rules under different conditions, and thus policy is contextual and not limited to authorization determined by single group membership. Integration capabilities allow information in external databases to be directly referenced in access policy rules, and attributes can be used both in policy conditions and authorization rules.Cisco Secure ACS features centralized collection and reporting for activity and system health information for full manageability of distributed deployments. It supports proactive operations like monitoring and diagnostics and reactive operations like reporting and troubleshooting. Advanced features include a deploymentwide session monitor, threshold-based notifications, entitlement reports, and diagnostic tools.
