Such examples include a department needing to charge other departments for access tofees or one company providing internal support for another. AAA auditing can track usage (e.g. dial-up access), record the data collectedin a database in the form of logs, and generate reports on the data collected.Although auditing is often thought of as a network management or financial management issue, because it is so closely tied to security, auditing will be discussed hereauditing is discussed briefly here. One security issue that auditing addresses is the creation of a list of users and the times they dial into the network. For example, if an administratorknows that an employee logged into the system in the middle of the night, they can use this information to further investigate the purpose of that log-in.Another reason to implement auditing is to create a list of changes that occur in the network, who makes them, and the exact nature of those changes. This information can be used to assist in troubleshooting if these changes lead to an unintended outcome.Cisco Security ACS acts as a central repository for audit information, essentially keeping track of events that occur in the network. Each session established through Cisco Security ACS can be fully audited and stored on the server. This stored information is useful for administration, security auditing, capacity planning, and network usage billing.Similar to the list of authentication and authorization methods, the list of methods used for auditing defines how the audits are performed and the order in which they are performed.When enabled, the default audit method list is automatically applied to all interfaces, unless a user-defined audit method list is explicitly applied to the interface
