Remarks

The following list describes the features for which WebAuthenticationFailureAuditEvent events are raised by default by ASP.NET.

Note

By default ASP.NET is configured to log audit failure conditions only, as logging success conditions can severely strain system resources. You can always configure the system to log the success conditions.

  • Forms Authentication. While success audits include the user name that was authenticated; failure audits do not include the user name, since they typically result from a ticket that failed decryption or validation. Both contain the client IP address. The related event audit code is AuditFormsAuthenticationFailure.

  • Membership. Both success and failure audits contain the username that was attempted. Neither form of audit will contain the password that was attempted, because that would risk persisting a valid password in the log. The related event audit code is AuditMembershipAuthenticationFailure.

When a WebAuthenticationFailureAuditEvent is raised, by default it updates the Audit Authentication Failure Events Raised performance counter. To view this performance counter in System Monitor (PerfMon), in the Add Counters window select ASP.NET in the Performance object drop-down list, select the Authentication Failure Events Raised performance counter, and click the Add button. For more information, see Using the System Monitor (PerfMon) with ASP.NET Applications on MSDN.

Note

In most cases you will be able to use the ASP.NET health-monitoring types as implemented, and you will control the health-monitoring system by specifying values in the healthMonitoring configuration section. You can also derive from the health-monitoring types to create your own custom events and providers. For an example of deriving from the WebAuthenticationFailureAuditEvent class, see the example provided in this topic.
