This policy setting allows you to audit events generated by the closing of a logon session. These events occur on the computer that was accessed. For an interactive logoff the security audit event is generated on the computer that the user account logged on to. If you configure this policy setting, an audit event is generated when a logon session is closed. Success audits record successful attempts to close sessions and Failure audits record unsuccessful attempts to close sessions. If you do not configure this policy setting, no audit event is generated when a logon session is closed. Volume: Low. Default: Success. Counter Measure: Enable Audit policy settings that support the organizational security policy for all the computers in your organization. Identify the components that you need for an audit policy that enables your organization to hold users accountable for their actions while using organizational resources and enables IT departments to detect unauthorized activity efficiently and then track those events in log files. Potential Impact: If no audit settings are configured, or if audit settings are too lax on the computers in your organization, security incidents might not be detected or not enough evidence will be available for network forensic analysis after security incidents occur. However, if audit settings are too severe, critically important entries in the Security log may be obscured by all of the meaningless entries and computer performance and the available amount of data storage may be seriously affected. Companies that operate in certain regulated industries may have legal obligations to log certain events or activities.
