This policy setting allows you to audit events generated by special logons such as the following : The use of a special logon, which is a logon that has administrator-equivalent privileges and can be used to elevate a process to a higher level. A logon by a member of a Special Group. Special Groups enable you to audit events generated when a member of a certain group has logged on to your network. You can configure a list of group security identifiers (SIDs) in the registry. If any of those SIDs are added to a token during logon and the subcategory is enabled, an event is logged. For more information about this feature, see article 947223 in the Microsoft Knowledge Base (http://go.microsoft.com/fwlink/?LinkId=121697). 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.
