This policy setting allows you to audit events generated by attempts to access to Security Accounts Manager (SAM) objects. SAM objects include the following: SAM_ALIAS -- A local group. SAM_GROUP -- A group that is not a local group. SAM_USER - A user account. SAM_DOMAIN - A domain. SAM_SERVER - A computer account. If you configure this policy setting, an audit event is generated when an attempt to access a kernel object is made. Success audits record successful attempts and Failure audits record unsuccessful attempts. If you do not configure this policy setting, no audit event is generated when an attempt to access a kernel object is made. Note: Only the System Access Control List (SACL) for SAM_SERVER can be modified. Volume: High on domain controllers. For information about reducing the amount of events generated in this subcategory, see article 841001 in the Microsoft Knowledge Base (http://go.microsoft.com/fwlink/?LinkId=121698). 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.
