This policy setting allows you to audit events generated by changes to distribution groups such as the following: Distribution group is created, changed, or deleted. Member is added or removed from a distribution group. Distribution group type is changed. If you configure this policy setting, an audit event is generated when an attempt to change a distribution group 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 a distribution group changes. Note: Events in this subcategory are logged only on domain controllers. Volume: Low. Default: No Auditing. 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.
