SharePoint Audit Logging
SharePoint 2007, 2010 and 2013 have a built-in audit logging capability that allows you
to track site collection user and administrative activity.
The Windows SharePoint Services 3.0 and SharePoint Foundation products also have
this audit function but it is not exposed in the interface. Auditing in these “free”
versions of SharePoint is only accessible programmatically such as through
LOGbinder for SharePoint.
End-User Tracking
You can track end-user operations including the viewing of documents, document libraries,
lists and list items. SharePoint can audit document check-in and check-out as well
as updates to list items and documents.
Administrator Tracking
You can also audit important site collection
level administration such as permission changes, role updates, group membership
changes and changes to the audit policy itself. Some administrative changes such
as farm administrator assignments, site collection creation and other farm level
operations are not audited.
