For instance to log this event for file permission changes, the \"File System\"\r\nsubcategory must be enabled for success.\r\nNote the following problem is fixed in more recent versions of Windows. Definitely in Windows 8/2012. Not sure\r\nabout Win7 and Win2008R2: This event has been observed as above after deleting an access control entry from\r\nthe file's ACL.  However the event was not logged after simply blocking permission inheritance and copying\r\nexisting ACEs.  Evidently this event is only logged when the effective permissions are changed not inheritance\r\nsettings.\r\nThis event is NOT logged when Active Directory object permissions are changed.\r\nFree Security Log Resources by Randy\r\nFree Security Log Quick Reference Chart\r\nWindows Event Collection: Supercharger Free Edtion\r\nFree Active Directory Change Auditing Solution\r\nFree Course: Security Log Secrets\r\nDescription Fields in 4670\r\nSubject:\r\nThe user and logon session that changed permissions of the object. \r\nSecurity ID: The SID of the account.\r\nhttps://www.ultimatewindowssecurity.com/securitylog/encyclopedia/event.aspx?eventID=4670\r\nPage 1 of 5\n\nAccount Name: The account logon name.\r\nAccount Domain: The domain or - in the case of local accounts - computer name.\r\nLogon ID is a semi-unique (unique between reboots) number that identifies the logon session.
