What does SACL mean in CYBER & SECURITY

System Access Control List (SACL) is a security feature used with Windows operating systems that provides administrators with the ability to audit user access to system files and folders. It is part of the Discretionary Access Control List (DACL) and enables administrators to record detailed information related to the access history of specific folders or files.

With SACL, administrators can monitor user activities and set up triggers for automated notification when certain events occur. For example, it can be used for auditing purposes, allowing an administrator to track who accessed what and when.

An SACL provides detailed information about a file or folder, such as its owner, date/time stamps for last access/write operations, size/attributes of objects within it, etc. The level of detail provided depends on the type of permissions assigned to the object.

An SACL is generally very secure because it allows only authorized users who have been given permission by an administrator access to sensitive data in a system or network. It also helps protect against unauthorized changes by ensuring that any changes made are recorded in an audit log so they can be reviewed if needed at a later time.

There may be some performance impact due to longer processing times required when auditing is enabled on large numbers of resources which use SACLS for security permissions management. In addition, errors and misconfigurations can occur during setup which could lead to potential disclosure of confidential data from inadequate monitoring or protection measures being applied in error.
