Security: System default permissions of global system objects must be strengthened

5e582017-d8f1-44dd-8d33-24a7d8ef496e

Windows systems maintain a global list of shared system resources such as DOS device names, mutexes, and semaphores. Each type of object is created with a default Discretionary Access Control List (DACL) that specifies who can access the objects with what permissions. When this policy is enabled, the default DACL is stronger, allowing nonadministrative users to read shared objects but not to modify shared objects they did not create.

Remediation

To fix this configure the policy value for
Computer Configuration
|_ Windows Settings
|_ Security Settings
|_ Local Policies
|_ Security Options
|_ System objects: Strengthen default permissions of internal system objects (e.g., Symbolic Links) to "Enabled".
