| Description |
|---|
| 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 DACL that specifies who can access the objects with what permissions. If this policy is enabled, the default DACL is stronger, allowing non-admin users to read shared objects, but not modify shared objects that they did not create. |
| ℹ️ Check |
|---|
| If the following registry value does not exist or is not configured as specified, this is a finding: Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SYSTEM\CurrentControlSet\Control\Session Manager\ Value Name: ProtectionMode Value Type: REG_DWORD Value: 1 |
| ✔️ Fix |

| 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". |
