System objects: Strengthen default permissions of internal system objects (e.g. Symbolic Links)ID: oval:org.secpod.oval:def:40256 | Date: (C)2017-04-25 (M)2023-07-04 |

This policy setting determines the strength of the default discretionary access control list (DACL) for objects. The setting helps secure objects that can be located and shared among processes and its default configuration strengthens the DACL, because it allows users who are not administrators to read shared objects but does not allow them to modify any that they did not create.
Vulnerability:
This setting determines the strength of the default DACL for objects. Windows Server 2003 maintains a global list of shared computer resources so that objects can be located and shared among processes. Each type of object is created with a default DACL that specifies who can access the objects and with what permissions. If you enable this setting, the default DACL is strengthened because non-administrator users are allowed to read shared objects but not modify shared objects that they did not create.
Counter Measure:
Configure the System objects: Strengthen default permissions of global system objects (for example, Symbolic Links) setting to Enabled.
Potential Impact:
None. This is the default configuration.
Fix:
(1) GPO: Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\System objects: Strengthen default permissions of internal system objects (e.g. Symbolic Links)
(2) REG: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager!ProtectionMode
