Windows Server 2019 default permissions of global system objects must be strengthened.
An XCCDF Rule
Description
<VulnDiscussion>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 non-administrative users to read shared objects but not to modify shared objects they did not create.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
