Vulnerability V-224832

The default permissions are adequate when the Security Option "Network access: Let everyone permissions apply to anonymous users" is set to "Disabled" (WN16-SO-000290). Review the permissions for the system drive's root directory (usually C:\). Non-privileged groups such as Users or Authenticated Users must not have greater than "Read & execute" permissions except where noted as defaults. (Individual accounts must not be used to assign permissions.) If permissions are not as restrictive as the default permissions listed below, this is a finding. Viewing in File Explorer: View the Properties of the system drive's root directory. Select the "Security" tab, and the "Advanced" button. Default permissions: C:\ Type - "Allow" for all Inherited from - "None" for all Principal - Access - Applies to SYSTEM - Full control - This folder, subfolders, and files Administrators - Full control - This folder, subfolders, and files Users - Read & execute - This folder, subfolders, and files Users - Create folders/append data - This folder and subfolders Users - Create files/write data - Subfolders only CREATOR OWNER - Full Control - Subfolders and files only Alternately, use icacls: Open "Command Prompt (Admin)".
