Description
When directory service data files, especially for directories used for identification, authentication, or authorization, reside on the same logical partition as user-owned files, the directory service data may be more vulnerable to unauthorized access or other availability compromises. Directory service and user-owned data files sharing a partition may be configured with less restrictive permissions in order to allow access to the user data. The directory service may be vulnerable to a Denial of Service attack when user-owned files on a common partition are expanded to an extent preventing the directory service from acquiring more space for directory or audit data.

1. Refer to the AD database, log, and work file information obtained in check V-8316. Note the logical drive (e.g., “C:”) on which the files are located. 2. Determine if the server is currently providing file sharing services to users by typing the following command: Enter “net share” at a command line prompt. 3. Record the logical drive(s) or file system partition for any site-created data shares. (Ignore all system (Windows NETLOGON, SYSVOL, and administrative (ending in $)) shares. User shares that are hidden, ending with $, should not be ignored.) 4. If data files owned by users are located on the same logical partition as the directory server database, log, or work files, then this is a finding.

Ensure the directory server data files are stored on a different logical partition then the files owned by users.
