Run the Computer Management Applet. Expand the “System Tools” object in the Tree window. Expand the “Shared Folders” object. Select the “Shares” object. Right click any user-created shares (ignore “Netlogon”, “Sysvol” and administrative shares; the system will prompt you if Properties are selected for administrative shares). Select Properties. Select the Share Permissions tab. If user-created file shares have not been reconfigured to remove ACL permissions from the “Everyone group”, then this is a finding. Note: On Application Servers, if regular users have write or delete permissions to shares containing application binary files (i.e. .exe, .dll, .cmd, etc.) this is a finding. Documentable: If shares created by applications require the "Everyone" group, this should be documented with the IAO.
