Study Notes
NTFS Permissions Rules
- Deny Overrides Allow: If a user is a member of two groups, one allowing a permission and the other denying it, the user is denied that permission.
- Ownership: Administrators can take ownership of an object, and the owner of any object can assign permissions.
- Object Permissions on Copy/Move: When an object is copied or moved within the same NTFS volume, it retains its original permissions. However, if moved to a different volume, it inherits the new volume's permissions.
- FAT32: FAT32 file systems do not support permissions or security.
ICACLS
- ICACLS grants permissions: The command
ICACLS C:\NAT\ROOMS\HEROES-ONLY\GRANT SUPERHEROES:(CI)F /Tgives theSUPERHEROESgroup full control (F) to theHEROES_ONLYfolder and all subfolders (/T). - ICACLS denies permissions: The command
ICACLS C:\NAT\ROOMS\HEROES_ONLY\SECRET.TXT /DENY JOKER:(F)denies the userJOKERfull control (F) to the fileSECRET.TXT. - ICACLS backs up ACLs: The command
ICACLS C:\NAT\ROOMS\ /SAVE C:\NAT\ACL_BACKUP.TXT /Tbacks up the Access Control List (ACL) forC:\NAT\ROOMSand all subdirectories into the fileC:\NAT\ACL_BACKUP.TXT. - ICACLS manipulates directory inheritance: The command
ICACLS C:\NAT\ROOMS\215 /DISABLERINHERIT /REMOVE SYSTEM /REMOVE USERSdisables inheritance of permissions for the folderC:\NAT\ROOMS\215and removes permissions for theSYSTEMandUSERSgroups. - ICACLS restores ACLs: The command
ICACLS C:\NAT\ROOMS\215 /RESTORE C:\NAT\ACL_BACKUP.TXTrestores the ACL for the folderC:\NAT\ROOMS\215from the backup fileC:\NAT\ACL_BACKUP.TXT.
NTFS Sharing
- Share and NTFS Permissions: Accessing a folder or file locally uses NTFS permissions. Remotely accessing a shared folder applies both share and NTFS rules.
- UNC Path: When accessing a local share using a UNC path (e.g., \ComputerName\Share), Windows treats it as a remote access and thus applies both share and NTFS rules.
- Share Permissions: Using NTFS permissions to control access is important. It can be combined with share permissions to manage file access from both local and remote users.
