DENY Statement

The DENY statement explicitly denies permissions to a user or role, overriding any permissions that have been granted. It is used to enforce stricter access control.

Example: Denying DELETE Permission

DENY DELETE ON FreedomFighters TO 'user123';

Output:

User user123 is explicitly denied permission to delete records from the FreedomFighters table.

Do's and Don'ts

Do's

  • Use DENY to explicitly prevent access to sensitive operations.
  • Review DENY statements carefully to ensure they are applied correctly.
  • Document the use of DENY to track intentional restrictions.

Don'ts

  • Don't use DENY unnecessarily, as it may complicate permission management.
  • Don't assume DENY works the same as REVOKE; it explicitly overrides granted permissions.
  • Don't forget to communicate denied permissions to the affected users or roles.
