Security level
The IBM® i platform offers five levels of security. You can choose which level of security you want the system to enforce by setting the security level (QSECURITY) system value.
- Level 10:
- Level 10 is no longer supported.
- Level 20:
- The system requires a user ID and password for sign-on. All users are given access to all objects.
- Level 30:
- The system requires a user ID and password for sign-on. The security of resources is enforced.
- Level 40:
- The system requires a user ID and password for sign-on. The security of resources is enforced. Additional integrity protection features are also enforced.
- Level 50:
- The system requires a user ID and password for sign-on. The security of resources is enforced. Level 40 integrity protection and enhanced integrity protection are enforced. Security level 50 is intended for IBM i platforms with high security requirements, and it is designed to meet Common Criteria (CC) security requirements.
