Multilevel security system.
| Classification | Class I | Class II | Class III |
| Sensitivity | High | Moderate | Low |
| Level of security | High | Moderate | Base |
| Access control | | | | Operation and authentication | | | | Read | Three-factor authentication (e.g., password, security token, and biometric identifier) | Two-factor authentication (e.g., password and security token) | Single factor authentication (e.g., password or personal identification number) | Write | Three-factor authentication + signature + OTP | Two-factor authentication + signature | Single factor authentication + signature |
| Encryption security | | | | | Segment | Normal data | Critical data, mapping data | The entire data | The entire data | Algorithm | Simple encryption (e.g., symmetric substitution algorithm) | Industry standard encryption (e.g., AES, RC4 algorithm) | Industry standard encryption (e.g., blowfish algorithm) | Simple encryption (e.g., symmetric substitution algorithm) |
