《GB/T 41274-2022可编程控制系统内生安全体系架构》由TC124（全国工业过程测量控制和自动化标准化技术委员会）归口，TC124SC5（全国工业过程测量控制和自动化标准化技术委员会可编程序控制器及系统分会）执行，主管部门为中国机械工业联合会。
Introduction
Interpretation of System Architecture Security Innovation
| Architecture Type | Scope of Application | Intrinsic Security Features |
|---|---|---|
| Embedded PLC Stand-alone System | Small Equipment Control | Dynamic Protection + Resource Access Control |
| Modular Industrial Control System | Medium-sized Device Integration | Network Topology Management + Partition Isolation |
| Distributed Computer Control System | Large-Scale Industry Collaboration | Defense in Depth + Trusted Computing |
Security Technology Evolution Path
According to Article 5.3, the system warning adopts field bus packet analysis technology with a traceback depth of ≥10 layers, and the threat tracking mechanism based on time tunnel can support microsecond-level response under 2G industrial bandwidth.
Application Security Configuration Specifications
| Module Type | Key Life Cycle | Authentication Protocol Configuration |
|---|---|---|
| Engineering Station | ≤90 Days Update | TLS 1.3+AES256-GCM |
| Redundant Controllers | Synchronous Heartbeat Packet Verification | SRTP Deterministic Delay Transmission |
Long-term Protection Implementation Recommendations
- Hierarchical management of human-machine interface: According to the requirements of Section 6.2, the operator station needs to have a three-level dynamic password and biometric composite authentication;
- Application signature verification: SM3 password verification code is implanted during the compilation phase, and the running environment verifies the hash value deviation in real time;
- Intelligent speed limit for abnormal traffic: The IoT AI method is used to achieve threat feature modeling of 1M data packets per second.
