METHOD FOR AUTOMATIC REPLAY ATTACK TEST IN FIELD BUS

摘要

The present invention provides a method for an automatic replay attack test in a field bus. By deploying an attack proxy device on the field bus, an automatic replay attack test without manual intervention is realized. By means of the attack proxy device deployed on the field bus, normal application data units transmitted on the field bus are monitored, and test cases are automatically generated to perform replay attack tests. The efficiency of security tests can be effectively increased, and vulnerability proof-of-concept instances are provided for security personnel. According to the invention, security risks caused by replay attacks on a field bus channel in an automated control system can be reduced, and reliable security assurances are provided for automated control systems, especially for electric power and water conservancy systems, which are key infrastructure systems in the field of national economy. In the present invention, the attack proxy device can be implemented by using a single-chip microcomputer system, without the need of using a high-priced industrial-grade computer. The invention has high device compatibility and universality, and is convenient to popularize.
