Abstract

The invention discloses a protocol defense device with strong security, which relates to the technical field of network defense, and includes an OCS system, a protocol defense device, a network situation security perception module, an intrinsically safe IPS system of an adjustment automation system, and a substation. The protocol defense device It is deployed between the OCS system and the substation in a transparent mode. The vertical data sent by the OCS system reaches the substation through the protocol defense device, and at the same time, a copy of the vertical data is copied and sent to the intrinsically safe IPS system of the mobilization automation system. When abnormal network behavior occurs , the protocol defense device receives the command of the network security situational awareness system or the dispatcher throws and withdraws via remote control. This highly secure protocol defense device realizes uninterrupted communication links and non-damage processing of information, thus realizing the prevention of malicious control of substations, and at the same time enabling other types of messages to pass normally without affecting the system monitoring function.

Description

technical field [0001] The invention relates to the technical field of network defense, in particular to a protocol defense device with strong security. Background technique [0002] As the current computer network evolves towards a larger scale and higher complexity, attacks against computers and network systems are also developing in a distributed and automated direction. Various technologies to solve network security problems have emerged one after another, such as firewalls, intrusion detection technology, intrusion prevention technology, trusted computing technology, and vulnerability scanning. Collection, processing and analysis are lacking in comprehensive protection of the overall network security situation. Network security situational awareness technology is the combination and enhancement of multiple security technologies based on these technologies. It relies on security equipment, network equipment, and software systems, and uses the security status and securit...
