Protocol defense device with high security

Abstract

The invention discloses a protocol defense device with high security and relates to the technical field of network defense, the system comprises an OCS system, a protocol defense device, a network situation security perception module, an adjustment automation system intrinsic safety IPS system and a transformer substation. The protocol defense device is deployed between an OCS system and a transformer substation in a transparent mode. Longitudinal data issued by the OCS arrives at a transformer substation through the protocol defense device, meanwhile, a longitudinal data copy is copied and sent to the transfer automation system intrinsic safety IPS system, and when a network abnormal behavior occurs, the protocol defense device receives a network safety situation awareness system instruction or a dispatcher is remotely controlled to be switched on and off. According to the protocol defense device with high security, uninterrupted communication link and information damage-free processing are realized, so that malicious control on a transformer substation is prevented, other types of messages can normally pass through, and a system monitoring function is not influenced.

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...
