Information security system and method with anti-attack function

Abstract

An information security system with an anti-attack function is provided with a physical hardware detection module, a network connection state detection module, a static network comparison module, an attack information collection module and a simulation operation system. The method comprises the following specific steps: 1, collecting equipment operation data in real time through a hardware detection module, comparing the equipment operation data with an equipment operation database, if no abnormality exists, entering the next step, and otherwise, giving an alarm; 2, detecting the network connection state of each device in real time; 3, comparing with a network static connection database, if the data is consistent, entering the next step, and if the data is inconsistent, abnormal, blockingthe connection and sending an alarm; 4, storing the attack information into an attack information base, collecting the attack information on the Internet regularly, and perfecting the attack information base; and 5, enabling the attack information base to select an attack instruction, attack equipment in the simulation system, formulate a blocking strategy according to an attack process, and update an actual operation system according to the blocking strategy.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to an information security system and method capable of preventing attacks. Background technique [0002] With the continuous development of computer science, information technology, information security, power system and other related fields, the construction of smart grid has introduced new technologies such as cloud computing, big data, mobile Internet, Internet of Things, etc., grid information acquisition methods, New changes will occur in storage forms, transmission channels, and processing methods, and the basic network environment will also undergo corresponding changes. The power system has developed into a complex system with deep integration of information and physics, and its stable operation cannot be separated from the real-time scheduling of its information system. At present, unstable factors such as terrorist threats and military conflicts frequently appea...
