Network safety detection method and system

Abstract

The invention discloses a network safety detection method and system. The method comprises steps that an intrusion detection system assembly is established, a network card is set by a security probeto be a promiscuous mode, the detection strategy for detecting attack and leak behaviors is received, protocol analysis of captured packets is carried out by the security probe, the captured packets are analyzed into a packet head and a pure load part of each layer such as a link layer, a network layer and a transmission layer, the packet head and the load are carefully examined to detect attack characteristics, and protocol and grammar analysis is further carried out. The method is advantaged in that the structure is scientific and reasonable, the method is safe and convenient to use, attackintrusion outside the network is found, various types of unsafe behaviors within the network are detected, various types of intrusion activities are responded, the entire system has good timeliness, adaptability, security, availability and scalability, and reliable protection is provided for security of an internal host of the LAN.

Description

Technical field [0001] The invention belongs to the technical field of network security, and specifically relates to a network security detection method and system. Background technique [0002] Network security means that the hardware and software of the network system and the data in the system are protected from damage, modification, or leakage due to accidental or malicious reasons. The system operates continuously, reliably and normally, and network services are not interrupted. [0003] However, there are still some unreasonable factors when the existing network security detection methods and systems are in use. When the existing network security detection methods and systems are in use, the protective wall and password authentication are all static defense systems. Some networks are often attacked by hackers. They use online vulnerabilities and defects to modify web pages, illegally enter the host, steal information, and trigger various network cases. In order to detect atta...
