With the rapid development of computer network and information technology, more and more enterprises and governments have established their own Internet information systems. While the network brings high efficiency, the diversified development of network attacks and the explosive growth of bandwidth put forward higher requirements for the processing performance and detection accuracy of network security products. The network guard intrusion detection system (hereinafter referred to as TopSentry products) independently developed by Tianrongxin Company adopts bypass deployment mode, which can detect more than 3,500 kinds of network attacks including overflow attacks, RPC attacks, WEBCGI attacks, denial of service attacks, Trojans, worms and system vulnerabilities in real time. TopSentry products also have the functions of intelligent identification of application protocols, P2P traffic control, network virus detection, malicious website monitoring, intranet monitoring and so on, providing users with a complete three-dimensional network security detection and monitoring.
Fast processing performance is the basic requirement for gateway products, especially for intrusion detection products that process application-layer data. TopSentry's full range of products adopt Tianrongxin's unique patented multi-core processing hardware platform, based on the advanced SmartAMP parallel processing architecture, built-in patented processor dynamic load balancing technology, and combined with the original SecDFA core acceleration algorithm, it realizes high-performance real-time detection of network data streams, making the full detection rate of TopSentry reach 10 Gbps.
Accurately identifying network attacks is the core value of intrusion detection products. TopSentry products use comprehensive technical means such as protocol analysis, pattern matching and abnormal traffic monitoring to judge network intrusion behavior, and can accurately find various network attacks. Tianrongxin Company's Security Attack and Defense Laboratory (hereinafter referred to as TopLabs) is the founder of the national attack detection vulnerability database, as well as the national emergency response support service unit and the national designated postdoctoral workstation. With professional and high-quality technical researchers, through the continuous tracking, research and analysis of newly discovered security vulnerabilities, an attack detection rule base with independent intellectual property rights is formed to ensure that TopSentry products have accurate detection capabilities. The rule base has passed the compatibility certification of CVE, an international authority, and is updated at least once a week.
Stability is the foundation of intrusion detection products. TopSentry products are developed by the firewall R&D team of Tianrongxin Company, and adopt the same multi-core processing hardware platform as the firewall products with independent intellectual property rights of Tianrongxin Company and TOSEC (TOPSEC operating system) system, and inherit the technical experience of gateway products accumulated by Tianrongxin Company 16 years. TopSentry has been deployed in banking, telecommunications, insurance, electric power and other industries. It has high stability and reliability, can identify all kinds of intrusions in various network environments continuously and stably, and provide users with more detailed security protection planning basis.
