Trend technology Gateway defense into cloud security technology

With the rapid development of Internet, information security issues are facing a new challenge.　　Tens of thousands of malicious addresses and strangling Trojan virus, the serious threat to the power system security, stability and high quality operation, affecting the "digital power system" of the implementation process. Recently, trend technology has successfully used the unique cloud security technology to effectively curb virus outbreaks worldwide.　　In the long-term exploration of the power industry's network security management needs on the basis of trend technology will be the cloud security products in the Web Security Gateway (IWSA) technology is constantly updated, many of the power companies due to network access characteristics and security level of the climb, have deployed IWSA. The southern grid, for example, has more than 15 subsidiaries, multiple functional departments and more than 300,000 employees across the company. Such a large user community, in the short term through the client deployment scheme to improve the overall network security, obviously there is a very large difficulty.　　After careful research, the Southern power grid finally decided to use security gateways or malicious code filtering equipment at the unified Internet outlets to achieve security protection, so that the same level of security policy adjustment and centralized management. At the same time, the southern Grid network security Administrator also considered the traditional anti-virus gateway products used in the virus interception technology, if the use of virus-library contrast technology, the same, ineffective. If the virus code is simply loaded on a separate hardware for virus filtering, anti-virus effect can not be decided first, the network processing performance alone to see, in the future day-to-day applications will not be able to get rid of "slow" entanglement. Therefore, the southern grid administrators believe that to really play the gateway interception, the effect of airborne anti-virus, the deployment of anti-virus gateway must have a different than the virus database interception technology. and "Cloud computing Security" technology, has become the southern power grid to solve intranet access to Internet security is the choice.　　This is because the IWSA can put 70% of the threat characteristics of the cloud, so that the IWSA and other threat defense devices to reduce the core memory footprint of 70%, greatly releasing the very tight system resources and bandwidth consumption. Southern power grid and other power enterprises in the deployment of IWSA after the virus active interception, which includes the client in the process of access to the Internet virus, Trojan, spyware, phishing and other malicious programs, so as to provide end users with a safe and stable business use environment. But in the product function aspect, IWSA because integrates the trend technology unique cloud security technology, as well as the innovative web Prestige technology (WRT), in fully solves the performance bottleneck premise, the function integration also fully satisfies "a little more uses" the benefit.　　This includes filtering, classifying various Web pages and automatically blocking malicious URLs, as well as adding Chinese virus codes in the Mail virus scanning (SMTP/POP3) and anti-spam intelligence analysis engines, making it more effective for domestic enterprise users to guard against the threat of local popularity.
