Morning Star Day Qing Han ma firewall gateway anti-virus filtering function detailed

Internet viruses can spread across the globe in a very short period of time, and caused incalculable losses, and Venus Chen company days Qing Han horse firewall unique gateway virus filtering function, through the firewall and gateway virus filtering work together to effectively prevent and kill viruses, so that enterprises can no longer bear the pain of the virus.

Network security is a systematic project, so now the experts suggest: network security needs to consider the whole, many start, through a combination of means to minimize the security risks. The same is true of antivirus. Now the means of anti-virus has become rich, host anti-virus, network Anti-Virus, Gateway Anti-Virus ... A variety of means, each have characteristics, complementary, these means are necessary, who can not replace who, only they do their own duties, in order to better reduce security risks. Gateway Antivirus acts as a "Yiffang, Fumo opens" role, through the network data stream virus scanning, before the virus reached the enterprise network to kill it, can effectively improve the entire network of host virus immunity, but also to avoid the network within the host network virus as a springboard, Propagate the virus to a host outside the network.

Although there are many companies in the market now declare: Their firewall products are integrated security gateway, can achieve firewalls, anti-virus and other security features. However, they also have to admit that in these various security functions, anti-virus function is the most difficult to achieve, the effect is often unsatisfactory. Anti-virus function is the difficulty in many functions of integrated security gateway, because as a gateway-level product, the amount of data itself is very large, in order to ensure that the incoming packets are "clean", you need to open, analyze, check each packet, which is a relatively long process, a packet so, All packets are so easy to drag a firewall device down. What's different is that the day-Qing Han-ma firewall uses a very high performance NP architecture, and also with the help of the star in the IDs technology for many years of accumulation, using its unique "IDs protocol Restore Technology", the application of data flow reorganization, and then the virus features matching, cleverly solved this problem.

Tian Qing Han ma firewall virus library capacity is very large, users in the configuration of virus scanning can be based on the actual needs of the choice: standard virus, covering more than 30000 viruses, in general, choose this virus can effectively filter out most of the common virus, expand the virus library, covering more than 50000 kinds of viruses, Basically includes all known viruses. In order to filter the network virus more effectively, in addition to signature recognition, wide spectrum signature, heuristic scanning technology, and other common detection methods, Tian Qing Han ma firewall also uses a variety of advanced new generation of virus scanning engine technology, clever and accurate algorithm to ensure that in the detection of a large number of viruses, still maintain high speed and accurate detection results, These include:

OLE Detach Technology: Macro scans extract macros from Office files, detect macros based on known macro virus strings, and analyze code behavior in macros to identify macro viruses.
