Kaspersky Cloud Security upgrades start using file Reputation technology

In recent years, with the development of information technology and Internet, all kinds of malicious programs such as viruses, trojans and worms show explosive growth, and the defense response system of traditional security software relying on malicious object database can not adapt to the fast changing network environment. The emergence of "cloud computing" technology has created an opportunity to solve this problem, so many security software vendors are moving the database to the cloud (server side) storage and sharing, to improve the accuracy of analysis and judgment. But this way still does not give full play to "cloud computing" advantage, because the database transfer to the "cloud", still need to spend a certain amount of time on the Unknown program analysis and judgment, the more users feedback data, the cloud computing processing capacity requirements higher.

Kaspersky in the use of "cloud computing" technology used a completely different ideas, and not the analysis of the responsibility of the assessment of all to the cloud server to complete, but more to adopt the user's feedback. In the face of an unknown program, Kaspersky security forces in addition to the cloud is located in the "Kaspersky Security Network" to send basic information, but also submit users of the program to trust the degree of judgment results. The Kaspersky Security Network collects and collates the information and then feeds it back to every user who uses the program so that the user can get a statistical result of a global billion sample that will help the user accurately determine what the unknown program is capable of doing.

When a user runs an unknown program in the "secure desktop" of Kaspersky security Forces, it pops up the "Application Control" prompt window, detailing the earliest time that the change was available in Kaspersky's security Network, the number of users who used the program, and the percentage of users who trusted the program. Finally, the user is prompted to judge the degree of trust in the program.

Because the Kaspersky secure network technology involves some of the data and information on the user's computer, the installation process will explicitly indicate what data the user will use. Of course, the use of Kaspersky Security Network is entirely out of the user's voluntary, if not joined the security network will not affect the normal use of security forces products. The whole process is truly open and transparent.

Kaspersky Security Network system, not only in the first time to respond to unknown programs, but also from the PC side of the feedback information as an important basis for analysis and judgment, so the accuracy of the security system has also been greatly improved. Let each user become a part of the security network, so as to achieve information sharing or crisis warning, common response to malicious threats, is Kaspersky practice "cloud security" the essence of the idea!
