Kaspersky Lab, an antivirus and Internet security software provider, has patented a method and system for protecting cloud services used by antivirus solution developers. Patent no. 8661547, issued by the U.S. Patent and Trademark Office, describes a technology that safeguards cloud services against false information that could be sent to them.

The patented technology is deployed in Kaspersky Security Network, the cloud infrastructure supported by Kaspersky's home user, Server Message Block (SMB) and corporate security products. It performs several tests before using any information uploaded from a device to combat cyber-threats and prevent the illegal use of cloud services by cybercriminals.

Kaspersky provided a breakdown of the cloud services technology in a press release:

"The server checks whether the data communication protocol specifications were violated: an unusual sequence of operations or other anomalies while sending data may indicate an attempt by cybercriminals to interfere in the server's operation. The user-side security application, in turn, analyzes the configuration of the user device. The developer can also use other methods to confirm the legitimacy of any uploaded data."

In addition, Kaspersky noted that when the collected information has been analyzed, the system decides what to do with the data it has received, and "a new level of trustworthiness can be assigned to the device based on the results of the device check."

Andrey Efremov, Director of Whitelisting and Cloud Infrastructure Research at Kaspersky Lab and co-author of the new patent, commented on the patent in a prepared statement:

"Kaspersky Security Network is a key element in Kaspersky Lab's infrastructure. It ensures information about new threats is promptly delivered to users' computers. Of course, this is an attractive target for cybercriminals who want to compromise the security of hundreds of thousands of computers at one time. Therefore, it is important for us to protect Kaspersky Lab's infrastructure against these attacks and prevent fake information from penetrating into antivirus databases."

Kaspersky is the world's largest privately-held vendor of endpoint protection solutions, and as of last month, held 195 patents issued in the U.S., Russia, the European Union and China. Most of Kaspersky's patents cover technologies related to IT security solutions.

In January 2013, Kaspersky Lab CEO Eugene Kaspersky told The VAR Guy that his company was working on a cyber secure operating system for financial systems, nuclear reactors, utilities and other companies. The system is designed to help companies protect their IT systems against cyber warfare and cyber terrorism attacks.
