Kaspersky Security Network (KSN) is a complex distributed infrastructure dedicated to processing depersonalized cybersecurity-related data streams from millions of voluntary participants around the world. It delivers Kaspersky Lab’s security intelligence to every partner or customer who is connected to the Internet, ensuring the quickest reaction times and maintaining the highest level of protection. KSN functionality is incorporated into the most of Kaspersky Lab’s consumer and business products.
Being part of Kaspersky System Watcher, this technology analyses the most relevant system event data, including information on the modification of files. When it registers a suspicious application attempting to open a user’s personal files it immediately makes a local protected backup copy of them. If the application is then judged to be malicious, Kaspersky System Watcher automatically rollbacks unsolicited changes.
