Abstract: A method of detecting a malware based on a white list comprises: receiving on a server side a program feature and/or a program behavior of a program to be detected sent from a client side; comparing the program feature and/or the program behavior of the detected program with legitimate program features and/or legitimate program behaviors stored in a white list; obtaining a legitimacy information of the unknown program based on the comparison result and feeding this back to the client side. In the invention, a legitimate program is determined by using a white list, thereby determining an illegitimate program excluded from the white list as a malware, which performs a determination and detecting and removing of a malware from another perspective.

Abstract: The present invention relates to an active defense method based on cloud security comprising: a client collecting and sending a program behavior launched by a program thereon and/or a program feature of the program launching the program behavior to a server; with respect to the program feature and/or the program behavior sent by the client, the server performing an analysis and comparison in its database, making a determination on the program based on the comparison result, and feeding back to the client; based on the feedback determination result, the client deciding whether to intercept the program behavior, terminate execution of the program and/or clean up the program, and restore the system environment. The invention introduces a cloud security architecture, and employs a behavior feature based on active defense to search and kill a malicious program, thereby ensuring network security.

Abstract: A method for the formation of a membrane is described. A collection of substantially spherical particles formed from a selected material is contacted with at least one reactive material. The reactive material is cured or otherwise polymerized by various techniques, so that it forms a matrix that substantially surrounds and contains the particles.
