摘要： In accordance with particular embodiments, a method includes intercepting a communication and extracting metadata associated with the communication. The extracted metadata comprises a plurality of different fields from communication metadata and file metadata. The method further includes determining a score, based on previous communications, for each field of the extracted metadata. The score is indicative of a likelihood that the communication is a malicious communication. The method additionally includes combining the scores to generate a combined score for the communication based on an algorithm developed from the previous communications. The method also includes generating, based on the combined score at a first time, a predicted classification as to whether the communication is a malicious communication. The method further includes receiving, at a second time subsequent to the first time, an indication of whether the communication is a malicious communication and updating the algorithm based on the indication.

摘要： A computer-implemented method includes accessing, by an analysis console, information related to a first file received at a first host of a plurality of hosts. Each host is capable of running a corresponding set of malware detection processes. The information includes: an identifier of the first file; and data indicating a first result of the first host applying the set of malware detection processes to the first file. The identifier is generated by the first host and is usable by each of the hosts to determine whether a second file comprises content substantially equivalent to content of the first file. The analysis console generates a first output including: the identifier of the first file; and a second result indicating whether the first file comprises malware. The second result is usable by each of the hosts to determine whether the second file comprises malware. The first output is propagated to the hosts.

摘要： In certain embodiments, a method includes receiving, at a proxy, a request for access to a network from an application on an endpoint. The method also includes determining, by the proxy, information about the application on the endpoint by examining one or more headers of the request received at the proxy from the application. The method further includes determining, by the proxy, whether the one or more headers comprise expected information based on the determined information about the application. In response to determining that the one or more headers do not comprise the expected information, the method includes denying, by the proxy, the request for access to the network. In addition, in response to determining that the one or more headers comprise the expected information, the method includes forwarding, by the proxy, the request to the network on behalf of the application.
