摘要： A method in one example implementation includes receiving information related to a network access attempt on a first computing device with the information identifying a software program file associated with the network access attempt. The method also includes evaluating a first criterion to determine whether network traffic associated with the software program file is permitted and then creating a restriction rule to block the network traffic if the network traffic is not permitted. The first criterion includes a trust status of the software program file. In specific embodiments, the method includes pushing the restriction rule to a network protection device that intercepts the network traffic associated with the software program file and applies the restriction rule to the network traffic. In more specific embodiments, the method includes searching a whitelist identifying trustworthy software program files to determine the trust status of the software program file.

摘要： A method in one example implementation includes obtaining a plurality of host file inventories corresponding respectively to a plurality of hosts, calculating input data using the plurality of host file inventories, and then providing the input data to a clustering procedure to group the plurality of hosts into one or more clusters of hosts. The method further includes each cluster of hosts being grouped using predetermined similarity criteria. In more specific embodiments, each of the host file inventories includes a set of one or more file identifiers with each file identifier representing a different executable software file on a corresponding one of the plurality of hosts. In other more specific embodiments, calculating the input data includes transforming the host file inventories into a matrix of keyword vectors in Euclidean space. In further embodiments, calculating the input data includes transforming the host file inventories into a similarity matrix.

摘要： A method in one example implementation includes intercepting a network access attempt on a computing device and determining a software program file associated with the network access attempt. The method also includes evaluating a first criterion to determine whether the network access attempt is permitted and blocking the network access attempt if it is not permitted. The first criterion includes a trust status of the software program file. In specific embodiments, the trust status is defined as trusted if the software program file is included in a whitelist of trustworthy program files and untrusted if the software program file is not included in a whitelist. In more specific embodiments, the method includes blocking the network access attempt if the software program file has an untrusted status. In further embodiments, an event is logged if the software program file associated with the network access attempt has an untrusted status.
