Methods and apparatus involve the mitigation of security threats at a computing endpoint, such as a server, including dynamic virtual machine imaging. During use, a threat assessment is undertaken to determine whether a server is compromised by a security threat. If so, a countermeasure to counteract the security threat is developed and installed on a virtual representation of the server. In this manner, the compromised server can be replaced with its virtual representation, but while always maintaining the availability of the endpoint in the computing environment. Other features contemplate configuration of the virtual representation from a cloned image of the compromised server at least as of a time just before the compromise and configuration on separate or same hardware platforms. Testing of the countermeasure to determine success is another feature as is monitoring data flows to identifying compromises, including types or severity. Computer program products and systems are also taught.

Systems and methods are described for synergistically combining static file based detection and behavioral analysis to improve both threat detection time and accuracy. An endpoint security solution running on an endpoint device generates a static analysis score by performing a static file analysis on files associated with a process initiated on the endpoint device. When the static analysis score meets or exceeds a static analysis threshold, then a network security platform treats the process as malicious and blocks execution of the process. When the static analysis score is less than the static analysis threshold, then the endpoint security solution obtains a dynamic analysis score for the process. The network security platform treats the process as malicious and causes execution of the process to be blocked based on a function of the static analysis score and the dynamic analysis score.

An endpoint security system having a Secured Authentication For Enterprise (SAFE) server is enhanced with an auxiliary service. The auxiliary service receives a request to run a job on an endpoint of an enterprise computer network, queues up the job in a central job store, and monitors whether an agent on the endpoint has checked in with the SAFE server. Responsive to the agent on the endpoint checking in with the SAFE server, the auxiliary service establishes, through a secure connection with the SAFE server, a connection with the agent on the endpoint and determines whether the agent has any jobs queued up in the central job store. If so, the auxiliary service dispatches the job from the central job store to the agent on the endpoint through the secure connection with the SAFE server and starts the job by the agent on the endpoint.

A communication network processes intermediate security data from intermediate access nodes on a communication path between a network access node and an end-point device to determine if the intermediate access nodes are authorized. If the intermediate access nodes are authorized, then the network processes end-point security data from the end-point device to determine if the end-point device is authorized. If the end-point device is authorized, then the network processes end-point tethering data from the end-point device to determine if any tethered communication devices are coupled to the end-point device. If the end-point device is not coupled to any tethered communication devices, then the network authorizes a data transfer session for the end-point device over the communication path. If the end-point device is coupled to a tethered communication device, then the network denies authorization for the data transfer session over the communication path for the end-point device.

Systems, methods, and apparatuses enable deploying and executing a security policy on endpoints in a network. In an embodiment, a security orchestrator determines a set of endpoints in a network and determines transformed endpoints from the determined set of endpoints through an endpoint transformation process. The security orchestrator determines a connectivity vector for at least a first transformed endpoint and a second transformed endpoint, where the connectivity vector includes properties associated with the corresponding transformed endpoint. Using the properties from the connectivity vector of the first transformed endpoint, a security policy is generated and deployed to the first transformed endpoint. Based on a comparison of the connectivity vectors of the first and second transformed endpoints indicating a similarity between the first and second transformed endpoints, the security policy is further deployed to the second transformed endpoint.

The invention provides an endpoint file security check result information uploading method, apparatus and device, and a medium. The method comprises the steps of obtaining to-be-uploaded information obtained after endpoint security software performs security check on an endpoint; the information to be uploaded comprises a suspicious file and a file path of the suspicious file; acquiring an uploading strategy determined by a user based on the scene condition of the endpoint; performing desensitization processing on the to-be-uploaded information based on the uploading strategy to obtain desensitized information; and uploading the desensitization information to a management center. According to the scheme, the information to be uploaded is desensitized by using the uploading strategy, so that the desensitized information contains sensitive information as little as possible, and then the desensitized information is uploaded to the management center, so that the sensitive information uploaded to the management center can be reduced, and the leakage of the sensitive information is reduced.

Systems and methods for adjusting the behavior of an endpoint security agent based on a network location are provided. According to an embodiment, an agent of an endpoint device detects whether the endpoint has moved to a new network by monitoring for changes to an IP address associated with the endpoint.

When the identifying is affirmative, a particular security feature on the endpoint is configured for operation within a trusted network and when the identifying is negative, the particular security feature is configured for operation outside of a trusted networks.
