According to one embodiment, a system features a network security device and a cloud computing service. The network security device is configured to determine whether an object includes one or more characteristics associated with a malicious attack. The cloud computing service, communicatively coupled to and remotely located from the network security device, includes virtual execution logic that, upon execution by a processing unit deployed as part of the cloud computing service and after the network security device determining that the object includes the one or more characteristics associated with the malicious attack, processes the object and monitors for behaviors of at least the object suggesting the object is associated with a malicious attack.

System and method for offloading packet processing and static analysis operations

System and method for separated packet processing and static analysis

According to one embodiment, a system features analysis circuitry and detection circuitry. The analysis circuitry features a first processing unit and a first memory that includes a filtering logic configured to produce a second plurality of objects from a received first plurality of objects. The second plurality of objects is a subset of the first plurality of objects. The detection circuitry is communicatively coupled to and remotely located from the analysis circuitry. The detection circuitry includes a second processing unit and a second memory. The second memory includes a virtual execution logic to process content within at least a first object of the second plurality of objects. The virtual execution logic is configured to monitor for behaviors, during the processing of the first object, and determine whether any or all of the monitored behaviors correspond to activities indicative that the first object is associated with a malicious attack.

According to one embodiment, a network security device configured to detect malicious content within received network traffic comprises a traffic analysis controller (TAC) is provided. The traffic analysis controller comprises a network processing unit (NPU) and is configured to perform at least packet processing on the NPU with a set of pre-filters. In addition, the network security device further comprises a central processing unit (CPU) and is configured to perform at least virtual machine (VM)-based processing. The set of pre-filters is configured to distribute objects of received network traffic such that either static analysis or dynamic analysis may be performed on an object to determine whether the object contains malicious content. The static analysis may be performed on either the NPU or the CPU while the dynamic analysis is performed on the CPU.
