摘要:
A method is provided in one example embodiment and includes initiating an execution of a compiled script, evaluating a function called in the compiled script, detecting an execution event based on at least a first criterion, and storing information associated with the execution event in an execution event queue. The method also includes verifying a correlation signature based on information associated with at least one execution event in the execution event queue. In specific embodiments, the method includes evaluating an assignment statement of a script during compilation of the script by a compiler, detecting a compilation event based on at least a second criterion, and storing information associated with the compilation event in a compilation event queue. In yet additional embodiments, the verification of the correlation signature is based in part on information associated with one or more compilation events in the compilation event queue.

A system, method, and computer program product are provided for preventing communication of unwanted network traffic by holding only a last portion of the network traffic. In use, network traffic associated with a file transfer is received. Additionally, only a last portion of the network traffic associated with the file transfer is held for determining whether the file is unwanted. Further, the last portion of the network traffic associated with the file transfer is conditionally forwarded to a destination device, based on the determination.

A method is provided in one example embodiment that includes receiving event information associated with reports from sensors distributed throughout a network environment and correlating the event information to identify a threat. A customized security policy based on the threat may be sent to the sensors.

The invention is a method and apparatus for detecting shellcode such that a set of computer instructions is scanned for the presence of a null operation instruction. The computer instructions are also examined for the presence of a system call instruction, and reviewed for the presence of a decoder instruction set. A null operation weight value is then determined corresponding to the null operation instruction. Also assessed is a system call weight value corresponding to the system call instruction. In addition, a decoder weight value is calculated corresponding to the decoder instruction set. The null operation weight value, the system call weight value, and the decoder weight value are then analyzed to identify a shellcode.

A method is provided in one example embodiment that includes generating a fingerprint based on properties extracted from data packets received over a network connection and requesting a reputation value based on the fingerprint. A policy action may be taken on the network connection if the reputation value received indicates the fingerprint is associated with malicious activity. The method may additionally include displaying information about protocols based on protocol fingerprints, and more particularly, based on fingerprints of unrecognized protocols. In yet other embodiments, the reputation value may also be based on network addresses associated with the network connection.
