According to one embodiment, a computer-implemented method for execution on one or more processors includes receiving a first file and determining a file type of the first file. The method also includes determining, according to a first policy, a plurality of malware detection schemes to apply to the first file based on the determined file type of the first file. In addition, the method includes scheduling the application of the determined plurality of malware detection schemes to the first file amongst a plurality of detection nodes according to a second policy. Further, the method includes determining, in response to determining the results of applying the plurality of malware detection schemes, that the first file is malware or determining that the first file is suspected malware according to a third policy.

System and method for malware detection

A method of verifying integrity of a digital file includes receiving the digital file subsequent to exposure to a foreign environment and validating the digital file. The received digital file has an appended signature label that includes one or both of a first hash value and a digital signature. Validating the digital file includes hashing the digital file to obtain a second hash value, retrieving the first hash value from the signature label, and comparing the first hash value and second hash value.

Data security method and system

According to one embodiment, a computer-implemented method includes: accessing a set of configuration parameters, accessing a set of identifiers of files known not to be malware, and accessing a set of identifiers of files known to be malware. Further, the method includes: comparing a first file to the set of configuration parameters, determining that a first hash of the first file is not in the set of identifiers of files known not to be malware and that the first hash is not in the set of identifiers of files known to be malware, and sending the at least one file and information related to the at least one file to be analyzed for malware. The method includes deleting the set of configuration parameters, the set of identifiers of files known not to be malware, and the set of identifiers of files known to be malware after sending the first file.

System and method for host-level malware detection

According to one embodiment of the invention, a computer implemented method for computing a data integrity algorithm on a data stream comprises the acts of initializing a plurality of threads, partitioning the data stream into a plurality of data stream segments, calculating a number of data integrity values from the plurality of data stream segments, and verifying the integrity of the data stream using the data integrity values. The plurality of threads are executed at generally the same time. Each of the data integrity values are derived from an associated data stream segment.
