Content leaving a local network can be captured and indexed so that queries can be performed on the captured data. In one embodiment, the present invention comprises an apparatus that connects to a network. In one embodiment, this apparatus includes a network interface module to connect the apparatus to a network, a packet capture module to intercept packets being transmitted on the network, an object assembly module to reconstruct objects being transmitted on the network from the intercepted packets, an object classification module to determine the content in the reconstructed objects, and an object store module to store the objects. This apparatus can also have a user interface to enable a user to search objects stored in the object store module.

Method and apparatus for data capture and analysis system

Objects captured over a network by a capture system can be indexed to provide enhanced search and content analysis capabilities. In one embodiment the objects can be indexed using a data structure having a source address field to indicate an origination address of the object, a destination address field to indicate a destination address of the object, a source port field to indicate an origination port of the object, a destination port field to indicate a destination port of the object, a content field to indicate a content type from a plurality of content types identifying a type of content contained in the object, and a time field to indicate when the object was captured. The data structure may also store a cryptographic signature of the object to ensure the object is not altered after capture.

Tag data structure for maintaining relational data over captured objects

Objects can be extracted from data flows captured by a capture device. Each captured object can then be classified according to content. Meta-data about captured objects can be stored in a tag. In one embodiment, the present invention includes receiving a request to present a previously captured object to a user, accessing a tag associated with the requested object, the tag containing metadata related to the object, the metadata including an object signature, and verifying that the object has not been altered since capture using the object signature before presenting the object to the user.
