Abstract
A method and apparatus for identifying data patterns of a file are described herein. In one embodiment, an exemplary process includes, but is not limited to, receiving a data packet of a data stream containing a file segment of a file originated from an external host and destined to a protected host of a local area network (LAN), the file being transmitted via multiple file segments contained in multiple data packets of the data stream, and performing a data pattern analysis on the received data packet to determine whether the received data packet contains a predetermined data pattern, without waiting for a remainder of the data stream to arrive. Other methods and apparatuses are also described.
