  • Method and Apparatus to Facilitate Generating Worm-Detection Signatures Using Data Packet Field Lengths
    Publication number: 20090158433
    Abstract: Network-level data traffic comprising data packets, wherein at least some of the data packets have at least one field of unbounded length, are received (101). A worm-detection signature is then generated (102) as a function, at least in part, of the lengths of particular data packet fields. So configured, these teachings are particularly suitable for use in detecting worms that seek to exploit the use of an unbounded field in a data packet to overwhelm buffer memory in a receiving network element as a basis for installing the worm's code.
