Abstract

See full text

Optimizing data security using fragment assembly is described. Additionally, optimizing security in data traffic is also described, including reassembling data traffic using a fragment, scanning a datagram in the data traffic in accordance with a protocol, and detecting an anomaly in the data traffic based on evaluating the datagram. By scanning and detecting an anomaly contained in a data fragment, packet, segment, stream or other encapsulation technique, further processing may be invoked in order to determine whether a threat or attack to an end host exists.
