Abstract
An intrusion detection system employs a pointer fingerprint method for detecting attempted or successful intrusions into an information system or network. In a pointer fingerprint method, the specific stream of bits searched from the traffic streams is a pointer or part of it that must be included in all working buffer overflow (bof) attacks. This makes it possible to detect also the previously unknown bof attacks.
