Network forensics is fairly a new area of research which would be used after an intrusion in various organizations ranging from small, mid-size private companies and government corporations to the defense secretariat of a country. At the point of an investigation valuable information may be mishandled which leads to difficulties in the examination and time wastage. Additionally the intruder could obliterate tracks such as intrusion entry, vulnerabilities used in an entry, destruction caused and most importantly the identity of the intruder. This paper was to map the correlation between network security and network forensic mechanisms. There are three sub research questions that had been studied.
