The DDoS and botnet attacks are mostly observed in the distribution networks, and the traceback technique is useful in such attacks. Reference [5] proposed a GUI-based monitoring system in which the server carries out the analysis of the network packets and then transmits them to client nodes for storage. It is also important for police force investigations. The forensic network servers for analysis collect the data from different data server agents located at various locations in the network. To identify the network datas susceptibilities, it is necessary to record the data packets at high speed; however, it is a very time-consuming process.

Furthermore, the ISPs should stop the malicious packets of data, which may result in network attacks. and reconstruct the session. One of the key motivational factors that emerged within the forensic network domain includes the emergence of the information technology (IT) industry and its apprehension on security. Regardless of the number of studies that scholars performed on network forensic techniques, Pilli et al. Network Forensics. This technique determines the origin of the attack by identifying the device from where packets are generated. The malicious traffic programs are irregular traffic patterns.

However, investigation of postmortem captures packet is operated offline, Source of data: flow-based process mainly collects statistical records in the form of the flow of network traffic where packet-based tool includes thorough packet inspection. The classification has been carried out based on the target datasets and implementation techniques while performing forensic investigations. Network Miner Need to spot variations in network traffic to detect anomalies. Network Forensics - SlideShare resources requirement; minimize attacks, providing reliable and This technique is particularly useful when the attackers in the system are known. These malicious packets attack the network by exploiting the vulnerabilities of the devices installed for security purposes, which may occur, including the gateways and the attempts to gain unauthorized access in the network. network has been attacked or there is a user error. Most of the available intrusion detection systems detect the connections starting (SYN TCP flag) or ending (FIN TCP flag).
