Internet technology, networks and other computer components are advancing at a high speed rate and with their widespread development are improving certain aspects of our life from a different range of categories, and as we rely heavily on the reliability of all digital devices, there are certain things that can affect their proper functioning. This section deals with criminal activities that can be carried out in all forms of digital attacks. So every type of digital technology carries with it certain disadvantages, vulnerabilities that can be exploited for negative purposes. In this paper, we will explain the principle of digital forensics that is done in terms of conducting investigations that investigate computers, networks, digital data, and malware. We will explain some of the online digital forensic techniques, its issues, methodology, security, protocols, evidence gathering, and the ability to protect against attacks to prevent the use of online resources for criminal activities. The aim of this paper is to present vulnerabilities of certain protocols, where a specific attack will be displayed and compared and their speed for certain segments, an understanding of the prevention and detection system, as well as an overview of traffic that occurs during an attack and its exploitation for further compromising network security.
