Network Forensics: A Comprehensive Review of Tools and Techniques

With the evolution and popularity of computer networks, a tremendous amount of devices are increasingly being added to the global internet connectivity. Additionally, more sophisticated tools, methodologies, and techniques are being used to enhance global internet connectivity. It is also worth mentioning that individuals, enterprises, and corporate organizations are quickly appreciating the need for computer networking. However, the popularity of computer and mobile networking brings various drawbacks mostly associated with security and data breaches. Each day, cyber-related criminals explore and devise complicated means of infiltrating and exploiting individual and corporate networks' security. This means cyber or network forensic investigators must be equipped with the necessary mechanisms of identifying the nature of security vulnerabilities and the ability to identify and apprehend the respective cyber-related offenders correctly. Therefore, this research's primary focus is to provide a comprehensive analysis of the concept of network forensic investigation and describing the methodologies and tools employed in network forensic investigations by emphasizing on the study and analysis of the OSCAR methodology. Finally, this research provides an evaluative analysis of the relevant literature review in a network forensics investigation.
