Description: Network Forensic Methodology is a systematic approach to conducting forensic investigations in the realm of computer networks. This methodology focuses on the collection, analysis, and preservation of data that can be crucial for understanding security incidents, fraud, or criminal activities occurring in digital environments. Through specific techniques, forensic experts can identify behavioral patterns, trace intrusions, and determine the origin of cyberattacks. The methodology includes several phases, such as evidence identification, data collection, forensic analysis, and results presentation. Each of these stages is essential to ensure that the information obtained is valid and admissible in a legal context. Network Forensic Methodology is applied not only in criminal investigations but also in security audits and incident recovery in various organizations, making it an essential tool for information protection and network integrity.
History: Network Forensic Methodology began to take shape in the late 1990s, when the increase in Internet connectivity and the use of corporate networks led to a rise in cybercrime. As network technologies evolved, so did forensic techniques to address new challenges. In 2001, the book ‘Computer Forensics: Principles and Practices’ by John Sammons helped establish a theoretical framework for digital forensic investigation, including aspects related to networks. Since then, the methodology has continued to evolve, adapting to new technologies and emerging threats.
Uses: Network Forensic Methodology is primarily used in the investigation of security incidents, such as malware attacks, unauthorized intrusions, and online fraud. It is also applied in security audits to assess network integrity and in data recovery after security incidents. Additionally, it is used by law enforcement agencies to collect evidence in cases of cybercrime.
Examples: An example of the application of Network Forensic Methodology is the investigation of the WannaCry ransomware attack in 2017, where experts analyzed network traffic to identify the spread of the malware. Another case is the investigation of the Target data breach in 2013, where forensic techniques were used to trace the origin of the attack through the company’s network.
