Network forensics is the process of capturing, recording, and analyzing network traffic to identify and investigate security incidents.
Description
Network forensics is a crucial aspect of cybersecurity that involves the analysis of network traffic data to uncover unauthorized activities and security breaches. This discipline helps security professionals determine how an attack occurred, what data was compromised, and the methods used by attackers. By capturing packets of data that flow through a network, forensic analysts can reconstruct events leading up to an incident. For example, in a case of a data breach, network forensics could help trace the path of the attacker, identify vulnerable systems, and assess the extent of the damage. Tools like Wireshark and tcpdump are often used to capture and analyze this traffic. Additionally, network forensics plays a vital role in compliance with regulations such as GDPR and HIPAA, ensuring that organizations can effectively respond to security incidents and protect sensitive information.
Examples
- In 2017, the Equifax data breach utilized network forensics to identify the exploitation of a vulnerability in their web application framework.
- During the Target data breach in 2013, network forensics helped investigators trace the malware that compromised credit card information of millions of customers.
Additional Information
- Network forensics can help organizations develop better security policies and incident response plans.
- It often involves collaboration with law enforcement agencies to aid in criminal investigations related to cyber crimes.
