Abstract: Forensic readiness is a crucial component of modern cybersecurity, enabling organizations to effectively detect, analyze, and respond to security incidents. In a landscape where cyber threats are becoming increasingly sophisticated, forensic readiness ensures that organizations are prepared to collect and preserve digital evidence in a way that supports investigative processes and legal proceedings. This paper explores the role of network traffic capture tools, such as tcpdump and Wireshark, alongside log analysis, in forensic readiness. Tcpdump, a command-line tool for network packet capture, and Wireshark, a graphical network protocol analyzer, are instrumental in collecting real-time network data and identifying suspicious activities during security incidents. Log analysis plays a complementary role by providing detailed records of system and application events, helping investigators build a comprehensive timeline of the attack. Together, these tools enable organizations to monitor network traffic, correlate system activities, and preserve evidence, ensuring a rapid and efficient response to cyber threats. This paper discusses the features, practical applications, and benefits of using tcpdump, Wireshark, and log analysis in forensic investigations, highlighting their critical role in enhancing cybersecurity defenses and ensuring regulatory compliance.
