The Role of Wireshark in Packet Inspection and Password Sniffing for Network Security

Abstract

In today's interconnected digital landscape, network integrity, efficiency, and security are paramount for business, institutional, and personal interactions. This chapter focuses on delving into the functionalities of Wireshark, offering an extensive exploration of packet inspection methodologies and effective strategies to mitigate the risks associated with password sniffing attacks. It involves capturing and analyzing network traffic, examining key protocols like HTTP, DNS, SMTP, and more, and demonstrating data transmission across the network Through practical demonstrations readers are guided through the process of deploying Wireshark to capture and analyze network packets in real-time. Focused on thwarting password sniffing—a common tactic used by adversaries to intercept and decrypt sensitive data, including login credentials. Wireshark enables readers to identify and counter common password-sniffing techniques. The chapter also covers proactive steps like adopting secure protocols, encryption algorithms, and best password management practices.
