Enhancing LAN Security by Mitigating Credential Threats via HTTP Packet Analysis with Wireshark

Abstract

The world is connected digitally and the security of Local Area Networks has been dangerous increasingly. A process that is especially designed to secure networks from different ouside attacks is known as Cybersecurity. In this article, a Local Area Network threat scenario is discovered especially concentrating on the extraction of credentials by capturing the Hypertext Transfer Protocol packets. Most of the time, Local Area Network can be said a secure, but sometimes itcan have many vulnerablities to cybersecurity threats. An attacker can be connected with Local Area Network and using packets capturing and network anlysing tool wireshark; they can exploit the Hypertext Transfer Protocol vulnerabilities to obtain login credentials. Attackers have motives to get specific credentials, they perform actions to get IP addresses, emal addresses being used in communication and financial details, by network trffic examination. Differenet protocols such as Hypertext Transfer Protocol, Address Resolution Protocol, and Transmission Control Protocol are can be captured and analyzed by this tool. To get filtered packets, Wireshark provides the best filtering selections and interpret into packets. For the security of Local Area Network, implementation of various security approaches including encryption of data and protocols, Firewall, IDS/IPS implementation, network segmentation, ethernet cables usage, use of Hypertext Transfer Protocol Secure and Multifactor authentication is deployed. Network traffic should be monitored, apply port security, and allow only registered Media Access Control in Access Point. The proposed solution enhanced the security of the Local Area Network and mitigated the cybersecurity threats. Network and connected devices monitoring regularly and activity of traffic packet-capturing tools can make the Local Area Network more secure.
