Security analysis in wireless networks

Abstract

Wireless networks have become essential to our daily lives, providing connectivity for a wide range of devices. However, with the increasing use of wireless networks, security has become a major concern. Media Access Control (MAC) address flooding, Dynamic Host Configuration Protocol (DHCP) spoofing, and rogue Secure Shell (SSH) are some of the most common security threats in wireless networks. These attacks can cause loss of confidentiality, integrity, and availability of network resources. In this study, vulnerabilities and challenges related to MAC address flooding, DHCP spoofing, and rogue SSH attacks were investigated. Analysis of the solution to prevent and mitigate these attacks was performed by network simulation using the Cisco Packet Tracer Windows version 8.1.1. The system design would provide a user-friendly interface for network administrators to monitor their networks and check for anomalies. The analysis indicated that Port Security effectively limited unauthorized MAC addresses, DHCP snooping successfully blocked illegitimate DHCP responses, and Access Control Lists restricted rogue SSH access, supporting these methods as optimal solutions for mitigating the respective security threats.
