Our paper comprehensively examines ways to detect and handle unauthorized switches in Local Area Networks (LANs) within today's intricate and interconnected network landscape. We demonstrate the utilization of PortFast and BPDU guard configurations to reinforce LAN security against unauthorized devices and potential complications arising from the spanning tree protocol. These measures not only enhance network performance but also function as robust protective mechanisms, safeguarding the integrity of the LAN infrastructure.

Furthermore, this paper delves into advanced techniques for the proactive identification and prevention of rogue switches, fostering an overall enhanced security posture within LANs. By synergistically integrating PortFast, BPDU guard, and advanced rogue switch detection methods, the paper proposes a robust methodology to strengthen LAN security and maintain uninterrupted network operations. It equips organizations with crucial resources to establish a resilient, secure, and dependable digital infrastructure, addressing the evolving demands of network security.
