Wireless networks have become an essential part of everyday communication, enabling connectivity across homes, businesses, and public spaces. However, their open and shared nature exposes them to a variety of security risks such as unauthorized access, data interception, and malicious attacks. This study examines the key threats facing wireless networks and evaluates traditional security measures including encryption protocols, authentication methods, and network monitoring tools. We highlight the critical role of user behavior and the challenges posed by rogue access points and multi-layered attacks. The findings emphasise that while advanced technical safeguards are vital, simple practices such as strong passwords, regular updates, and user awareness significantly contribute to network protection. Balancing security and performance remains a challenge, but a blended approach of sound network design, vigilant monitoring, and informed users offers effective defense against common wireless threats.
