WiMAX stands for Worldwide interoperability for Microwave Access which is also known as IEEE 802.16 wireless metropolitan area network. It basically an alternative to wired technologies such as cable modems, DSL (Digital Subscriber Line), T1/E1 lines and provides broadband access over long distances. It has many advantages like high data rates, quality of service, scalability, security and mobility. In this paper, the author have discussed about the most concerned issue of security in broadband wireless network access i.e. WIMAX. The security in WIMAX is involved with certain vulnerabilities, threats and risks or attacks.
