New Publication Offers Security Tips for WiMAX Networks
For Immediate Release: October 6, 2009
Government agencies and other organizations planning to use WiMAX -- Worldwide Interoperability for Microwave Access -- networks can get technical advice on improving the security of their systems from a draft computer security guide prepared by the National Institute of Standards and Technology (NIST).
WiMAX is a wireless protocol that can cover an area that incorporates a few miles such as a campus or small town. It has a larger reach than the more familiar “WiFi” networks used in offices or homes, but smaller than wireless areas covered by cell phones. The technology, guided by standards issued by IEEE, originally was designed to provide last-mile broadband wireless access as an alternative to cable, digital subscriber line (DSL) or T1 service. In recent years its focus has shifted to provide a more cellular-like, mobile architecture to serve a broader audience.
WiMAX was used after the December 2004 tsunami in Aceh, Indonesia after the communication infrastructure was destroyed and also after Hurricane Katrina along the coast of the Gulf of Mexico.
Special Publication 800-127 “Guide to Security for WiMAX Technologies” discusses WiMAX technology’s topologies, components, certifications, security features and related security concerns. It covers the IEEE 802.16 standard for WiMAX and its evolution up to the 2009 version.
The main threat to WiMAX networks occurs when the radio links between WiMAX nodes are compromised. The systems are then susceptible to denial of service attacks, eavesdropping, message modification and resource misappropriation.
SP 800-127 recommends taking advantage of built-in security features to protect the data confidentiality on the network. It also suggests that organizations using WiMAX technology should:
