High bandwidth wireless local area networks are gaining popularity. Along with this
popularity has come a well publicized series of vulnerabilities in the IEEE standard
implementations. In response, a number of standards from wired networking (e.g. 802.1x
and IPsec) are being adopted to wireless. Vendors are also developing and selling
proprietary security solutions. The normal security risk assessment/risk mitigation
process can be complicated by a misunderstanding of the range of available options and
the strengths and weaknesses of each. However, the nature of wireless technology raises
the stakes in performing a proper risk assessment and deploying a wireless network that
meets local security requirements.
This white paper first describes taxonomy of wireless LAN attack techniques. We then
describe the generic mechanisms available for authentication of users and the protection
of the privacy and integrity of the data. We conduct a basic analysis of each security
countermeasure by looking at the attack techniques addressed by the mechanism. Our
analysis takes into account the perspective of both insiders and outsiders. We conclude
by stating our recommendations for WLANs. These recommendations include:
· Mutual Authentication
· Layer two encrypted tunnel
· Strong cryptographic integrity verification
Without these features, not only is a WLAN vulnerable, but the entire information
infrastructure of which it is a part is at risk. We also recommend per-packet
authentication although we would not go so far as to make it a requireme nt. |
