The IEEE 802.11i standard
will plug all known security holes in IEEE 802.11 wireless
LANs, also known as Wi-Fi, but probably won't see final approval
or shipping products until about a year from now, according
to an Intel network architect involved in the drafting of
the standard who spoke at Intel's Spring Developer Forum last
week.
However, technical
advances already available can make wireless
LANs far more secure than they originally were. Also,
to give themselves some protection, many companies could start
by simply using what came with 802.11 to start with, said
a Cisco Systems engineer who spoke at the same session.
WEP, or Wired Equivalent
Privacy, the security mechanism initially built into all standard
802.11
products , encrypts data on the wireless network but is
flawed because it reuses the same encryption key, said Jesse
Walker, a network architect at Intel and the editor of the
802.11i standard now in development under the Institute of
Electrical and Electronics Engineers. A would-be hacker can
figure out that key from a small amount of traffic, he said.
WEP also doesn't stop interlopers from altering data as it
crosses the network, he added.
