- What are some of the security measures to consider when dealing with
- WIRELESS LANS.
-
- Well, the usual questions concern issues like
- - how sensitive is your data?
- - what kinds of threats are you worried about?
- (including, e.g., who's listening, how good are they,
- loss-of-service? jamming? interference?)
- - how far are you broadcasting?
- - how near are your neighbors
- - how fast is your data rate?
- - what's on the LAN? email only? telnet with passwords? NFS?
-
- If you want a product plug, AT&T / NCR's WaveLAN product uses
- spread-spectrum radio, which is hard to intercept and relatively
- tolerant of noise and other LANs in the same area,
- and offers an optional DES encryption chip (US only, I assume)
- to provide much better security. I forget the bit rate,
- but it's about 2 mb/s, and the PC plugin cards emulate the standard
- PC Ethernet cards, so it's protocol-transparent, just a bit slower.
- I think the range is around 200-300 meters for broadcast and
- 10 km for line-of-sight with a directional antenna.
- Email me if you want more details; I'll try to find some product literature.
