Security remains the number one concern for British businesses already using or planning to use wireless connectivity as part of everyday business, according to a survey by Computer Weekly.

Almost two-thirds of firms (64%) put flexibility in their top three reasons for the increasing popularity of wireless networking. Other key motivating factors were productivity (37%) and support for business change (33%).

Asked who benefits most from WLan access, nearly three-quarters of respondents (72%) said it was staff through improved access to the internet and corporate Lan.

Other suggested benefits included departmental-specific functions (stock taking, order entry and so on) and internet access for visitors. Each of these polled votes from around a third (29%) of participants.
 
For more than three-quarters of companies, security is still the single biggest fear factor with wireless technology. VPN is at the forefront of remote access security, in use by 80% of companies, although only 20% use it for wireless Lan access.

Just under half of firms rely on the basic WEP security standard and another 18% use its successor Wi-Fi Protected Access in one form or another, despite their flaws.

Nearly 70% of firms deploy their WLan in a secure firewall zone (or DMZ).

Worryingly, more than a third of companies admitted they had no way of knowing whether their wireless security measures were breached. 

The survey was commissioned by SonicWall and carried out by Computer Weekly.
