IT contractors helping firms with their Wi-Fi networks need to ensure that access for authorised users is as easy as possible, it has been claimed.

Network security systems need to be able to find and identify security threats and deal with them appropriately, without putting blocks on sites, according to networking solutions firm Brocade.

Internet-giant Google inadvertently highlighted the problem presented by Wi-Fi networking when it was found to have collected data sent over Wi-Fi networks via its Street View cars.

The American company insists the data was harvested accidentally and was never used in any of its applications.

Brocade's systems engineer and pre-sales manager for UK and Ireland Simon Pamplin said that security programs will always be breached, so large-scale blocking will still not fully protect a network.

"You have to provide remote capabilities and secure them in the same way as though you were connected to a secure network within your own controlled campus," he added.
