KPMG expert: Wi-Fi security still too complicated

Although the 802.1x access protocol is a must for wireless network security, companies rarely use it and thus leave the door open for hackers, according to Robert Lamprecht, IT advisory supervisor at KPMG.

The protocol lets users on either wireless or wired local networks set up a connection and prevent others from accessing the port they are trying to use if authentication fails.

"With 802.1x unauthorized users can't get access to your network; without it you are vulnerable to people who can come in and steal information," said Lamprecht, who spoke at the European Computer Audit Control and Security Conference in Stockholm.
