Some organizations prefer an extra layer of security: allowing authorized users only to access protected information from certain computers or workstations. While some authentication systems can recognize and authenticate IP addresses, there is now another way to identify devices. Many BIOS chips can utilize security software that embed security information directly on the BIOS. This information, similar to digital certificates, is recognized by some authentication systems, and ensures that users must access protected networks only from their assigned laptops or other BIOS-based devices.
The bottom line
Creating a secure tunnel for wireless access is a vital element of corporate security, but can be easily undermined by weak user passwords. Without strong authentication, attackers can often access back-end information just as easily as your authorized users.
