Enhancing Your Wireless Security
Security can only improve (Figure 18.3) when:
1. The vendor of the wireless product implements greater safeguards
(beyond what the specification has defined) to improve security.
2. The administrator in your company implements all these safeguards
(and then some) to lock down user access to any wireless resource on
your WLAN.
Unauthorized access is a primary concern for any current Wi-Fi applications.
Improving on security demands that the data stream be protected
with encryption and that user access be protected through authentication.
WLANs may evolve to integrate PKI types of access barriers that allow
selective access requiring only specific credentials. This type of access
depends on granting a digital certificate to a user when he logs into your
network. Such a certificate will only allow the user to access certain networked
resources. This type of mechanism allows you to retain control
over who accesses your network and what resources they can use.
