There's always the chance that an attacker can spoof either the bssid or any other info that identifies de AP on the 
network.

Wireless jamming isn't legally allowed in some countries, here you have some examples

Remember that an AP can be posed by any laptop.

I'll develop on my previous reply at the end of this reply, and remember this IS case specific. I'll only talk about

Consider this scenario, the network as a RADIUS server used to authenticate users, the company that owns the network 
provides a certificate for each user to install and have each supplicant (client) compare it with the one provided by

Securing Apache Web Server with thawte Digital Certificate
In this guide we examine the importance of Apache-SSL and who needs an SSL certificate.  We look at how SSL works, how 
it benefits your company and how your customers can tell if a site is secure. You will find out how to test, purchase, 
install and use a thawte Digital Certificate on your Apache web server. Throughout, best practices for set-up are 
highlighted to help you ensure efficient ongoing management of your encryption keys and digital certificates.
