CHAPTER 4Understanding Domain and Wi-Fi Design Impacts
Any system is best when designed with the entire ecosystem in mind, and security architecture for wireless is no exception. Proper design balances business objectives with security for a holistic approach.
As such, security can't be planned in a vacuum. The wireless infrastructure is one piece within the greater enterprise environments of networked systems and security programs. This chapter highlights just a few of the many related domain services and non-security Wi-Fi design elements that impact or play a crucial role in security architecture and covers the following:

Understanding Network Services for Wi-Fi
IP-based wireless technologies rely on a multitude of fundamental networking and domain services including Domain Name System (DNS), Dynamic Host Configuration Protocol (DHCP), and time services to name a few. Yeah, I know—you think all of that's boring. Well, it may be, but it's also now remarkably complex and something that needs to be addressed.
It's probably a safe generalization to say those of us that began working with Wi-Fi early on (for me it was mid-to-late-’90s) all had a relatively accomplished level of networking background as a foundation. Learning Wi-Fi (at that time) only required a bit of additional knowledge around RF as a different layer 1 medium, and the added layer 2 protocols to facilitate passing IP ...
