Chapter 6 - Three Phases for a Secure Wireless Network

Abstract

This chapter divides the implementation of a complete secure wireless network into three phases: Unified Threat Management (UTM) gateway and wireless access, secure remote access, and centralized management. By dividing the implementation into three phases, a clear view of how the SonicWALL product line fits together to form a single, integrated network solution is achieved. The phased approach also helps a network designer determine which elements the network requires. This chapter explains all of the concepts necessary to understand the implementation sections that follow. Phase one covers the configuration of gateway devices with UTM security services and then the addition of wireless service. SonicWALL's UTM services use the deep packet inspection (DPI) engine to examine both the header and body of every packet that enters the network. Phase two covers VPN solutions that add secure remote access to the network. SonicWALL provides both client and clientless solutions, with several options for extra security such as two-factor authentication (2FA) and one-time passwords (OTPs). Phase Three adds centralized management and monitoring for larger networks. SonicWALL Global Management System (GMS) allows a single network administrator to remotely configure an entire network consisting of multiple appliances located in multiple remote sites from a single local management interface.
