330			_a"As Wi-Fi becomes common in enterprises, the industry has matured to a standard 3-step process of building out Wi-Fi infrastructure. First, conduct a site survey to determine the optimal number and position of access points for a particular site. Second, deploy the access points and other Wi-Fi gear and fine-tune the network for optimal performance. Third, continually monitor the network using a variety of security solutions, such as special wireless intrusion detection system (IDS) or intrusion prevention system (IPS). Many think that doing these things ensures a successful and secure Wi-Fi roll out. But, that belief can be a critical mistake. What the traditional deployment process and Wi-Fi security products overlook is the physical layer, layer 1 in the OSI stack. In a wired network, layer 1 consists of physical media, such as cables, for carrying traffic. In a Wi-Fi network, layer 1 consists of the spectrum of radio waves. Security solutions such as IDS, IPS, and NAC work at layers 2 and above. They ignore layer 1 entirely. But layer 1 is the foundation of the Wi-Fi network. And, because it is the foundation, an attack at the physical layer can be more devastating than attacks at the higher layers."
