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."  aPROTECÇÃO DE SOFTWARE9329941  aSEGURANÇA INFORMÁTICA9273163  aREDE INFORMÁTICA9263197  aESTADOS UNIDOSbCognio9334103  xOferta  104PJCD_66_00000000000000052022-06-066PJCD669414437aPJcPJfPJ1CD66_48kPJCD66n2022-06-06o0rMOxOferta
