IEEE 802.11i enhances IEEE 802.11-1999 by providing a Robust Security Network (RSN) with two new protocols: the four-way handshake and the group key handshake. These utilize the authentication services and port access control described in IEEE 802.1X to establish and change the appropriate cryptographic keys.
802.1X-2001 defines two logical port entities for an authenticated port—the "controlled port" and the "uncontrolled port". The controlled port is manipulated by the 802.1X PAE (Port Access Entity) to allow (in the authorized state) or prevent (in the unauthorized state) network traffic ingress and egress to/from the controlled port.
These include design flaws in the Wi-Fi standard, affecting most devices, and programming errors in Wi-Fi products, making almost all Wi-Fi products vulnerable. The vulnerabilities impact all Wi-Fi security protocols, including WPA3 and WEP. Exploiting these flaws is complex but programming errors in Wi-Fi products are easier to exploit.
An air gapped network (right) with no connection to a nearby internet-connected network (left) An air gap, air wall, air gapping [1] or disconnected network is a network security measure employed on one or more computers to ensure that a secure computer network is physically isolated from unsecured networks, such as the public Internet or an unsecured local area network.

In addition, the PRIVATE WiFi icon in the system tray turns from red to green. To deactivate PRIVATE WiFi: 1. Right-click on the PRIVATE WiFi icon in your system tray. 2. Select Deactivate. PRIVATE WiFi is deactivated. Note: Even though PRIVATE WiFi is deactivated, it is still running in the background of your computer. The PRIVATE WiFi icon in ...
PRIVATE WiFi will automatically activate and connect to an encrypted server whenever you access the internet. If you change this default setting, you can activate PRIVATE WiFi at any time clicking on the status icon ( PC: right-click the icon in the Taskbar at the bottom right of your screen, Mac: click the Menu Bar icon at the top right of ...
Network access control (NAC) is an approach to computer security that attempts to unify endpoint security technology (such as antivirus, host intrusion prevention, and vulnerability assessment), user or system authentication and network security enforcement.
Network Admission Control (NAC) refers to Cisco's version of network access control, which restricts access to the network based on identity or security posture.When a network device (switch, router, wireless access point, DHCP server, etc.) is configured for NAC, it can force user or machine authentication prior to granting access to the network.
