Wireless security is the prevention of unauthorized access or damage to computers or data using wireless networks, which include Wi-Fi networks. The term may also refer to the protection of the wireless network itself from adversaries seeking to damage the confidentiality, integrity, or availability of the network.
A wireless intrusion detection system (WIDS) monitors the radio spectrum for the presence of unauthorized, rogue access points and the use of wireless attack tools. The system monitors the radio spectrum used by wireless LANs, and immediately alerts a systems administrator whenever a rogue access point is detected.
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.
Internet security awareness or Cyber security awareness refers to how much end-users know about the cyber security threats their networks face, the risks they introduce and mitigating security best practices to guide their behavior. [1] [2] End users are considered the weakest link and the primary vulnerability within a network.
The principal objective is to reduce the risks, including preventing or mitigating cyber-attacks. These published materials comprise tools, policies, security concepts, security safeguards, guidelines, risk management approaches, actions, training, best practices, assurance, and technologies.

Wireless public municipal broadband networks avoid unreliable hub and spoke distribution models and use mesh networking instead. [4] This method involves relaying radio signals throughout the whole city via a series of access points or radio transmitters , each of which is connected to at least two other transmitters.
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.
