Sequence diagram for a Wi‑Fi deauthentication attack. Unlike most radio jammers, deauthentication acts in a unique way. The IEEE 802.11 (Wi-Fi) protocol contains the provision for a deauthentication frame. Sending the frame from the access point to a station is called a "sanctioned technique to inform a rogue station that they have been ...
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.
Unix-like operating systems commonly implement IP address blocking using a TCP wrapper, configured by host access control files /etc/hosts.deny and /etc/hosts.allow.. Both companies and schools offering remote user access use Linux programs such as DenyHosts or Fail2ban for protection from unauthorized access while allowing permitted remote access.
Several online retailers and drone technology companies are marketing the sale of radio frequency jammers as drone deterrence or privacy tools, sidestepping federal laws that prohibit such devices ...
Pi-hole is a Linux network-level advertisement and Internet tracker blocking application [3] [4] which acts as a DNS sinkhole [5] and optionally a DHCP server, intended for use on a private network. [1] It is designed for low-power embedded devices with network capability, such as the Raspberry Pi, [3] [6] but can be installed on almost any ...
VPN blocking is a technique used to block the encrypted protocol tunneling communications methods used by virtual private network (VPN) systems. Often used by large organizations such as national governments or corporations, it can act as a tool for computer security or Internet censorship by preventing the use of VPNs to bypass network ...
Laws regarding "unauthorized access of a computer network" exist in many legal codes, though the wording and meaning differs from one to the next.However, the interpretation of terms like "access" and "authorization" is not clear, and there is no general agreement on whether piggybacking (intentional access of an open Wi-Fi network without harmful intent) falls under this classification.

This makes it possible, without the need of a physical Wi-Fi router, to share the wired network access of one computer with wireless clients connected to that soft AP. If an employee sets up such a soft AP on their machine without coordinating with the IT department and shares the corporate network through it, then this soft AP becomes a rogue AP.
