- Wireless Access Point (WAP) A networking device that enables wireless-capable devices to connect to a wired network. It acts as a communication hub by receiving and transmitting data between the wireless devices and the wired part of the network. WAPs are commonly used in homes and businesses to extend network coverage and allow for seamless internet connectivity for devices like computers, smartphones, and smart home devices.
- Wireless attacks Malicious attempts to compromise or intercept data transmitted over wireless networks. These attacks target vulnerabilities in wireless protocols and devices, ranging from Wi-Fi networks to Bluetooth connections. Wireless attacks can lead to unauthorized access, data breaches, and network disruption. Common examples include eavesdropping, man-in-the-middle attacks, and unauthorized network access. Defenses against these attacks include the use of strong encryption, secure authentication methods, and vigilant network monitoring.
- Wireless computing Any type of computer operation or application that operates without a wired connection. This includes activities such as internet access, file sharing, and device synchronization over a wireless network. It relies on wireless networking technologies like Wi-Fi or mobile data networks to provide connectivity. The benefit of wireless computing is increased mobility and convenience, as users are not tethered by cables and can access network resources from any location within the network's coverage area.
- Wireless Local Area Network (WLAN) A type of network that allows devices to connect and communicate wirelessly within a localized area such as a home, school, office, or café. The most common standard for WLAN is Wi-Fi, which uses radio waves to provide wireless high-speed internet and network connections. In a WLAN, a wireless router serves as the communication hub, transmitting and receiving data from the networked devices.
- Wireless networks Data networks that use electromagnetic waves to connect devices and transmit information without the need for physical wiring. These can range from simple Bluetooth device pairings to complex mobile data networks spanning entire countries. Wireless networks enable flexibility and mobility, allowing devices to connect to the network from anywhere within the signal's range, making them ideal for environments where wired connections are impractical or impossible.
- Wireless technology Any method of data transfer or communication that does not require a physical connection via cables or wires. This encompasses a wide range of technologies and standards, including Wi-Fi for local area networking, cellular networks for mobile communication and internet access, Bluetooth for short-range device-to-device connections, and satellite communications for global coverage. By eliminating the need for physical connections, wireless technology provides increased mobility, convenience, and adaptability.
- Wireshark An open-source tool widely used for network protocol analysis. It allows users to observe the data being transmitted over their networks at a microscopic level. Wireshark can be used to troubleshoot network issues, examine security problems, verify network applications, and learn network protocol internals. Its utility in understanding and diagnosing network behaviors makes it an important tool for network professionals.
- Wiretapping The act of covertly monitoring and recording telephone and internet conversations. This can be done either through physical access to the communication wires or remotely through software exploits. While often associated with unlawful surveillance and espionage, wiretapping is also used lawfully, under strict regulation, for purposes such as criminal investigations or intelligence gathering. Regardless of intent, wiretapping poses significant privacy concerns and is typically subject to rigorous legal constraints.
- Witness In the context of legal proceedings, a witness is an individual who, either voluntarily or under compulsion, provides testimonial evidence about what they observed or experienced. Witnesses can offer crucial information that may decide the outcome of a trial.
- Work Breakdown Structure (WBS)A tool used in project management that represents a hierarchical decomposition of a project into manageable components or tasks. In the context of a security project, the WBS might include tasks like threat modeling, security requirements analysis, and system hardening, each of which could be further broken down into more specific tasks. The WBS aids in tracking project progress, managing dependencies, and assigning resources.
