Network detection and response (NDR) refers to a category of network security products that detect abnormal system behaviors by continuously analyzing network traffic. NDR solutions apply behavioral analytics to inspect raw network packets and metadata for both internal (east-west) and external (north-south) network communications.
A minimum detectable signal is a signal at the input of a system whose power allows it to be detected over the background electronic noise of the detector system. It can alternately be defined as a signal that produces a signal-to-noise ratio of a given value m at the output. In practice, m is usually chosen to be greater than unity.
Vectra AI, formerly known as TraceVector, was founded in 2008 by a group of 4 cybersecurity professionals. Its mission was to offer security professionals an automated intrusion detection system that could address the escalating and sophisticated cyber-attacks which had increased dramatically in recent years.
Bundestag approved the development and procurement of three auxiliary ships as well as a training and reference reconnaissance facility (ARAA) for sea-based signal detection reconnaissance (ssA). As the main contractor, NVL was commissioned to develop the systems by February 2023. All services should be completed by 2029.
The XDR solution monitors the malware detection and antivirus capabilities of the endpoint detection and response (EDR) system and many extra cyber log sources to create greater context for Security Operations Center teams to perform faster threat detection, investigation and response. XDR improves on the EDR capabilities to deploy high-grade ...
Detection theory or signal detection theory is a means to measure the ability to differentiate between information-bearing patterns (called stimulus in living organisms, signal in machines) and random patterns that distract from the information (called noise, consisting of background stimuli and random activity of the detection machine and of the nervous system of the operator).
The typical airborne RWR system consists of multiple wideband antennas placed around the aircraft which receive the radar signals. The receiver periodically scans across the frequency band and determines various parameters of the received signals, like frequency, signal shape, direction of arrival, pulse repetition frequency, etc.
A cognitive radio (CR) is a radio that can be programmed and configured dynamically to use the best channels in its vicinity to avoid user interference and congestion. Such a radio automatically detects available channels, then accordingly changes its transmission or reception parameters to allow more concurrent wireless communications in a given band at one location.
