Intrusion detection system. An intrusion detection system ( IDS) is a device or software application that monitors a network or systems for malicious activity or policy violations. [ 1] Any intrusion activity or violation is typically either reported to an administrator or collected centrally using a security information and event management ...
Electronic countermeasure. Inspecting an AN/ALQ-184 Electronic Attack Pod. An electronic countermeasure ( ECM) is an electrical or electronic device designed to trick or deceive radar, sonar, or other detection systems, like infrared (IR) or lasers. It may be used both offensively and defensively to deny targeting information to an enemy.
In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current.
A host-based intrusion detection system ( HIDS) is an intrusion detection system that is capable of monitoring and analyzing the internals of a computing system as well as the network packets on its network interfaces, similar to the way a network-based intrusion detection system (NIDS) operates. [1] HIDS focuses on more granular and internal ...
A fence-mounted perimeter intrusion detection system installed on a chain link fence. A perimeter intrusion detection system ( PIDS) is a device or sensor that detects the presence of an intruder attempting to breach the physical perimeter of a property, building, or other secured area. [1] [2] A PIDS is typically deployed as part of an overall ...
Early warning satellite. Artist's rendering of a US DSP phase III satellite. An early warning satellite is a satellite designed to rapidly identify ballistic missile launches and thus enable defensive military action. This type of satellite was developed during the Cold War and later became a component of missile defense systems.
The AN/FPS-17 Detection Radar at the Shemya AFB became operational in May 1960, and the AN/FPS-80 Tracking Radar became operational on April 1, 1962. Blue Nine refers to the project which produced the AN/FPS-79 Tracking Radar Set built by General Electric, used with the Air Force 466L Electromagnetic Intelligence System (ELINT).
A reference designator unambiguously identifies the location of a component within an electrical schematic or on a printed circuit board. The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15. The number is sometimes followed by a letter, indicating that components are grouped or matched with ...
