What are the main components of an intrusion detection system (IDS)?

• A. Firewalls, routers, and switches
• B. Sensors, management server, and user interface
• C. Encryption, authentication, and logging
• D. Data storage, routing, and analysis

Answer: (B)

An intrusion detection system (IDS) is primarily focused on monitoring network traffic for suspicious activities and potential threats. The main components of an IDS include sensors, which are responsible for collecting data from the network or host systems to detect any malicious activities. The management server processes the data received from these sensors, analyzing signs of intrusion and taking notes of any actionable threats. Finally, the user interface allows operators and security analysts to interact with the IDS, view reports, and manage the system effectively. Understanding this architecture is crucial because it highlights how the IDS operates as a cohesive unit that relies on each component to fulfill its purpose of threat detection and response. Components such as firewalls, routers, and switches, while important in network security, do not specifically pertain to the IDS function. Similarly, encryption, authentication, and logging, while relevant for overall security, are not integral parts of the IDS framework itself. The focus on data storage, routing, and analysis in other options reflects general network management and security practices rather than the specific structure and operational workflow of an IDS.
