Liveness

Liveness refers to the ability of a system, such as a computer network or application, to continuously provide responses or perform its functions without unnecessary interruption. It ensures that the system remains operational, responsive, and ready to handle requests in real-time or within acceptable timeframes. In cybersecurity, liveness checks are used to verify that a user or device is genuinely present and active, preventing fake or malicious entities from gaining access. Overall, liveness indicates that a system is active, reliable, and able to serve its intended purpose effectively.
