Runtime augmentation refers to the enhancement of a system’s security by dynamically adding or modifying security controls while the system is running. This approach enables real-time, adaptive responses to emerging threats, vulnerabilities, or anomalous behaviors as they occur, rather than relying solely on pre-configured, static defenses. Techniques can include injecting monitoring code, altering permissions, or deploying patches without downtime. Runtime augmentation helps organizations maintain resilience against evolving cyber threats by providing flexible, immediate protection and minimizing the window of exposure to attacks.
