Canonical Definition
Runtime Security maintains system controllability through detection and dynamic response.
Three Design Principles of Runtime Security
Detection-Driven Approach
Response starts from detection. Optimize precision and speed. Acknowledge detection gaps and coordinate with Runtime Immunity to cover what detection cannot guarantee.
Dynamic Control and Constraint
After detection, constrain attack behavior without halting overall system operation — through isolation, restriction, and blocking.
Real-Time Responsiveness
Minimize time from detection to response. Shorter latency reduces the success probability and damage scale of attacks.
Positioning Within Runtime Stability
Runtime Security is detection-based protection within the Runtime Stability framework. It plays a primary role in Safety, Availability, and Controllability; and contributes to Inexploitability through dynamic elimination, which requires coordination with Runtime Immunity for high Inexploitability levels.
Implementation Forms
eBPF/kprobes/uprobes and related kernel instrumentation.
Security logic executing within the application process.
Runtime protection for workloads across cloud and hybrid environments.
Continuous monitoring and response capabilities at the endpoint.
Achievement Evaluation Framework
Runtime Security Level (SL) is evaluated by three axes: Recall, Precision, and Response Latency.
Full Formal Definition
Runtime Security: A technical system that detects attacks, anomalies, and unauthorized activities in real time during the state in which a processor executes its instruction set and data is loaded into memory (runtime), maintaining the system's Controllability.
