Runtime Software Verification

Runtime software verification is the process of validating the integrity, behavior, and security posture of software while it is actively running in production or pre-production environments. Unlike static testing or pre-deployment checks, runtime verification continuously monitors how software behaves under real-world conditions to detect anomalies, unauthorized changes, or malicious activity.

It ensures that deployed applications remain trustworthy and compliant throughout their operational lifecycle.

Even after rigorous pre-deployment testing, software can be compromised at runtime due to:

• Configuration drift
• Insider threats
• Supply chain tampering
• Runtime exploitation or memory manipulation

Runtime verification:

• Detects deviations from expected behavior
• Identifies attacks or breaches in real time
• Validates that only authorized code is executing
• Provides ongoing assurance of software integrity

This is especially critical in regulated environments, Zero Trust architectures, and for mission-critical software systems.

Runtime verification typically involves:

• Behavior Monitoring: Tracks file system access, memory usage, system calls, network activity, and inter-process communications
• Hash and Signature Validation: Ensures code running in memory matches approved versions or signatures
• Memory and Process Inspection: Detects injections, unauthorized libraries, or altered binaries
