Runtime integrity is the assurance that code and process behavior remain trustworthy during execution rather than only at startup or install time. It matters because trusted software can still be altered or abused after launch if runtime protections are weak.
What is Runtime Integrity?
Runtime integrity focuses on tampering, injected code, altered memory, policy bypass, and other signs that a process is no longer behaving as intended. It matters for high-risk endpoints, sensitive apps, and detection of post-launch compromise.
What Runtime Integrity Commonly Supports
Common uses include anti-tamper controls, EDR analytics, process monitoring, protected app execution, and malware detection.
Runtime Integrity vs. Static Integrity Check Only
Runtime integrity continues evaluating trust while the code is running. Static checks only validate earlier states such as install or launch.
Frequently Asked Questions
Why is runtime integrity important?
Because attackers often wait until software is already trusted and running before they manipulate it.
Can code signing guarantee runtime integrity?
No. Signing helps before execution, but runtime compromise can still happen afterward.
