[Verse 1] Before your app meets the world outside Static scanning reads each line you've typed No execution, just examination SAST finds flaws in preparation Buffer overflows and injection gates SQL commands that manipulate Catch the danger while it sleeps in code Before deployment hits the road [Chorus] SAST sees the source, DAST tests the running IAST watches while the gears are humming Static, Dynamic, Interactive too Three guardians protecting what you do Scan the written, probe the live Monitor what users give Security woven through your pipe Every stage, every type [Verse 2] Dynamic testing strikes while systems breathe DAST attacks what browsers receive Black box probing from the outside in Testing endpoints where hackers begin Cross-site scripting, authentication breaks Real-time scanning for security's sake Production mirrors feel the pressure test While your application gives its best [Chorus] SAST sees the source, DAST tests the running IAST watches while the gears are humming Static, Dynamic, Interactive too Three guardians protecting what you do Scan the written, probe the live Monitor what users give Security woven through your pipe Every stage, every type [Bridge] IAST combines the best of both worlds Inside the runtime, watching data swirl Sensors planted in the beating heart Real user flows tear weak spots apart Early phases need the static eye Runtime testing when the code can fly Continuous watching through each deploy Three methods that you should employ [Verse 3] Pipeline integration, that's the key Shift security left strategically Developers fix what static tools reveal Dynamic testing makes the threats more real Interactive scanning never sleeps Monitoring production's hidden deeps Together they form a triple shield No single point where defenses yield [Outro] Static early, dynamic later Interactive as your investigator SAST, DAST, IAST align Security by thoughtful design
