SAST
Application Security / DevSecOps
Simple
SAST is a building block of "Application Security / DevSecOps". In plain terms: threat modeling, sast, dast, sca, secrets scanning and secure ci/cd. This topic focuses specifically on sast and the core ideas you need to understand it.
Technical
Technically, SAST involves the mechanisms, data structures and protocols that underpin application security / devsecops. You will study how it is implemented, how it is configured, how it fails, and how its behavior shows up in logs, traffic or code.
Why it matters
Fixing flaws in design is far cheaper than fixing them in production.
Example
In a real organization, professionals working in appsec engineer, devsecops engineer. rely on sast to make decisions — for example, explaining an alert, hardening a system, or writing a finding in a report.
Practice idea
Build a small lab in a VM and experiment with sast using the related tools below. Document what you observe.
Deep dive
Read the official documentation and relevant RFCs/standards for SAST. Explore edge cases, internals, and how attackers and defenders view it differently.
