Dependency injection in Python: a guide to testability and security boundaries

FastAPI shipped a built-in DI container in its very first release in December 2018 — but the same swappability that makes DI testable can quietly ship a mock into production.

Defense-in-depth for a modern cloud-native application stack

Log4Shell and the XZ backdoor were caught two different ways — one by patching, one by a developer noticing 500ms of extra SSH latency. Neither alone is a strategy.

Data loss prevention for developers: stopping leaks before they hit the network

CWE-532 covers secrets logged in plaintext — the exact bug that led Twitter to reset every password on May 3, 2018. Network DLP can't catch it; your code has to.

Why AI-generated code needs DAST, not just SAST

Copilot-generated code carried vulnerabilities in ~40% of cases in a 2021 NYU study. Static scanning alone cannot catch the runtime-only bug classes LLMs introduce.

CVSS 4.0 vs. 3.1: what actually changed, and why your priority list should too

CVSS 4.0 killed the Scope metric, added Attack Requirements, and split scoring into CVSS-B/BT/BE/BTE labels — here's what that means for triage.
