Mocking APIs for secure testing: MSW and json-server for error and auth flows

MSW intercepts requests at the network layer; json-server spins up a fake REST API in one command. Neither should ever touch a real backend or real credentials.

Minimal container images with ko: evaluating distroless Go builds

ko builds Go containers straight from source onto a shell-less distroless base with no Dockerfile — cutting attack surface, and debugging tools, at once.

Fuzz testing for AppSec teams: AFL++, libFuzzer, and OSS-Fuzz

OSS-Fuzz has found over 13,000 vulnerabilities since 2016, yet most AppSec teams still treat fuzzing as a research curiosity rather than a pipeline stage.
