Deep dives, practical guides, and incident analyses from engineers who build Safeguard. No fluff, no vendor FUD — just what you need to ship secure software.
A git submodule stores a commit pointer, not files, so the superproject commit records the exact library version. How to use it for firmware releases.
Steps to add sha256 hashes to a pinned requirements file, turn on pip hash checking, and cope with platforms that have several files per package.
An application locks versions in Gemfile.lock. A gem cannot, since Bundler ignores a gem's own lockfile when resolving. What that means for risk.
A decision guide for choosing between fuzzing and property-based testing: what each needs, what each finds, and when to use both on the same code.
How to add fuzzing to CI without slowing every build: corpus replay on each commit, a bounded run on pull requests, and longer batch runs on a schedule.
How to schedule fuzzing: replay the corpus on every pull request, run time-boxed fuzzing nightly, and keep a long running job for critical parsers.
Atheris brings libFuzzer to Python. Set up a harness, instrument imports, and pair it with sanitizers when you test native extension modules.
Jazzer is a coverage-guided fuzzer for the JVM. Add a FuzzTest method, run in regression mode by default, and switch fuzzing on when you want a hunt.
Rust is memory safe, but unsafe code, panics and logic bugs still need fuzzing. Install cargo-fuzz, add a target, run it, then minimize what it finds.
