Security testing guides — vulnerability scanning, penetration testing basics, and secure SDLC practices.
Security Testing
FedRAMP (Federal Risk and Authorization Management Program) is the U.S. federal government's standard for cloud service security. If your product serves federal agencies, FedRAMP authorization is required. The security testing requirements are among the most rigorous in any compliance framework — and a significant portion can be automated.

Since its launch in 2016, Google's OSS-Fuzz program has found over 10,000 vulnerabilities and bugs in more than 1,000 open source projects. It runs fuzzing continuously, 24 hours a day, across billions of CPU-core-hours of compute. When it finds a crash, it automatically

Java has a reputation for safety — garbage collection eliminates entire classes of memory bugs, strong typing prevents many type errors, and the JVM sandboxes execution. But Java applications can still have serious bugs: path traversal vulnerabilities in file handling, deserialization exploits, XML/JSON parsing crashes, SQL injection through improperly sanitized

OSS-Fuzz handles the hosting and infrastructure for open source projects. But what runs underneath OSS-Fuzz? The answer is ClusterFuzz — Google's distributed fuzzing platform that scales across thousands of machines, automatically manages corpora, deduplicates crashes, minimizes test cases, and integrates with bug trackers. ClusterFuzz is open source

Rust's ownership system and borrow checker eliminate entire categories of memory safety bugs at compile time — but they cannot prevent all bugs. Logic errors, integer overflows (in release mode), incorrect invariant assumptions, panics on unexpected input, and subtle algorithmic mistakes are all still possible. cargo-fuzz brings libFuzzer&

Python's dynamic type system and exception handling make it easier to write code that handles invalid input gracefully — in theory. In practice, Python libraries that parse formats, process untrusted data, or call into native extensions can crash, hang, or exhibit undefined behavior just like C code. Atheris brings

Role-based access control (RBAC) bugs are subtle and expensive. A viewer who can delete records, an admin whose permissions don't cascade to subresources, or a billing role that can access user PII — these bugs are invisible until someone exploits them. This guide shows how to build a

Tenant isolation is the most critical security property of a multi-tenant SaaS application. A bug that allows Tenant A to read Tenant B's data is a catastrophic breach — and it's the kind of bug that standard happy-path tests never catch. This guide covers how
Snyk
Snyk scans your dependencies, container images, infrastructure-as-code, and source code for vulnerabilities and license violations. This guide covers CLI integration for Node.js and Python, pull request checks in GitHub Actions, container image scanning, and managing false positives with policy files. Key Takeaways Snyk finds vulnerabilities in transitive
Semgrep
Semgrep is a fast, syntax-aware static analysis tool that lets you write custom security rules in YAML using code patterns rather than regular expressions. This guide covers rule syntax, writing custom rules for your codebase, using community rulesets, CI integration, and reducing false positives through triage and rule refinement.
OWASP ZAP
OWASP ZAP is the most widely used open-source web application security scanner. This guide covers integrating ZAP's Docker-based full scan and API scanning into GitHub Actions CI/CD pipelines, configuring authentication for authenticated scans, and handling alert triage to keep pipelines actionable. Key Takeaways Run ZAP
Nuclei
Nuclei is a fast, template-driven vulnerability scanner that lets teams define custom checks in YAML and run them reproducibly against targets. This guide covers template syntax, writing custom templates for application-specific vulnerabilities, CI integration for regression testing, and responsible scanning and disclosure practices. Key Takeaways Nuclei templates are
