In December 2020, attackers inserted a backdoor into a SolarWinds software update. In 2022, a malicious package mimicking a popular npm library was downloaded 300,000 times before removal. In 2024, the XZ Utils backdoor was only caught by accident. The pattern is consistent: software supply chain attacks work by

Container security scanning finds known vulnerabilities (CVEs) in your image's base OS packages and language dependencies before you ship them to production. Trivy is the most widely used scanner — it's fast, accurate, covers OS packages and application dependencies, and integrates with every major CI platform. This

A misconfigured S3 bucket. An RDS instance without encryption. A security group open to 0.0.0.0/0. These are the infrastructure mistakes that make headlines. Policy-as-code tools like Checkov and Terrascan catch them at write time — before terraform apply ever runs. This guide explains how both

NIST finalized its post-quantum cryptography standards in 2024: FIPS 203 (ML-KEM, based on CRYSTALS-Kyber), FIPS 204 (ML-DSA, based on CRYSTALS-Dilithium), and FIPS 205 (SLH-DSA, based on SPHINCS+). If you're running any system that encrypts data with RSA or ECDH, or signs with

Penetration testing is the practice of deliberately attacking your own system to find vulnerabilities before attackers do. For web applications, this means systematically probing every input, every endpoint, and every authentication mechanism to find what breaks. This guide covers the full pentest lifecycle for web apps — from reconnaissance through reporting

Azure Key Vault centralizes secret management, certificate storage, and cryptographic key operations. Testing applications that depend on Key Vault requires careful strategy: you don't want to skip Key Vault in tests (then you're not testing real behavior) but you also can't hardcode production secrets.

Payment Card Industry Data Security Standard (PCI-DSS) is the compliance framework that governs how organizations handle cardholder data. Version 4.0, which became mandatory in March 2024, brings significant changes that directly affect how development teams write, test, and deploy code. If your application touches payment card data — even

The OWASP Top 10 is the most referenced list in web application security. Published by the Open Web Application Security Project, it represents the ten most critical security risks based on data from thousands of real-world applications. This checklist gives you concrete tests for each category — not just definitions,
Testing
Manual penetration testing finds vulnerabilities — but it happens quarterly, or when someone remembers to schedule it. Meanwhile, your pipeline deploys new code every day. Automated security testing in CI catches vulnerabilities at the moment they're introduced — when the developer who wrote the code is still context-switched into
Testing
APIs are where most modern application logic lives — and where most security vulnerabilities occur. REST APIs, GraphQL endpoints, and WebSocket connections are all attack surfaces that need explicit security testing. Postman is a tool most developers and QA engineers already have. Beyond basic functional testing, it's surprisingly capable
Testing
GraphQL's flexibility is a double-edged sword. The same feature that lets clients fetch exactly what they need also lets an attacker craft a query that brings your server to its knees. The same resolver pattern that makes GraphQL elegant also creates N+1 query problems at scale.

Using production data in test environments is one of the most common compliance violations in software engineering — and one of the easiest to prevent. Test data masking and anonymization are the tools that let your QA team work with realistic data while keeping regulators and auditors satisfied. This guide explains
