IAST vs RASP: Runtime Protection Approaches Compared
Interactive Application Security Testing and Runtime Application Self-Protection both operate at runtime, but they serve different purposes. Here is how they compare and when to use each.
How to implement OAuth 2.0 securely
A step-by-step guide to implementing OAuth 2.0 securely: PKCE, redirect URI validation, token storage, and the vulnerabilities to avoid.
How to set up API rate limiting
A practical, step-by-step guide to setting up API rate limiting — gateway and app-layer configs, algorithm choices, per-endpoint tuning, and how to verify it actually blocks abuse.
API Gateway Security Patterns That Actually Work
API gateways sit between the internet and your services. Getting the security patterns right here multiplies your defense across every API behind them.
WAF Bypass Techniques and What They Mean for Supply Chain Security
Web Application Firewalls are a critical defense layer, but they are routinely bypassed. Understanding bypass techniques helps you build defense in depth rather than relying on a single control.
Deserialization Attacks in Java and Python
Insecure deserialization turns data parsing into code execution. This guide covers deserialization attacks in Java and Python, the gadget chain concept, and practical defenses for both ecosystems.
Security Considerations When Migrating from Monolith to Microservices
Decomposing a monolith into microservices changes the attack surface fundamentally. The security model that worked for the monolith will not work for the distributed system.
OAuth Token Security Throughout the Lifecycle
OAuth tokens grant access to APIs, services, and user data. Their security across creation, storage, use, and revocation determines your application risk posture.
Java Module System Security Features: What JPMS Actually Delivers
The Java Platform Module System promised stronger encapsulation and security boundaries. Here is what it actually delivers and where the gaps remain.
What is Static Code Analysis
Static code analysis scans source code for flaws before it runs. Here's how SAST works, what it catches, and where it falls short without reachability context.
What is Dynamic Code Analysis
Dynamic code analysis tests running applications to catch exploitable vulnerabilities that static scans and manifest files alone can easily miss.
React Native Security Considerations for Mobile Supply Chains
React Native introduces unique security challenges at the intersection of JavaScript and native mobile code. Understanding these risks is essential for securing cross-platform mobile applications.
