Security

This category collects articles on securing web applications, servers, and the developer toolchain. Pieces here range from hands-on configuration walkthroughs to analysis of real-world vulnerabilities, covering both the defensive measures developers implement and the attack patterns worth understanding.

Authentication, authorization, and identity

A recurring thread in this collection is the practical side of access control - how authentication schemes like OAuth 2.0 and OpenID Connect work under the hood, where implementations tend to go wrong, and what correct token handling looks like in production. Articles in this group go beyond the happy path, examining edge cases, misconfiguration risks, and the tradeoffs between convenience and security posture.

Vulnerability classes and how they surface

Several pieces focus on specific vulnerability categories - SQL injection, cross-site scripting, insecure direct object references, and others catalogued in resources like the OWASP Top 10. These articles explain how each class of issue arises in real codebases, what the exploit looks like in practice, and what remediation actually requires. The goal is technical clarity, not a checklist.

Hardening, headers, and transport security

Another angle covered here is the configuration layer: HTTP security headers such as Content-Security-Policy and Strict-Transport-Security, TLS certificate management, and server-level hardening decisions that affect the attack surface of a deployed application. Articles in this group tend to be precise and environment-specific, addressing the gap between knowing a header exists and understanding when and how to tune it.
