Authentication & Security · Development
Programming languages, patterns, and development practices
How AWS Dogwood adds temporal conditions to Cedar policies, lowers them back to plain Cedar, and enforces agent guardrails at the Amazon Bedrock AgentCore gateway.
How Zapier MCP gives AI agents action-level whitelisting, credential isolation, and human-in-the-loop approval, a managed alternative to custom scoped proxies.
A vendor-neutral evaluation of AWS Verified Permissions, SpiceDB, OpenFGA, Cerbos, and OPA, with architecture patterns, cost analysis, and a decision framework.
A deep comparison of Cedar, Rego, OpenFGA DSL, and Cerbos YAML/CEL policy languages: syntax, performance, formal verification, tooling, and TypeScript integration.
A deep technical comparison of SpiceDB and Auth0 FGA (OpenFGA), two Zanzibar-inspired systems with different trade-offs in schema, consistency, deployment, and scale.
Authentication vs authorization, common permission pitfalls, the fail-closed principle, and the goals every permission system should meet.
Refactor scattered permission checks into a centralized service layer, add Next.js middleware guards, and build a defense-in-depth authorization architecture.
Build a type-safe RBAC system in TypeScript, create a unified can() function, sync permissions across UI and backend, and learn when RBAC reaches its limits.
Build an ABAC policy engine in TypeScript with the builder pattern, conditional permissions, and type-safe policy evaluation that replaces RBAC's limitations.
Extend ABAC with environment-based rules, field-level read and write permissions, and automatic database query filtering that eliminates duplicate permission logic.
Add multi-tenant isolation to your permission system, evaluate CASL as a library alternative, and use decision frameworks to choose the right authorization architecture.
Securing AI agents in production with AWS Bedrock Guardrails, defense-in-depth, and patterns that prevent prompt injection, tool misuse, and multi-agent attacks.
A deep dive into security risks, trust building, and governance for AI developer tools, with real incident response strategies and shadow AI management.
A comprehensive security reference with implementation context, lessons learned, and practical guidance from production systems.
Working across many industries shows one-size-fits-all auth is a myth; each business domain shapes your authentication architecture differently.
Where AI-assisted code review catches what humans miss, where humans still excel, and how to build effective human-AI collaboration in your review process.
Compare Auth0, Firebase Auth, Supabase Auth, AWS Cognito, and custom solutions: when to use each, cost trade-offs, and lessons from production debugging.
A step-by-step guide to secure session management in production React Native apps with Auth0, biometric authentication, and proper token lifecycle handling.
