How to Secure AI Agents, MCP Servers, and LLM Apps in Production

AI agents, MCP servers, and LLM apps break the core AppSec assumption that applications do what their code says.

This guide walks through a practical see-fix-protect framework: a five-layer agentic AI attack surface map, a 12-point misconfiguration checklist, an evidence-based triage matrix, runtime guardrails, and system prompt hardening — plus a maturity self-assessment aligned to NIST AI RMF, OWASP AIMA, ISO/IEC 42001, and the EU AI Act.
