The security industry spent thirty years teaching developers not to trust user input. Sound advice. Then handed them systems that trust everything — documents, task descriptions, tool schemas, fetched web pages, CI logs — provided the data arrives over an authorized channel. Here is where classical SAMM ends and the problem begins.
We release Agentic SAMM (ASAMM) v0.1.0, a framework extending OWASP SAMM to cover the assurance surface that begins where code ends.
What the paper contributes:
A threat taxonomy organized by entry point rather than consequence. Four primary threat classes (context injection, tool abuse, autonomy window exploitation, supply chain extension), two cross-cutting weakness overlays, three ecosystem modifiers. The taxonomy is stable across minor versions; the threat model it describes is explicitly not.
A two-axis trust model adapted from NATO STANAG 2511, applied uniformly to agents, tools, MCP servers, and context sources. Enforcement semantics are defined: A1 permits execution, F6 permits sandboxed execution only, with degradation on incident.
17 controls across five SAMM functions, with L1/L2/L3 maturity levels defined by evidence criteria rather than process compliance. Mapping to NIST AI RMF, NCSC Secure AI Guidelines, and GOST R 56939–2024.
Two implementation paths: migration from an existing SAMM-based program — including a section on inherited false positives, controls that remain green while the actual exposure goes undetected — and greenfield deployment.
The paper also names what it does not cover: systems without tool-calling agents, deterministic pipelines, LLMs used as autocomplete. A framework that cannot say no is not a framework.
