Security Stack Engineering (SSE)

A reference implementation of the Security Stack Engineering (SSE) architecture, a multi-algorithm system for governed security operations. The concept and architecture are authored by Thor Thor (codethor0).

This repository provides a proof-of-concept implementation with nine cooperating layers (L0–L8) that form a governed, measurable security system. The design may be subject to future patent filings; please consult the repository owner for licensing or commercial use questions.

Documentation: Substack Article

Architecture Overview

SSE splits security operations into nine algorithms, each with explicit inputs, outputs, and invariants:

Layer	Name	Language	Description
L0	Govern & Strategy	Go	GovernanceToken, risk register, objectives, target metrics
L1	Asset & Attack Surface	Python	EnvironmentSnapshot, asset gaps
L2	Identity & Access	Go	IdentityGraph, zero trust policies
L3	Telemetry & Data Fabric	Python	NormalizedEvent, TelemetryView, TelemetryGap
L4	Adversary Simulation (RTE-A)	Go	OffensivePlan, OffensiveFindings, signed tasks
L5	Detection & Analytics	Python	DetectionRule, Alert, CoverageMatrix
L6	Response & Orchestration	Go	Incident, Playbook, ResponseAction
L7	Engineering & Hardening	Python	EngineeringChange, HardeningProgress
L8	Assurance & Audit	Go	AssuranceReport, Attestation, GovernanceFeedback

Layers communicate via a shared message bus with typed topics and JSON schemas.

Adoption Pathways

Pathway A (Minimum Viable): L0 + L4 + L5 + L8. Governed adversary simulation with detection bridge and audit trail. No Python required.

Pathway B (Core Defense): Pathway A + L2 (Identity) + L6 (Response). Adds zero trust engine and incident response orchestration. L1/L3 stubbed via environment snapshot.

Pathway C (Full Stack): Same as Pathway B. Python layers (L1, L3, L5, L7) run standalone with MockBus via scripts/run_python_demo.sh.

Quick Start

Prerequisites

• Go 1.21+
• Python 3.11+
• (Optional) Python virtual environment

Pathway A (L0, L4, L5, L8)

./scripts/run_pathway_a.sh

Or manually:

go run ./cmd/orchestrator/main.go -pathway=a

Pathway B (adds L2, L6)

./scripts/run_pathway_b.sh

Pathway C (full L0–L8)

./scripts/run_pathway_c.sh

Hello World Scenario

A minimal end-to-end flow demonstrates:

1. L0 produces a GovernanceToken with one objective ("contain credential abuse within 15 min")
2. L4 runs an RTE-A engagement with one technique (T1078) and one signed task
3. L5 listens for offensive plans and emits a detection when the task executes
4. L8 generates an assurance summary with evidence and posture metrics

See examples/minimal_pathway_a/ for configuration and docs/architecture.md for message flow.
