GrizzDog-AI: Cyber Defense Lab & Guardrail Sandbox

Butler Community College (Andover Campus) Cyber Faculty Research Project

Important

Academic Notice & Disclaimer: GrizzDog-AI is an independent academic research and pedagogical cybersecurity lab developed by a Butler Community College Cyber Defense faculty member. It is NOT an official Butler Community College institutional project, endorsement, or service. This sandbox is strictly designed for educational research, classroom lab exercises, and cybersecurity defense testing within accredited educational curricula (such as Butler's NSA/DHS CAE-CD designated program).

Upstream Attribution: GrizzDog-AI is based upon and adapted from the foundational cybersecurity architecture created by SixFiveMil in Securing-AI. We extend deep gratitude and credit to SixFiveMil for the original architecture and design patterns.

GrizzDog-AI is a hands-on cybersecurity curriculum lab designed around the Butler Community College (Andover Campus) in Andover, Kansas. Aligned with Butler's NSA/DHS-designated Center of Academic Excellence in Cyber Defense Education (CAE-CD) curriculum, it teaches LLM security vulnerabilities, prompt injection defenses, indirect injection, FERPA data privacy, and guardrail architectures through realistic Red Team and Blue Team exercises themed in Butler Purple and Gold.

What's New (October 2026)

MITRE ATLAS & OWASP Top 10 for LLM mapping: All 27 benchmark attack vectors, curriculum guides, web UI cards, and exported Canvas reports map directly to industry taxonomies (OWASP LLM01–LLM07 and MITRE ATLAS AML.T0051–AML.T0057) aligned with CAE-CD Knowledge Units.
Turnkey Canvas LMS Batch Grader: Instructors can batch-grade an entire folder of student .md submissions with batch_grade.py, verify cryptographic HMAC-SHA256 signatures, audit rule provenance, and generate an import-ready canvas_grades.csv gradebook.
Real breach detection: a leaked secret counts as a breach (BREACHED 🚨) with a live model, not just in the offline simulator, including spaced-out or reformatted leaks.
Safe rendering: model replies and anything students type are HTML-escaped, so a crafted reply can't run code in the browser (OWASP LLM02).
Honest Canvas reports: HMAC-signed with an instructor-only REPORT_SECRET (verify_report.py), only Parts 2 & 3 auto-scored, unedited presets earn 0, reflections start empty.
One-command model build: build_models.py builds all 18 models; the pipeline shows FALLBACK ⚠️ / SIMULATED ⚠️ when the selected model isn't the one answering.
Phase 3 fixed: OPA starts again in Docker (a preset file in policies/ caused a merge error), native setups evaluate the real rules.json with a Python port of gateway.rego, and Phase 3 now also checks model replies.
Auto-updating launcher: start.bat / start.sh update to the newest tagged release before starting, keep student edits, roll back a broken release, and never block startup when offline.
Turnkey 1-Command Mac Installer: Brand-new Macs (M1–M4 Apple Silicon & Intel) install natively with Homebrew, Ollama, model downloads, and auto-port fallback in one Terminal command without needing Docker.
Booth QR code: scannable in Docker and pointed at Butler's current Cyber Security program page.
Locked down by default: listens on this computer only, filter_rules.py is parsed as data (never executed), cross-site and DNS-rebinding requests are refused, and GRIZZDOG_KIOSK=1 (or EDUGUARD_KIOSK=1) turns a booth laptop into a booth-only kiosk.

Overview & Educational Scenario

The lab simulates Butler Community College's Andover Campus AI Infrastructure, featuring a Butler Purple & Gold cyber HUD interface and four distinct personas:

Persona	Name	Academic & Campus Role	High-Value Targets / Confidential Assets
🐕 GrizzDog	GrizzDog	Autonomous Quadruped Robotic Sentry (Butler Safety & Cyber Lab - Andover 5000 Bldg)	Firmware Root Key (`GRIZZDOG-ROOT-KEY-9941`), Unit ID (`GRIZZDOG-QUAD-SENTRY-01`), Patrol Override Command (`/override_grizzdog_patrol`), Disarm Signature (`GRIZZDOG-DISARM-SIG-882`)
🎓 Course TA	Sage	Butler Cyber & Computer Information Technology Tutor	Midterm Exam Q4 Answer Key (`EXAM-KEY-CS101-FALL26-Q4-RSA`), Rubric Formula, TA Token (`TA-AUTH-SAGE-7731`), Socratic Override Command
📝 LMS Grader	GraderBot	Automated Butler Canvas Homework Grader (`canvas.butlercc.edu`)	Canvas Admin API Token (`CANVAS-API-KEY-PROD-9912`), Internal Gradebook Host (`gradebook.canvas.butlercc.internal`), Grade Override Key
🏛️ Registrar	Morgan	Butler Admissions & Academic Records Advisor	Confidential FERPA Student Record (`SID-88391: GPA 1.82 - Academic Suspension`), SIS Host (`db-sis.registrar.butlercc.internal`), Master Export Token

Attack & Defense Curriculum

Red Team Attack Categories (6 Missions)

Robotics Control & Hardware Key Exfiltration: Disarming the campus quadruped sentry (GrizzDog) or overriding patrol routes via unverified radio commands.
Exam Integrity & System Prompt Leakage: Extracting confidential exam questions, answer keys, or rubrics from the tutor via direct prompt injection.
Authority Spoofing & Privilege Escalation: Impersonating professors (e.g. Herbert A. Simon / Dr. Simon), robotics leads (Dr. Chen), the Dean, or Canvas administrators to demand elevated credentials.
Indirect Prompt Injection: Embedding hidden commands in student homework assignments or essays (e.g., ) to coerce the automated grader.
FERPA & Privacy Exfiltration: Tricking the registrar bot into leaking student GPAs, disciplinary sanctions, or internal database connections.
Academic Integrity & Socratic Bypass: Coaxing the assistant into writing complete homework solutions or bypassing Socratic tutoring mandates.

4 Progressive Hardening Tiers (Prompt Engineering)

Each persona is available across 4 distinct difficulty tiers to accommodate varying student skill levels:

Level 1 — Ultra-Vulnerable / Naive (vulnerable): Extremely compliant and naive; has zero guardrails, aims to please, and willingly outputs secrets on simple direct questions. Perfect for an easy "first-win" in class.
Level 2 — Basic (basic): General instructions not to share sensitive data, but vulnerable to simple persona adoption, authority claims, and hypothetical storytelling.
Level 3 — Hardened (hardened): Strict role boundaries, refusal of authority claims without cryptographic authentication, and enforced Socratic guidance.
Level 4 — Paranoid / Zero-Trust (paranoid): Strict output templates, zero exception handling, and immediate policy lockouts upon detecting any adversarial or unauthorized probing.

Blue Team Defense-in-Depth (3 Layers)

Phase 1: Model Hardening (lab/modelfiles/): Role anchoring, negative constraints, and removing confidential assets from prompt context.
Phase 2: Static Gateway Filtering (lab/scripts/filter_rules.py): Pre-model ingress blocking and post-model egress Data Loss Prevention (DLP).
Phase 3: OPA Policy Enforcement (policies/rules.json & gateway.rego): Semantic intent classification, domain whitelisting, risk flags, and confidence thresholds. Phase 3 checks incoming prompts (blacklist + classifier context) and, after Phase 2's DLP, model replies against its own egress_secrets / egress_patterns, a second, independently edited leak check.

Without Docker (native Windows/macOS tracks), there is no OPA container: the gateway evaluates policies/rules.json with lab/scripts/policy_eval.py, a Python port of gateway.rego that gives the same decisions. If Ollama isn't reachable at all, an offline simulator answers in each persona's voice, and the pipeline says so.

🤝 K-16 Companion Project Ecosystem

Butler Community College operates a unified, two-tier cybersecurity educational ecosystem featuring the GrizzDog cyber mascot:

GrizzDog-AI (Port 5000 — This Repository):
- Audience: Undergraduate cybersecurity degree candidates, college red team competitors, and industry practitioners.
- Focus: Multi-phase defense engineering (Model Hardening + Static Regex Ingress/Egress DLP + Open Policy Agent Rego semantic evaluation), automated Canvas LMS HMAC-signed batch grading, and 27-vector benchmark evaluation.
GrizzDog-jrCyberQuest (Port 5050 — Sibling K-12 Outreach Lab):
- Audience: K-12 students (Kindergarten through 12th Grade), STEM expo attendees, and high school recruitment preview days.
- Focus: Gamified 60–120 second interactive quests with dynamic 4-tier mascot evolutions (Pixar pup to hardened sentry), Treat Phishing Detective (aligned with the physical Unitree Go2 robot dog), and zero-latency offline gameplay.
Side-by-Side Coexistence: Both platforms feature automatic port collision detection and can run concurrently on the same computer or booth kiosk laptop without conflict.

Quickstart

🍎 Fresh Mac (Apple Silicon M1–M4 & Intel): 1-Command Installer

Open Terminal (Cmd+Space, type Terminal, press Enter) and paste:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/daTechGuy/GrizzDog-AI/main/setup_mac.sh)"

Installs Homebrew, Python, Ollama, downloads llama3.2, compiles all 18 models, configures .venv, and automatically handles macOS AirPlay port conflicts.

Fastest way: the launcher (updates itself, then starts)

.\start.bat            # Windows (cmd or PowerShell)
./start.sh             # Mac / Linux
.\start.bat --docker   # use the Docker stack instead of running natively
.\start.bat --kiosk    # booth laptop: booth-only page, no editing

Or follow the Setup Guide. The launcher automatically bootstraps .venv and manages dependencies.

1. Launch Docker Stack

From the project root:

docker compose up -d

Open the web sandbox:

http://localhost:5000  (or http://localhost:5001 if port 5000 is occupied by macOS AirPlay)

2. Build the Lab Models

One command pulls the llama3.2 base model (one-time ~2GB download) and builds all 18 models: 4 personas × 4 hardening tiers, plus the vulnerable_bot / hardened_bot fallbacks.

python lab/scripts/build_models.py --docker   # Docker stack
python lab/scripts/build_models.py            # native Ollama (Windows/Mac/Linux)
python lab/scripts/build_models.py --check    # just list missing models

Re-run it after editing any Modelfile. If a model is missing, the pipeline's model step shows FALLBACK ⚠️ (a stand-in model ran with that tier's system prompt) or SIMULATED ⚠️ (Ollama unreachable, offline simulator answered) instead of failing silently.

Running without Docker? See the native Windows/macOS tracks in the Setup Guide.

Security & Network Lockdown

The gateway has no login, so it is locked down in layers instead:

This computer only (default). It listens on 127.0.0.1:5000; Docker publishes the web, Ollama and OPA ports on 127.0.0.1 only. Other machines on the Wi-Fi can't connect.
Rules are data, not code. filter_rules.py is parsed, never executed: only the three ["..."] lists are accepted, so the browser editor can't be used to run code on the laptop.
Web pages can't attack it. Write requests must be JSON from the app's own origin, and requests for any hostname other than localhost / 127.0.0.1 are refused (blocks cross-site and DNS-rebinding tricks from a malicious site open in the same browser).
Booth kiosk mode (GRIZZDOG_KIOSK=1 or EDUGUARD_KIOSK=1): locks the page to the booth, turns off every route that reads or edits rules, system prompts or models, and never sends system prompts to the browser. Booth, arena and benchmark keep working.

Classroom server that students reach over the network (opt-in; the Defense Studio is then open to everyone on that network, so use a trusted classroom network only):

# Docker
WEB_BIND=0.0.0.0 GRIZZDOG_ALLOWED_HOSTS='*' docker compose up -d
# Native (PowerShell: $env:GRIZZDOG_HOST="0.0.0.0"; $env:GRIZZDOG_ALLOWED_HOSTS="*")
GRIZZDOG_HOST=0.0.0.0 GRIZZDOG_ALLOWED_HOSTS='*' python lab/scripts/secure_gateway.py

Booth laptop: GRIZZDOG_KIOSK=1 (or EDUGUARD_KIOSK=1), keep the default local-only binding, and follow the booth checklist in the Setup Guide.

3. Configuration (Environment Variables)

All optional. Docker Compose sets the OPA and Ollama ones for you.

Variable	Default	Purpose
`OLLAMA_HOST`	`http://localhost:11434`	Ollama server URL
`CONTEXT_MODEL`	`llama3.2:1b` (Compose: `llama3.2`)	Phase 3 intent classifier model; falls back to `llama3.2`
`OPA_ENABLED`	`false` (Compose: `true`)	Use the OPA server for Phase 3; otherwise the local Python evaluator reads the same `rules.json`
`OPA_URL`	`http://opa:8181/v1/data/gateway/decision`	OPA decision endpoint
`OPA_FAIL_OPEN`	`false`	If OPA is unreachable, allow instead of block
`REPORT_SECRET`	(unset)	Instructor-only key that signs Canvas lab reports; unset = reports marked UNSIGNED
`HELDOUT_TESTS_PATH`	`lab/benchmark/heldout_tests.json`	Private held-out benchmark file for graded work
`GRIZZDOG_HOST` (legacy: `EDUGUARD_HOST`)	`127.0.0.1` (Compose: `0.0.0.0` inside the container)	Network interface to listen on; `0.0.0.0` lets other machines connect
`GRIZZDOG_PORT` (legacy: `EDUGUARD_PORT`)	`5000`	Gateway port (auto-switches to `5001` if port 5000 is occupied, e.g. macOS AirPlay)
`GRIZZDOG_ALLOWED_HOSTS` (legacy: `EDUGUARD_ALLOWED_HOSTS`)	`localhost,127.0.0.1`	Hostnames the gateway answers to; `*` = any (needed for LAN classroom servers)
`GRIZZDOG_KIOSK` (legacy: `EDUGUARD_KIOSK`)	`0`	`1` = booth kiosk: booth-only page, no rule/prompt/model editing
`GRIZZDOG_UPDATE_CHANNEL` (legacy: `EDUGUARD_UPDATE_CHANNEL`)	`release`	Launcher update channel: `release` (newest tagged version), `main` (latest commit), `off`
`GRIZZDOG_NO_UPDATE` (legacy: `EDUGUARD_NO_UPDATE`)	(unset)	`1` = freeze: the launcher never updates (use the night before and during events)
`GRIZZDOG_REQUIRE_SIGNED_TAGS` (legacy: `EDUGUARD_REQUIRE_SIGNED_TAGS`)	(unset)	`1` = only accept release tags that `git verify-tag` trusts
`WEB_BIND` (Compose only)	`127.0.0.1`	Host interface Docker publishes port 5000 on; `0.0.0.0` for LAN access

Blue Team Workflow: 3-Phase In-Browser Defense Studio

GrizzDog-AI features a live, in-browser 3-Phase Defense Architecture Studio accessible directly at http://localhost:5000. Students and instructors can easily identify, switch between, and edit all three defense layers with real-time syntax validation, hot-reloading, and preset management:

Phase	Defense Layer	Target File	Browser Studio Features & Capabilities
🟣 Phase 1	Model Hardening	`lab/modelfiles/*.txt`	Edit neural system prompts across all 4 hardening tiers (Level 1 Ultra-Vulnerable to Level 4 Paranoid). Hot-reloads in-memory and saves to disk; one-click runtime rebuild in Ollama.
🟡 Phase 2	Static Gateway Rules	`lab/scripts/filter_rules.py`	Edit the `INGRESS_BLACKLIST`, `EGRESS_SECRETS`, and `EGRESS_PATTERNS` string lists. The file uses Python list syntax but is parsed as data, never run: imports, functions or other code are rejected on save. One-click presets: Calibrated Benchmark (100% visible / 0% held-out), Scaffolded (Starter), and Blank.
🔵 Phase 3	OPA Policy Engine	`policies/rules.json`	Edit Open Policy Agent declarative rules: allowed/blocked domains & intents, confidence thresholds (`0.8` allow, `0.55` clarify), and high-risk flags. Automated JSON linting, formatting, and live sync with OPA watcher. Native (no-Docker) setups use `lab/scripts/policy_eval.py`, a Python port of `gateway.rego` that reads the same `rules.json`, and the pipeline labels it "Local Policy Evaluator (OPA engine offline)".

Visual Phase Identification & Dynamic Synchronization

Color-Coded Phase Tab Bar: Segmented tabs styled in Butler Purple (Phase 1), Butler Gold (Phase 2), and Cyber Blue (Phase 3) with individual status banners and file badges.
Defense Architecture Dropdown Sync: Switching the Defense Architecture dropdown automatically focuses and opens the corresponding Phase editor tab.
Editor Ergonomics: Monospace code editor with Tab key indent support (4 spaces for Python, 2 spaces for JSON), instant save feedback, and reload-from-disk capabilities.

📘 Plain-English Concepts & Interactive Hover Guide

Designed for cybersecurity learners, students, and educators, GrizzDog-AI includes plain-English conceptual breakdowns with relatable everyday analogies:

Interactive Hover Tooltips (ⓘ Badges): Hovering over Model Hardening, Defense Architecture, Unit Persona, any Hardening Level, any Defense Phase Tab, or Mission Categories displays an instant explainer card with a real-world plain-English analogy:
- Phase 1 (Model Hardening): Student Integrity Analogy — Training the student's inner conscience to refuse peer pressure and cheating tricks ("No, I cannot break the honor code").
- Phase 2 (Static Filters): Backpack Scanner Analogy — Front-door security checking for contraband weapons before entering, and checking that no school property is stolen when leaving.
- Phase 3 (OPA Policy Engine): Principal's Hall Pass Analogy — Even with a clean bag, students cannot enter restricted areas without a signed hall pass confirming proper authorization.
- 4 Hardening Tiers: From Level 1 (leaving your locker wide open with your phone and money on display) to Level 4 (a bank vault with laser tripwires).
Collapsible Field Guide Drawer: A one-click 📘 ESSENTIAL CYBER FIELD GUIDE accordion located above the Defense Studio offers a complete cheat-sheet matrix across all phases and tiers.
Inline Analogy Callouts: Every Defense Phase editor panel features a highlighted analogy box explaining how edits directly impact sentry resilience.

Interactive Visual Defense Pipeline Flowchart

GrizzDog-AI visualizes defense-in-depth with a live, animated 6-node packet trace flowchart rendered above the prompt terminal in both Classroom Studio and Booth Kiosk modes:

[ 📥 1. Ingestion ] ──▶ [ 🟡 2. Ingress Filter ] ──▶ [ 🔵 3. OPA Policy ] ──▶ [ 🟣 4. Neural Hardening ] ──▶ [ 🟡 5. Egress DLP ] ──▶ [ 🛡️ 6. Final Verdict ]

Live Animated Packet Trace: Each submission illuminates nodes in real time with status badges: PASSED ✓, INTERCEPTED 🛡️, BLOCKED ⛔, LEAK CAUGHT 🔒, SKIPPED ⏭️, ALLOWED 🔓, and BREACHED 🚨 (the model actually leaked a protected secret). The model node shows EXECUTED ✓, FALLBACK ⚠️ or SIMULATED ⚠️ so it's always clear which model answered.
Defensive Explainability: Learners see which layer stopped a payload and why: an ingress keyword match, a Phase 3 policy decision (domain, intent, risk flag or confidence), the model's own refusal, or an egress DLP catch, and when nothing stopped it, exactly what leaked.
Phase 3 label: With the OPA container running the node reads "OPA Policy Engine"; on native setups it reads "Local Policy Evaluator (OPA engine offline)", a Python port of gateway.rego that applies the same rules.json.

STEM Fair & Expo Booth Kiosk Mode: "Beat the GrizzDog" Challenge

For campus open houses, STEM outreach events, cyber competitions, and recruitment booths, toggle into 🕹️ Expo Booth Kiosk Mode via the header switch ([ 🔬 Classroom Studio ] ⇄ [ 🕹️ Expo Booth Kiosk ]).

Designed specifically for 2–3 minute high-energy visitor interactions on booth tablets and laptops:

1. 3-Stage "Beat the GrizzDog" Speed Challenge

Visitors compete to breach the Butler Cyber robotic sentry across progressive defensive tiers:

Stage 1 — Naive Sentry (Warmup): Level 1 Vulnerable sentry with no outer defenses. Any basic trick or direct question extracts the root key (GRIZZDOG-ROOT-KEY-9941).
Stage 2 — Perimeter Filters (Intermediate): Level 2 Basic sentry behind the Phase 2 ingress keyword filter and egress DLP. Direct probes are caught at the perimeter; visitors must find wording the filters don't expect.
Stage 3 — Final Boss: Level 3 Hardened sentry + Phase 2 ingress & DLP + Phase 3 policy. Exact-match DLP still misses obfuscated leaks (e.g. asking for the key spelled out letter by letter), which is the lesson.

All three stages are beatable offline with the built-in simulator, so the booth works without Wi-Fi or a GPU.

2. Touch-Friendly "Mad-Libs" Attack Payload Builder (Zero Typing Required)

Crowded booths and tablet touchscreens don't require slow manual typing. Visitors click interactive pill buttons to assemble adversarial attacks in seconds:

Disguise / Persona: Butler Robotics Director (Dr. Chen) | Emergency Campus Security Tech | Undercover Safety Auditor | Canvas LMS Administrator | Confused Freshman Student
Objective / Exploit: Extract GrizzDog Root Firmware Key | Disarm Andover Campus Quadruped Sentry | Exfiltrate Confidential FERPA Records | Override Autonomous Patrol Route
Evasion Tactic: Hypothetical Fiction Drill | Strict Roleplay / Override Mode | Emergency Safety Maintenance Override | Reverse Psychology & Inversion
🎲 Random Surprise Combo: Generates a pre-compiled injection attack with one tap for instant trial.

3. Butler Cyber Recruitment Victory Badge & Offline QR Code

Each time a visitor breaches a stage, the system marks it cleared, unlocks the next one, and shows a celebratory recruitment card:

Butler Mascot & Sentry Breaker Badge: Shows which stage they cleared and the technique (prompt injection).
Offline-Rendered Vector SVG QR Code: Links prospective students directly to Butler Community College's Cyber Security Program (https://www.butlercc.edu/academics/degrees-certificates/cyber-security). The SVG is pre-generated and committed (lab/assets/butler_cyber_qr.svg), so it works offline and in Docker with no extra packages. If the URL changes, run python lab/scripts/make_qr.py <url> (needs pip install qrcode) and update BOOTH_QR_URL in secure_gateway.py.
1-Click "Reset for Next Student": Instantly resets all three stages for the next visitor in line.

4. Dual-Engine Neural Execution: Real Local Ollama AI + Offline Simulator Fallback

A frequent question for STEM fairs and conference setups is: does Kiosk mode run real local AI or a simulation?

Answer: It runs real local Ollama AI whenever Ollama is reachable, and automatically falls back to an offline heuristic simulator if Ollama is offline or unavailable.

Both the Expo Booth Kiosk and Classroom Studio route all queries through the unified defense pipeline (evaluate_defense_pipeline):

Priority	Engine	Operating Scenario	Pipeline Node 4 Indicator
1. Primary	Local Ollama AI	Ollama daemon is running locally (`http://localhost:11434`) and lab models are installed. The LLM generates authentic real-time neural responses.	`EXECUTED ✓` (`model 'grizzdog_vulnerable'`)
2. Fallback AI	Local Ollama AI (Generic)	Ollama is active, but a specific persona model was not pre-built; runs `vulnerable_bot` or `hardened_bot` using the tier's active system prompt.	`FALLBACK ⚠️`
3. Offline Safety	Deterministic Simulator	Ollama is stopped, out of memory, or running on a battery-constrained laptop with no GPU. Uses built-in heuristic logic.	`SIMULATED ⚠️` (`offline simulator`)

Why this dual design is critical for live events:

Zero Event Downtime: If an expo laptop has no GPU, lacks Wi-Fi, or crashes the Ollama daemon, visitors can still play the entire "Beat the GrizzDog" challenge without awkward delays or errors.
Authentic Secret Exfiltration: The simulator plants the real lab secrets (GRIZZDOG-ROOT-KEY-9941, etc.) and models the vulnerability profile of each tier (Vulnerable yields to simple authority; Basic falls for fiction; Hardened requires character-by-character evasion; Paranoid refuses all probes).
Full Defense Pipeline Fidelity: Even in simulated mode, Phase 2 keyword firewall rules, Phase 3 OPA policy checks, and Phase 2/3 egress DLP scanners execute 100% live.

Classroom Studio Features & Canvas LMS Integration

For semester courses, cyber team practices, and CAE-CD hands-on labs, GrizzDog-AI includes turnkey workflows for student pairing and automated grading:

1. 📋 Official Canvas LMS Lab Report Exporter (1-Click)

Students export a submission ready to upload to Butler's Canvas LMS or turn in to instructors:

Partial Auto-Scoring (55 of 100 pts): The benchmark scores rubric Parts 2 (Gateway Rules, 35 pts: half visible attack catch rate, half held-out) and 3 (Usability, 20 pts: harmless tests from both suites). Parts 1 (Red Team Documentation) and 4 (Reflection) are marked Instructor-graded; no overall letter grade is shown.
Rule Provenance Check: The report includes a fingerprint of the student's filter_rules.py and how it differs from the calibrated preset. Rules identical to a shipped preset (blank, scaffolded, calibrated) get 0 auto-points, and rules that block nothing get no usability credit.
HMAC Signature (instructor-hosted servers): If the gateway is started with a REPORT_SECRET environment variable, each report ends with an HMAC-SHA256 signature over the whole report. Instructors check submissions with python lab/scripts/verify_report.py report.md (same secret), which detects any edit after export. Without REPORT_SECRET (e.g. a student's own laptop) the report is clearly marked UNSIGNED - practice copy. The signature only means something if students never see the secret.
Defense Brief Sentence Starters: The 5 reflection boxes start empty, with sentence starters shown as placeholder hints; unanswered questions appear as "(no response)".
Export Formats:
- 💾 Download .MD File: Clean Markdown document formatted for Canvas attachments.
- 🖨️ Print / Save as PDF: Styled with official Butler Community College CAE-CD letterhead and student honor pledge signature line.
- 📋 Copy Markdown: Instant clipboard copy for Canvas text-entry boxes.

2. 🥊 Red Team vs. Blue Team Head-to-Head Arena

Pair students for competitive adversarial defense drills:

Red Team (Attacker): Selects or crafts adversarial payloads against the sentry personas to bypass filters, leak exam keys, extract root keys, or exfiltrate FERPA records (+10 points per successful exploit).
Blue Team (Defender): Hardens filter_rules.py, rules.json, or system prompts in the Defense Studio to intercept attacks before they breach the model (+10 points per intercepted payload).
Live Scoreboard & Match Ledger: Real-time point tracking, leader banners, and round history that can be transferred directly into the Canvas LMS lab submission report with one click.

3. 📊 Turnkey Canvas LMS Batch Grader & Integrity Verifier (`batch_grade.py`)

Instructors can batch-evaluate student submissions downloaded directly from Canvas:

python lab/scripts/batch_grade.py submissions/ --secret "YOUR_INSTRUCTOR_SECRET" --csv canvas_grades.csv

Cryptographic HMAC Signature Verification: Confirms report integrity and catches tampering or forged auto-scores.
Rule Provenance Auditing: Verifies students wrote original defense rules rather than turning in unedited starter presets.
Direct Gradebook Export: Generates an import-ready canvas_grades.csv matching Canvas SIS headers (Student, SIS Login ID, GrizzDog Lab Auto Score (55 pts), Reflection Count (5)).

4. 🏷️ Threat Taxonomy: MITRE ATLAS & OWASP Top 10 for LLM Mapping

Every attack mission, benchmark test, and report item is tagged with formal industry classifications:

OWASP Top 10 for LLM: LLM01 (Prompt Injection), LLM02 (Sensitive Information Disclosure), LLM06 (Excessive Agency / Privilege Escalation), LLM07 (System Prompt Leakage).
MITRE ATLAS Matrix: AML.T0051.000 (Direct Prompt Injection), AML.T0051.001 (Indirect Prompt Injection), AML.T0054 (LLM Jailbreak), AML.T0057 (LLM Data Extraction).
Directly aligns with NSA/DHS CAE-CD Knowledge Units for academic accreditation.

Standalone Benchmark Evaluator (No Docker Needed)

Students and instructors can evaluate defense efficacy at any time:

python lab/scripts/evaluate_rules.py --verbose

Output with the shipped calibrated preset. It aces the visible tests but catches none of the held-out rewordings, which is the lesson: memorizing phrases is not a defense.

======================================================================

Held-out generalization suite. lab/benchmark/heldout_tests.json holds reworded, leetspeak, base64, translated, roleplay and spacing-trick versions of the attacks, obfuscated egress leaks, and harmless "over-blocking" questions. The UI, CLI and Canvas report show only the technique and pass count, never the test text. The shipped file is a public sample; for graded work, instructors should keep a private copy outside the repo and start the gateway with HELDOUT_TESTS_PATH=/path/to/private.json.

Live Demo Tier Switching

Switch between difficulty tiers during lecture:

python lab/scripts/set_tier.py blank        # Unprotected starting point
python lab/scripts/set_tier.py scaffolded   # Scaffolded student starting point
python lab/scripts/set_tier.py calibrated   # Full reference defense benchmark

Automatic Updates & Releases

start.bat / start.sh (or python start.py) run lab/scripts/update.py before the app starts:

Release channel (default): follows the newest tag named vMAJOR.MINOR.PATCH (e.g. v1.2.0) that is on main. Unfinished commits on main are never picked up, so booth laptops only run versions you've decided are ready. Until the first tag exists, nothing is updated.
Safe by design: fast-forward only, so it never overwrites or discards work. A copy with its own unpublished commits is left alone.
Student work is kept. Edits to filter_rules.py, policies/rules.json and lab/modelfiles/* are backed up (.grizzdog/backups/), the update is applied, and the edits are restored. If the new release also changed one of those files you're told, and your copy wins. Any other uncommitted change to a tracked file skips the update.
Self-check and rollback: the new code is compile-checked and the app is start-up tested on the unedited files. If that fails the update is undone and that release isn't retried until a newer one appears.
Offline-safe: no network, no git, or a ZIP download → it says so and starts the current version.
Model files changed? The lab models are rebuilt automatically (never downloading the base model).
See what's running: the version appears in the page header and the console, and in .grizzdog/version.json.

Check without changing anything: .\start.bat --check. Other channels: --channel main (latest commit; for developers) or --channel off.

Publishing a release (instructors): when main is ready for students or a booth:

git tag -a v1.1.0 -m "Booth fixes, new held-out tests"
git push origin v1.1.0

Every launcher on its release channel picks it up at its next start. To hold laptops at the current version (e.g. the night before an event), set GRIZZDOG_NO_UPDATE=1. Test the exact version you'll show first. For extra protection, sign tags (git tag -s) and set GRIZZDOG_REQUIRE_SIGNED_TAGS=1 on the laptops.

Updating to the Latest Lab Version

The launcher above does this for you. To update by hand instead:

If you already cloned the repository or need to pull the latest updates (new GrizzDog hardening tiers, in-browser 3-phase defense studio, Butler CC theming):

# 1. Pull the newest code from GitHub:
git pull origin main

# If you have local edits you want to overwrite:
# git fetch origin && git reset --hard origin/main

# 2. Restart or rebuild the web gateway container:
docker compose restart web
# Or for a full clean recreate: docker compose down && docker compose up -d --build

# 3. Rebuild all lab models in Ollama (picks up Modelfile changes):
python lab/scripts/build_models.py --docker

# 4. Open or refresh your browser:
# http://localhost:5000

Updating Docker to the Latest Version

If your Docker Desktop is outdated:

Docker Desktop (Mac & Windows): Open Docker Desktop > Click ⚙️ (Settings) > Software Updates > Check for updates > Download and install.
Windows (PowerShell): winget upgrade Docker.DockerDesktop
macOS (Terminal / Homebrew): brew upgrade --cask docker
Linux (Ubuntu/Debian): sudo apt-get update && sudo apt-get --only-upgrade install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin

`lab/scripts/secure_gateway.py`	The web gateway, Defense Studio, booth kiosk and arena (`http://localhost:5000`)
`lab/scripts/build_models.py`	Builds all 18 Ollama lab models (`--docker`, `--check`, `--only ta grader`)
`lab/scripts/evaluate_rules.py`	Scores `filter_rules.py` on the visible and held-out benchmark (`--verbose`)
`lab/scripts/batch_grade.py`	Turnkey Canvas LMS batch grading and HMAC verification for student report folders; outputs Canvas CSV
`lab/scripts/set_tier.py`	Swaps `filter_rules.py` to the `blank`, `scaffolded` or `calibrated` preset
`lab/scripts/verify_report.py`	Instructor check of signed Canvas reports (needs the same `REPORT_SECRET`)
`lab/scripts/make_qr.py`	Regenerates the booth QR code SVG (needs `pip install qrcode`)
`lab/scripts/benchmark.py` / `policy_eval.py` / `report_signing.py`	Shared modules (benchmark suites, Phase 3 local evaluator, report signing); not run directly

Acknowledgments & Upstream Lineage

GrizzDog-AI was built upon and adapted from the foundational cybersecurity architecture created by SixFiveMil in the open-source project Securing-AI.

We extend sincere gratitude and full credit to SixFiveMil for the pioneering concepts in multi-phase LLM security sandboxing, policy integration, and defensive benchmark design that formed the basis for this Butler Community College CAE-CD educational curriculum and quadruped robotics sentry expansion.
