At a Glance

Text-only GGUF Q4_K_M release; confirmed working with Ollama, llama.cpp, LM Studio, and Jan
1,000 curated training samples focused on sovereign AI red/blue-team security
CSS improvement over Gemma 4 E2B base: 4.21 → 6.18 (+1.97, +46.7% relative)
Sovereignty Premium of 61.8% vs Qwen3.6-35B-A3B full 7-area frontier reference (10.00)
Visible chain-of-thought leakage: 0% on the eval set
Garbled output rate: 0% on the eval set
Largest gains in A2 MCP Security (+2.71), A6 Sovereign SOC (+2.59), A7 Infrastructure (+2.53)

These results reflect the project-specific Security-SLM CSS benchmark and should not be read as a general claim against base Gemma 4 across all tasks.

Why This Model Exists

Security teams increasingly use AI agents to inspect alerts, query logs, review code, analyse cloud policy, and coordinate incident response. Hosted LLM APIs are hard to use in environments where prompts may contain incident logs, private hostnames, IAM policies, vulnerability details, internal source code, analyst notes, security-tool outputs, or accidental secrets.

This project explores a practical alternative: a small, locally deployable security model that runs inside private infrastructure and supports authorised red-team and blue-team work without anything leaving the perimeter.

What It Is Good At

Web and API penetration testing

OWASP Top 10 analysis: injection, XSS, CSRF, IDOR, broken access control, security misconfiguration
API attack patterns: BOLA/IDOR, broken object-property-level authorisation, mass assignment, JWT attacks, rate-limit bypass
Authentication and authorisation attack chains
Burp Suite response inspection and differential analysis workflows

AI and LLM security

Prompt injection (direct and indirect) and jailbreaking techniques and defences
Sensitive information disclosure and data exfiltration via RAG systems
RAG and vector DB attacks: document poisoning, retrieval manipulation, embedding inversion
MCP tool-description poisoning, malicious tool schemas, argument abuse
Narrative and social-engineering prompt injection
Multi-turn payload splitting and semantic drift detection
Agent memory poisoning and recursive tool-call resource exhaustion
Reconnaissance and model fingerprinting
Multi-agent delegation abuse and trust escalation

Cloud and infrastructure

Cloud SSRF, metadata service exploitation, IAM privilege escalation
URL-fetching agent SSRF and cloud metadata exposure
Injection attacks: SQL, NoSQL, command injection, LDAP, template injection

Tooling and automation

Automated security tooling workflows: nmap, nuclei, ffuf, sqlmap
Tool-call execution in JSON array format: [{"tool_name": "...", "parameters": {...}}]
Common vulnerability analysis and CVE triage
AI/LLM/API CVE triage for private inference gateways

Blue team and SOC

RBAC and object-level authorisation testing
SOC triage, audit logging, and alert runbooks
Detection logic, SIEM queries, and telemetry design
Human approval gates for high-risk tools
Sovereign deployment and compliance controls (5-domain: data residency, inference isolation, audit logging, break-glass access, SIEM integration)
MCP runtime argument validators and callback/webhook allowlist enforcement

Report writing

Pentest finding structure: description, reproduction steps, business impact, CVSS score, remediation
Executive summary and technical findings formatting

Example Prompts

Agentic security (structured analysis):

Design controls to prevent MCP tool-description poisoning in a private SOC environment.
Include manifest validation, logging signals, and runtime enforcement.

Expected style:

Reasoning Summary:
MCP tool descriptions are attacker-controlled text parsed by the agent runtime.
Poisoned descriptions can redirect tool selection, modify arguments, and exfiltrate context.

Threat Model:
An attacker publishes or modifies MCP tool metadata so an AI agent treats malicious
descriptions as trusted operational instructions.

Risk Level:
High — poisoned tool metadata can influence tool choice, arguments, and execution flow.

Controls:
- Require signed MCP manifests.
- Treat descriptions as untrusted data.
- Block secret requests, callback URLs, and policy override language.
- Enforce permissions outside natural-language descriptions.
- Log schema changes and failed validation decisions.

Sovereign Deployment Notes:
Run validation locally inside the SOC and keep manifest history in an internal audit store.

Tool-call (automated security workflow):

[Red Team] Run an authorised BOLA test against /api/v1/users/{id} in the lab environment.
Use a tool call.

Expected tool-call output:

[{"tool_name": "run_command", "parameters": {"command": "ffuf -u 'https://lab-target.internal/api/v1/users/FUZZ' -w numbers_1_200.txt -H 'Authorization: Bearer OWN_TOKEN' -mc 200 -o bola_results.json", "description": "Fuzz user ID to detect BOLA"}}]

Pentest report writing:

Write a structured pentest finding for a confirmed SQL injection on /login using the
username parameter. Include CVSS score and remediation.

Expected style:

Finding:
Authenticated SQL injection in the /login endpoint via the username parameter.

Reproduction Steps:
1. Submit a POST request to /login with username set to admin' OR '1'='1' --
2. Observe authenticated session returned without valid credentials.
3. Repeat with sqlmap to confirm the injection point and extract schema.

Business Impact:
Full authentication bypass and likely read access to the user table,
including credential material.

CVSS:
9.8 (Critical) — AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Remediation:
- Replace string concatenation with parameterised queries or a prepared-statement ORM call.
- Apply input validation on username length and character set at the application boundary.
- Add a WAF rule for SQL injection patterns as a defence-in-depth control.
- Rotate any credentials accessible from the affected database and review audit logs for
  prior exploitation.

Note: GPT-5.3-mini v2 scores reflect a condensed single-batch response (all 7 prompts in one request), yielding SC=1 on A1–A4 due to omitted code blocks. Individual focused prompts would likely yield higher scores.

Safety Posture

Security-SLM is intended for authorised defensive and lab-scoped security work.

Recommended deployment controls:

Keep inference inside approved infrastructure
Do not grant direct destructive tool access
Place a policy gateway before tool execution
Require human approval for high-impact actions
Enforce per-tool schemas and allowlists
Log prompts, outputs, tool calls, and policy decisions
Redact secrets before model context
Block SSRF paths for URL-fetching tools
Validate MCP manifests and schemas before registration
Monitor multi-turn semantic drift and memory poisoning

Not Intended For

Do not use this model for:

Unauthorised intrusion
Credential theft
Malware deployment
Destructive cloud operations
Evasion guidance for real-world abuse
Autonomous production changes without human approval
Replacing qualified security professionals

Known Limitations

The dataset is small by production standards (1,000 samples). A real SOC deployment would benefit from a larger, domain-specific corpus.
The automated CSS evaluation uses heuristic pattern matching, not a full LLM-as-judge pipeline. LLM-as-judge API evaluation is planned.
Tool-call training coverage is limited (~8 examples). Additional tool-call samples will improve accuracy and reduce free-text fallback.
The model does not embed tools in its weights. Tools must be supplied by an external agent runtime, MCP server, or application policy gateway.
Without a configured system prompt, the model can revert to the base Gemma identity. Load the provided Modelfile or set the system prompt manually.
Human review is required for all security-critical decisions.

Roadmap

Expand dataset from 1,000 to 1,000+ high-quality samples across all capability areas
Add LoRA rank 32 training run with explicit gradient clipping
Publish a 100+ prompt held-out benchmark with human expert scoring and Cohen's kappa
Add DPO or ORPO preference tuning on identity and tool-call responses
Run automated LLM-as-judge API evaluations to complement human-judged scores
Expand tool-call training coverage to 50+ examples
Re-evaluate GPT-5.3-mini with individual focused prompts for higher-fidelity comparison
Add multimodal (image/audio) security datasets in a separate future release

Related Releases

This model is the second release in an ongoing open-source research effort on sovereign AI security models. The earlier release, security-slm-unsloth-1.5b, is a 1.5B-parameter Unsloth-based model focused on prompt hijacking, agentic lateral movement, and MCP exploitation. The current Gemma 4 E2B release uses a stronger base model and broadens coverage to web and API pentesting, RAG and vector DB attacks, SOC triage, and sovereign deployment controls.
