A-Team Security — Infrastructure & Security Agent Engineer
Oracle Cloud Infrastructure — CIS Foundations Benchmark 3.0 — AI-Powered Compliance Platform
---
## Overview
A-Team Security Agent is a self-hosted web application that automates **CIS Oracle Cloud Infrastructure Foundations Benchmark 3.0** compliance checks, powered by **OCI Generative AI** for intelligent analysis and an **MCP (Model Context Protocol)** server architecture for extensible task execution.
The platform combines security compliance scanning, AI-powered chat with **RAG (Retrieval-Augmented Generation)**, infrastructure exploration, and vector-based knowledge storage into a single, containerized solution with a **React 19 SPA** (TypeScript, Vite), **Oracle Dark Premium** theme (light/dark modes), **KPI dashboard** with compliance gauge, **i18n** (pt/en/es), and **Recharts** visualizations.
Distributed as pre-built Docker containers via **Oracle Container Registry (OCIR)** — no source code required.

## Quick Start
### Prerequisites
- Docker and Docker Compose v2
- Access to the OCI Container Registry (OCIR)
### 1. Configure
```bash
cp .env.example .env
```
Edit `.env`:
```env
OCIR_REGION=us-ashburn-1
OCIR_NAMESPACE=your_namespace
APP_SECRET=
```
### 2. Login to OCIR
```bash
docker login ${OCIR_REGION}.ocir.io
```
- **Username:** `/` or `/oracleidentitycloudservice/`
- **Password:** Auth Token (generate in OCI Console > Profile > Auth Tokens)
### 3. Run
```bash
docker compose up -d
```
### 4. Access
Open `http://localhost:8080`
The initial admin password is generated automatically and displayed in the backend logs:
```bash
docker compose logs backend | grep "password"
```
> You will be prompted to change the password on first login.

## Deploy on OCI (Terraform)
For production deployment on Oracle Cloud Infrastructure with Load Balancer, WAF, and SSL.
### Architecture
```
+--------------------------------------------------------------+
| Oracle Cloud |
| |
| +-----------------+ +--------------------------------+ |
| | | | | |
| | WAF Policy | | Private Subnet | |

## Configuration Guide
### Step 1 — OCI Credentials
Navigate to **OCI Credentials** tab and add:
| Field | Description |
|-------|-------------|
| Tenancy Name | Friendly name (e.g., `my-company`) |
| OCID Tenancy | `ocid1.tenancy.oc1..xxxxx` |
| OCID User | `ocid1.user.oc1..xxxxx` |
| Fingerprint | `aa:bb:cc:dd:ee:ff:...` |
| Region | `sa-saopaulo-1`, `us-ashburn-1`, etc. |
| Compartment OCID | `ocid1.compartment.oc1..xxxxx` |
| Private Key | `.pem` file |
Click **Test** to validate the connection.
### Step 2 — GenAI Model
1. Select the **OCI Credential** created in Step 1
2. Choose a **model** from the catalog (16 models across 5 providers)
3. Adjust parameters (temperature, max_tokens, etc.)
### Step 3 — ADB Vector + RAG (Optional)
For persistent vector storage and RAG-powered chat:
1. Add DSN (from tnsnames.ora)
2. Set credentials and upload Wallet ZIP
3. Select an **Embedding Model**
4. Register vector tables
### Step 4 — MCP Servers (Optional)
Register MCP servers for extended AI task execution:
| Type | Use Case |
|------|----------|
| `stdio` | Local Python scripts |
| `SSE` | Remote HTTP servers |
| `module` | Upload `.py` files directly |

## Environment Variables
| Variable | Required | Default | Description |
|----------|----------|---------|-------------|
| `OCIR_REGION` | Yes | — | OCI region for container registry |
| `OCIR_NAMESPACE` | Yes | — | OCIR tenancy namespace |
| `APP_SECRET` | Yes | — | 64-byte hex key for JWT/encryption (`openssl rand -hex 64`) |
| `JWT_EXPIRY_HOURS` | No | `12` | Token expiry in hours |
| `PORT` | No | `8080` | Frontend port |
| `CORS_ORIGINS` | No | — | Allowed origins (comma-separated) |
| `TZ` | No | `America/Sao_Paulo` | Timezone |
---
## Troubleshooting
**Cannot pull images from OCIR:**
Verify your `docker login` credentials and that the OCIR repositories exist in your namespace.
**Backend health check fails:**
Check logs: `docker compose logs backend`. Ensure `APP_SECRET` is set in `.env`.
**ADB connection fails (`DPY-6005`):**
Ensure the wallet ZIP contains `tnsnames.ora` and `ewallet.pem`. The DSN must match a service name in `tnsnames.ora`.
**GenAI returns 401/403:**
Verify the IAM policy `Allow group ... to use generative-ai-family in compartment ...` exists.
