## Overview
|
|
|
|
Beelzebub is an advanced honeypot framework designed to provide a highly secure environment for detecting and analyzing cyber attacks. It offers a low code approach for easy implementation and uses AI to mimic the behavior of a high-interaction honeypot.

|
|
|
## Key Features
|
|
|
|
Beelzebub offers a wide range of features to enhance your honeypot environment:
|
|
|
|
- Low-code configuration: YAML-based, modular service definition
|
|
- LLM integration: The LLM convincingly simulates a real system, creating high-interaction honeypot experiences, while actually maintaining low-interaction architecture for enhanced security and easy management.
|
|
- Multi-protocol support: SSH, HTTP, TCP, MCP(Detect prompt injection against LLM agents)
|
|
- Prometheus metrics & observability
|
|
- Docker & Kubernetes ready
|
|
- ELK stack ready, docs: [Official ELK integration](https://www.elastic.co/docs/reference/integrations/beelzebub)

|
## Code Quality
|
|
|
|
We are strongly committed to maintaining high code quality in the Beelzebub project. Our development workflow includes comprehensive testing, code reviews, static analysis, and continuous integration to ensure the reliability and maintainability of the codebase.
|
|
|
|
### What We Do
|
|
|
|
* **Automated Testing:**
|
|
Both unit and integration tests are run on every pull request to catch regressions and ensure stability.
|
|
|
|
* **Static Analysis:**
|
|
We use tools like Go Report Card and CodeQL to automatically check for code quality, style, and security issues.
|
|
|
|
* **Code Coverage:**
|
|
Our test coverage is monitored with [Codecov](https://codecov.io/gh/mariocandela/beelzebub), and we aim for extensive coverage of all core components.
|
|
|
|
* **Continuous Integration:**
|
|
Every commit triggers automated CI pipelines on GitHub Actions, which run all tests and quality checks.
|
|
|
|
* **Code Reviews:**
|
|
All new contributions undergo peer review to maintain consistency and high standards across the project.
|
|
|
|
## Quick Start
|
|
|
|
You can run Beelzebub via Docker, Go compiler(cross device), or Helm (Kubernetes).
|
|
|
|
### Using Docker Compose
|
|
|
|
1. Build the Docker images:
|
|
|
|
```bash
|
|
$ docker-compose build
|
|
```
|
|
|
|
2. Start Beelzebub in detached mode:
|
|
|
|
```bash
|
|
$ docker-compose up -d
|
|
```
|
|
|
|
|
|
### Using Go Compiler
|
|
|
|
1. Download the necessary Go modules:
|
|
|
|
```bash
|
|
$ go mod download
|
|
```
|
|
|
|
2. Build the Beelzebub executable:
|
|
|
|
```bash
|
|
$ go build
|
|
```
|
|
|
|
3. Run Beelzebub:
|
|
|
|
```bash
|
|
$ ./beelzebub
|
|
```
|
|
|
|
### Deploy on kubernetes cluster using helm
|
|
|
|
1. Install helm
|
|
|
|
2. Deploy beelzebub:
|
|
|
|
```bash
|
|
$ helm install beelzebub ./beelzebub-chart
|
|
```
|
|
|
|
3. Next release
|
|
|
|
```bash
|
|
$ helm upgrade beelzebub ./beelzebub-chart
|
|
```
|
|
|
|
## Example Configuration
|
|
|
|
Beelzebub allows easy configuration for different services and ports. Simply create a new file for each service/port within the `/configurations/services` directory.
|
|
|
|
To execute Beelzebub with your custom path, use the following command:
|
|
|
|
```bash
|
|
$ ./beelzebub --confCore ./configurations/beelzebub.yaml --confServices ./configurations/services/
|
|
```
|
|
|
|
Here are some example configurations for different honeypot scenarios:
|
|
|
|
### MCP Honeypot
|
|
|
|
#### Why choose an MCP Honeypot?
|
|
|
|
An MCP honeypot is a **decoy tool** that the agent should never invoke under normal circumstances. Integrating this strategy into your agent pipeline offers three key benefits:
|
|
|
|
* **Real-time detection of guardrail bypass attempts.**
|
|
|
|
Instantly identify when a prompt injection attack successfully convinces the agent to invoke a restricted tool.
|
|
* **Automatic collection of real attack prompts for guardrail fine-tuning.**
|
|
|
|
Every activation logs genuine malicious prompts, enabling continuous improvement of your filtering mechanisms.
|
|
* **Continuous monitoring of attack trends through key metrics (HAR, TPR, MTP).**
|
|
|
|
Track exploit frequency and system resilience using objective, actionable measurements.
