# Building a Cybersecurity Lab with Docker and Active Directory Integration

## Introduction
This guide provides a comprehensive walkthrough for creating an advanced cybersecurity lab environment using Docker and Docker Compose, integrated with a `homelab.local` Active Directory domain. The lab is designed to offer a flexible, scalable, and easily manageable platform for cybersecurity professionals and enthusiasts to practice, experiment, and enhance their skills in various security domains.

## Lab Architecture
The lab architecture consists of the following key components:
1. **Learning Paths**: The lab is organized into distinct learning paths, each focusing on a specific cybersecurity domain, such as network security, web application security, incident response, and malware analysis. This structure enables targeted skill development and focused experimentation.

2. **Docker Containers**: Each learning path is implemented using Docker containers, providing isolated and reproducible environments for different security scenarios and tools. Containers ensure efficient resource utilization and ease of management.

3. **Docker Compose**: Docker Compose is employed for orchestrating and managing the containers within each learning path. It allows for defining and configuring multiple services, networks, and volumes, simplifying the deployment and management of complex security environments.

4. **Active Directory Integration**: The lab is integrated with a `homelab.local` Active Directory domain, enabling centralized user and resource management. This integration provides a realistic enterprise network simulation and allows for practicing security scenarios in a controlled Active Directory environment.

## Lab Setup
To set up the cybersecurity lab, follow these step-by-step instructions:

### Prerequisites
- A host machine or dedicated server with sufficient resources (CPU, RAM, storage) to run multiple Docker containers.
- Docker and Docker Compose installed on the host machine.
- Access to the `homelab.local` Active Directory domain and its resources.

### Step 1: Active Directory Integration
1. Ensure that the `homelab.local` Active Directory domain is properly set up and accessible from the host machine.
2. Create the necessary user accounts, security groups, and organizational units (OUs) within the Active Directory domain to mirror a realistic enterprise environment.

### Step 2: Docker and Docker Compose Setup
1. Install Docker and Docker Compose on the host machine following the official documentation for your operating system.
2. Verify the successful installation by running `docker --version` and `docker-compose --version` in the terminal.

### Step 3: Learning Paths Structure
1. Create a dedicated directory for each learning path on the host machine, such as `network-security`, `web-app-security`, `incident-response`, and `malware-analysis`.
2. Within each learning path directory, create a `Dockerfile` that defines the container environment, including the necessary tools, dependencies, and configurations specific to that learning path.
3. Create a `docker-compose.yml` file in each learning path directory to define the services, networks, and volumes required for that specific path.

### Step 4: Configuration and Deployment
1. Customize the `Dockerfile` for each learning path, specifying the base image, installing required packages, and configuring the environment variables and settings.
2. Modify the `docker-compose.yml` file for each learning path, defining the services, networks, and volumes necessary for the specific security scenario or tool.
3. Use Docker Compose to build and deploy the containers for each learning path by running `docker-compose up -d` in the respective directory.

### Step 5: Central Management
1. Create a central `docker-compose.yml` file at the root level of the lab directory to manage and orchestrate all the learning path containers collectively.
2. Consider using tools like Portainer or Rancher for a web-based GUI to manage and monitor the Docker containers, networks, and volumes across the entire lab.

## Cybersecurity Learning Paths
The lab provides the following learning paths to cover various aspects of cybersecurity:

### 1. Network Security
- **Packet Analysis**: Utilize tools like Wireshark and tcpdump to capture and analyze network traffic, identify anomalies, and detect potential security threats.
- **Firewall Configuration**: Configure and manage firewalls using tools like iptables and pfsense to control network traffic, implement access controls, and enforce security policies.
- **Intrusion Detection and Prevention**: Deploy and configure intrusion detection systems (IDS) and intrusion prevention systems (IPS) using tools like Snort and Suricata to monitor network traffic and detect and prevent malicious activities.
- **VPN and Secure Communication**: Set up and configure virtual private networks (VPNs) using OpenVPN or WireGuard to establish secure communication channels between different network segments and remote locations.

```

### 2. Web Application Security
- **Vulnerability Assessment**: Perform web application vulnerability scanning and assessment using tools like OWASP ZAP, Burp Suite, and Nikto to identify common web vulnerabilities such as SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF).
- **Penetration Testing**: Conduct in-depth penetration testing on web applications using tools and frameworks like Metasploit, sqlmap, and BeEF to identify and exploit vulnerabilities, and assess the application's resilience to attacks.
- **Web Application Firewall (WAF)**: Configure and deploy WAFs using tools like ModSecurity and NAXSI to protect web applications from common attacks, enforce security rules, and monitor web traffic for suspicious activities.
- **API Security**: Test and secure RESTful APIs using tools like Postman and Swagger to validate API functionality, authentication, authorization, and input validation.

### 3. Incident Response and Forensics
- **Incident Response Planning**: Develop and practice incident response procedures using the lab environment to simulate security incidents, test incident response plans, and improve incident handling capabilities.
- **Log Analysis**: Collect and analyze system and application logs using tools like ELK stack (Elasticsearch, Logstash, Kibana) and Splunk to identify security events, detect anomalies, and investigate incidents.
- **Memory Forensics**: Perform memory forensics on compromised systems using tools like Volatility and Rekall to analyze memory dumps, identify malicious processes, and extract valuable artifacts for incident investigation.
- **Network Forensics**: Conduct network forensics using tools like NetworkMiner and Xplico to analyze network traffic captures (PCAP files), reconstruct network events, and investigate network-based attacks.
