Setting Up Your Databricks Environment

Alright, let’s get our hands dirty and actually set up our environment. It's really pretty straightforward, and I'll walk you through the basic steps to set up your Databricks environment so you can get started with your OSCP prep. Remember, this is about maximizing your efforts, so make sure you follow each step.

1. Account Creation and Access

  • Go to the Databricks website and create a free account. Make sure to use a valid email address because you will need to verify your account. It's also important to pick a strong password; you will be dealing with sensitive information.
  • After the account is created, you'll receive a verification email. Click the link to verify your account and complete the initial setup process. This might involve setting up your workspace and region; choose the option that best suits your needs, considering the geographic location and any latency considerations.
  • Log in to your Databricks account and navigate to the workspace. This is the central location where you'll manage your clusters, notebooks, and other resources.

2. Launching a Cluster

  • Inside your Databricks workspace, you'll need to create a cluster. A cluster is a collection of computational resources (virtual machines) where you'll run your analysis and testing tasks. Click on the “Compute” tab in the left-hand navigation pane and then click “Create Compute”.
  • When creating the cluster, you'll be prompted to select the cluster configuration. For the free tier, there might be certain limitations on the cluster size and available resources. Choose the smallest size that will meet your needs. We are here to learn!
  • Configure the cluster settings based on your requirements. This includes specifying the cluster mode, the Databricks runtime version (choose a recent one), and auto-termination settings (to avoid unnecessary charges). If you don't use it, you will lose your resources!

3. Notebook Creation and Configuration

  • Create a notebook. Notebooks are the main interface where you will write and execute code, run commands, and document your findings. You can create a new notebook by clicking “Create” and selecting “Notebook.” Give it a descriptive name to reflect its purpose.
  • Choose the language for your notebook. You can use languages like Python or R. Python is the most used option for penetration testing and cybersecurity. Select the language you're most familiar with or the one that fits your testing needs. You can switch languages as necessary.
  • Connect your notebook to the cluster you created in the previous step. In the notebook interface, you should see a dropdown to select your cluster. Choose the cluster you created to execute code and run commands on the cluster's resources. Now you can run your commands, and that means you are ready to do whatever you need!

Essential Tools and Configurations for PSSI

With your Databricks environment set up, you can now start installing and configuring the tools you'll use to practice for the PSSI assessments. These tools will help you to get familiar with common penetration testing methodologies and improve your skills. Here’s how to set up some of the most essential ones:

1. Metasploit Setup and Usage

  • Installation: Metasploit is one of the most powerful penetration testing frameworks. It's not usually pre-installed on Databricks clusters, so you'll need to install it. You can do this by executing the appropriate installation commands in your notebook (e.g., using apt-get install metasploit-framework if you're using a Debian-based image). Just make sure you understand the basics of the commands and use them as your own.
  • Configuration: After installation, configure Metasploit by setting up a database (e.g., PostgreSQL) to store your data and results. You can configure the database connection settings within Metasploit. Check online documentation for the specific database setup to integrate the tools.
  • Usage: Launch Metasploit from your notebook and start exploring its modules. Practice using different exploits, payloads, and post-exploitation techniques. Start with basic network scanning and vulnerability assessments, then move on to more advanced exploits.

2. Network Scanning with Nmap

  • Installation: Nmap is another crucial tool for network discovery and security auditing. You can install it on your Databricks cluster using the package manager. Just like with Metasploit, use the command line to install Nmap (e.g., apt-get install nmap).
  • Configuration: Nmap typically doesn't require extensive configuration. However, you can configure the scan options, such as the scan type, port ranges, and output format, directly in your notebook. Adapt the configurations to practice the different types of scans.
  • Usage: Use Nmap to scan different networks and identify open ports, services, and potential vulnerabilities. Practice writing scripts to automate your scan tasks and analyze the results. Try different scanning techniques (TCP connect, SYN, UDP) and experiment with advanced features like version detection and OS fingerprinting.

3. Web Application Scanning

  • Installation: Install tools like OWASP ZAP or Burp Suite. You can install the ZAP from the terminal, just as you did with the other tools, or you can download the .jar file for Burp Suite. Make sure you have java installed to launch Burp Suite.
  • Configuration: For ZAP, configure the proxy settings to capture and analyze web traffic. In Burp Suite, configure the proxy settings and set up the scope of your target applications.
  • Usage: Use these tools to scan for web vulnerabilities, such as SQL injection, cross-site scripting (XSS), and other common security flaws. Practice intercepting and modifying web requests to understand and exploit vulnerabilities. Analyze the scan reports to find issues and learn how to remediate them.

4. Setting up a Vulnerable VM

  • Setup: Deploy a vulnerable VM. This could be a pre-built vulnerable VM image (like those available on VulnHub or Hack The Box) on your Databricks environment. You can create a VM with VirtualBox and upload it.
  • Configuration: Configure the network settings to ensure your vulnerable VM can communicate with your Databricks cluster. This usually involves creating a virtual network and assigning IP addresses.
  • Usage: Once the VM is set up, start practicing your penetration testing skills by scanning and exploiting vulnerabilities on the vulnerable VM. Use the tools you configured earlier to assess and exploit the machine. Try to get root!

Optimizing Your Databricks Lab

Okay, so you have your Databricks lab set up. Now, let’s make it even better! To get the most out of your Databricks environment for OSCP and PSSI preparation, you’ll need to optimize it. Here are some tips to help you:

1. Scripting and Automation

  • Automate repetitive tasks: Use scripts to automate common tasks like network scanning, vulnerability assessment, and exploit execution. This will improve your efficiency.
  • Use scripting languages: Practice using languages like Python and Bash to automate tasks. These languages are essential for any penetration tester.
  • Use the Databricks CLI: To automate the setup and teardown of clusters and configurations.

2. Version Control and Collaboration

  • Use version control: Use Git to track changes to your scripts and configurations. This allows you to revert to earlier versions if something goes wrong.
  • Share your work: Share your notebooks and configurations with other OSCP students to improve the collaborative environment.
  • Work together: Collaborate with your peers in the community to get new ideas and insights.

3. Monitoring and Logging

  • Enable logging: Configure logging in your scripts and applications to record all the actions and results.
  • Monitor your environment: Regularly monitor your Databricks environment for performance issues and errors.
  • Use logs to troubleshoot: Review the logs to understand and troubleshoot issues you face during your testing.
