You can continue to add to it, refine it, and use it as a reference for real-world pentesting engagements. Consider it your ongoing investment in your cybersecurity skills.

What to Include in Your OSCP/OSCE/OSEP Document Library

Okay, so you're sold on the idea of a document library. But what exactly should you include? Here's a breakdown of the essential categories and resources to consider:

1. Fundamental Concepts

Before diving into the nitty-gritty tools and techniques, make sure you have a solid grasp of the fundamentals. This includes:

• Networking: Understanding TCP/IP, subnetting, routing, and common network protocols is crucial. Include resources that explain these concepts clearly and concisely. Don't underestimate the importance of networking fundamentals. It's the bedrock of everything else we do in cybersecurity.
• Operating Systems: You'll be working primarily with Linux and Windows, so make sure you have resources covering their architecture, command-line interfaces, and security mechanisms. Mastering the command line is a non-negotiable skill for any aspiring pentester.
• Web Application Security: Web apps are a common target for attackers, so you need to understand vulnerabilities like SQL injection, XSS, and CSRF. Include resources like the OWASP Top Ten to stay up-to-date on the latest threats. Web application security is a huge area, so dedicate ample time to learning it.

2. Tools of the Trade

Pentesting involves using a variety of tools to scan, exploit, and maintain access to systems. Here are some key tools to include in your library:

• Nmap: The go-to tool for network scanning and reconnaissance. Document common Nmap commands, scripts, and techniques. Nmap is your reconnaissance Swiss Army knife. Learn it inside and out.
• Metasploit: A powerful framework for developing and executing exploits. Include modules, payloads, and techniques for using Metasploit effectively. Metasploit can seem intimidating at first, but mastering Metasploit is a game-changer.
• Burp Suite: An essential tool for web application penetration testing. Document how to use Burp Suite to intercept, analyze, and modify web traffic. Burp Suite is your web app testing companion. Get comfortable with its various features.
• SQLmap: An automated SQL injection tool. Document how to use SQLmap to identify and exploit SQL injection vulnerabilities. SQL injection is a classic vulnerability, and SQLmap is your weapon of choice.
• Hydra: A password-cracking tool. Document how to use Hydra to brute-force passwords for various services. Password cracking is a necessary skill, and Hydra is a powerful tool for the job.

3. Exploitation Techniques

Exploitation is the heart of pentesting. You need to understand how vulnerabilities work and how to exploit them. Include resources on:

• Buffer Overflows: A classic vulnerability that can lead to code execution. Document how buffer overflows work and how to exploit them. Buffer overflows are complex but rewarding to learn. They give you a deep understanding of how software works.
• Web Application Exploits: Techniques for exploiting vulnerabilities like SQL injection, XSS, and CSRF. Include real-world examples and case studies. Web app exploits are constantly evolving, so stay updated on the latest trends.
• Privilege Escalation: Techniques for gaining higher-level access on a system. Document common privilege escalation methods for both Linux and Windows. Privilege escalation is often the final step in a successful pentest.

4. Cheat Sheets and Quick References

Cheat sheets are your best friends during exams and real-world engagements. Create or collect cheat sheets for:

• Common Linux Commands: Essential commands for navigating the file system, managing processes, and configuring the system. Linux is the pentester's operating system of choice, so get comfortable with the command line.
• Nmap Syntax: Quickly recall common Nmap options and scripts. Nmap has a ton of options, so a cheat sheet can be a lifesaver.
• Metasploit Commands: Essential commands for using Metasploit modules and payloads. Metasploit has its own command structure, so a cheat sheet is helpful.
• Web Application Vulnerabilities: A quick reference for common web app vulnerabilities and how to identify them. Web app vulnerabilities can be subtle, so a cheat sheet can help you spot them.

5. Personal Notes and Writeups

Don't just collect information – process it. Add your own notes, summaries, and writeups to your document library. This will help you solidify your understanding and make the information more memorable.

• Lab Writeups: Document your experiences in practice labs. Explain the steps you took, the vulnerabilities you found, and how you exploited them. Lab writeups are invaluable for learning. They force you to think critically about what you've done.
• Vulnerability Summaries: Summarize the key aspects of different vulnerabilities. Explain how they work, how to identify them, and how to exploit them. Summarizing information is a great way to learn.
• Tool Usage Guides: Create your own guides for using specific tools. Explain the options, techniques, and best practices for each tool. Teaching others is a great way to learn.

How to Organize Your Document Library

Now that you know what to include, let's talk about organization. A disorganized library is as good as no library at all. Here are some tips for keeping your resources organized:

• Use a Consistent File Structure: Create a clear and logical file structure. For example, you might have top-level folders for "Fundamentals", "Tools", "Exploitation", and "Cheat Sheets". Within each folder, create subfolders for specific topics or tools. A well-defined file structure is essential for easy navigation.
• Naming Conventions: Use consistent naming conventions for your files and folders. This will make it easier to find what you're looking for. For example, you might name files using the format "[Topic] - [Tool] - [Description].pdf". Consistent naming makes searching a breeze.
• Indexing and Search: Consider using a tool that allows you to index and search your document library. This will make it much faster to find specific information. There are several good options available, such as local search tools or even cloud-based note-taking apps.
• Version Control: If you're working on a large document library, consider using a version control system like Git. This will allow you to track changes, revert to previous versions, and collaborate with others. Version control is a lifesaver when you're making lots of changes.

Tools for Building Your Document Library

You have several options when it comes to tools for building your document library. Here are a few popular choices:

• Notion: A versatile note-taking and organization tool that's perfect for building a document library. Notion allows you to create databases, wikis, and other types of content. Notion is a great all-in-one solution for many people.
