Prerequisites: What You Need to Know Before Starting

Before you jump into OSCP preparation, it's essential to have a solid foundation in certain areas. This isn't a certification you can just breeze through – you need to put in the work! First, a basic understanding of networking is crucial. You should be familiar with networking concepts like IP addressing, subnetting, TCP/IP, and common network protocols (HTTP, DNS, etc.). If these terms sound like gibberish, don't worry! There are tons of free resources available to get you up to speed. Next up, you'll need to be comfortable with the Linux command line. The OSCP lab environment is heavily based on Linux, so you'll spend most of your time interacting with the operating system through the terminal. Get familiar with commands like ls, cd, grep, find, ifconfig, and netstat. You can practice these commands in a virtual machine or a Linux distribution. It's also super important to have a basic understanding of scripting. While you don't need to be a coding wizard, you should be able to read and understand simple scripts (e.g., Bash, Python) and be able to modify them to suit your needs. Scripting is essential for automating tasks and exploiting vulnerabilities. If you're new to scripting, check out online tutorials or courses. You should also get familiar with some programming languages that are commonly used in security, like Python and Bash. If you want to take your penetration testing skills to the next level, I suggest you study the basics of each one. Finally, a basic knowledge of Windows administration is useful, as you'll be working with Windows systems during the lab and exam. The OSCP is designed to be a challenging certification, so make sure you build a strong foundation before you start. This includes getting familiar with different operating systems and also knowing the basics of how the internet works. Taking the time to build a strong foundation in these areas will make your OSCP journey much smoother and more enjoyable.

Next, we have vulnerability scanning. This is where you use tools like OpenVAS or Nessus to scan the target for known vulnerabilities. Understanding how to interpret scan results and prioritize vulnerabilities is key. After you identify the vulnerabilities, you'll need to move on to exploitation. This involves using various techniques and tools to exploit the vulnerabilities you've found. This is the heart of the OSCP exam. You'll need to be proficient in exploiting various types of vulnerabilities, such as buffer overflows, web application vulnerabilities, and misconfigurations. You'll need to learn about different types of exploits and how to use them effectively. The main tools you'll need for this are Metasploit and various manual exploitation techniques. Then, you will need to learn the basics of Privilege Escalation, which consists of gaining access to higher-level privileges on a system. This involves identifying and exploiting vulnerabilities that allow you to escalate your privileges, such as misconfigured services or weak passwords. Web application security is another important topic. You'll need to understand common web application vulnerabilities, such as SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF). You'll also learn how to exploit these vulnerabilities. Finally, you will need to learn about Active Directory exploitation, which involves exploiting vulnerabilities in Active Directory environments. This includes understanding the structure of Active Directory, and how to exploit common misconfigurations. Don't worry, we'll dive deeper into all these topics later on in the article.
