Core Concepts and Skills You'll Need to Master
Alright, let's get down to the nitty-gritty. To succeed in the OSCP, you'll need to have a solid understanding of several core concepts and skills. This isn't an exhaustive list, but it covers the essentials. First and foremost, you'll need a good grasp of networking fundamentals. This includes understanding IP addressing, subnetting, TCP/IP protocols, and network architecture. You'll be spending a lot of time scanning networks, identifying hosts, and mapping out the attack surface, so a solid understanding of networking is crucial. Next, you need a firm handle on Linux. The OSCP lab environment is primarily Linux-based, and you'll be using the command line extensively. Get comfortable with navigating the file system, using command-line tools, and understanding Linux system administration concepts.
Another crucial area is web application security. You'll need to be familiar with common web vulnerabilities such as SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF). Knowing how to identify and exploit these vulnerabilities will be key to gaining access to target systems. Buffer overflows are another important topic. While not as prevalent as they once were, buffer overflows can still be a viable attack vector, and the OSCP exam often includes at least one buffer overflow challenge. Make sure you understand how they work, how to identify vulnerable applications, and how to write exploit code. Privilege escalation is also a critical skill. Once you've gained initial access to a system, you'll need to escalate your privileges to gain full control. This involves identifying and exploiting vulnerabilities that allow you to move from a low-privilege user to a root or administrator account. In addition, you must have experience with Active Directory. You'll likely encounter Active Directory environments in the lab, so you'll need to know how to enumerate users, groups, and trusts, and how to exploit common Active Directory vulnerabilities.
Finally, you'll need to be proficient with a variety of penetration testing tools. This includes tools for network scanning (like Nmap), vulnerability scanning (like OpenVAS), web application testing (like Burp Suite), and exploitation (like Metasploit). Familiarize yourself with these tools and understand how to use them effectively.
