The more you practice, the better you'll become.

Preparing for the OSCP Exam: A Step-by-Step Guide

Okay, so you've got the concepts down, now what? Here's how to get ready for the OSCP exam:

1. The PWK Course and Lab Time

First things first, you'll need to purchase the PWK course. This gives you access to the course material, videos, and a lab environment. The labs are where you'll spend most of your time, practicing the skills you learn in the course. The more time you spend in the lab, the better prepared you will be for the exam. Seriously, don't skimp on the lab time. Try to complete as many lab exercises as possible, and work through the lab machines systematically. Aim to understand the methodology and how to approach each machine. Write up detailed notes on what you did, what worked, and what didn't. This will be invaluable when you are preparing your exam report.

2. Learn to Document Everything

This is a crucial point that many people overlook. In the OSCP exam, you are graded on your report, which must include detailed notes, screenshots, and explanations of your exploitation process. You will be required to write a detailed report documenting every step of your process. Take good notes as you work through the course and the labs. Use tools like CherryTree, OneNote, or Notion to organize your notes, and include screenshots of every step. Your report is worth a significant portion of your final score. If you don't document your work properly, you won't pass. The report should include detailed information on the vulnerabilities you identified, the exploitation techniques you used, and the steps you took to gain access to the target systems. Take screenshots throughout the process and include them in your report.

3. Build a Solid Foundation: Practice, Practice, Practice!

Practice makes perfect, right? Practice is key. The OSCP is a practical exam, so the more you practice, the better prepared you'll be. Beyond the PWK labs, there are other resources that offer great practice. Websites like Hack The Box (HTB) and TryHackMe (THM) have many machines with different levels of difficulty. This is a great way to apply the skills you've learned and build confidence. You can also look for Capture The Flag (CTF) competitions, which are a fun and challenging way to hone your skills and learn new techniques. Remember to approach each practice machine systematically. Start with information gathering and enumeration, then look for vulnerabilities. Document everything and be patient; you will learn something new every time. Doing the labs will allow you to build experience and become comfortable with the tools and techniques.

4. Understand the Exam Format

The OSCP exam is a 24-hour hands-on exam where you will be given access to a private network and asked to compromise several machines. You will also have 24 hours to write a detailed report documenting your work. The exam will challenge your ability to think critically, troubleshoot problems, and apply your knowledge under pressure. The exam is divided into several machines of varying difficulty. The goal is to obtain root or administrator access to these machines. You will be awarded points based on the number of machines you compromise and the level of access you obtain. Don't waste time on a single machine if you are not making progress. If you are stuck on a machine, move on to another one and come back to it later.
