Introduction
The demand for cybersecurity experts in the U.S. is soaring. Cybersecurity Ventures states that there will be 3.5 million vacant cybersecurity positions worldwide through 2025. Certifications such as the Offensive Security Certified Professional (OSCP) certificate highlight proficient individuals in this booming industry.
The OSCP certification is esteemed in the world of cybersecurity. This guide will lay out a detailed plan for budding security specialists, shedding light on the OSCP certification exam, how to gear up for it and the advantages it offers for your professional journey.
Understanding the OSCP Certification
The OSCP, provided by Offensive Security (OffSec), is a credential that affirms your expertise and knowledge in ethical hacking, particularly in penetration testing with Kali Linux tools. Ethical hacking, or penetration testing, entails simulating cyberattacks on systems, networks or web applications to uncover and resolve security weaknesses before malicious actors can exploit them.
The OSCP certification stands out from other certifications due to its rigorous and practical approach. Unlike certifications such as Certified Ethical Hacker (CEH), which emphasizes theoretical understanding, the OSCP requires significant hands-on skills and in-depth security comprehension.
This makes the OSCP certification ideal for those eager to demonstrate their practical penetration testing abilities.
The OSCP Certification Exam Format and Requirements
Exam Layout and Duration
The OSCP exam is a 24-hour hands-on test that mirrors a real-life network within a VPN. This network includes many machines with security weaknesses, and your task is to exploit these weaknesses to obtain root or administrative access.
Every machine is worth a set number of points based on its complexity, and you will need 70 points at least to pass successfully:
Three Independent Targets (60 points):
- 2-step targets with low and high privileges
- 20 points per machine
- 10 points for low-privilege
- 10 points for privilege escalation
Two Clients and One Domain Controller (40 points):
- Active Directory set
- Points are awarded only for the complete exploit chain
- No partial points are given
Once completing the exam, you will have an additional 24 hours to submit your documentation.
Technical Skills and Knowledge Needed
To ace the OSCP certification exam, you’ll need a solid understanding of several technical areas:
- Linux Administration: Comfort in using and navigating Linux systems.

Eligibility Requirements
Although there are no strict prerequisites, it’s best to have existing knowledge of Linux administration, networking and basic scripting. Preparatory courses such as Penetration Testing with Kali Linux (PWK) can be extremely helpful.
Personalized Study Plan
Crafting a tailored study plan is essential for OSCP certification exam success. Begin by evaluating your proficiency in Linux, networking, and scripting to pinpoint your strengths and areas for improvement. Use this evaluation to create a customized plan emphasizing weaker areas while bolstering your strengths.
Set dedicated times for studying, practicing in hands-on labs, and taking breaks to prevent burnout. Divide your plan into manageable segments with set deadlines for each target.
OSCP Certification Exam Tools and Techniques
Essential Tools
Throughout the OSCP exam, you’ll use several tools to accomplish your tasks:
- Kali Linux: A specialized penetration testing and security auditing system, preloaded with essential ethical hacking tools.
- Metasploit Framework: A robust tool for creating and running exploit code on target machines.
- Burp Suite: A web vulnerability scanner and testing tool designed to find and exploit weaknesses in web applications.
Common Methodologies
Penetration testing methodologies offer a structured way to perform security assessments. Two widely used approaches are:
- OSSTMM (Open Source Security Testing Methodology Manual): This manual provides a detailed guide for security testing, offering best practices and guidelines for comprehensive assessments. It includes various security aspects like network, physical and social engineering security.
- MITRE ATT&CK: This knowledge base details adversarial tactics and techniques from real-world incidents. It serves as a framework for analyzing attacker behavior. Penetration testers use MITRE ATT&CK to emulate advanced persistent threats (APTs) and assess the robustness of security measures.
Understanding Exploitation and Vulnerabilities Techniques
A thorough understanding of common vulnerabilities and exploitation methods is essential for the OSCP certification exam:
Common Vulnerabilities:
- SQL Injection: This occurs when attackers can run unauthorized SQL commands on a database by manipulating user input, potentially leading to data breaches, unauthorized data changes or full system compromise.
- Cross-Site Scripting (XSS): XSS happens when attackers inject malicious scripts into web pages that are viewed by other users. This can result in the theft of cookies, session tokens or other sensitive data.
Exploitation Techniques:
- Buffer Overflow: This technique involves sending excessive data to a buffer, causing it to overflow and overwrite adjacent memory, which can lead to arbitrary code execution.
- Privilege Escalation: This involves exploiting vulnerabilities to gain higher access rights, such as moving from a standard user to an administrator account.
