OSCP Complete Guide 2026: Offensive Security Certified Professional
The gold standard for penetration testing professionals.
Table of Contents
What is OSCP?
The Offensive Security Certified Professional (OSCP) is the most respected hands-on penetration testing certification in the cybersecurity industry. Offered by Offensive Security (OffSec), it proves you can identify vulnerabilities, develop exploits, and successfully compromise systems in real-world scenarios.
Unlike multiple-choice certifications, OSCP requires a grueling 24-hour practical exam where you must hack into multiple machines and write a professional penetration test report. This "Try Harder" approach ensures certified professionals possess genuine skills, not just theoretical knowledge.
OSCP comes with the PEN-200 course (Penetration Testing with Kali Linux), providing structured learning materials and access to a lab environment with dozens of vulnerable machines to practice on. The certification is highly sought after by employers and often required for senior penetration testing positions.

PEN-200 Course Content
The PEN-200 course covers comprehensive penetration testing methodology:
Information Gathering
- Passive reconnaissance (OSINT)
- Active scanning and enumeration
- DNS, SMTP, SNMP enumeration
- Web application reconnaissance
Vulnerability Analysis
- Network vulnerability scanning
- Web application vulnerabilities (OWASP Top 10)
- Finding public exploits and CVEs
- Manual vulnerability verification
Exploitation
- Buffer overflow attacks (Windows, Linux)
- Web application exploitation
- Client-side attacks
- Locating and modifying public exploits
- Antivirus evasion fundamentals
Post-Exploitation
- Privilege escalation (Windows and Linux)
- Lateral movement techniques
- Password attacks and cracking
- Pivoting and tunneling
- Active Directory attacks
Penetration Testing Methodology
A structured approach is essential for exam success.
1. Enumeration (Most Important)
- Port scanning with Nmap
- Service version detection
- Directory/file brute forcing
- Script enumeration (NSE scripts)
- Rule: "Enumerate harder" - 80% of success is thorough enumeration
2. Initial Access
- Identify vulnerable services
- Search for public exploits (searchsploit, Google)
- Modify exploits as needed
- Gain initial shell access
3. Privilege Escalation
- Run enumeration scripts (linPEAS, winPEAS)
- Check for misconfigurations
- Find credential files
- Exploit kernel vulnerabilities (last resort)
- Escalate to root/SYSTEM
4. Documentation
- Screenshot everything
- Note all commands used
- Record proof.txt flags
- Document exploitation steps reproducibly
Essential Tools
Tools you must master for OSCP:
Enumeration
- Nmap: Port scanning and service detection
- Gobuster/Feroxbuster: Directory brute forcing
- enum4linux: SMB/NetBIOS enumeration
- Nikto: Web server vulnerability scanning
Exploitation
- Metasploit: Exploit framework (limited use on exam)
- Searchsploit: Local exploit database
- Burp Suite: Web application testing
- SQLMap: SQL injection (limited use)
Post-Exploitation
- linPEAS/winPEAS: Privilege escalation enumeration
- Chisel: Pivoting and tunneling
- Mimikatz: Windows credential extraction
- Impacket: Network protocol tools
Exam Strategy
Maximize your chances of passing the 24-hour exam:
Time Management
- Start with AD set (40 points) or easiest standalone
- Don't spend more than 2-3 hours on one machine
- Take breaks - fatigue leads to mistakes
- Leave 3-4 hours for report writing
Exam Tips
- Run full port scans immediately on all targets
- Enumerate thoroughly before attempting exploits
- Take detailed notes and screenshots as you go
- If stuck, move to another machine
- Have food and caffeine prepared
- Sleep before exam - fatigue kills performance
Report Requirements
- Professional executive summary
- Step-by-step reproduction instructions
- Screenshots of key steps and proof flags
- Remediation recommendations
- Submit within 24 hours of exam end
