Modern enterprises must understand possible threat actors, the tools of their trade, and how they employ them in order to successfully defend their assets. This necessitates consciously thinking and behaving like them. This is when penetration testing (pen testing) comes into play.

Penetration testers uncover and assist in the resolution of security flaws in businesses' networks. Pen testing necessitates knowledgeable testers who frequently work for specialist penetration testing organizations since it is far more detailed than an automated vulnerability evaluation. Organizations are increasingly preferring to hire penetration testers that possess the Offensive Security Certified Professional (OSCP) certification.

What exactly is an Offensive Security Certified Professional (OSCP)?

Offensive Security, a business that specializes in penetration testing training and certifications, offers the OSCP, a well-respected ethical hacking certification. Offensive Security provides a number of certificates, the OSCP being one of the most well-known.

OSCP is a basic certification that teaches penetration testing methodology as well as how to use the tools that come with the Kali Linux distribution.

What is the OSCP certification training?

The Offensive Security Certified Professional (OSCP) certification program focuses on offensive information security abilities that may be applied in the field. It is divided into two parts: a nearly 24-hour pen testing exam and a documentation report that is due 24 hours following the exam. The OSCP exam is highly hands-on.

You must first complete the Penetration Testing with Kali (PWK) course before taking the OSCP test. You must complete the course in order to be eligible to take the OSCP. In addition to the knowledge gained through the course, it opens the door to a variety of professional options in information security. Those who pass, of course, have bragging rights.

The OSCP certification verifies a candidate's ability to carry out the following methods and attacks:

  • To gather and enumerate targets, use several operating systems and services.
  • Create simple scripts and tools to help in Pentesting.
  • Analyze, fix, change, cross-compile, and port exploit code
  • Carry out both remote and client-side assaults
  • Use XSS, SQL injection, and other online application flaws to your advantage.
  • Use tunneling techniques to get around firewalls.
  • Required exam:

To obtain the OSCP certification, you must pass one test – the 24-hour, proctored OSCP exam.

  • Prerequisite:

Offensive Security needs the Penetration Testing with Kali Linux (PwK) course, which is included in the OSCP course package, before trying this certification.

  • Recommended experience:

Before taking this test, Offensive Security suggests that you have acceptable Linux abilities, knowledge with Bash scripting, basic Perl or Python skills, and a strong grasp of TCP/IP and networking.


Tips for Exam

  • Have faith in yourself.
  • Maintain your cool and calm.
  • If you don't acquire access to one or two computers in a short period of time, as described in previous posts, don't bother.
  • Enumerate thoroughly.
  • Take frequent pauses. Take a short walk to obtain some fresh air.
  • Take screenshots and proofs of concept (POCs) promptly after each exploitation phase.
  • Once you've recovered the flags (local.txt and proof.txt), submit them to the test panel right away.

I've seen a lot of individuals fail exams because they lose their patience. So never become tense. Maintain a state of calm and relaxation at all times. Try HARDER!

How difficult is it to obtain the OSCP certification?

If you ask OSCP candidates about the test's difficulty level, you'll receive a variety of responses, but the majority say it's the most challenging exam they've ever taken. This is why it is vital to plan ahead of time.

The PWK course does not cover everything, but the contents are plenty to get you started. I cannot express enough how important it is to prepare ahead of time for the course. Here's a rundown of everything you'll need to know to prepare for the OSCP:

  1. Linux and Windows Environment- You must be comfortable with both the Linux and Windows environments. These will assist you in detecting signs of privilege escalation. I'm a Windows person who learnt Linux the hard way during the labs.
  2. Linux and Windows Commands - Understanding Linux and Windows commands is really beneficial. Refresh your memory!
  3. Basic Programming Knowledge - Expect to debug and rewrite vulnerabilities, thus be familiar with Bash Scripting. This will assist you in automating duplicate chores.
  4. Web application assaults (SQLi, XSS, Local File Inclusion, Remote File Inclusion, and Command Execution) - The labs will contain a significant amount of web application material. Additionally, practice evading site security filters for injection attacks.
  5. Metasploit Framework — Refresh your memory on how to create payloads in various formats, how to use multiple handlers, and how to differentiate between staged and non-staged payloads. Knowing these facts will allow you to save time during your test.
  6. Nmap - Various scanning techniques and Nmap NSE Scripts will be extremely useful throughout your lab or test.
  7. Netcat and Ncat- You'll be utilizing Netcat and Ncat a lot during the OSCP.
  8. Wireshark and tcpdump - These are crucial since you'll be debugging your exploit with Wireshark - or tcpdump if your system doesn't have a GUI.
  9. Windows and Linux Privilege Escalation - In addition to exploiting kernel vulnerabilities, familiarize yourself with misconfigurations such as weak service/file permissions and NFS/Shares.
  10. Escaping restricted shells and spawning shells- Escaping restricted shells and spawning shells are two things you'll come into a lot during your OSCP.
  11. File transfer - It is critical that you understand the various methods for transferring files to a destination system.




Frequently Asked Question (FAQ)


Q 1. How many times may I sit for the OSCP exam?

A 1. Not everyone succeeds on the first try. Subject to a cooling down period, you may retake the OSCP test as many times as you need. The price for retaking the OSCP is $150.

Q 2. Is OSCP suitable for beginners?

A 2. Although Offensive Security considers the OSCP to be a starter certification, several other certification providers consider it to be an intermediate/advanced test. They must also have a strong grasp of TCP/IP networking, as well as basic Bash and/or Python scripting and real-world penetration testing experience.

Q 3. What should I know before taking the OSCP?

A 3. Before you begin working on the OSCP practice labs, you should be well-versed in networking, Linux, Bash, Perl, and Python.
