Organizations must ensure that their networks are protected and updated in order to protect consumer data. Hackers have made it possible to hack into organizations' systems in an unethical way and compromise security controls in order to achieve their malicious goals.


Security threats are made possible by the complexity of software that is being developed and the fact that there are billions of connected devices to them via the internet. Intruders can gain access to large amounts of data and cause organizations to lose customers or money. Businesses must use a comprehensive approach for fool proofing their systems in order to be secure and resilient to competition. There are many standard security techniques that can be used. One of these specialized techniques is penetration testing. It aims to identify any loopholes in the system through which an attacker could gain access to critical data. This ultimately leads to businesses suffering monetary losses and losing customers to other competitors.

An introduction to penetration testing

Penetration testing covers both the software and hardware of a fully functional system. This helps to identify weaknesses in the system that attackers may be able exploit.


The system's configuration is also checked to ensure that there are no compromises. Penetration testing, also known as ethical hacking, can be done manually or automatically. Different scenarios can be used to simulate breaking into the system and obtaining accurate results.


What is Penetration Testing?

Penetration testing is done in a controlled environment, where possible loopholes can be identified and fixed before attackers exploit them. An attacker can access the system through any loopholes and use the data to carry out malicious activities.


Pen-Testing Requirements - The Five Rs

Organizations should have realistic requirements when conducting penetration testing in controlled environments. The ethical hacker will simulate a real-life scenario where the system could be compromised. Before performing this type of activity, employees must be aware of their privacy rights. These five requirements are necessary for pen-testing to begin.


Respect: All people involved in the pen-testing process should be treated with respect. They should not feel pressured or made uncomfortable.

Restriction: People must behave normally, and not change the way that they live their daily lives.

Reliable: Pen testing should be reliable, but not disrupt the company's regular work.

Repeatable: Pen-testing can be repeated for exact results, just like other methods of testing. The results should not be affected by changes in the environment.

Reportable: It is important to monitor and improve the process in order to increase its effectiveness in the future. Logging should be kept for all important actions. Test results should also be recorded in order to aid with decision-making.

Different types of penetration testing

These types are the most popular in practice:


Black Box Testing: Black box testing allows us to have an executable program of the system, but we are not aware of its internal workings or environment. We input data, analyze the result, and then compare it to the expected output.


White Box Testing: This type of testing requires that the tester has complete knowledge about the system. Experts must analyze the code step-by-step to understand how the system works. Then, based on this knowledge, they will prioritize the test cases in order to find vulnerabilities at all levels.


Phases of Penetration Testing

Information gathering: It is important to gather all information about the server before testing a web app. This phase involves determining the correct domain and subdomains that are linked to the parent domain. We also need to determine if firewalls have been installed for this particular server. WAFWOOF is one of many tools that can detect the presence or absence of firewalls.

Scanning: This phase allows us to determine which service is being run on the server, and which port. We use NMAP and Pressler PRTG as scanners.

Finding a vulnerability: A penetration tester uses a variety of tools to discover any vulnerabilities in the system. These tools can identify potentially dangerous files and programs and verify for loopholes.

Exploitation: After identifying a vulnerability, the pen-tester will then attempt to exploit it by remote accessing the server. Experts usually use Metasploit to accomplish this.

Reporting: This is the final phase of all testing methods. A report is generated and the next course of action is determined. Reports should not be lost or stolen and are therefore vulnerable to attack. They should be well protected.

It is crucial that test results are effective enough to identify potential vulnerabilities and eliminate them from the system. This is how security and penetration testing are distinguished.

Testing tools for penetration

Penetration testing can be done with many tools. While no single tool will help an organization accomplish its goals, a combination of several tools can be helpful in finding loopholes in the system. We have listed a few of these tools:


Nmap: Also known as network mapper, Nmap is a free open-source tool that allows experts to scan the system and find vulnerabilities. NMAP is a tool that allows us to scan ports and determine if they are open or closed.


Issue is one of many tools that can be used to identify vulnerabilities and malicious activity in the system. It is free for non-enterprise users and individuals to use.


Metasploit is a framework for penetration testing. This tool allows us to develop, test and exploit system code. You can use it both open-source and commercially.


Benefits and challenges

Organizations can use penetration testing to protect their systems against any attackers attempting to compromise them. Pen-testing, in short, is a legal way to compromise the system's security by gaining an attacker's mind.


There will always be improvement opportunities, but these challenges can be used to improve existing processes and achieve higher quality. These are just a few of the many challenges:


A limited timeframe: Organizations often compromise the testing phase when they are short of time. This creates unnecessary pressure for the team. Penetration testing is time-consuming, so it can be a challenge to complete within a short timeframe. This could leave the system vulnerable to attacks.


Security: A system cannot be secured 100%. The stability of the system is often determined by the skills of professionals.


Automation: To reduce time and effort, a test automation framework is possible. Expert testers can help with automation pen-testing.



Organizations can reap the benefits of penetration testing in many ways. They can prevent monetary losses, preserve their brand reputation, comply with regulations and statute rules, eliminate potential risks and so forth.


Penetration testing can be used to identify and eliminate security loopholes in systems. Pen-testing is an important part of any organization's security policy. It should be done on a regular basis to improve stability.
