Penetration testing, also known as pen testing, is the practice of testing a computer system, network or web application to find vulnerabilities that an attacker could exploit. It’s a legal and ethical way to assess the security of a system, and is often used by organizations to help improve their security posture.
Penetration tests can be conducted in a number of ways, depending on the goals of the test and the type of system being tested. Some tests are designed to simulate a real-world attack, while others may focus on specific system vulnerabilities. The most important part of any penetration test is the preparation and planning stage, where the goals and objectives of the test are defined.
Once the goals of the test have been defined, the next step is to select the right tools and techniques for the job. This will vary depending on the system being tested and the type of test being conducted. For example, a test of a web application might use different tools than a test of a network.
After the tools have been selected, the next step is to conduct the actual test. This will involve using the selected tools to attempt to find vulnerabilities in the system. If any vulnerabilities are found, they will be documented and reported to the organization.
The final step in a penetration test is to debrief the organization on the findings. This is important in order to help the organization understand the risks that were identified and to help them improve their security posture.
Why does pen testing matter?
Penetration testing is a process of testing a computer system, network, or web application to find vulnerabilities that an attacker could exploit. These tests are usually performed by ethical hackers, also known as white hat hackers, who use the same methods and tools as an attacker would use, but with permission from the owner of the system being tested.
The goal of penetration testing is to identify and then exploit vulnerabilities in a system in order to gain access to sensitive data or to disrupt normal operations. By doing so, ethical hackers can help organizations to understand the risks they face and to take steps to mitigate those risks. Penetration testing can be an important part of an organization’s security strategy, as it can help to identify weaknesses in systems before an attacker does.

By finding and fixing vulnerabilities, organizations can make it much harder for an attacker to successfully exploit them. Organizations should carefully consider their needs and objectives when planning a penetration test, as well as the risks involved. They should also ensure that they have the necessary permissions in place before starting the test.
How much does a penetration test cost?
The cost of a penetration test depends on a number of factors, including the size and scope of the test, the level of expertise of the testers, and the amount of time required to complete the test. In general, however, a penetration test can cost anywhere from a few hundred to several thousand dollars.
One of the main factors that will affect the cost of a penetration test is the size of the target system. A smaller system will generally be less expensive to test than a larger one. This is because a smaller system will have fewer potential vulnerabilities and will require less time to test.
Another factor that will affect the cost of a penetration test is the level of expertise of the testers. Testers with more experience and expertise will be able to find more vulnerabilities in a system and will also be able to exploit them more effectively. This means that they will generally charge more for their services.
Finally, the amount of time required to complete a penetration test will also affect the cost. A shorter test will obviously be less expensive than a longer one. However, it is important to note that a shorter test may not be as comprehensive as a longer one, and therefore may not be as effective in identifying all of the potential vulnerabilities in a system.
