Cyber-Security is a huge concern for businesses and individuals alike. With so much information stored online, it’s important to make sure that your data is safe and protected. One way to do this is through penetration testing. Penetration testing, or “pentest,” is the process of attempting to exploit vulnerabilities in a system in order to determine how secure it is. In this blog post, we will discuss how pen testing is done and what kinds of vulnerabilities can be found. Stay safe out there!
How Is Pentesting Done?
There are a few different ways to pentest a system. The most common is called “black box” testing. In black-box testing, the tester has no prior knowledge of the system other than what is publicly available. This type of test is usually used to find vulnerabilities that can be exploited from outside the network.
Another approach is “white box” testing. In this type of test, the tester has full access to the system and knows all of its vulnerabilities. This type of test is used to find vulnerabilities that can be exploited from within the network.
Finally, there is “grey box” testing. This type of test falls somewhere in between black-box and white-box testing. The tester has some knowledge of the system but not as much as in white-box testing. This type of test is used to find vulnerabilities that can be exploited from both inside and outside the network.
What Vulnerabilities Can Be Found?
There are a variety of different types of vulnerabilities that can be found during pen testing. The most common are:
Vulnerabilities in the operating system: These are vulnerabilities that exist in the software that runs the system. They can be exploited to gain control of the system or to steal data.
Vulnerabilities in applications: These are vulnerabilities that exist in the software installed on the system. They can be used to steal data or to take control of the system.
Cross-site scripting (XSS): This is a type of vulnerability that allows an attacker to inject malicious code into web applications. The injected code can be used to steal data or take control of the system.
SQL injection: This is a type of vulnerability in databases that allows an attacker to execute arbitrary commands on the database server. If this happens, they may be able to steal data or take control of the system.
Penetration testing is a valuable tool for assessing the security of your systems. By identifying and exploiting vulnerabilities, pen testers can help you to improve the security of your systems and protect your data. Stay safe out there!
