What is penetration testing? Why is it necessary?
Penetration testing allows you to prevent possible attacks by malicious people to sabotage your company's IT activities. This test determines the strengths and weaknesses of your system. In addition, it allows to avoid possible attacks before these attacks occur. This penetration test, also known as Pentest, is performed by authorized and professional employees by performing a preliminary scan of the system within the framework of legal permissions. This test specifically aims to reveal the weak points of your system.
After the weak points are exposed, it is aimed to take the necessary security measures by foreseeing what kind of attacks these points may be exposed to and how your system may bypass the security protocols. What does offensive-defensive mean and how does pentest stick? In this article, we will share with you in detail those who are curious about the topics mentioned.
What does offensive-defensive mean?
Cyber security includes different sub-branches. One of these sub-branches is defined as Offensive Cyber Security. Offensive Cyber Security is also known as Red Team. In Offensive Cyber Security operations, it is aimed to infiltrate a system and find the vulnerabilities there.
The offensive cyber security specialist should have some extra competencies apart from the competencies of a normal cyber security specialist. Some of these trainings are as follows:
Network penetration testing training
Mobile app hacking training
Web application hacking training
Practical penetration testing training
Wireless network hacking training
Offensive cyber security specialists can have the necessary competencies by taking various trainings.
The way cyber security companies work varies according to the employees they have. Companies that focus on offensive or defensive cyber security also have different sub-branches. Each of these sub-branches has different ways of working. The way cyber security companies work varies according to the sub-branch they concentrate on. In addition, the defensive is also called the blue team, which covers more of the defensive side. It is also defined as the party that knows what the attackers can do and takes measures against them.
How to do web pentest step by step?
Pentest or Penetration test is an extremely important type of test. We carry out most of our work in the digital environment. For this reason, the security of websites and applications is of great importance. In case of any security weakness; Our personal information, account information, internet usage information may be captured by third parties. The work done to detect and close the security vulnerabilities of websites and applications is called pentest. The penetration test steps are as follows:
Goal Setting:
The purpose of target setting in the penetration test; It is considered as determining the targets of the penetration test to be carried out and the systems where the tests will be carried out.
Data collection:
Passive studies are carried out primarily for the target determined in the scope. In the next step, the infrastructure used by the system where the penetration tests will be carried out, the programming language used by the developer, the functions of the related systems and what kind of operations can be performed, and tests are performed using this information in the next vulnerability detection step.
Security bug:
In the first stage of vulnerability detection, a general scan is made about the system using automated tools. With these tools, information such as which service is running on which port of the system is obtained. Thus, if there is a security vulnerability in the obtained version information, it is directly detected.
Planning:
Necessary research and planning is done to eliminate the vulnerability found in the previous step. In line with this planning, the processes are implemented and observed step by step.
Reporting:
A summary of the operations applied in the previous step is prepared. Measures to be taken to eliminate potential risks that may occur, which systems may be affected and the effects of this are also reported.
Cleaning:
If the exploit has made any changes to the system, it will be restored and the created users will also be deleted.
