A very warm hello!
A hacker attack can be not only harmful to business, but also devastating. It is therefore essential that IT security measures are always up-to-date and are constantly expanded, improved or adapted. A penetration test is an important tool for this.
What is a Pentest?
A penetration test simulates a cyberattack on your company. IT specialists, also called ethical hackers or penetration testers, carry out targeted attacks on the IT infrastructure in order to test existing security mechanisms and find out how easy they are to bypass. IT networks and systems are checked for security-relevant gaps and vulnerabilities. At the end of a pentest, a report is created which summarizes the results and gives recommendations for action. So that the existing vulnerabilities can be fixed as quickly as possible before a real attack occurs.
Why is a pentest important?
It is a very good way to detect vulnerabilities in your own IT infrastructure, i.e. to take the position of a hacker and simulate a real attack. Security vulnerabilities are detected early on and can be fixed before hackers use them to gain access. A pentest provides concrete recommendations for action through a final report for measures that optimize IT protection. In this way, the systems and thus also sensitive data are better protected. Because a data theft can have devastating consequences for a company.
A cyberattack can not only have devastating financial consequences or damage a company’s reputation. In many industries, such as finance or healthcare, there are also strict regulations for IT security. If these are not respected, large fines can be imposed. Individuals such as managing directors can also be held personally liable. It is therefore all the more important that the IT infrastructure is regularly reviewed and adapted. And for this, a pentest is an optimal solution.
It is also advantageous that an outsider who has little to no previous knowledge of the current security situation in the company and thus has the same level of knowledge as a real hacker. Even if this is not always the case. According to studies, it is usually the case that the cyberattacks that cause the greatest damage were carried out with the help of insiders or even from within. Employees are recruited or insiders disguised as craftsmen insert malware via USB sticks, gain access to the system through unlocked computers or use various other ways to gain access. Social media platforms are also a popular means of obtaining information. In the meantime, the attacks take place in such a way that first research is carried out, people are recruited or smuggled in, and then targeted.
What types of pentests are there?
There are different types of pentests. Depending on the objective and scope, there is a suitable type. We would like to discuss the three most common ones here and briefly explain them:
- Black box test:
In this case, the people who perform the pentest have no information or prior knowledge of the company, system or network infrastructure. This simulates the situation where a hacker tries to get into the IT infrastructure without any prior information.
- White box test:
Unlike the black box test, the penetration tester has comprehensive information about the actual situation and knows, for example, source codes of applications or the network architecture. This has the advantage of a full view of all systems, so that particularly deep security gaps in the code or the configuration are discovered.
- Grey Box test:
In this case, the penetration testers have partial insights and information from the company. Thus, it is possible to simulate a scenario that is most realistic, since no clear distinction is drawn between internal and external threats. In addition, it is possible to search for targeted vulnerabilities that do not influence the test result by too much information.
How does such a pentest work?
After determining what the objective is and what type of pentest to perform, the following steps are taken:
- Planning and preparation
- Vulnerability analysis
- Attack simulation
- Reporting
Once the pentest has been successfully carried out and a report has been produced, the first recommendations for action can be implemented in order to optimize the IT security systems. If there is not enough internal capacity for implementation, these can usually be purchased by the Pentest provider. Also products that increase the safety standard.
Conclusion
A penetration test is an indispensable instrument in the IT security sector. It enables companies to review the current state of their IT security and identify vulnerabilities early on before real attackers can exploit them. Proactive action can be taken and hacker attacks can be optimally prevented. This is how companies protect their data, business operations and reputation.
