![]() ![]() ![]() To which other network systems can access be extended?Īt this stage, the aim is to check whether access can be maintained permanently (persistent).How long does such an attack go unnoticed?.What data can be extracted or manipulated?.Which areas have become vulnerable as a result of the access?. ![]() If access is successful, the test has the task of exploring all penetration possibilities because this is exactly how cyber criminals would proceed. The goal is now to gain access via the vulnerabilities found in step 2. In the third phase of a pentest, the systems are bombarded with everything that was defined in the test design. The code is observed at the level of the individual applications. Precise documentation of the procedure is particularly important here. This phase starts the search for one or more vulnerabilities that allow access. These are aggressiveness, scope, information base, approach, technique and starting point. The BSI offers a scheme to classify six important test criteria more precisely. The design of the test is developed using this information. Objectives: What results should the pentest deliver?.Methodology: Which techniques and tools should be used for the penetration test?.Introduction: Service providers get an initial overview.In the first phase, the pentest is designed – specifically for the individual customer. Here you can find a detailed guide from the Federal Office for Information Security (in German). How does a penetration test work?Įvery service provider probably has its own procedure, but there are typical phases and frameworks that are used in the industry. This allows the team’s ability to react to an incident, for example, or test the execution of a response plan under real conditions. The difference to the blind test is that the responsible IT specialists in the company are also not informed. This model is suitable, for example, for obtaining an objective assessment of your own IT security from a third party with expertise.Īnother variant is the double-blind test. This allows the IT security experts to react to access attempts in real time without knowing the penetration tester’s exact approach beforehand. The service provider receives the name and consent of the company, but no further input. This method does not require any precise agreements. This also includes targeted overloading of the external connection through DDoS attacks. It simulates an attack by hackers who only have access to the company’s external website and the systems used via the internet. The test therefore assumes an attack using data that is available to employees. This type of penetration test analyzes what happens if employee data is stolen or a so-called inside job is carried out. What types of pentests are there? Internal pentest The non-profit OWASP Foundation offers guidelines in the field of web applications. Building security systems, building control systems.Telephone systems, wireless networks (WLAN, Bluetooth).Network interfaces such as routers, gateways, switches.Packet filters, virus scanners, firewalls.Database servers, web servers, mail servers, file servers, other storage systems.Pentests can be carried out for many IT applications: Security scans: automatic tests where the results are verified manually, but there is no standardized scheme.Vulnerability scans: automatic tests without individual customization.Penetration tests should be distinguished from similar terms in the field of IT security: Configuration errors and vulnerabilities are made visible through intensive attack attempts. Typical test areas are security barriers such as a web application firewall, web-based applications, containers, their interfaces (API) and servers. The scope and depth of a professional IT expert’s penetration test can vary greatly depending on the company. However, the elimination of these deficiencies is not part of the penetration testing, but is usually the responsibility of the commissioning company. The aim of the test is to minimize the risk of cyberattacks through new knowledge because the results provide information about deficiencies in IT security. A pentest is designed to examine a client’s system (network, server, computer) for possible vulnerabilities by simulating unauthorized access.Īccess to sensitive data is a particular consideration here. Why do you need a pentest?Įvery unauthorized intrusion is referred to in technical jargon as a penetration. As such, it is the legal counterpart to a criminal hack. In the field of IT security, a penetration test, or pentest for short, is a desired, commissioned test for vulnerabilities in IT infrastructure. ![]()
