Web and API Pentest

Interactive web applications are part of digital business models and have extensive rights in the infrastructure. Therefore, a check of the attack vectors is essential for your company.

What is a Web and API pentest?

A web pentest, as the name suggests, is a penetration test that focuses solely on a web or API application and not on a network or enterprise. The underlying concept andobjectives for detecting security weaknesses and strengthening defense mechanisms are identical.

Our services offer complete protection against real threats. We check your front-end as well as back-end with all common database systems and the corresponding interfaces (API). Advanced knowledge in the area of operating systems and web servers enables us to uncover deep-seated vulnerabilities.

Your Benefits

The web pentest is planned, executed and evaluated by our specially trained security engineers.

We protect your data from loss and check the compliance of defense mechanisms.
  • Compliance with industry safety standards with certification for the customer
  • Comprehensive recommendation for the elimination of the weaknesses
  • One-time verification free of charges
  • Own and constantly updated scanner software in addition to the usual commercial tools
  • Extensive research ensures that even daily weaknesses can be identified.
We carry out safety analyses based on recognised standards and guidelines.
  • We audit web applications using the OWASP Testing Guide. Our tools and procedures are able to identify the OWASP Top 10 vulnerability categories in the best possible way.
  • Our processes are adapted to the practical guidelines for pentests of the Federal Office for Information Security (BSI).
  • We have developed a comprehensive final report that provides an optimal insight into our work and its results. Pentests are conducted and evaluated according to the OWASP Testing Guide. Alignment with OSSTMM and PCIDSS is also possible upon request.

Scope

In general, the longer our security engineers examine your web applications or API, the more meaningful the results will be. If you have special requirements, we will be happy to make you an individual offer.

  • INFORMATION PROCUREMENT

    There are direct and indirect methods of search engine search and education. Direct methods refer to searching the indexes and the corresponding content from the cache. Indirect methods refer to the collection of sensitive design and configuration information by searching forums, newsgroups, and website advertisements.

  • CONFIGURATION MANAGEMENT

    The intrinsic complexity of the networked and heterogeneous Web server infrastructure, which can include multiple Web applications, makes configuration management and review a fundamental step in testing and deploying each application. Only one vulnerability is needed to compromise the security of the entire infrastructure.

  • SESSION MANAGEMENT

    One of the core components of any web-based application is the mechanism that controls and maintains state for a user interacting with it. This is called session management and is defined as the set of all controls that govern the stateful interaction between a user and the application.

  • ERROR HANDLING

    During a pentest of web applications we often encounter many error messages generated by applications or web servers. These error messages are very useful for attackers because they contain a lot of information about databases, errors, and other technological components that are directly connected to web applications.

  • IDENTITY MANAGEMENT

    In modern applications, it is common practice to define system roles to manage users and authorizations for system resources. Administrators represent a role that provides access to privileged and sensitive functions and information, while normal users represent a role that provides access to regular business functions and information.

  • AUTHENTICATION

    Testing the transport of the credentials means checking whether the data is transmitted from the browser to the server unencrypted or whether the web application uses the appropriate security measures with a protocol such as HTTPS. The HTTPS protocol is based on TLS/SSL to encrypt the transferred data.

  • AUTHORIZATIONS

    Many web applications use and manage data as part of their daily operations. With input validation methods that are not well designed or used, an attacker could exploit the system to read or write data that should not be accessible. In special situations, it may be possible to execute arbitrary system commands.

  • INPUT VALIDATION

    The most common vulnerabilities in web applications occur when user input is not properly validated. This weakness leads to almost all major vulnerabilities in Web applications, such as cross-site scripting, SQL injection, interpreter injection, local and Unicode attacks, file system attacks, and buffer overflows.

  • CRYPTOGRAPHY

    Sensitive data must be protected during transmission over the network. This data may include user data. Even if today's standard encryption is usually high-quality encryption, a misconfiguration can force weak encryption that allows an attacker to read sensitive data.

  • BUSINESS LOGIC

    Testing for errors in business logic often requires unconventional methods. When the authentication mechanism of an application is developed, perform steps 1, 2, 3 in this specific order to authenticate a user. What happens if the user goes from step 1 directly to step 3?

  • USER-SIDE VULNERABILITIES

    Client-side testing deals with the execution of code on the client, typically natively in a web browser or browser plug-in. The execution of code on the client side differs from the execution on the server and the return of subsequent content. This involves testing for all common types of cross-site scripting.

  • APIs

    Modern applications use an API to call micro services, perform actions or monitor user behavior. The design or structure of the API is often made publicly available to users. This structure allows the attacker to understand the API and use the information for further attacks.

  • Patch Management

    The term patch management describes the strategic control for the import of system updates, which are used to close security gaps in software applications that are only detected after the market launch. Outdated software packages or frameworks from external sources should always be kept up-to-date.

Final Report

We have developed a comprehensive reporting format that provides optimal insight into our work and its results. Pentests are conducted and evaluated according to the OWASP Mobile Security Testing Guide.

  • Our report is prepared according to recognized standards and includes a management summary, a technical summary and recommendations for action. The evaluation of the findings is based on the CVSS 3.0 standard.
  • Unser ausführliches Berichtsformat gibt nicht nur Aufschluss darüber, welche Schwachstellen während des Pentests identifiziert wurden, sondern auch welche Angriffsvektoren dabei überprüft wurden. Somit können Sie unsere Arbeit optimal nachvollziehen.
  • Der Abschlussbericht wird individuell erstellt und sowohl als klassisches PDF-Dokument, als auch in einem speziellem HTML-Format ausgeliefert. Im dynamischen HTML-Format können Inhalte und Schwachstellen-Funde gefiltert, sortiert und in andere Formate exportiert werden.
  • In einem gemeinsamen Abschlussgespräch besprechen wir mit Ihnen die Details des Berichts und unterstützen Sie bei Bedarf bei der Behebung der identifizierten Schwachstellen.
Pentest-Report

Procedure

Pentests carried out by us are an agile process and are carried out in close consultation with the customer.

Kick-Off

The preparation of the pentest takes place in the context of a kick-off meeting with the technical and organizational responsible persons of your company. The framework conditions to be tested are specified, necessary user accounts and access routes are agreed, contact persons and escalation routes are defined and the pentest is discussed in detail together.

Research

Our analysts try to collect as much information as possible. Based on this information, analysis strategies are developed to identify possible attack vectors. These attack vectors are then examined for vulnerabilities in extensive tests.

Exploitation

In this phase, an attempt is made to actively exploit the identified vulnerabilities in order to gain access to the target systems. Depending on the service or technical environment, our pentester writes new exploits or uses existing ones. Potential vulnerabilities can turn out to be false positives. Only verified vulnerabilities are included in the final report and classified according to their criticality.

Report

You will receive a comprehensive final report consisting of a Management Summary and a Technical Report. The criticality of the weak points and recommendations for action are described in detail.

Remediation (Optional)

In this phase, the identified weak points are eliminated by your company. If required, you will be supported by our experienced security engineers.

Nachprüfung (Optional)

After the remediation you have the opportunity to have us carry out a follow-up check. Here we check the effectiveness of your measures and adjust the result report.

Abschlussgespräch (Optional)

In this final discussion, all critical points in the results report are discussed and all final questions clarified.
