Web application penetration testing is the technical assessment procedure implemented to uncover both serious and minor security flaws in the customers’ systems. There are many reasons behind companies’ decision to order web app pentests such as to check whether the information and assets belonging to their customers can be stolen by malicious actors.


Many web applications store and handle sensitive financial and contact information belonging to their users. As a result, these applications become a lucrative target for cybercriminals. Web applications are becoming increasingly complex products and that is why the types and number of vulnerabilities that can be exploited by cybercriminals are always expanding. Thus, by applying for Hacken’s web penetration testing services companies can make a solid contribution to ensuring the security of their customers.


Hacken web application penetration testing services: the value you get


Our specialists responsible for carrying out web app pen testing will instruct you on what information and in what scope you need to provide to our security experts to ensure effective execution of web application security testing. When performing web application pentesting, our experts will immediately notify you of any updates, outcomes, and required actions to keep you informed about the state of web app pentest. 


Upon completing the penetration testing of your website, our experts will provide feedback regarding the scope of identified vulnerabilities and the measures that can be taken to address them. Upon passing web application pentesting you will get to know what further security testing measures are required to ensure the ultimate security of your users.

  • Strong reputation: we deliver only high-quality web penetration testing services to clients to maintain our strong image in the market;
  • Constant improvement: we regularly integrate new information regarding web application penetration testing into our processes to keep up-to-date with security trends.


Penetration Testing Approach


The algorithm of web application penetration testing applied by Hacken security experts is based on the “OWASP Testing Guide”, the latest version of the web security standard. The competitiveness of our approach to web penetration testing is determined by the strong expertise of our security engineers. That is why Hacken can deliver web app pen testing best practices. When carrying out the web application security testing, our expert will follow the OWASP Top 10 methodology that includes the following elements:


  • Input Validation
  • Parameter Tampering
  • Session Handling
  • Information Leakage
  • Authentication, Access Control, and Authorization
  • Encryption and Certification
  • Logical Flaws
  • File Upload Functionality
  • Susceptibility to fraudulent activity and criminal attack vectors

Web Application Security Testing Methodology

The approach used by Hacken specialists to carry out web application penetration testing on clients’ requests is built on the logical flow containing several distinct but, at the same time, closely interrelated phases beginning with data collection. 


Man-In-The-Middle (MITM) proxies, web vulnerability scanners, and other open-source utilities are the tools that are actively used by Hacken specialists when performing web application security testing to estimate the security of web applications, custom scripts and programs and, as a result, determine whether the website under test is secure enough for users.


Information Enumeration

The first stage of the web app pen testing provides for identifying the data that are publicly available and specifically related to the website or application in question. The collected information can be useful for performing the next phases of web application pentesting.


Such data as application details, architecture and technology in use, network configurations, personnel and their roles within the application management structure and possible usernames, authentication formats, and passwords that may be in use are actively looked for by security engineers during the process of web application penetration testing. The quality of the web penetration testing heavily depends on the quality and quantity of the identified publicly available information.


At the next phase of the application penetration testing, any part of the web application that is publicly accessible will be assessed to identify the information demanded by an attacker, either in the files stored on the site or the web source itself. The specialists responsible for carrying out web app pentesting need to know hackers’ objectives to understand how to protect the targeted web application.


Web Application Analysis

Hacken experts will identify the ports, protocols, and services present on the IP addresses linked to the hosting web application through standard IP protocols. A combination of protocol fingerprinting, banner grabbing, and manual communication with the service will be applied during web app pentest to enumerate the ports and services and thereby enable the identification of any application protocols in use and software vendors and versions supporting the application.


Also, at this stage of web app penetration testing,  any specific infrastructure will be identified by our experts to detect any known vulnerabilities that could be exploited by malicious actors to attack the application. These include Intrusion Detection / Prevention Systems (IDPs), separate web/application servers, DNS load balancing, Web Application Firewalls (WAFs), and reverse proxies.


Vulnerability Analysis

Hacken specialists will review all identified ports, services, and web applications to detect vulnerabilities during the vulnerability analysis stage of web penetration testing. Using its knowledge of web application pentesting techniques and professional experience, the test team will create a map of the services that are present on the systems and identify serious vulnerabilities.


The vulnerability analysis stage of web application penetration testing is crucial for ensuring that the following testing will not disrupt the functioning of the service.


Application analysis provides for using a suite of testing tools and accessing the account of a valid test user to estimate issues from both unauthenticated and authenticated points of view. Typically the application penetration testing will comprise security testing of:


  • Application server (if applicable)
  • Client/server protocols and communications path
  • Client application.


The process of penetration testing of a website includes an attempt to carry out safe exploitation of application vulnerabilities to determine the extent and implications of exploitation and its potential business impact.


If our experts gain additional access via exploitation techniques used during web app pentest, they will analyze whether it is possible to utilize this access to gain further access to any other systems and services.
