Comprehensive Penetration Testing of Web Applications.

Today, web application security has become a key element for any company operating in a digital environment. Web applications are often exposed to various types of threats that can lead to data breaches, financial losses and loss of customer trust. Therefore, web application security testing is essential to ensure protection against potential attacks and threats. We present a comprehensive overview of web application penetration testing, which aims to identify and eliminate potential security vulnerabilities. The goal of these tests is not only to detect vulnerabilities, but also to understand how an attacker could exploit them and provide recommendations for remediation.

Service Description:

Our service covers detailed testing steps, including information gathering, application logic analysis, data validation testing, session management, authentication, access control, data processing, cryptography and error handling. The methodology is based on OWASP recommendations.
Web application penetration testing will include the following:

Stage 1 – Gathering information

• Obtain additional information using google hacking techniques,
• Identification of the version of the software in use,
• Review the vulnerability database to verify the existence of vulnerabilities for identified software/library versions,
• Overview of features and application security, including but not limited to: verification of the level of application client session (TLS) cryptographic security, analysis of user authentication methods, identification of input validation methods,
• Application review to: identify application architecture and logic (spidering), preliminary verification of input validation, analysis of user session management methods.

Stage 2 – Security Tests

• Analysis of application logic (analysis of loss of integrity confidentiality and availability of processed data, accountability of user actions),
• Testing the effectiveness of input validation and output encoding (including attempts at “Cross Site Scripting” attacks, “SQL Injection”, “LDAP Injection”, “XML Injection”, “XPATH Injection”, “directory traversal” attempts, system command invocation attempts, memory buffer overflow attempts),
• Analysis of user session management mechanisms (including, but not limited to, identification of session management scheme, verification of how session IDs are transferred, manipulation of session IDs, analysis of session ID protection methods, verification of session duration configuration, session takeover attacks, verification of additional protection mechanisms defending against attacks such as “Cross-site Request Forgery”),
• Verification of authentication mechanisms (e.g., use of default, easy-to-guess passwords, attempts to forcibly/verbally crack passwords, attempts to circumvent authentication scheme, security analysis of password reminder/reset function, verification of effectiveness of
  application logout function),
• Analysis of access control mechanisms (including identification of the access control model, analysis of the effectiveness of access control through vertical and horizontal privilege escalation attempts, i.e. direct access to objects, functions and URLs, attempts to list directory contents, verification that server responses do not contain redundant data),
• Verification of data processing and storage mechanisms (including analysis of the operation of browser cache mechanisms, verification of mechanisms for protecting locally stored data, analysis of data transfer methods between the application and the server and additional application components, e.g. Java applet, COM plug-ins),
• Analysis of cryptographic solutions (including verification of the correctness of the implementation of cryptographic solutions),
• Denial of service attacks (including analysis of the possibility of blocking other users’ accounts, attempts to overflow the memory buffer, attempts to exceed the limits of resources available to service users),
• Analysis of error handling mechanisms (including verification that error messages do not reveal redundant information, verification that the occurrence of an error does not allow escalation of privileges, attempts to manipulate error messages),
• Verification of HTTP protocol configuration (including analysis of HTTP methods used, analysis of the presence of headers regulating the operation of security-related mechanisms, e.g. prevention of clickjacking attacks, analysis of the implementation of HSTS, CSP, CORS),
• Analysis of SSL/TLS protocol implementations (evaluation of cipher suites used, analysis of SSL/TLS connection parameters configuration, verification of certificates used, identification of additional security mechanisms such as HTTP Strict Transport Security).

Features and Specifications:
