Application Penetration Testing

Test your application’s security before someone else does.

Finding, fixing, and fortifying.

Many organizations rely on vulnerability scanning to assess the security of their Internet-exposed applications. While such scans can highlight some known weaknesses, application penetration testing provides a more realistic view of how applications are equipped to withstand an attack in a real-world scenario. Identifying vectors that malicious actors can exploit is critical to improve your organization’s cybersecurity profile.

The Open Web Application Security Project’s top application security risks form a foundation for application penetration testing:

  • SQL Injection — Hackers alter the SQL statements used in an application’s backend. These SQL injection attacks result in the database executing commands that provide unauthorized access to data.
  • Cross-Site Scripting (XSS) — Applications that execute scripts in the browser receive and run untrustworthy requests. Hackers use those malicious scripts to perform actions like defacing websites, hijacking cookie sessions, or redirecting unsuspecting users to websites where they can steal their information.
  • Broken Authentication and Poor Session Management — Applications typically invalidate cookies for a session once a user closes a browser or logs out of a website. If that invalidation doesn’t happen, and the session remains open, hackers can hijack those still-valid cookies and obtain the sensitive information they contain.
  • Security Misconfiguration — Developers who fail to properly define the security configuration for a web application and related components leave it vulnerable to unauthorized access by a hacker. Areas they like to target include URLs and input fields.
  • Insecure Deserialization — When data under the control of a user becomes deserialized by an application, attackers can manipulate it by passing harmful information into the source code.
  • XML External Entities Injection (XXE) — Attackers interfere with how an application processes XML data. Attackers can then view files on the server and access back-end systems on which the web application relies.
  • Broken Access Controls — Users may end up with access to restricted resources or can perform functions outside of their designated roles. That leaves an organization vulnerable to an attack from the inside.
  • Vulnerable Components — Developers may use components in their website that may be out of date, susceptible to attack, or unsupported. Hackers gain an opening through which they can steal sensitive information or hijack an organization’s systems.

No stone left unturned.

Rule4 performs a variety of application security testing services, usually based on the Open Source Security Testing Methodology Manual (OSSTMM) and the OWASP methodologies. We bring a wide array of unique skills and certifications to the table, and whether we’re testing an end-user application, API, or microservice, we analyze everything from the business logic to browser-resident code, from subsystems to databases.

We’ve got your back!

We’ll help find and remediate any weaknesses in your application.
