What is Web Application Penetration Testing?

Web Application Penetration Testing, also known as Web Application Security Testing, identifies and addresses vulnerabilities which may be present inside an organisation’s web application. Spider Sec’s consultants will follow industry-standard methodologies to discover vulnerabilities which may have been introduced into the web app’s code, server configurations or business logic flow. A pen tester systematically assesses the application to uncover vulnerabilities through reconnaissance, vulnerability analysis, exploitation, and reporting.

Vulnerabilities are presented back to clients in reports which are structured to be accessible to both technical and management audiences, and include risk ratings, potential attack scenarios and remediation steps.

Brief Overview of a Standard Test:

Check for secure SSL Configurations.
Injection flaws.
Authentication weaknesses.
Poor session management, session fixation.
Broken access controls.
Check for misconfigurations of the webserver and database.
Input validation problems.
Flaws in application Business logic.

Key Benefits Of A Web Application Penetration Test

A web application penetration test is an essential security assessment that empowers organizations to proactively defend against evolving cyber threats. By simulating real-world attack scenarios, a penetration test uncovers security vulnerabilities and weaknesses within your web application, allowing you to take targeted action before malicious actors can exploit them.

Some of the key benefits of conducting a web application penetration test include:

Identifying vulnerabilities such as SQL injection, cross site scripting (XSS), and other security flaws that could be exploited to gain unauthorized access to sensitive data.

Strengthening your security posture by addressing discovered vulnerabilities and improving access control mechanisms, reducing the risk of successful web application attacks.

Mitigating the risk of data breaches and minimizing potential financial loss or reputational damage by proactively identifying and remediating security vulnerabilities.

Ensuring compliance with industry standards and regulations like PCI DSS, which require regular security assessments and the identification of potential vulnerabilities in web applications.

Receiving actionable recommendations for remediation, enabling your security team to prioritize and address vulnerabilities found during the assessment efficiently.

Enhancing your organization’s ability to detect and respond to threats, ensuring that your web application is resilient against both common and advanced attack techniques.

By investing in a web application penetration test, organizations can identify vulnerabilities before they are exploited, protect sensitive data, and demonstrate a commitment to robust security practices.

A Web App Penetration Test will help our clients:

Comply with GDPR and other regulatory bodies which require regular penetration testing.
Provide evidence to your clients or supply chain that your organisation take proactive steps towards securing your data.
Develop in house security awareness of common vulnerabilities for developers. Making them proactive in securing their future applications.
Reduce the risk of being successfully attacked by cyber criminals.

Our Methodology

Our consultants are all certified with at least Red Team Operator or OSCP certificate. We follow the industry-standard OWASP Top 10 web application testing methodology and OSSTMM. Alongside this, we use our own in-house methodologies which have been tried and tested during our own careers.

Case Study

To demonstrate how our own methods deviate from others please see the following blog posts, wherein we went beyond just using scanners such as WPscan against our clients’ WordPress site. During the engagement when the scanner returned data telling us all plugins were up to date and reported 0 vulnerabilities, we used security tools to gather additional information about software involved.

We spun up our own lab and went in search of 0 days inside their installed plugins. Reviewing the source code and analyzing the software environment helped identify potential exploits. The team attempted to gain access to the application by exploiting vulnerabilities, and gaining access provided further insight into the security posture. Secure coding practices are essential to prevent such exploits. Because we genuinely care about our clients’ security; we are willing to go above and beyond the standard methodologies to secure the web.

Tools Used for Penetration Testing

Penetration testing relies on a suite of advanced tools and techniques to thoroughly assess the security of web applications. These tools help penetration testers gather information, identify vulnerabilities, and exploit weaknesses to evaluate the true risk to your systems.

Some of the most widely used tools in web application penetration testing include:

Burp Suite: A powerful platform for web application security testing, Burp Suite enables penetration testers to perform vulnerability scanning, analyze traffic, and exploit discovered vulnerabilities within web apps. We utilize this tool most during a web application penetration test, allows us to intercept and modify requests to and from the web application to manually find vulnerabilities that scanners often miss.

OWASP ZAP: As an open-source web application security scanner, OWASP ZAP helps identify potential vulnerabilities and weaknesses by automating many aspects of the security testing process.

Nmap: This network scanning tool is essential for discovering open ports and services on the target system, providing valuable reconnaissance data that can inform further testing.

SQLMap: Specializing in SQL injection testing, SQLMap automates the process of detecting and exploiting SQL injection vulnerabilities, helping testers assess the risk to sensitive data stored in databases.

Metasploit: A comprehensive penetration testing framework, Metasploit offers a wide range of tools for vulnerability exploitation, privilege escalation, and post-exploitation analysis.

By leveraging these tools, along with specialized techniques and methodologies, penetration testers can conduct in-depth security assessments, identify vulnerabilities, and provide organizations with the insights needed to secure their web applications against sophisticated attacks.

Penetration Testing Engagement Process

Spider Sec has tried to make the scoping process as easy as possible. Defining the scope is a critical step in planning effective penetration tests, ensuring that all relevant systems and testing types are properly addressed. We have created a quoting form which will price your project based on your requirements. If you are happy with the quote, send it to us, we can book in a quick call then we will send over our authorisation forms and SOW to be filled out.
We can then schedule the engagement and ensure all prerequisites are in order.

Scoping

Spider Sec has tried to make the scoping process as easy as possible. Defining the scope is a critical step in planning effective penetration tests, ensuring that all relevant systems and testing types are properly addressed. We have created a quoting calculator form which will price your project based on your requirements.If you are happy with the quote, reach out over via the contact form and will setup a call to fully scope the engagement.
Finally will send over our authorisation forms and SOW to be filled out. Finally, we will schedule the engagement and ensure all prerequisites are in order.

Engagement

On the scheduled date you will receive an email before the penetration test begins. During the engagement, if any high or critical risk vulnerabilities are discovered, or other significant risks to your web application, you will be informed ASAP.

Reporting

Once the engagement is completed we will write up our discoveries into an easy to digest report with remediation steps and risk ratings.

Retest

After you have digested the report if you wish to book a retest please let us know. We are happy to retest high and critical risk vulnerabilities for free.
