What is Web Application Penetration Testing [Ultimate Guide]

73% of successful breaches in the corporate sector occurred in penetrating web applications through their vulnerabilities. As more and more companies migrate to the cloud, the above statistic is becoming even more alarming. It is important to ensure that your data is safe and secure to ensure that your business is safe from malicious actors.

Web application penetration testing ensures that you are aware of weaknesses before a malicious actor takes advantage of it. This gives you an edge over your competitors and helps you build trust amongst your customers. A constant focus on security is an added feather on your cap.

This articles focuses on web application penetration testing and helps you better understand the different facets of conducting web application penetration testing in your organization to ensure better overall security posture.

What is web application penetration testing?

Web application penetration testing is an essential part of web application security. It is the process of simulating hack-style attacks to identify potential vulnerabilities in web apps using simulated attacks.

It helps organizations comply with security standards and regulations such as PCI-DSS, HIPAA, GDPR, etc. Web application testing should be performed regularly and periodically to ensure that the web applications are secure and up-to-date.

The purpose of these web application penetration testing is to uncover and mitigate security risks to improve the applications’ overall security posture before they can be exploited by malicious actors. This will ensure that your data is safe and secure while ensuring that your brand is dependable by customers’.

What are the benefits of web application penetration testing?

Web app penetration testing is essential as it helps in determining the security posture of the entire web application including the database, back-end network, etc. Moreover, it suggests ways to strengthen it.

Here is the list of some common objectives for performing web applications penetration testing:

• Identify security loopholes in web applications
• Verify the effectiveness of the existing security policies and controls
• Ensuring compliance such as PCI DSS, HIPAA, etc
• Check the configuration and strength of components exposed to the public including firewalls.

What is the process of penetration testing for web applications?

The usual process of penetration testing for web applications involves a vulnerability scanner which is used to probe and detect loopholes in your security such as misconfiguration, unpatched software, SQLi, cross-site scripting, etc.

Then manual pentesters enter your system to

a) confirm the authenticity of the vulnerabilities found by the scanner and

b) look for more complicated vulnerabilities like business logic errors, and payment gateway errors.

Once the testing and exploiting are done the pentesters prepare a pentest report containing the details of all the tests performed, vulnerabilities found, information about their severity, and probable solutions. You can engage your in-house security team or look for web application penetration testing services.

Let’s talk

Get started

What are the different types of web app penetration testing?

Depending on your business requirements, you can conduct internal or external penetration testing.

1) External Penetration Testing

External Pentesting involves simulating attacks on the live website/web application. This kind of penetration testing runs on the Black Box testing methodology. It is usually done by a third-party pentest provider.  

During this, the pentester only gets the list of the organization’s IPs and domains and using just IP & domains the pentester tries to compromise the target just like the real-world behavior of malicious hackers. 

This kind of testing provides a comprehensive view of the effectiveness of your application’s security controls that are publicly exposed since it includes testing servers, firewalls, and IDS.

2) Internal Pentesting

Sometimes the organization overlooks the need to pentest the web application internally. They feel that no one can attack from inside an organization.  However, this isn’t the case anymore. After the external breach, internal penetration testing is done on a web application to identify and track the lateral movement of the hacker from the inside.

Internal Pentesting is done for a web app hosted on the intranet. Thus, it helps in preventing attacks due to the exploitation of vulnerabilities existing within the corporate firewall.

What steps are used to perform a web application pentest?

There are four ideal phases in which web application pentesting can be performed:

1) Planning Phase

During the planning phase, a number of important decisions are made that directly impact other phases of penetration testing. It includes defining the scope, timeline, and people involved among other things. The organization and the provider of web application penetration testing services must agree on the scope.

Most importantly during defining the scope of the security assessment, there are various things that are considered before going to the next phase of testing. These may include application pages that need to be tested, deciding whether to perform internal or external testing or both, to name a few.

It is also crucial to define the timeline for the whole process. This ensures that the assessment doesn’t drag out and timely security controls can be put into play to strengthen the defense for your application.

2) Pre-Attack Phase

In this phase, the reconnaissance is done which is important for paving the way for the next phase of testing. Especially, it includes looking for Open Source Intelligence (OSINT), or any other information available publicly that can be used against you.

We can perform port scanning, service identification, vulnerability assessment, etc in this testing phase. To accomplish this you can use tools such as Nmap, Shodan, Google Dorks, dnsdumpster, etc.

As we all know, due to the growing adoption of social media among the organization’s employees, hackers can easily fool employees and extract or guess passwords they use for their social media, threat actors do this by carrying out social engineering attacks to target those organizations that have weak internal security posture implemented.

3) Attack Phase

During the attack phase, the pentester tries to exploit the vulnerabilities found in the last phase. They try to go one step further by identifying and mapping the attack vectors. 

In an attack phase, the pentester gets into a web application’s internal structure and tries to compromise the host. 

This may involve social engineering attacks, physical security breaching, web application exploits, phishing employees or CXOs of an organization, etc. 

4) Post-Attack Phase

After the penetration testing is complete, a full detailed report is generated. This report can vary from organization to organization or the type of application that is pen-tested. 

But generally, the penetration testing report includes a list of vulnerabilities, an analysis of the finding, proposed remediations, and a conclusion. Apart from that, the pentester is also responsible for restoring the systems and network configurations to their original states in the post-attack phase.

Should You Consider Automated or Manual Pentesting?

You can perform web application penetration testing either manually or automated or both. Automated pentesting helps in bringing up speed, and efficiency increases coverage, and several other benefits. On the other hand, manual pentesting helps in finding the vulnerabilities related to Business Logic.

It helps in removing false positives generated from the automated scanning. Therefore, it is always good to perform both of them to bring out the best of both worlds.

These false positives can also be marked to be excluded from the subsequent scans.

Wrapping Up

Web app penetration testing plays an essential role in the Secure Software Development Lifecycle (SSDLC), helping in developing a secure and flaws-free web application. It ensures that the end-users are safe from cyber attacks like data theft and exposure of sensitive information. 

It is always best to perform a comprehensive vulnerability assessment and penetration testing (VAPT) for your web application before or after pushing it into production in order to identify the direct threats to your website/web application and ultimately to your business. Additionally, doing the VAPT scans for your web application on regular basis is a best practice to protect it from emerging cyber threats and possible zero-day exploits and attacks.
