In today’s digital age, businesses face increasing cyber threats, making protecting web applications a top priority. Companies are turning to various security measures to safeguard online assets, one of which is penetration testing. Also referred to as pen-test, penetration testing is a vital component of a robust security strategy. Its popularity is rising as it helps assess web applications’ vulnerabilities and create plans to protect them from potential attacks. In this blog, we will explore web application penetration testing more, understand its significance, and the protective value it brings to businesses.

What Is Penetration Testing? 

In simple terms, a pen test focuses on assessing the security of a web application itself, not the entire company or network. During this test, experts simulate attacks from inside and outside the application to find any weak points that could expose sensitive data.

The pen test aims to identify security weaknesses across the entire web application, including its source code, database, and back-end network. By doing so, developers can better understand the vulnerabilities and threats and prioritize them. Such activities enable them to develop effective strategies to fix and protect the web application from potential attacks. Ultimately, the pen test helps ensure the web app’s security is strong and resilient.

Importance of Website Penetration Testing

  1. Uncovers hidden vulnerabilities in web apps, addressing security gaps.
  2. Evaluates the effectiveness of current security policies for protection against cyber threats.
  3. Ensures publicly exposed components like firewalls and routers are secure.
  4. Pinpoints vulnerable entry points that attackers could exploit.
  5. Prevents data theft and unauthorized access.
  6. Overall, safeguarding sensitive data and maintaining web application security is a proactive practice.

Types of Penetration Testing for Web Applications

You can conduct web application penetration testing in two ways: internal and external. Let’s explore the differences between these two types of tests and their methodology.

Method 1: Internal Pen Testing

Internal penetration testing occurs within the organization’s network, including testing web applications hosted on the intranet. This type of testing allows the identification of vulnerabilities within the corporate firewall.

It’s essential not to underestimate the significance of internal penetration testing, as some people wrongly assume that attacks can only come from external sources. Various internal attacks can occur, such as:

  • Malicious Employee Attacks 

Disgruntled employees, contractors, or former personnel who still have access to internal security policies and passwords generally cause such attacks.

  • Social Engineering Attacks 

In these attacks, the attacker tricks people into revealing sensitive information or performing specific actions that lead to compromised security.

  • Phishing Attacks

Phishing is a form of social engineering where the attacker sends deceptive emails containing malicious links resembling authentic ones to steal information.

  • Attacks using User Privileges

Here, the attacker gains access to a user’s account, often through password theft or cracking.

The internal penetration test involves accessing the network without valid credentials, identifying possible attack routes, and ensuring the organization’s security is robust.

Method 2: External Pen Testing

External pen testing assesses the organizations plus facing assets from outside the organization. Ethical hackers, with no internal info, use the target system’s IP address to simulate real external attacks. They rely on their skills to find publicly available data about the target system, aiming to infiltrate and detect vulnerabilities. Depending on the scope, this test may evaluate the functionality and capability of the target’s firewalls, servers, and IDS & IPS (if any) to strengthen defense against external threats and secure web apps from outside attacks.

Web Application Penetration Testing Methodology

Web application penetration testing follows a four-step cycle to ensure comprehensive security assessment:

  1. Reconnaissance

In this initial phase, testers gather information about the target for testing purposes.

  1. Mapping

Once target names and IP addresses are known, the network topology is mapped to understand how different networks are connected and the security controls in place.

  1. Discovery

After mapping the target’s network, testers search for vulnerabilities that could grant unauthorized access to sensitive data.

  1. Exploitation 

In the final step, testers create exploits like SQL injections or buffer overflows to test and gain access to sensitive information within the system.

Automated vs. Manual Pen testing

There are two main ways to conduct a penetration test: automated and manual.

Automated pen testing uses specialized software tools to scan a system for vulnerabilities and perform attacks quickly. It is efficient and can cover many vulnerabilities in a short time. However, it may sometimes report false positives and miss specific vulnerabilities requiring human insight and experience.

On the other hand, manual pen testing involves a skilled security professional manually testing and exploiting vulnerabilities in the system. It requires more time and effort but can be more thorough and accurate. Manual testing can uncover vulnerabilities that automated tools might overlook, allowing the tester to think creatively and adapt to unexpected situations.

Both methods have strengths and weaknesses, but combining them can lead to a more comprehensive and effective penetration test. Many companies find that using both automated and manual approaches together gives them the best results, taking advantage of each method’s benefits.

Web applications offer convenience, cost-effectiveness, and added value to users. Yet, they often become accessible to the public, making data susceptible to those who conduct research. Even advanced web apps can have vulnerabilities in their design and configuration, which hackers can exploit. Therefore, ensuring web application security is crucial, particularly when handling sensitive information. Website penetration testing should be a top priority for businesses and organizations.
