OWASP Penetration Testing Guide

Quick Summary: Security assessment plays a crucial role in protecting your data and applications from rising cyber threats. OWASP pen testing is a widely adopted method for security assessment that helps discover the most critical security risks. It helps bolster your security posture by allowing you to uncover and eliminate these risks early before an attacker exploits them. Read on to understand what the OWASP penetration test is and how it works!

In a world where cyber threats are constantly targeting businesses, security testing is not an option; it is necessary to keep your applications and data secure. But the question is – where should you start from? Consider OWASP penetration testing, which helps you discover and address the most common cyber security risks in web applications, APIs, and other assets.

It serves as a foundation for a comprehensive security assessment that helps you mitigate potential risks and reduce your attack surface. You can evaluate your applications and APIs to check for critical cyber threats listed in the OWASP top ten. The test will help you address vulnerabilities that can cause serious security risks like cross-site scripting, misconfigurations, CSRF, DDoS, etc.

Proactive testing will help you avoid costly data breaches and maintain your customer’s trust in your organization. This OWASP pentesting guide helps you understand this concept along with the method to leverage it for your organization.

What is OWASP Penetration Testing?

OWASP penetration testing is a security assessment approach that focuses on the ten most critical vulnerabilities mentioned in the OWASP top 10 list. It involves identifying, exploiting, and addressing these vulnerabilities while performing simulated real-world attacks on web applications, APIs, and mobile apps.

The objective of this testing is to discover common security vulnerabilities as early as possible before an attacker can exploit them. OWASP (Open Web Application Security Project) is a non-profit organization that publishes the lists of top ten security threats for web apps, APIs, mobile apps, etc.

The organization also provides security best practices and guidelines to remediate vulnerabilities. OWASP pen testing considers these vulnerabilities, practices, and guidelines to mitigate cyber risks. So, a pentester will plan test cases considering the OWASP top ten risks to identify threats.

Understanding the Critical Role of OWASP Penetration Testing in Security

OWASP pentest is a strategic approach to security audit as it focuses on a specific type of vulnerability. OWASP top ten lists the most critical risks that have been collated after a consensus among developers and security teams worldwide.

So, it offers a reliable benchmark for identifying and addressing security vulnerabilities. Pentesters can simulate an attacker’s behavior to test applications for these vulnerabilities and reduce the attack surface of your organization.

OWASP penetration testing offers many significant advantages to organizations as follows.

  • You can discover vulnerabilities early in your development lifecycle, resulting in improved application security.

  • OWASP testing enables you to address the most critical security risks that significantly reduce the chances of data breaches and cyberattacks.

  • OWASP pentesting methodology is also conducive to complying with varied standards like GDPR, PCI DSS, OWASP, etc.

  • It helps your organization identify and address security vulnerabilities before attackers exploit them.

  • It also helps strengthen your data security measures that ensure customer trust and maintain your reputation.

Common Pitfalls of OWASP Penetration Testing

OWASP top ten serves as a foundation for penetration testing, allowing your organization to uncover severe security risks. However, this approach isn’t always good and has a few limitations. These OWASP pen testing pitfalls can arise during tests that can affect overall testing results. Let’s see these pitfalls below.

  • A limited scope of vulnerabilities can result in missed vulnerabilities, as critical areas might be overlooked.

  • Every organization implements different types of business logic and neglecting this aspect can leave many kinds of vulnerabilities untested.

  • It neglects other attack vectors that might pose security risks, like vulnerabilities that may arise in your internal IT infrastructure.

Breaking Down the OWASP Pentest Methodology

Conducting pentests requires a systematic framework to ensure optimal assessment and to discover risks accurately. Penetration Testing Execution Standard (PTES) is one of the top penetration testing methodologies to conduct OWASP pen testing. The following is a breakdown of the different phases of this methodology.

Pre-engagement Interactions

It involves defining the scope and other aspects that ensure a successful pen test. You can think of it as setting a roadmap to conduct pen tests with the defined rules, constraints, and expectations. It begins by defining the testing scope and the targets. The next step is gaining the required permissions and setting up communication channels for reporting.

Intelligence Gathering

The next phase is also known as reconnaissance, and it aims to gather as much information as possible about the target. This information helps plan an attack. For example, intelligence gathering for a web application includes knowing about the server, API endpoints, structure, crawled data, etc.

Threat Modeling

It helps discover potential security vulnerabilities in an application and its environment. Threat modeling involves creating a representation of an application with its components to understand the possible weaknesses. It helps pinpoint risks and assesses the likelihood of occurrence of each risk.

Vulnerability Analysis

The next phase is actively scanning the target for vulnerabilities and identifying common security flaws as mentioned in the OWASP top ten list. It involves automated and manual testing methods to uncover vulnerabilities. Automated vulnerability scanning offers a quick outcome and helps discover known vulnerabilities.

Exploitation

Once vulnerability analysis identifies the common risks in the target web application, the next phase involves performing the exploitation of these vulnerabilities. It helps you understand the potential impact of these vulnerabilities. Plus, it shows the real-world impact of these risks.

Post Exploitation

Post-exploitation is performed to identify how critical an exploited target is depending on the sensitivity of the data it stores. Plus, it also assesses the possibility of maintaining control of a compromised target and later movement.

Reporting

The final phase of the PTES pentesting method is reporting, which contains two sections – executive summary and technical details. It involves a prioritized view of different vulnerabilities depending on the severity and potential impact. Your security team can draw up a remediation plan based on this report.

OWASP Top 10 Risks Covered in Pen Testing

The list of top ten web app risks is curated by OWASP to help developers and security teams mitigate critical risks and improve application security. This list also serves as a foundation for web application security testing to identify vulnerabilities like SQL injection, broken authentication, misconfiguration, etc. The following are the different risks covered in OWASP pentest checklist.
