Web application penetration testing is a security review method designed to uncover vulnerabilities in web-based applications. By simulating real-world cyberattacks or delving deep into the software code, pen-testers explore the application’s security controls, data protection mechanisms, and potential entry points to discover security gaps and offer actionable remediation advice.
3 Key Penetration Testing Strategies
Black box penetration testing. Pentesters approach the web application as outsiders and attempt to exploit vulnerabilities without any prior knowledge of the target. They use manual and automated testing techniques and employ social engineering to simulate various attack scenarios, identify potential entry points, and evaluate the application’s defenses against attacks from outside.

Common Web Application Security Risks
- SQL injections occur when attackers paste code in your website’s input fields (e.g., log-in forms) to execute malicious SQL queries. This can lead to sensitive data breaches or data manipulation or even give the attackers complete control over the app. Proper input validation and the use of parameterized queries can help prevent SQL injection.
- Cross-site scripting (XSS) allows hackers to inject scripts into web pages viewed by other users, enabling the theft of users’ cookies, personal information, or redirection to malicious websites. Proper input validation and output encoding can help mitigate XSS attacks.
- Cross-site request forgery (CSRF) occurs when attackers use another website’s cookies saved in a user’s browser to trick it into performing actions on that website without the user’s knowledge. For example, a malicious site can change your social media password using the cookie as proof of your request. Preventing CSRF involves using anti-CSRF tokens that ensure that only the real user can initiate web actions.
- Broken access controls allow unauthorized users to gain access to restricted resources or functionality. This vulnerability occurs when proper access controls, such as user roles and tiered privileges, are not effectively enforced.
- Similarly, broken authentication allows attackers to bypass authentication mechanisms and gain unauthorized access to web app accounts. This can result from weak password policies, insecure session management, or predictable authentication tokens.
- Security misconfigurations occur when an application or its infrastructure is not broken per se but is not set up securely. For example, you didn’t update an obsolete protocol in time or didn’t review default access permissions, making a confidential directory available to anyone. Regular security audits and proper configuration management are vital for preventing this vulnerability.
