Is Your Website Safe? Find Out with Security Vulnerability Testing

The security of your website is one of the most important aspects you should focus on as a business that serves customers online. With cyber threats constantly evolving, it’s important to ensure your website is secure. The neccessity for website security over the years is what has led to the many tools and methods to test for website security and also make these websites secure.

Cyber attacks can lead to significant financial loss to businesses and other problems that can run a business to the ground. In this article, we’ll explore the world of website vulnerability testing, from the types of tests that can be carried out to popular tools used in carrying out this test.

Let’s get started!

Testing for website security vulnerabilities is a process that aims to discover, assess, and reduce any potential security weakness of a web application. It attempts to expose vulnerabilities that, if exploited, may result in unauthorized access to data and websites and also disrupt website functionality. The process normally entails running different classes of tests against the web application's security.

Website security testing for vulnerabilities is important for the following reasons:

• It protects sensitive information from access and leakage, hence averting financial losses associated with theft and fraud.
• It helps in retaining the users trust that the websites are safe to use and, in turn, helps protect a website's reputation.
• It provides protection from legal liabilities by ensuring that the website complies with the desired regulatory provisions through periodic security testing.
• It increases website performance by detecting and fixing problems that may somehow undermine stability or the user experience.
• Continuous testing will get sites ready to fight off ever-new cyber threats by keeping security robust in an ever-changing environment.

In the next paragraph we’ll look at the different classes of test and the tools they offer to run security checks on websites.

SAST involves the analysis of vulnerabilities in a website's source code, nothing gets executed. Because this kind of testing is normally conducted during the development process, a developer can easily fix issues and solve them before the application goes live. Basically, SAST tools examine the code looking for known Deeplinks that indicate potentially security-related risk code, such as SQL injection or cross-site scripting.

SAST Tools

• SonarQube: An open-source platform that continuously inspects code quality and security.
• Fortify Static Code Analyzer: A commercial tool that provides comprehensive security analysis of source code.

DAST scans a running application for vulnerabilities that could be triggered while in operation. In contrast to SAST, no access to source code is required for this kind of testing. Instead, DAST simulates an attack on a running application for potential weaknesses, like insecure server settings or bugs in the authentication flow. It's especially very good at catching issues that arise from interactions between parts of the application.

DAST Tools

• OWASP ZAP: An open-source tool that helps find security vulnerabilities in web applications.
• Acunetix: A commercial web vulnerability scanner that automates security testing.

RASP Tools

• Signal Sciences: Offers RASP solutions to protect applications from real-time threats.
• Imperva RASP: Provides runtime protection against application-level attacks.

Penetration testing tools

• Metasploit: A tool for checking exploited code.
• Burp Suite: A toolset for web application security testing.

• False Positives: A false positive occurs when testing tools incorrectly identify vulnerability that doesn’t exist in the website. To fix this, a regular update to the configuration of the testing tool is needed.
• Integration Issues: Integrating security checks into your CI/CD pipeline can be a complex task. You can fix this by automating your testing process with tools that integrate smoothly with your CI/CD pipeline to reduce manual effort.
• Resource Constraint: Website vulnerability testing can be resource intensive, requiring a lot of time and compute power. A good way to handle this issue is to priotize testing efforts based on risk management and focus on critical areas of the application.
