How to choose the right vulnerability scanner for your security needs

Organizations find safeguarding their infrastructure and applications complex as the digital landscape becomes increasingly complicated. Unaddressed vulnerabilities can lead to devastating consequences, including data breaches, operational disruptions, and considerable financial as well as reputation damage. A robust vulnerability scanning program is essential to mitigate these risks and protect your organization’s critical assets.

However, with numerous vulnerability scanning tools, choosing the right one can take time and effort. In this article, I will outline the key factors to consider when selecting a vulnerability scanner that best meets your organization’s requirements.

What are types of vulnerability scanning

Before we dive into further details, it’s essential to understand the three approaches to application testing: DAST, SAST, and IAST. These are vital to a strong application security strategy, and it’s crucial to grasp their strengths and weaknesses to select the best security strategy.

• Static Application Security Testing (SAST): SAST is a game-changer for application security. By analyzing the code directly, they identify potential vulnerabilities at an early stage of development. This proactive approach saves time, prevents expensive security issues, and enhances the overall quality of the code. It’s like having a security watchdog at every stage of the development process.
• Dynamic Application Security Testing (DAST): DAST is an essential part of application security, testing the application during runtime to identify vulnerabilities that may only appear in specific conditions or when interacting with external systems. It helps assess exposure to threats like SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF), which SAST could overlook.
• Interactive Application Security Testing (IAST): A hybrid approach that combines the strengths of SAST and DAST, IAST provides real-time feedback on vulnerabilities as they are discovered, allowing for immediate remediation and reducing the risk of exploitation. It is commonly used to identify vulnerabilities in complex applications with dynamic components or third-party integrations.

How to select the right vulnerability scanning tool

When choosing a suitable vulnerability scanner for your organization, it’s essential to consider several key factors. Here are my top picks.

• Vulnerability database: You need a database that’s comprehensive and up-to-date. It must cover the latest threats, not just the old ones. The database should also give detailed information on each vulnerability, such as how it could be exploited and its impact. This will help with threat prioritization.
• Accuracy and false positive rate: The scanner must identify real vulnerabilities accurately without producing too many false positives. High accuracy saves time and resources. A low false positive rate minimizes disruptions to the development process, keeping the team morale high.
• Integration capabilities: The scanner should seamlessly integrate with your development and testing environments, such as IDEs, CI/CD pipelines, and issue-tracking systems. This ensures a smooth workflow, minimizes disruptions, prevents errors from manual data transfers, and enables automatic scans upon code changes.
