How do you integrate web application scanning into your development and testing processes?

由人工智能和领英社区提供技术支持

Web application scanning is a vital part of vulnerability scanning, as it helps you identify and fix security flaws in your web applications before they are exploited by attackers. However, web application scanning can also be challenging, as it requires coordination, collaboration, and automation across your development and testing processes. In this article, you will learn how to integrate web application scanning into your development and testing processes, and what benefits it can bring to your security and quality.

1 Choose a web application scanner

The first step to integrate web application scanning into your development and testing processes is to choose a web application scanner that suits your needs and goals. A web application scanner is a tool that simulates attacks on your web applications and reports the vulnerabilities it finds. There are different types of web application scanners, such as static, dynamic, or interactive, and they have different features, strengths, and limitations. You should consider factors such as the accuracy, speed, scalability, integration, and cost of the web application scanner, as well as the compatibility with your web application technology, architecture, and functionality.

In my experience, I have found that each type of application security testing has its unique strengths and potential drawbacks. For example, Static application security testing (SAST) is good at detecting vulnerabilities early in the development cycle but can sometimes generate false positives. On the other hand, Dynamic Application Security Testing (DAST) is excellent at identifying runtime vulnerabilities, although it might overlook some issues that SAST would pick up. Interactive application security testing (IAST) effectively marries the best features of both SAST and DAST. It offers real-time vulnerability detection and tends to have fewer false positives. However, it might need more resources for effective implementation.

2 Define your scanning scope and frequency

The next step is to define your scanning scope and frequency, which means deciding what web applications, components, and features you want to scan, and how often you want to scan them. Your scanning scope and frequency should be aligned with your risk appetite, compliance requirements, and development cycle. You should scan your web applications regularly and comprehensively, but also prioritize the most critical and sensitive ones. You should also scan your web applications at different stages of your development and testing processes, such as during code review, integration testing, or pre-deployment.

3 Automate your scanning workflow

The third step is to automate your scanning workflow, which means using tools and scripts to trigger, run, and report your web application scans without manual intervention. Automating your scanning workflow can save you time, resources, and errors, and enable you to scan your web applications more frequently and consistently. You can automate your scanning workflow by using APIs, command-line interfaces, or plugins to integrate your web application scanner with your development and testing tools, such as your code repository, build server, or test suite.

4 Analyze and validate your scanning results

The fourth step is to analyze and validate your scanning results, which means reviewing and verifying the vulnerabilities reported by your web application scanner. Analyzing and validating your scanning results can help you avoid false positives, false negatives, and irrelevant findings, and focus on the real and relevant vulnerabilities. You can analyze and validate your scanning results by using dashboards, reports, or alerts to visualize and prioritize your vulnerabilities, and by using manual testing, code review, or penetration testing to confirm and exploit your vulnerabilities.

5 Remediate and verify your vulnerabilities

The fifth step is to remediate and verify your vulnerabilities, which means fixing and testing the vulnerabilities reported by your web application scanner. Remediation and verification are essential to ensure that your web application scanning efforts are effective and beneficial, and that your web applications are secure and functional. You can remediate and verify your vulnerabilities by using tickets, patches, or updates to assign and apply fixes to your vulnerabilities, and by using re-scanning, regression testing, or monitoring to check and confirm that your fixes are working and not introducing new issues.

6 Improve and optimize your scanning process

The sixth step is to improve and optimize your scanning process, which means evaluating and enhancing your web application scanning performance, quality, and value. Improving and optimizing your scanning process can help you achieve continuous security improvement and maturity, and align your web application scanning with your business objectives and customer expectations. You can improve and optimize your scanning process by using metrics, feedback, or audits to measure and benchmark your scanning results, and by using best practices, standards, or frameworks to guide and govern your scanning activities.
