Web application security is a critical concern in today's digital landscape, where vulnerabilities can lead to substantial financial and reputational damages. Effective security testing ensures that web applications function correctly and resist malicious attacks. Among various tools available, open-source vulnerability scanners are valuable for organizations aiming to maintain security without incurring high costs.

The 14 Best Open Source Web Application Vulnerability Scanners, updated for 2018, include notable tools such as OWASP ZAP and Wapiti. Both tools are popular within cybersecurity communities for their ease of use and comprehensive scanning capabilities. Evaluating these tools underscores the importance of selecting suitable security scanners based on specific organizational needs—considering factors like detection accuracy, usability, and integration capabilities.

Comparison of Two Vulnerability Scanners

OWASP ZAP (Zed Attack Proxy) is a widely adopted open-source security tool designed to find security vulnerabilities automatically in web applications. Its user-friendly interface and active community support make it accessible even for users with limited security expertise. ZAP offers automated scanners, intercepting proxies, and various attack modes, making it a versatile choice for both beginners and experts. Its notable advantages include continuous updates, active community forums, and comprehensive documentation, though it may sometimes produce false positives, requiring manual review.

Wapiti, on the other hand, is a command-line-based scanner valued for its lightweight design and scripting capabilities. It can scan multiple web pages simultaneously and identify common vulnerabilities such as SQL injections and XSS. Wapiti’s simplicity makes it suitable for automation within CI/CD pipelines and integration into larger security frameworks. Its disadvantages include a steeper learning curve compared to GUI tools and fewer visual aids, which may hinder usability for less experienced testers.

Frequency and Methodology of Security Testing

Organizations should conduct security testing regularly, ideally at least quarterly, and after any significant updates or changes to web infrastructure. Continuous integration and deployment practices necessitate integrating vulnerability scanning into development pipelines to catch vulnerabilities early. Manual testing combined with automated scans provides a thorough approach, allowing for detailed analysis and identification of complex security flaws.

Neglecting security testing can result in data breaches, loss of customer trust, legal liabilities, and financial penalties. Historical incidents, such as the Equifax breach, demonstrate the devastating effects of overlooked vulnerabilities. Therefore, establishing routine testing schedules and employing a mix of automated tools and manual assessments are vital.

External Testing Benefits

Outsourcing security assessments to external firms offers several benefits. External testers provide fresh perspectives, use diverse tools, and often identify vulnerabilities internal teams might overlook. Their experience with various attack scenarios can simulate real-world breaches more effectively. Moreover, external audits comply with industry standards and help avoid conflicts of interest.

For example, companies like Symantec and Trustwave regularly perform external security audits, which can enhance overall security posture. These external evaluations often lead to strategic improvements, increased stakeholder confidence, and compliance with regulatory requirements.

Conclusion

In conclusion, regular security testing using open-source tools like OWASP ZAP and Wapiti is essential to maintaining web application integrity. Frequent assessments, combined with external audits, create a robust defense against evolving threats. Organizations must remain proactive, integrate testing into their development lifecycle, and prioritize external evaluations to ensure comprehensive security coverage.
