Combat Proxy Testing with Zero Trust Biometrics in Online Certifications
December 16, 2024 | 5 minute read
The growth of online certifications and testing globally has brought unparalleled convenience, accessibility and cost savings—but it also comes with a new set of challenges. While cheating is nothing new, proxy testing – where individuals fraudulently complete exams on behalf of others – threatens to undermine exam integrity and erode trust in the institutions providing them.
While exact statistics around the prevalence of proxy testing are hard to come by, the many recent public scandals involving high-profile exams have unearthed a world of cheating that’s recognized by some groups as arguably common.
In response, many organizations are turning to advanced technologies like biometrics and AI-driven proctoring to combat these threats. However, securing online testing environments also requires a foundational shift in how institutions approach security. The concept of Zero Trust—a “never trust, always verify” framework—is gaining traction as a comprehensive strategy for maintaining the credibility of online certifications.
What is Proxy Testing?
Proxy testing, aka when one hires another person, known as a “proxy,” to take an exam on their behalf, represents a significant risk to the entire certification ecosystem. Fraudulent test-takers not only devalue certifications but also diminish employer confidence in hiring candidates based on these credentials.
In industries where certifications validate critical skills—such as healthcare, IT, or public safety—the consequences of compromised trust can extend well beyond reputational damage.
Where Does Zero Trust Come into Online Certifications?
The traditional perimeter-based approach to security assumes that users within the system can be trusted. Unfortunately, this assumption is no longer viable in the face of sophisticated fraud tactics like proxy testing. Institutions must recognize that trust is not an inherent right—it must be earned, verified, and continuously reinforced through rigorous controls.
Enter Zero Trust, a framework for secure and trusted testing. The Zero Trust model fundamentally changes how online testing institutions approach security. It operates on the principle of continuous verification, ensuring that every user, device, and action is authenticated and authorized before access is granted. This framework is particularly effective in mitigating the risks associated with proxy testing.
The Key Principles of Zero Trust for Online Testing and Exams
- Verify Continuously: Identity verification doesn’t stop at login. Regular biometric or behavioral checks ensure the same individual completes the exam throughout the entire testing process.
- Least Privilege Access: Limit access to testing platforms, question banks, and other sensitive resources to only those who need it—and only for as long as they need it.
- Assume Breach: Operate under the assumption that breaches can and will occur. Implement systems to monitor, detect, and respond to suspicious activity in real-time.
Biometrics as the First Line of Defense in a Zero Trust Approach
Zero Trust is not just a concept; it requires robust tools to implement effectively. Biometrics, AI-driven proctoring, and behavioral analytics are critical components that align seamlessly with this framework.
Biometric technology uses unique physical or behavioral characteristics—such as fingerprints, facial features, voice patterns, or typing dynamics—to verify a person’s identity. Unlike traditional methods like passwords, biometrics are difficult to replicate, making them a highly secure and reliable way to authenticate users. This technology is especially useful in combating fraud, enhancing security, and maintaining trust in digital environments like online certifications and testing.
Within a Zero Trust framework, biometric tools can:
- Enable Continuous Verification: Repeatedly confirm the test-taker’s identity throughout the session.
- Prevent Unauthorized Access: Ensure only authorized individuals can access the testing platform and exam materials.
- Act as a Fraud Deterrent: The presence of biometric checks discourages fraudulent behavior from the start, creating a secure environment for honest test-takers.
Transparency and Ethical Considerations in Zero Trust
Adopting a Zero Trust approach must be accompanied by a commitment to transparency and ethical practices. Institutions should:
- Clearly Communicate Policies: Test-takers must understand why and how their data is being used, particularly when biometric or AI tools are involved.
- Ensure Privacy Protections: Adhere to stringent data protection laws and industry standards to safeguard sensitive information.
- Foster Inclusivity: Provide alternative verification methods to accommodate users who cannot access or use certain technologies.
Building Resilient Exam Security Together
No single institution can address these challenges alone. As proxy testing becomes increasingly sophisticated, online certification providers must evolve to stay ahead of the curve. Implementing Zero Trust principles, combined with advanced technologies like biometrics and AI, offers a path forward to secure the credibility of online testing.
This isn’t just about technology; it’s about a mindset shift. By embracing a Zero Trust framework, institutions can:
- Strengthen the security of their systems.
- Enhance trust with test-takers, employers, and other stakeholders.
- Preserve the value of certifications in a competitive, fast-changing world.
By sharing best practices, adopting interoperable technologies, and committing to a Zero Trust approach, the industry as a whole can maintain its integrity and relevance. Together, we can ensure that online certifications remain a trusted measure of achievement, skill, and knowledge.
Adopting Zero Trust isn’t just about combating today’s threats—it’s about future-proofing the online testing industry for years to come. With innovation, transparency, and collaboration, we can build a system where security and trust are uncompromising pillars of success.
