Authentication Controls for Access to High-Risk AI Models
Authentication Controls for Access to High-Risk AI Models
Powering the Future with AI
Key Takeaways
High-risk AI systems can cause real-world harm, making their security a public safety issue, not just an IT concern.
Protecting these systems requires a Zero Trust approach, since single-factor authentication is no longer sufficient.
Multi-factor authentication reduces breach risk by requiring multiple forms of verification instead of relying on passwords alone.
Risk-based and adaptive authentication strengthen security further by adjusting access controls in real time based on user behavior and context.
As artificial intelligence becomes more powerful and more pervasive, a new and more consequential category of AI is emerging: high-risk AI. These are not the friendly chatbots and recommendation engines that we have grown accustomed to. These are AI systems that have the potential to cause significant harm to individuals, to organizations, and to society as a whole. As defined by the European Union’s landmark AI Act, high-risk AI systems are those that are used in a number of critical areas, from transportation and energy to education and law enforcement. For enterprises in the Middle East and North Africa (MENA) region, which are investing heavily in a wide range of high-risk AI applications, securing these powerful new systems is a top priority.
At the heart of this security challenge is a simple but critical question: how do you control who has access to a high-risk AI model? A single password is not enough. A compromised high-risk AI model could be used to steal sensitive data, to disrupt critical infrastructure, or even to cause physical harm. The potential for misuse of these systems is immense.
The Problem: The Single Point of Failure
For decades, the password has been the primary means of authentication. But in today’s world of sophisticated cyberattacks, the password has become a single point of failure. A stolen password can give an attacker the keys to the kingdom, allowing them to access sensitive data, to disrupt operations, and to cause untold damage. For high-risk AI models, the consequences of a stolen password can be catastrophic.
The Solution: A Multi-Layered, Defense-in-Depth Approach
Protecting high-risk AI models requires a multi-layered, defense-in-depth approach to authentication. A risk-based approach to AI controls is essential. This involves using a combination of different authentication factors to create a more robust and more resilient security posture.
1. Multi-Factor Authentication (MFA): The Foundational Layer
Multi-factor authentication (MFA) is a security best practice that requires users to provide two or more verification factors to access a resource. These factors can be something you know (like a password), something you have (like a security token or a mobile phone), or something you are (like a fingerprint or a facial scan). By requiring multiple factors, MFA can significantly reduce the risk of a security breach, even if an attacker has stolen a user’s password.
2. Risk-Based Authentication (RBA): A More Intelligent Approach
Risk-based authentication (RBA) is a more advanced form of authentication that dynamically adjusts the authentication requirements based on the real-time risk of a particular access request. RBA takes into account a wide range of different factors, including:
- User Location: Is the user trying to access the system from a familiar location or from a new and unusual one?
- Device: Is the user using a trusted device or a new and untrusted one?
- Time of Day: Is the user trying to access the system at a normal time or at an unusual time?
- User Behavior: Is the user behaving in a normal way or in a suspicious way?
Based on the risk score that is assigned to a particular access request, the system can then decide whether to allow the access, to deny it, or to require an additional authentication factor.
3. Adaptive Authentication: The Future of Secure Access
Adaptive authentication is a more sophisticated form of RBA that uses AI and machine learning to continuously assess the risk of a particular user session. Adaptive authentication can analyze a wide range of different factors, including the user’s location, their device, their behavior, and the time of day, to determine the appropriate level of authentication. This allows for a more seamless and user-friendly experience, as users are only prompted for additional authentication when it is absolutely necessary. It also provides a higher level of security, as it can detect and respond to threats in real time.
A Roadmap for Securing Your High-Risk AI Models
Securing your high-risk AI models requires a thoughtful and strategic approach. Here is a high-level roadmap for getting started:
- Identify Your High-Risk AI Models: The first step is to identify all of the AI models in your organization that could be considered high-risk. This will involve conducting a thorough risk assessment of all of your AI systems.
- Implement Multi-Factor Authentication (MFA): The next step is to implement MFA for all users who have access to your high-risk AI models. This is a foundational security control that should be in place for all of your critical systems.
- Consider Risk-Based and Adaptive Authentication: For your most sensitive AI models, you should consider implementing a more advanced authentication solution, such as RBA or adaptive authentication. This will provide an additional layer of security and will help to protect against the most sophisticated threats.
- Regularly Review and Update Your Authentication Policies: Your authentication policies should be reviewed on a regular basis to ensure that they are still appropriate. As the threat landscape evolves, you may need to adjust your policies to provide a higher level of security.
Building better AI systems takes the right approach
Conclusion: A Secure Foundation for the Future of AI
The rise of high-risk AI is creating a new and formidable security challenge. But it is also creating a new and exciting opportunity. By embracing a multi-layered, defense-in-depth approach to authentication, MENA enterprises can build a secure and resilient foundation for their AI innovation. They can protect their most valuable assets, they can ensure the safety and security of their citizens, and they can lead the way in the new and exciting era of secure and responsible AI.
