EXECUTIVE SUMMARY:
Artificial intelligence and large language models are transforming how organizations operate. They’re also generating vast quantities of data – including synthetic text, code, conversational data and even multi-media content. This introduces increased potential for organizations to encounter hacking, data breaches and data theft.
This article outlines eight essential steps that cyber security stakeholders can take to strengthen AI data security in an age where AI usage is rapidly accelerating and the societal consensus on AI regulation remains elusive.
AI data security: 8 essential steps
1. Risk assessment. The foundation of any effective security strategy is, of course, a thorough risk assessment. CISOs should conduct a comprehensive evaluation of their organization’s AI systems, identifying potential vulnerabilities, threats, and their potential impact.
This assessment should encompass the entire AI lifecycle, from data acquisition and model development to deployment and monitoring. By understanding the specific risks associated with AI initiatives, cyber security teams can prioritize and implement targeted security and mitigation strategies.
2. Robust governance framework. Effective AI data security requires a strong governance structure. CISOs need to develop a comprehensive framework that outlines data ownership, access controls, usage policies, and retention guidelines. This framework should align with relevant regulations, while incorporating principles of data minimization and privacy-by-design. Clear governance not only minimizes the risk of data breaches, but also ensures compliance with legal and ethical codes.
3. Secure development and deployment practices. As AI systems and security features are developed, cyber security teams need to ensure secure coding practices, vulnerability testing and threat modeling (where possible). In addition, security controls need to be put in-place, as to protect AI models and infrastructure from unauthorized access or data loss. Prioritizing cyber security from the outset will enable organizations to reduce the probability that vulnerabilities will be introduced into production systems.
4. Protect training data. Cyber security professionals need to implement stringent security measures to protect the integrity and confidentiality of training data. This includes data anonymization, encryption and access controls, regular integrity checks to detect unauthorized modifications, and monitoring of data for adversarial inputs.
5. Enhanced network security. AI systems often require significant computational resources across distributed environments. CISOs must ensure that the network infrastructure supporting AI operations is highly secure. Key measures include implementing network segmentation to isolate AI systems, utilizing next-generation firewalls and intrusion detection/prevention systems, and ensuring regular patching and updates of all systems in the AI infrastructure.
6. Advanced authentication and access controls. Given the sensitive nature of AI systems and data, robust authentication and access control mechanisms are essential. Cyber security teams should implement multi-factor authentication, role-based access controls, just-in-time provisioning for sensitive AI operations, and privileged access management for AI administrators and developers. These measures help ensure that only authorized personnel can access AI systems and data, reducing the risk of insider threats and unauthorized data exposure.
7. AI-specific incident response and recovery plans. While prevention is crucial, organizations must also prepare for potential AI-related security incidents. Cyber security professionals should develop and regularly test incident response and recovery plans tailored to AI systems. These plans should address forensic analysis of compromised AI models or data, communication protocols for stakeholders and regulatory bodies, and business continuity measures for AI-dependent operations.
8. Continuous monitoring and adaptation. AI data security is an ongoing commitment that requires constant vigilance. Implementing robust monitoring systems and processes is essential to ensure the continued security and integrity of AI operations. This includes real-time monitoring of AI system behavior and performance, anomaly detection to identify potential security threats or breaches, continuous evaluation of AI model performance and potential drift, and monitoring of emerging threats in the AI landscape.
