In a significant move to bolster data security in artificial intelligence (AI) systems, the National Security Agency (NSA) and the Cybersecurity and Infrastructure Security Agency (CISA), in collaboration with international partners, released comprehensive guidance on May 22. This guidance is crucial for organizations leveraging AI and machine learning technologies, as it outlines potential risks associated with data integrity issues during various stages of AI development and usage. It also provides best practices to secure data within AI-based systems.
The guidance specifically targets three major areas of concern regarding data security in AI systems:
1. Data Supply Chain : Ensuring the integrity and reliability of data sources is paramount. The guidance emphasizes the need for organizations to source data from reputable and secure channels to prevent contamination or corruption.
2. Maliciously Modified or ‘Poisoned’ Data : AI systems are highly susceptible to data poisoning, where malicious actors deliberately input corrupt data to manipulate outcomes. The guidance stresses the importance of implementing robust security measures to detect and mitigate such attempts.
3. Data Drift : Over time, data sets may evolve, leading to discrepancies between the training data and real-world data. This phenomenon, known as data drift, can significantly impact the performance and accuracy of AI models. The guidance advises continuous monitoring and updating of data sets to address this issue.
John Riggi, the national advisor for cybersecurity and risk at the American Hospital Association (AHA), highlighted the importance of this guidance. “This crucial reference guide, compiled by the world’s leading government AI experts, is a must-read for healthcare leaders involved in the governance, development, or deployment of AI systems in their organizations,” Riggi stated. He further elaborated on the methodologies discussed in the guide, which are essential for maintaining data security and integrity throughout the AI system lifecycle.
Key Methodologies Include :
– Sourcing Reliable Data Sets : Starting with trustworthy data sources is fundamental to ensuring the overall security of AI systems.
– Immutability and Encryption Tools : Employing these tools helps protect data from unauthorized alterations and ensures that any changes to AI systems and data are securely documented.
– Digital Signatures : Utilizing digital signatures can validate and authenticate data transactions, providing an additional layer of security.
The guidance also calls for organizations to adopt a proactive approach to cybersecurity by staying informed about emerging threats and continuously updating their security practices. By doing so, organizations can better defend against cyberattacks and ensure the resilience of their AI systems.
