This cybersecurity information sheet (CSI) provides recommendations for maturing data security and enforcing access to data at rest and in transit, ensuring that only those with authorization can access the data. It further discusses how these capabilities integrate into a comprehensive Zero Trust (ZT) framework. 

Recent events highlight that adversaries who are successful at gaining a foothold in information systems often readily gain unfettered access to all data in those systems. By applying the recommendations in the data pillar, including identifying risks to data, integrating granular data attributes into access control mechanisms, and monitoring data access and use, organizations will reduce the impact and consequences of breaches and identify suspect activity earlier in the cyber intrusion lifecycle.
