In the digital economy of today, this balancing act has now shifted to controlling the flow and storage of data across borders. There is a discernible trend as more and more data residency (membership required), data sovereignty and data localization requirements are proposed, enacted and enforced across the globe.
Understanding Data Residency, Sovereignty And Localization
Before delving into the implications of these requirements on data, it is worthwhile to understand the differences and similarities between these three distinct requirements.
• Data ResidencyData residency refers to the physical or geographic location...: Data residency requirements dictate the physical location where data is stored and processed. Data residency is often an internal policy requirement or contractual commitment provided to customers independently of any other regulatory requirements or the source of the data.
Companies may decide to base all their operations and data in certain geolocations for a multitude of reasons, but most commonly it is to take advantage of certain tax benefits or other commercial incentives.
• Data SovereigntyThe term “data sovereignty” refers to the concept that d...: Data sovereignty requirements encompass the legal and regulatory mandates used to exert control by a country or region over data within their borders. Increasingly, these mandates empower individuals to exert more control over their own data. Companies are required to comply with these regulations based on the location of the data.
• Data LocalizationData localization refers to the requirement that personal da...: Data localization requirements are typically regulatory mandates that enforce the storage and processing of data within the country or region it was created. Companies are required to adhere to this requirement for all data when operating in certain countries or regions.
In summary, data residency outlines the intended geographical storage and processing of data, data sovereignty is about the rights and control over data based on the jurisdiction of the data storage and processing, and data localization mandates data to remain within a specific location and jurisdiction.
What This Means For CISOs
Complying with the need to control data as a result of these emerging requirements is increasingly landing at the feet of the CISOCISO is an acronym for Chief Information Security Officer, a..., who is already tasked with securing and controlling the flow of data across the organization.
To effectively navigate the challenges imposed by data residency, data sovereignty and data localization, CISOs are now expected to know what data is within a data storeA data store is a repository or storage system used for stor..., where it is and where it is going, and be able to translate data protectionData protection refers to the set of laws, regulations, and ... laws, regulations and policies into enforceable security controls.
At a minimum, CISOs must take a multifaceted approach to data security. This starts with classifying and mapping the organization’s data, identifying where data is stored and flowing, and identifying the sensitivity, geolocation, legal requirements and other business needs associated with it. This exercise helps identify the data that requires specific data residency, sovereignty or localization measures and third parties that are involved in handling the organization’s data.
Based on the data inventoryWhat is a Data Inventory? A data inventory, also known as a ..., CISOs should task their legal and compliance teams with providing them with a comprehensive assessment of the data protection laws, regulations, governmental policies and contractual commitments to customers in the countries where data is stored or processed. They should focus on specific requirements and restrictions imposed by these jurisdictions, including any data transfer limitations or mandatory data localization rules.
By understanding the implications, CISOs can help their organizations make better-informed decisions regarding data storage and processing, ensuring compliance with regulations and safeguarding sensitive informationSensitive information is a broad term that encompasses any d....

Ensure these agreements align with data residency and data sovereignty requirements, outlining responsibilities, security measures and limitations on data access and transfer.
Most importantly, the security and protection of the data in scope should be assessed and remediated to reduce the risk of unauthorized access, destruction and alteration of data, in addition to the identified compliance issues.
These steps sound simple and achievable, but without the proper visibility and tooling to provide the fine-grained visibility needed, multinational organizations may struggle to prove their ability to meet the increasing number of data residency, sovereignty and localization requirements they encounter.
It’s not surprising, then, that CISOs are increasingly turning to data-centric tools, such as data security posture managementData Security Posture Management (DSPM) is an emerging cyber..., to power their understanding, monitor access and observe changes to the data within their environments. Without evidence-based data to demonstrate their fine-grained control of data, they know that it’s difficult to keep up with regulations.
