With more than 100 national data privacy laws on the books as of the end of 2016 (including the landmark GDPR in Europe), any global enterprise, SaaS vendor or cloud solution provider needs to pay attention to how data residency requirements for data-at-rest can be met within their environment. Though there is a wide variation between requirements, meeting this single rule ensures that your organization remains in compliance:
For globally focused organizations, the combination of exploding volumes of customer and employee information (PII, financial data, shopping patterns, geo location information, selected preferences) with the centralized data center and cloud resources required for efficient operation can seem an insuperable problem.
For cloud providers with data centers located in jurisdictions different from those of their customers, this can represent a fundamental barrier to doing business.
The solution to the problem is to encrypt all data-at-rest, and only allow access to data-at-rest from the jurisdiction that it originates from.
With Vormetric, solving the problem is simple. Using data-at-rest encryption with access control to limit data access to only those within a specific jurisdiction will satisfy all but a few national requirements (Germany and Spain are specific exceptions).
For Enterprises: At the file system and volume level, encrypt data sets from each jurisdiction with Vormetric Transparent Encryption. Set access controls (linked to your directory services infrastructure) so that the data-at-rest can only be decrypted by those from within each country. Others will have no access to information, seeing only encrypted data blocks. For best practice, have each country keep their own encryption keys locally, so that even security management personnel from outside their jurisdiction cannot change encryption keys or access policies.
For access to information stored within databases and applications – link access to directory services infrastructure or other access management tools. You can also encrypt data on a column, field or database file level with Vormetric Application Encryption, and manage encryption keys using the Vormetric Data Security Management appliance interfaces to match jurisdictions. Enterprises can use Vormetric’s centralized, uniformly managed Data Security Manager to coordinate these operations.
Vormetric’s Data Security Platform also features the Vormetric Cloud Encryption Gateway, which extends the Platform to safeguard sensitive data in cloud storage environments, including Amazon S3, Box and Caringo. The cloud security gateway encrypts sensitive data before it is saved to the cloud. This enables security teams to establish the visibility and control they need around sensitive assets without having to add another point tool that increases system complexity.
For Cloud Providers: Offer customers the option to encrypt data-at-rest, managing their own encryption keys from within their local jurisdiction, and locking out access by others. With Vormetric Transparent Encryption, data-at-rest encryption is done by giving each customer their own local physical or virtual Vormetric Data Security Manager, combined with agents on each customer system linked to that management instance.
