ETSI has published TS 103 457, a new specification that standardizes an interface between a trusted secure vault and cloud environments to protect sensitive data in virtualized networks. This standard enables secure authentication for billing and allows organizations to run sensitive functions in lower-security environments while keeping critical data protected in the vault. The specification also includes a logging function to audit customer data queries, which helps detect breaches and deter malicious activity. By defining an interoperable interface, the standard ensures that organizations can switch between vault or cloud providers without losing functionality.
