What changed

The United States Patent and Trademark Office (USPTO) has issued patent US12585806B2, covering a novel method and system for enhancing security in serverless cloud environments. The patented technology, assigned to TATA CONSULTANCY SERVICES LIMITED, focuses on privacy-preserving workflow validations. Unlike prior art that validates entire workflows, this invention performs checks at ingress points and critical intermediate stages, thereby preventing attacks that may occur after initial validation. It also addresses the insecure storage of policy data in existing systems by implementing secure and encrypted storage mechanisms.

This patent grant signifies a new technological advancement in cloud security, particularly for serverless architectures. While patents do not impose direct regulatory obligations on entities, they can influence industry standards and product development. Companies operating in or utilizing serverless cloud environments, especially those handling sensitive data or requiring robust security protocols, should be aware of this patented technology. The innovation aims to provide enhanced data security and protection against sophisticated cyber threats, potentially impacting future security solutions and compliance considerations in cloud computing.

Abstract

State of the art approaches used to address security aspects in serverless platforms perform workflow validations on an end to end flow, however, this cannot prevent attacks targeted at intermediate function calls in the workflow. Further, the existing systems store policy data in insecure manner, which causes security issues. The disclosure herein generally relates to serverless clouds, and, more particularly, to a method and system for privacy-preserving workflow validations in serverless clouds. The system stores policy data in a secured/encrypted manner. The system also performs validations at different levels, at a first level to allow/deny access at an ingress point, and at a second level to allow/deny access at critical intermediate points. This approach thus provides safety against attacks that may have been initiated post initial validation, and offers added data security.
