Policy-Server Label Access for Secure Data Classification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Organizations face challenges in managing and controlling data classification labels securely while maintaining extensibility across different platforms, as the number and type of labels vary and accessibility differs among users and clients.
Innovation Solution
A framework that integrates data classification labels using a policy server, enabling seamless integration and access control through authentication routines, allowing users to retrieve and apply labels dynamically based on their permissions, ensuring secure and user-friendly data classification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data classification labels are made accessible to multiple users and applications, then extensibility and usability are improved, but security and access control become more complex
Solution Approach 1:
The patent introduces a policy server as an intermediary component that mediates between applications and data classification labels. The policy server receives authentication information from applications, performs rights checks, and returns access tokens that enable controlled access to labels. This intermediary architecture allows multiple applications to access classification labels without requiring complex point-to-point access control logic in each application, thus improving extensibility while managing access control complexity centrally.
2Reliability
If authentication and rights checks are performed for every label access, then security is improved, but processing time and operational complexity increase
Solution Approach 1:
The patent implements preliminary authentication by requiring applications to provide authentication information and receive access tokens before accessing data classification labels. The policy server performs rights checks in advance and issues tokens that encapsulate the authentication results. This preliminary action ensures security requirements are met before label access occurs, while the token mechanism avoids repeated authentication overhead for subsequent label operations within the same session.
3Reliability
If data classification labels are centralized in a policy server, then security and consistency are improved, but system complexity and integration requirements increase
Solution Approach 1:
The patent designs the policy server with universal functionality that serves multiple purposes: storing data classification labels, performing authentication verification, issuing access tokens, and managing rights checks. This multi-functional design consolidates what could be separate components into a single unified system, improving consistency and security while actually reducing overall system integration complexity compared to distributed label management approaches.
Data Source
AI summary
Systems and processes for managing and applying data classification labels are provided. In a method for managing data classification labels, a request may be received from a client application to fetch data classification labels from a policy server. Authentication information may be retrieved and passed to the policy server, and an access token may be received from the policy server based on a rights check performed using the authentication information. The access token may be provided to an interface for the policy server for use in generating a request for a list of data classification labels accessible via the access token, and the list of data classification labels may be received. Output data usable by the client application to generate a presentation of the list of data classification labels for selection by a user of the client application to classify data managed by the client application may be generated.
