Secure Membranes for Cross-Namespace Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack a secure method to establish trust relationships and security models between components running within the same web application, as existing operating system and virtualization security measures are not applicable to the component model, leading to vulnerabilities such as malicious code execution and data theft.
Innovation Solution
The implementation of 'secure membranes' using HTML5 inline frames (iframes) or other sandboxing technologies to create isolated execution environments for components, with a handler relaying operations and sanitizing strings to prevent cross-namespace script execution and data breaches, along with cross-namespace communication mechanisms through manifest files for trusted interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If components are isolated using secure membranes, then security and integrity are improved, but communication between components becomes restricted
Solution Approach 1:
The patent introduces a handler as an intermediary mechanism that mediates communication between isolated namespaces. The handler receives messages from one namespace, validates them against security policies, and relays them to the target namespace if permitted. This resolves the contradiction by enabling controlled communication while maintaining isolation boundaries.
Solution Approach 2:
The patent implements namespace-specific security policies that define local communication qualities. Each namespace can have customized access control rules that determine which operations are permitted across namespace boundaries. This allows selective communication based on local security requirements while maintaining overall isolation.
2Adaptability or versatility
If cross-namespace communication is enabled, then component interoperability is improved, but security vulnerabilities increase
Solution Approach 1:
The patent implements a feedback mechanism where the handler continuously monitors and validates communication attempts between namespaces. Security policies are evaluated in response to each communication request, and access decisions are dynamically adjusted based on the current security state. This feedback loop enables safe interoperability by preventing malicious operations.
Solution Approach 2:
The patent applies preliminary security checks before allowing cross-namespace operations. The handler pre-validates messages, operations, and access requests against defined security policies, blocking potentially harmful actions before they can execute. This preventive approach enables controlled interoperability while neutralizing security threats in advance.
3Reliability
If strict isolation between namespaces is implemented, then data protection is improved, but operational flexibility deteriorates
Solution Approach 1:
The patent implements dynamic access control that adapts isolation strictness based on operational context. The handler can adjust the level of monitoring and validation applied to different communication requests, allowing more flexible operations for trusted components while maintaining strict protection for sensitive data. This dynamic behavior resolves the contradiction between protection and flexibility.
