Browser Policy Enforcement Modules for Secure Web Application Execution

The browser is divided into distinct functional modules: a web browser core unit for basic interpretation, a network policy enforcement unit for communication control, a storage policy enforcement unit for data access control, and an ancillary policy enforcement unit for authentication. Each module operates independently to enforce specific security policies, allowing comprehensive security enforcement without requiring complete system redesign.

Policy enforcement units act as intermediary layers between the web application logic and the underlying system resources (network facility, storage facility, authentication mechanisms). These intermediaries intercept and control access requests, enforcing security policies without requiring changes to the web applications themselves, thus maintaining reliability while managing complexity through clear separation of concerns.

Security policies are acquired and configured in advance before web applications execute on mobile devices. The policy enforcement units are pre-loaded with network policies, storage policies, and authentication requirements, enabling automatic enforcement during application operation without requiring real-time security decisions, thus ensuring reliable secure operation while maintaining ease of mobile access.

The browser automatically enforces security policies without requiring manual intervention from users or administrators during operation. The policy enforcement units autonomously control network access, storage operations, and authentication processes based on pre-configured policies, allowing mobile users to access web applications conveniently while security is automatically maintained through self-enforcing mechanisms.
