Hybrid security model for remote browser isolation (rbi) to protect against web-based threats

Abstract

The present invention relates to a hybrid security model for Remote Browser Isolation (RBI) environments to protect against web-based threats while ensuring secure and efficient application execution. The invention integrates sandboxing and application preapproval to enhance security and performance. Sandboxing isolates critical processes, preventing interference and containing malicious activities. A process isolation algorithm assigns dedicated resources, ensuring independent task execution. A resource limitation algorithm restricts CPU, memory, and disk space usage, optimizing resource allocation. Network access control prioritizes network resources for critical tasks, while file system virtualization limits access to specific files. Behavior monitoring algorithms detect and contain unauthorized activities, raising alerts in real time. Application preapproval improves efficiency by allowing trusted applications to bypass the isolation layer. By combining proactive threat detection, dynamic resource management, and granular access control, the invention delivers robust protection, ensuring secure and reliable operation of web applications across RBI environments.
