Secure Web Browser Isolation for BYOD Enterprise Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increased vulnerability of communications networks and digital resources due to the proliferation of personal devices (BYOD) and cloud-based services compounds the difficulty in providing cyber protection against cyberattacks, especially for enterprises with remote workers.
Innovation Solution
A cyber secure communications system (CyberSafe) with a cloud-based data and processing security hub and a secure web browser (SWB) in an isolated secure environment (CISE) that monitors and controls data ingress and egress, enforces security policies, and provides enhanced visibility and protection against cyber threats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If personal devices (BYOD) and cloud-based services are proliferated to enable remote work, then accessibility and flexibility of enterprise resources are improved, but vulnerability to cyberattacks and data leakage increases
Solution Approach 1:
The system segments the enterprise resource access environment by creating an isolated secure environment (CISE) within the user's personal device. This segmentation separates enterprise resources from ambient software and personal applications, allowing remote workers to access enterprise resources flexibly while preventing cyber threats from propagating between personal and enterprise data spaces.
Solution Approach 2:
The secure web browser (SWB) acts as an intermediary between the user's personal device and enterprise resources. It mediates all communications by routing traffic through a secure hub that enforces security policies, monitors user interactions, and controls data ingress and egress, thereby enabling accessibility while mitigating vulnerability to cyberattacks.
2Reliability
If comprehensive monitoring and control of user interactions is implemented, then security protection against cyber threats is improved, but system complexity and user convenience deteriorate
Solution Approach 1:
The system extracts security monitoring and control functions from the general operating system into a dedicated secure web browser and isolated secure environment. This extraction concentrates security mechanisms in a specialized component that provides comprehensive monitoring without complicating the overall system architecture, as the CISE acts as a self-contained security domain.
Solution Approach 2:
The secure hub automatically enforces security policies, monitors user interactions, and controls data flow without requiring user intervention. The system self-manages security operations including authentication, encryption, and threat detection, thereby providing robust security protection while maintaining user convenience despite the underlying complexity.
3Reliability
If an isolated secure environment is created to protect enterprise resources, then data security and integrity are improved, but ease of operation and accessibility worsen
Solution Approach 1:
The isolated secure environment is nested within the user's existing personal device operating system. The CISE embeds enterprise resource access capabilities inside the personal device's native environment, allowing users to access enterprise resources through their familiar personal devices without requiring separate hardware or complex configurations, thereby maintaining ease of operation while ensuring data security.
Solution Approach 2:
The secure web browser is designed to provide universal access to enterprise resources through a single interface that handles multiple functions including authentication, encrypted communication, policy enforcement, and resource access. This multi-functionality consolidates security and accessibility operations into one tool, improving ease of operation while maintaining data security within the isolated environment.

AI summary
A communications system for providing secure access to a digital resource of a group of digital resources accessible via a communications network, the system comprising: a data processing hub accessible via an IP (internet protocol) address; and a plurality of user equipment (UEs) useable to communicate via the communications network, each configured to have a cyber secure isolated environment (CISE) isolated from ambient software in the UE, and comprising a secure web browser (SWB); wherein the hub and CISE are configured so that digital resources in motion and at rest in CISE are visible to the hub.
