Isolated Secure Browser Access for BYOD Cyber Protection
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 complicates cyber protection, making them susceptible to cyberattacks, especially in remote work scenarios.
Innovation Solution
A cybersecure system (CyberSafe) with a data and processing security hub and a secure web browser (SWB) in an isolated environment, monitoring and controlling data ingress and egress, enforcing security policies, and providing 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 are improved, but vulnerability to cyberattacks and difficulty of cyber protection increase
Solution Approach 1:
The system segments the device environment into a secure container isolated from the rest of the device. This container hosts the web browser and application virtual machines, creating a boundary that separates enterprise resources from potential threats on the personal device. The segmentation allows remote work accessibility while protecting against cyberattacks by confining threats to a limited scope.
Solution Approach 2:
The secure container acts as an intermediary layer between the personal device and enterprise resources. It mediates all communications and data exchanges, enforcing security policies and filtering traffic. This intermediary structure enables flexible remote access while maintaining security control, as all interactions must pass through the container's security mechanisms.
2Reliability
If a secure container with isolated web browser is implemented, then cyber protection and security control are improved, but device complexity and system overhead increase
Solution Approach 1:
The secure container is designed as a universal security framework that can host multiple different application virtual machines and support various web browsers. Rather than creating separate isolated environments for each application, the single container provides multi-functionality by dynamically loading different applications within the same isolated space, reducing overall system complexity.
Solution Approach 2:
The system implements a nested structure where application virtual machines are contained within the secure container, which itself is part of the host device operating system. This nesting allows multiple layers of isolation and control without requiring completely separate systems, managing complexity through hierarchical organization rather than flat multiplication of components.
3Reliability
If monitoring and control of data ingress and egress is enforced, then data security and prevention of data leakage are improved, but loss of information and operational restrictions increase
Solution Approach 1:
The system implements feedback mechanisms where the secure container continuously monitors data flows, user actions, and security events. This feedback is used to dynamically adjust security policies, alert administrators to potential threats, and automatically respond to security incidents. The feedback loop ensures data security while minimizing unnecessary restrictions by only blocking or alerting on actual threats rather than applying blanket restrictions.

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.
