Secure Browser Synchronization Across Isolated BYOD Environments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increased vulnerability of Bring Your Own Device (BYOD) and workplace user equipment (WPUE) to cyberattacks due to their untethered nature and varied software configurations complicates the provision of cyber protection for enterprise data, especially in remote work scenarios, where multiple networks and cloud services are accessed.
Innovation Solution
A cybersecure system, CyberSafe, is implemented, comprising a secure web browser (SWB) within an isolated secure environment (CISE) on UEs, which monitors and controls data ingress and egress, enforces security policies, and integrates with a cloud-based hub for enhanced visibility and protection, using features like anti-injection software, risk estimation, and Single-Sign-On (SSO) to manage access and mitigate cyber threats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If BYOD and WPUE are allowed for remote work access, then employee convenience and productivity are improved, but vulnerability to cyberattacks and security risks increase
Solution Approach 1:
The system segments the UE into multiple isolation environments: a secure environment for enterprise resources and a less secure environment for personal use. This segmentation allows remote work access convenience while containing cyber threats within specific environments, preventing them from affecting the entire device.
Solution Approach 2:
The secure browser acts as an intermediary between the user and enterprise resources, mediating all access requests through a controlled interface. This intermediary enforces security policies and monitors communications, enabling convenient remote access while maintaining security controls against cyberattacks.
2Adaptability or versatility
If multiple networks and cloud services are accessed for remote work, then work flexibility and productivity are improved, but complexity of providing cyber protection increases
Solution Approach 1:
The secure browser provides universal security protection across multiple networks and cloud services through a single unified interface. It implements comprehensive security policies including encryption, authentication, and threat detection that work consistently across diverse remote work environments, simplifying cyber protection despite increased flexibility requirements.
3Reliability
If secure isolation environment is implemented on UE, then cyber security protection is improved, but device resource consumption and operational complexity increase
Solution Approach 1:
The system dynamically manages isolation environments based on usage context, activating secure environments only when enterprise resources are accessed and deactivating them when not needed. This dynamic approach maintains high security reliability while reducing device resource consumption during personal use periods.

AI summary
A communications system for providing secure access to a digital resource of a group of digital resources accessible via the internet, 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 internet, 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.
