Privileged Remote Access in Zero Trust Private Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional enterprise network security models, which rely on a well-defined perimeter, are inadequate in the era of cloud-based applications and mobile users, leading to increased security risks due to unsecured devices and unmanaged access to the Internet.
Innovation Solution
Implementing a cloud-based system that applies a zero trust architecture with policy-based privileged remote access, using a zero trust network access (ZTNA) approach to secure connections, monitor traffic, and enforce access controls based on context, ensuring all traffic is inspected and validated before reaching its destination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional perimeter-based network security model is used, then users within the perimeter can access resources easily, but security risks increase when users access the Internet and cloud applications
Solution Approach 1:
The patent segments the network perimeter into multiple virtual network perimeters, allowing different security policies to be applied to different segments. This enables users to access resources in secure segments while isolating them from high-risk segments, thus maintaining ease of access while reducing security risks through network segmentation and virtualization
Solution Approach 2:
The patent introduces security appliances and virtual network perimeters as intermediaries between users and the Internet/cloud applications. These intermediaries filter and monitor traffic, allowing users to access cloud resources while the intermediary layer blocks malicious content and enforces security policies, thus maintaining access while reducing security risks
2Object-affected harmful factors
If cloud-based security solutions are implemented, then security risks are reduced, but network complexity increases
Solution Approach 1:
The patent implements universal cloud-based security appliances that can be deployed across multiple network perimeters and provide multiple security functions (firewall, intrusion prevention, content filtering, etc.) in a single platform. This reduces network complexity by consolidating security functions while maintaining comprehensive security risk protection across the enterprise network
3Object-affected harmful factors
If zero trust architecture is implemented, then security is enhanced by treating all traffic as hostile, but access control complexity increases
Solution Approach 1:
The patent implements dynamic access control policies in the zero trust architecture that automatically adjust based on user identity, device state, location, and risk assessment. This dynamic approach simplifies access control complexity by using automated policy enforcement and context-aware authentication rather than static, manually configured rules, while maintaining enhanced security through continuous verification
