Managed Communication Privilege Isolation Through Context-Aware Policies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing managed communication services face challenges in securing high-volume machine-to-machine communications due to uniform privilege levels across all sessions, leading to increased security risks and inefficiencies, as well as difficulties in dynamically adapting to changing cyber security threats and performance requirements.
Innovation Solution
A context-aware policy engine monitors network traffic, dynamically adjusts communication privileges, establishes multiple secure tunnels, and adapts cryptographic methods to ensure minimum privilege levels and enhance security based on real-time threat levels and performance metrics, thereby providing privilege isolation and optimizing network resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If uniform privilege levels are applied across all communication sessions, then device complexity is reduced, but security risks increase due to inability to isolate privileges based on context
Solution Approach 1:
The patent segments communication sessions into different privilege levels based on context identification. The system identifies contexts (e.g., device type, user role, communication type) and assigns different privilege levels to different session contexts, enabling privilege isolation without requiring complex manual configuration. This segmentation allows the system to maintain security through differentiated privilege levels while reducing operational complexity through automated context-based assignment.
Solution Approach 2:
The patent implements local quality by assigning different privilege levels to different communication sessions based on their specific contexts. Instead of applying uniform privileges to all sessions, the system tailors privilege levels to match the specific requirements of each session context (e.g., higher privileges for critical business communications, lower privileges for routine transactions), thereby enhancing security where needed without unnecessarily complicating the overall system.
2Adaptability or versatility
If multiple secure tunnels are established dynamically, then communication security adapts to threat levels, but device complexity increases due to tunnel management
Solution Approach 1:
The patent implements dynamics by enabling the system to dynamically establish, modify, and terminate secure tunnels based on real-time threat level assessments and session contexts. The tunnel management system automatically adjusts security parameters and tunnel configurations in response to changing threat conditions, allowing the system to adapt its security posture without requiring manual intervention or complex static configurations.
Solution Approach 2:
The patent employs feedback mechanisms where the system continuously monitors security threats and session characteristics, then uses this information to adjust tunnel configurations and privilege levels accordingly. The feedback loop enables automatic adaptation of security measures based on observed conditions, reducing the need for complex manual tunnel management while maintaining high security standards.
3Reliability
If communication privileges are restricted based on context, then privilege isolation is achieved, but network performance may be impacted due to additional monitoring and control
Solution Approach 1:
The patent implements self-service by enabling the system to automatically monitor session contexts, identify appropriate privilege levels, and enforce restrictions without requiring manual configuration or intervention. The context-based privilege management system self-adjusts based on session characteristics and security policies, reducing the operational overhead associated with privilege isolation while maintaining effective security controls.
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting communication parameters (such as data encryption levels, transmission priorities, and access rights) based on identified session contexts. The system modifies these parameters automatically to balance security requirements with performance needs, allowing privilege isolation to be achieved through parameter differentiation rather than blanket restrictions that would unnecessarily impact network efficiency.

AI summary
A managed communication service system to restrict communication in a network based on a privilege associated to a context of the communication to provide privilege isolation. The managed communication service system comprises a processor; a memory; and an application stored in the memory that, when executed by the processor, is configured to monitor network traffic associated with the managed communication service system, determine a context of the managed communication service system based on monitoring the network traffic associated with the managed communication service system, restrict a first communication session provided by the managed communication service system based on the context to a first combination of communication privilege parameters, and restrict a second communication session provided by the managed communication service system based on the context to a second combination of communication privilege parameters.
