Privileged Remote Access Session Risk Scoring and Dynamic Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack effective methods to protect shared Privileged Remote Access (PRA) sessions based on user risk, potentially introducing security risks to enterprise environments.
Innovation Solution
A system that receives invitations to join PRA sessions, determines the risk score of each user by referencing a user risk database, and either rejects or allows the invitations based on the risk score, while continuously monitoring and updating risk scores during the session.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If shared PRA sessions are allowed to improve collaboration and productivity, then user access flexibility increases, but security risk increases
Solution Approach 1:
The system performs preliminary risk assessment by determining risk scores for users before allowing them to join PRA sessions. This proactive approach evaluates user risk profiles in advance, preventing high-risk users from accessing privileged resources while allowing legitimate users to collaborate effectively.
Solution Approach 2:
The PRA system acts as an intermediary between users and privileged resources, implementing continuous risk monitoring and dynamic access control. This mediator evaluates user behavior in real-time and can revoke or restrict access when suspicious activity is detected, balancing collaboration needs with security requirements.
2Reliability
If continuous risk monitoring is implemented to improve security, then detection capability increases, but system complexity increases
Solution Approach 1:
The PRA system integrates multiple functions into a unified platform: user authentication, risk score determination, continuous behavior monitoring, dynamic policy enforcement, and session management. This multi-functional approach achieves comprehensive security monitoring without requiring separate complex systems for each function.
Solution Approach 2:
The system automatically determines risk scores and enforces access policies based on predefined criteria and continuous monitoring data. This self-service capability reduces the need for manual security management and complex human intervention, simplifying operations while maintaining high detection capabilities.

AI summary
Systems and methods to protect shared Privileged Remote Access (PRA) sessions based on user risk include receiving, at a Privileged Remote Access (PRA) system, one or more invitations from a host, the one or more invitations being for one or more users to join a PRA session; responsive to receiving the one or more invitations, determining a risk score of each of the one or more users associated with the one or more invitations; and rejecting or allowing each of the one or more invitations based on the risk score of each of the one or more users.
