Detecting Shared Admin Credentials via Concurrent Session Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing privileged account management systems lack effective methods to detect when admin credentials are shared or compromised, particularly in scenarios where multiple individuals interact with multiple privileged sessions associated with a single administrator, posing a security risk to servers.
Innovation Solution
A method implemented by a privileged account management system that monitors and analyzes concurrent privileged sessions associated with the same administrator to detect simultaneous user input across multiple sessions, determining if the input could be provided by a single administrator, and taking corrective actions to mitigate potential security breaches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If admin credentials are shared among multiple administrators for flexible access, then ease of operation is improved, but security reliability deteriorates due to inability to track which administrator performed which task
Solution Approach 1:
The PAM system acts as an intermediary between administrators and servers, managing credential distribution and monitoring sessions. It issues time-limited credentials to specific administrators for specific tasks, and monitors the resulting sessions to track which administrator accessed which server and performed what actions, thereby maintaining both access flexibility and security accountability
Solution Approach 2:
The system implements feedback by monitoring administrator sessions and providing visibility into credential usage. The PAM system tracks session data including commands executed, files accessed, and actions performed, then reports this information to security officers and administrators, creating accountability while maintaining operational flexibility
2Reliability
If credentials are frequently changed to enhance security, then security reliability is improved, but productivity deteriorates due to repeated authentication requirements
Solution Approach 1:
The system implements dynamic credential management where credentials are issued with specific time limits and scopes based on the administrator's needs. Credentials automatically expire after a predetermined period or after the specific task is completed, providing strong security without requiring frequent manual credential changes. The PAM system handles the complexity of credential rotation automatically
Solution Approach 2:
The PAM system performs preliminary actions by pre-approving credential requests based on administrator roles and task requirements. Credentials are issued in advance for specific time periods and scopes, eliminating the need for repeated authentication during the credential's valid period while maintaining security through automatic expiration and scope limitations
3Reliability
If multiple privileged sessions are monitored to detect credential sharing, then security reliability is improved, but device complexity increases
Solution Approach 1:
The PAM system performs multiple functions within a single unified platform: it manages credential issuance, monitors privileged sessions, detects suspicious activities, generates reports, and provides alerting. This multi-functionality consolidates what would otherwise require multiple separate tools, reducing overall system complexity while providing comprehensive credential monitoring and security management
Data Source
AI summary
A privileged account management system can detect when credentials used to access one or more servers have been shared or otherwise compromised. This detection can occur through analysis of simultaneous actions that are performed via multiple sessions associated with the same administrator. When two or more sessions associated with the same administrator are opened, the interactions performed over each of the sessions can be monitored to identify whether such interactions could be performed by a single administrator. If it is determined that the interactions over the multiple sessions could not reasonably be performed by a single administrator, various actions can be taken to address the possible breach to the security of the one or more servers.
