Virtual Machine Secure Access via Management Appliance Trust
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing secure access to virtual machine images in distributed computing systems is complex and prone to cyber attacks due to the need for additional authentication credentials when accessing virtual machines dispatched across multiple physical machines.
Innovation Solution
Establishing a trusted relationship between a management appliance and a virtual machine using public key cryptography, allowing authenticated users to access the virtual machine without further credentials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard security features such as login identification and passwords are used for accessing virtual machines, then security authentication is provided, but the access management becomes tedious and time consuming
Solution Approach 1:
The system performs preliminary authentication by establishing trust relationships between the management appliance and virtual machines before access is needed. The management appliance automatically authenticates to virtual machines using pre-configured credentials, eliminating the need for users to manually provide authentication credentials during access operations.
Solution Approach 2:
The management appliance automatically manages authentication credentials and performs self-service authentication to virtual machines. The system autonomously handles the authentication process without requiring user intervention, where the management appliance itself manages the credential distribution and verification processes.
2Reliability
If security measures are adapted to the physical location of virtual machines across multiple physical machines, then security coverage is improved, but the complexity of security management increases
Solution Approach 1:
The management appliance serves as a universal authentication authority that can authenticate to multiple virtual machines across different physical hosts using a single integrated system. The appliance implements multi-functional security management including credential distribution, trust relationship establishment, and access control across the entire virtualized environment from a centralized location.
Solution Approach 2:
The management appliance acts as an intermediary between administrators and virtual machines,以及between different physical hosts. It mediates authentication by holding and managing credentials centrally, then providing authenticated access to virtual machines without requiring administrators to directly manage credentials on each physical host or virtual machine.
3Productivity
If virtual machine images are dispatched across multiple physical machines, then resource utilization is improved, but the movement and management of virtual machines becomes more complicated
Solution Approach 1:
Virtual machines perform self-service authentication by automatically accepting credentials from the management appliance. When virtual machine images are dispatched or migrated across physical machines, they autonomously establish trusted relationships with the management appliance without requiring manual reconfiguration or administrator intervention, enabling seamless mobility.
Solution Approach 2:
The system implements feedback mechanisms where the management appliance continuously monitors and manages credential validity across the distributed environment. When virtual machines are dispatched or migrated, the appliance automatically updates trust relationships and maintains security policies, providing real-time feedback on authentication status and enabling dynamic adaptation to changing system configurations.
