Virtual Media Device for Secure VM Credential Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for communicating credential information to virtual machines (VMs) either require significant management overhead or compromise security, making it difficult to access and communicate with applications running in VM environments effectively.
Innovation Solution
A virtual media device is used to communicate information from outside a VM to applications within, employing a media image that is mounted and managed by an agent running in the VM, allowing secure and efficient transfer of messages and commands without exposing credential information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If credential information is communicated to the VM using existing methods, then the application can access the guest OS and communicate with applications, but management overhead increases or security is compromised
Solution Approach 1:
The patent introduces a virtual media device as an intermediary component between the host system and the VM guest OS. This virtual media device enables communication and credential verification without requiring direct exposure of credential information to the VM, thereby maintaining security while reducing management overhead. The virtual media device acts as a secure mediator that facilitates the necessary interactions without compromising the credential information.
2Ease of operation
If credential information is exposed to communicate with VM applications, then communication is enabled, but security is compromised
Solution Approach 1:
The virtual media device serves as a secure intermediary that enables communication with VM applications without exposing credential information. It mediates the authentication process by presenting credentials in a controlled manner, allowing the application to communicate with the VM while the actual credential information remains protected from exposure.
Solution Approach 2:
The patent uses a virtual media device that can present a copy or representation of the credential information without exposing the actual credentials. The virtual media device creates a secure copy that can be used for authentication and communication purposes while the original credential information remains safeguarded and inaccessible to the VM environment.
3Ease of operation
If management overhead is reduced, then ease of operation improves, but the ability to securely manage credential information may be compromised
Solution Approach 1:
The virtual media device implements self-service capabilities by automatically managing the credential information presentation and verification process. Once configured, the system can autonomously handle authentication and communication without requiring extensive manual management, thereby reducing management overhead while maintaining security through automated controlled access mechanisms.

AI summary
Disclosed are systems and methods for using a virtual media device to communicate messages to one or more applications running in a virtual machine (VM) without the need to expose credential information. Based on a media image having been mounted on a virtual media device of the VM, a notification may be generated to enable an agent in the VM to access the media image. The media image may include a message for one or more applications running in the VM. The agent may be configured to retrieve the message and to communicate the message to the one or more applications to enable the one or more applications to perform operations based on the message. The agent may be configured to eject the virtual media device based on completion of the operations.
