Virtual Machine Isolation for Host Security Against Zero-Day Attacks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current computer security measures, such as anti-virus and anti-malware programs, are inadequate in preventing persistent infections from viruses, Trojan horses, and other attack vectors, as they can only react to known threats and take days or weeks to provide protection, leading to significant damage such as data breaches and financial losses.
Innovation Solution
The use of virtual machines to create an isolated, protected environment for executing applications, where a management tool automatically selects and configures virtualized hardware, operating systems, and security software to run applications, thereby isolating the host system from potential infections, and automatically reverts to a clean state after use, providing a 'one-click' solution for infection-free data processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional security programs (anti-virus, anti-malware) are used to protect computers, then they can detect and remove known threats, but they take days or weeks to respond to new threats and cannot prevent zero-day attacks
Solution Approach 1:
The system performs preliminary actions by creating a clean virtual machine environment before any potential infection can occur. The virtual machine is pre-configured with security software and a known-clean operating system state, allowing it to safely execute suspicious applications or access questionable web content without risking the host system. This preliminary preparation enables immediate response to new threats without waiting for security updates.
Solution Approach 2:
The virtual machine acts as an intermediary layer between the user/host system and potentially malicious content. Instead of directly executing suspicious applications or accessing untrusted websites on the host system, the virtual machine mediates these interactions, containing any potential infections within its isolated environment while still allowing the user to access the content through the virtualized interface.
2Ease of operation
If users directly execute applications or access web content on the host system, then they can use the full functionality of their computer, but they risk infection from viruses, Trojan horses, and other attack vectors
Solution Approach 1:
The system segments the computing environment by separating the host system from the application execution environment through virtualization. The virtual machine creates an isolated partition where applications and web content can be executed with restricted access to host system resources. This segmentation allows users to maintain full functionality within the virtual environment while the host system remains protected from direct exposure to harmful factors.
Solution Approach 2:
The virtual machine creates an inert or isolated environment for executing potentially harmful applications or accessing suspicious web content. Within this virtualized atmosphere, the host system is effectively disconnected from direct interaction with malicious code, similar to how an inert gas atmosphere protects reactive substances. Any infections occurring within the virtual machine cannot escape to affect the host system.
3Reliability
If security updates are deployed to protect against new threats, then protection coverage improves, but the process takes days or weeks to complete
Solution Approach 1:
The system creates a copy of the operating system and application environment within the virtual machine that is known to be clean and can be rapidly deployed. Instead of waiting for security updates to propagate through the host system, the virtual machine is instantiated with a fresh, pre-configured image that includes the latest security measures. This copying approach allows immediate protection without the time-consuming update deployment process.
Solution Approach 2:
The virtual machine environment is designed as a disposable, short-lived container that can be quickly created, used, and destroyed. Rather than maintaining a permanently updated host system that requires lengthy update cycles, the system creates new virtual machine instances as needed, each with its own clean environment. These virtual machines can be rapidly provisioned and discarded, eliminating the time delay associated with traditional security update deployment.
Data Source
AI summary
A processing system including a host system having a host processor, an associated host memory system, user interface, and a host operating system. The host operating system runs a virtualization program for creating a virtual machine including virtual hardware, a virtual operating system, and a virtual application program running in conjunction with the virtual operating system. The virtual machine instantiates the virtual application program in response to a user request through the user interface to initiate a function. In response to user inputs through the user interface, the virtual machine executes operations with the virtual application in conjunction with the virtual operating system to implement the requested function such that the host system is isolated from an attack initiated during execution of the virtual application program by the virtual machine.
