Multi-Layer Kernel with Varied Privilege - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240134668 titled 'Multi-Layer Kernel with Varied Privilege

Simplified Explanation

The abstract describes a computer implemented method that involves loading two kernel layers with different privilege levels onto a hosting environment, isolating them from each other, and controlling access to memory protection tables.

  • Two kernel layers with different privilege levels are loaded onto a hosting environment.
  • The first kernel layer has a first privilege level, while the second kernel layer has a second privilege level different from the first.
  • The first kernel layer is isolated from the second kernel layer.
  • Access to a hosting environment memory protection table is controlled via the first kernel layer.

Potential Applications

This technology could be applied in:

  • Secure operating systems
  • Virtualization environments
  • Cloud computing platforms

Problems Solved

This technology addresses issues such as:

  • Unauthorized access to memory protection tables
  • Privilege escalation attacks
  • Security vulnerabilities in hosting environments

Benefits

The benefits of this technology include:

  • Enhanced security measures
  • Improved isolation between kernel layers
  • Better control over memory protection mechanisms

Potential Commercial Applications

This technology could be commercially applied in:

  • Data centers
  • Cybersecurity companies
  • Software development firms

Possible Prior Art

One possible prior art for this technology could be:

  • Hypervisor-based security mechanisms
  • Kernel-level access control systems

What are the specific technical details of the first and second privilege levels mentioned in the abstract?

The abstract does not provide specific technical details about the first and second privilege levels. Further information would be needed to understand the exact differences between these privilege levels and how they are implemented in the system.

How does the isolation of the first and second kernel layers contribute to the overall security of the hosting environment?

The abstract mentions that the first and second kernel layers are isolated from each other. This isolation helps prevent unauthorized access and privilege escalation between the two layers, enhancing the overall security of the hosting environment. However, the exact mechanisms and techniques used for this isolation are not detailed in the abstract.


Original Abstract Submitted

a computer implemented method includes loading a first kernel layer having a first privilege level onto a hosting environment. a second kernel layer having a second privilege level different from the first privilege level is also loaded onto the hosting environment. the first kernel layer is isolated from the second kernel layer and access to a hosting environment memory protection table is controlled via the first kernel layer.
