Embodiment Construction

[0012] This article discusses securing operating system configuration values. During the process of booting a device, a set of configuration values ​​used by at least a portion of the device's operating system or operating systems (and optionally including one or more configuration values ​​used by components of the device's pre-operating system environment) configuration value) is checked against the device's policy. If the configuration value satisfies the policy, then allow the operating system to run on the device, but if the configuration value does not satisfy the policy, take one or more appropriate actions (e.g., do not run the operating system described above, changing the value described, etc.). The policy is stored in a manner that prevents unauthorized modification by the operating system and other applications running on the computing device. However, one or more policy issuers may update the policy, allowing the policy to change over time.

Abstract

In a pre-operating system environment of a device, a policy identifying configuration settings for the operating system is obtained prior to loading and running the operating system on the device. The operating system itself is prevented from changing this policy, but may be changed by components of the pre-OS environment under certain circumstances. This policy is compared to configuration values ​​used by the operating system, and if the configuration values ​​satisfy the policy, the operating system is allowed to boot with the configuration values. However, if the configuration does not satisfy the policy, then responsive action is taken.

Description

technical field [0001] The present invention generally relates to the technical field of operating system security. Background technique [0002] Computers are becoming increasingly interconnected via various networks, such as the Internet. While this connectivity allows users to access a variety of services and data, this connectivity is not free from its own problems. One such problem is that this connectivity can allow malicious programs to run on these computers. These malicious programs can perform various unwanted actions, such as launching attacks on other computers, sending private data to other users' computers, preventing a user from being able to use his or her computer, and so on. It is currently still difficult to protect a computer from such malicious programs. Contents of the invention [0003] This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is n...
