Abstract

Providing computer security is disclosed. A computing system is booted into a pre operating system environment. The pre operating system environment is used to provide current security data to the computing system. The computer system is booted into an operating system environment other than the pre operating system environment.

5. The method as recited in claim 1 , wherein the computing system is booted via a network into a pre-operating system environment by a device other than the computing system.

6. The method as recited in claim 1 further including:

creating an image; and

installing the image on the computing system;

wherein the current security data comprises an update to a local security data associated with the image.

7. The method as recited in claim 1 , wherein the current security data is provided via a network.

8. The method as recited in claim 1 , wherein the current security data is provided on a removable media.

9. The method of claim 1 , wherein the pre-operating system environment and the primary operating system environment of the computing system comprise separate operating system installations on the computing system.

10. The method of claim 1 , wherein the computing system comprises at least one of: a storage device, a digital video recorder, and a router.

11. A method for providing end point compliance, comprising:

establishing a connection from a computing system to a a network;

receiving, in response to detection of the connection by a server, a network address and a bootstrap program identifier at the computing system via the network;

downloading, automatically, a bootstrap program associated with the bootstrap program identifier and the network address;

receiving a pre-operating system at the computing system via the network by the bootstrap program, the pre-operating system selected automatically by the server based on type of the computing system;

booting the computing system into a pre-operating system environment using the received pre-operating system;

using the pre-operating system environment to perform a security check of the computing system to ensure it conforms with a security requirement stored in and received from an external repository that is not part of the pre-operating system environment or the operating system environment, wherein the security requirement is based on a plurality of factors including a type of the computing system;

rendering the computing system more secure with respect to a vulnerability associated with the primary operating system environment using the security requirement, wherein rendering the computing system more secure comprises configuring, using the pre-operating system environment, a firewall of the primary operating system of the computing system;

providing validation of the conformity with the security requirement using the pre-operating system environment, wherein validation comprises a credential checked by the network during an attempt by the computer system to connect to the network; and

determining based at least in part on the security check whether to boot the computing system into an operating system environment other than the pre-operating system environment.

12. The method as recited in claim 11 , further comprising using the pre-operating system environment, prior to the computing system being booted into the operating system environment other than the pre-operating system environment, to modify the computing system as required to conform to the requirement in the event the security check indicates the computing system does not conform to the security requirement.

13. A system for providing computer security including:

a processor configured to:

establish a connection from a computing system to a network;

receive, in response to detection of the connection by a server, a network address and a bootstrap program identifier at the computing system via the network;

download, automatically, a bootstrap program associated with the bootstrap program identifier and the network address;

receive a pre-operating system at the computing system via the network, the pre-operating system selected automatically by the server based on a type of the computing system;

boot the computing system into a pre operating system environment using the received pre-operating system;

use the pre-operating system environment to perform a security check of the computing system to ensure conformity with a security requirement received from a repository remote from the computing system;

use the pre-operating system environment to install onto the computing system a current security data stored in and received from the remote repository based at least in part on the security check, wherein the security data renders the computing system more secure with respect to a vulnerability associated with the primary operating system environment, rendering the computing system more secure comprising configuring, using the pre-operating system environment, a firewall of the primary operating system, wherein the security data is based on a plurality of factors including a type of the computing system; and
