Appl. No.:

10/881830
Inventors:

Steven L. Grobman - El Dorado Hills CA, US
Assignee:

Intel Corporation - Santa Clara CA
International Classification:

G06F 9/455
G06F 9/46
G06F 11/00
US Classification:

718 1, 718100, 718104, 718105, 718108, 714 7, 714 8, 714 21, 714 37, 714 39

US Patent:

7669229, Feb 23, 2010
Filed:

Nov 13, 2002
Appl. No.:

10/294126
Inventors:

Steven L. Grobman - El Dorado Hills CA, US
Assignee:

Intel Corporation - Santa Clara CA
International Classification:

H04L 9/32
US Classification:

726 2, 726 1, 726 3, 726 6, 726 12, 726 14, 726 25, 726 27, 709225, 709227, 709229
Abstract:

It is convenient to allow access to a private network, such as a corporate intranet, or outward facing extranet application, from an external network, such as the Internet. Unfortunately, if an internal authentication system is used to control access from the external network, it may be attacked, such as by a malicious party intentionally attempting multiple invalid authentications to ultimately result in an attacked account being locked out. To circumvent this, an authentication front-end, proxy, wrapper, etc. may be employed which checks for lockout conditions prior to attempting to authenticate security credentials with the internal authentication system.

Method, Apparatus And System For Enhanced Cpu Frequency Governers

US Patent:

7739532, Jun 15, 2010
Filed:

Sep 7, 2006
Appl. No.:

11/518004
Inventors:

Steven L. Grobman - El Dorado Hills CA, US
Assignee:

Intel Corporation - Santa Clara CA
International Classification:

G06F 9/455
G06F 1/00
US Classification:

713322, 718 1
Abstract:

A method, apparatus and system enable enhanced processor frequency governors to comprehend virtualized platforms and utilize predictive information to enhance performance in virtualized platforms. Specifically, in one embodiment, an enhanced frequency governor in a virtual host may run within a virtual machine on the host and interact with a virtual machine manager to collect predictive information from application(s) running within each virtual machine on the host. The enhanced frequency governor may then utilize the predictive information to determine future CPU frequency requirements and raise or lower the CPU frequency and/or voltage in anticipation of the needs of the various applications.

Exclusive Access For Secure Audio Program

US Patent:

7752436, Jul 6, 2010
Filed:

Aug 9, 2005
Appl. No.:

11/200662
Inventors:

Steven Grobman - El Dorado Hills CA, US
David Grawrock - Aloha OR, US
Narendar B. Sahgal - Portland OR, US
Joe Gruber - West Chester OH, US
Assignee:

Intel Corporation - Santa Clara CA
International Classification:

H04L 29/06
US Classification:

713164, 718108
Abstract:

Executing a monitor on a platform, the monitor capable of providing exclusive, secure access to an audio I/O device of the platform, executing a first partition on the platform, providing an audio device model in the first partition by directly mapping the audio I/O device from the monitor to the first partition for applications executing in the first partition, and providing exclusive, secure access to the audio I/O device to a program performing an audio function in a secure mode in the first partition.

Method, Apparatus And System For Virtualized Peer-To-Peer Proxy Services

US Patent:

7788713, Aug 31, 2010
Filed:

Jun 23, 2004
Appl. No.:

10/875833
Inventors:

Steven Grobman - El Dorado Hills CA, US
Carl C. Jones - Folsom CA, US
Assignee:

Intel Corporation - Santa Clara CA
International Classification:

G06F 9/455
G06F 9/00
US Classification:

726 12, 718 1, 726 2, 726 11, 726 26, 726 27, 726 30
Abstract:

A method, apparatus and system for virtualized proxy services are disclosed herein. Specifically, on one embodiment, a virtual proxy may be implemented in a virtual machine host. The virtual proxy may reside within a dedicated or shared virtual partition and may include a set of access restrictions. In one embodiment, a network including virtual machine hosts having virtual proxies may also provide additional peer-to-peer services. More specifically, a virtual proxy on a virtual host may be configured to broadcast/multicast content requests to other virtual hosts on the network prior to accessing the content from a remote location. If the content has previously been downloaded by another virtual host on the network, the virtual proxy on the requesting host may copy the content from the peer virtual host, instead of downloading the content from the remote location again. A variety of security measures may be implemented in one embodiment to ensure data integrity.

Method And Apparatus To Detect Kernel Mode Rootkit Events Through Virtualization Traps

US Patent:

7845009, Nov 30, 2010
Filed:

May 16, 2006
Appl. No.:

11/435463
Inventors:

Steven Grobman - El Dorado Hills CA, US
Assignee:

Intel Corporation - Santa Clara CA
International Classification:

G06F 21/22
G06F 11/30
G06F 9/445
US Classification:

726 24, 718 1
Abstract:

Detecting a rootkit in a computing system may be achieved by detecting, by a virtual machine monitor, a virtualization trap occurring as a result of an action by a rootkit executing in a computing system; and analyzing the virtualization trap to detect the presence of the rootkit in the computing system. Action may then be taken to block the rootkit activity to safeguard the computing system.

US Patent:

7904903, Mar 8, 2011
Filed:

Jun 30, 2005
Appl. No.:

11/174254
Inventors:

Steven L. Grobman - El Dorado Hills CA, US
Michael D. Kinney - Olympia WA, US
Assignee:

Intel Corporation - Santa Clara CA
International Classification:

G06F 9/455
G06F 9/46
US Classification:

718 1, 718108
Abstract:

In some embodiments, the invention involves saving limited context information when transitioning between virtual machines. A predetermined set of instructions and events cause a trap. A bit or flag is set to indicate that the event has occurred within a virtual machine. The virtual machine monitor determines whether specific register sets must be saved or restored upon a context switch, based on whether the flag has been set. Other embodiments are described and claimed.
