Bridging the Gap Between Software and Hardware Techniques for I/O Virtualization | 2008-06-21 | USENIX Association |
| The paravirtualized I/O driver domain model, used in Xen, provides several advantages including device driver isolation in a safe execution environment, support for guest VM transparent services including live migration, and hardware independence for guests. However, these advantages currently come at the cost of high CPU overhead which can lead to low throughput for high bandwidth links such as 10 gigabit Ethernet. This paper shows how to significantly narrow the performance gap by improving the performance of the driver domain model. In particular, they reduce execution costs for conventional NICs by 56% on the receive path, and they achieve close to direct I/O performance for network devices supporting multiple hardware receive queues.

A Type System for Data-Flow Integrity on Windows Vista | 2008-06-08 | Association for Computing Machinery |
| The Windows Vista operating system implements an interesting model of multi-level integrity. The paper observes that in this model, trusted code must participate in any information-flow attack. Thus, it is possible to eliminate such attacks by statically restricting trusted code. The paper formalizes this model by designing a type system that can efficiently enforce data-flow integrity on Windows Vista. Typechecking guarantees that objects whose contents are statically trusted never contain untrusted values, regardless of what untrusted code runs in the environment. Some of Windows Vista's runtime access checks are necessary for soundness; others are redundant and can be optimized away.

School District Enhances Learning and Saves on IT Costs With Latest Operating System | 2008-06-01 | Microsoft |
| Tri-Center Community Schools educates 900 K - 12 students on one campus in southwest Iowa. By upgrading its computers to the Windows Vista operating system, the district provided teachers with state-of-the-art multimedia capabilities for creating more engaging learning experiences that better prepare students for college and work. Deploying Windows Vista also has helped to reduce desktop deployment, management, and support time.

Medical Device Company Boosts Security and Efficiency With New Operating System | 2008-05-01 | Microsoft |
| Kinex Medical Company designs and manufactures medical devices that reduce medical costs by providing early rehabilitation in patients' homes. In 2006, Kinex deployed an electronic records system based on Microsoft Office SharePoint Server 2007, achieving significant cost savings. Then, in 2007, Kinex upgraded its PCs from Windows XP to the Windows Vista Enterprise operating system for further IT enhancements. By doing so, Kinex has bolstered its ability to protect its network against security breaches and to safeguard patient data. Provisioning new computers is up to five times quicker, and overall efficiency has risen with faster, easier searching and fewer operating system issues.

Increasing System Power Efficiency Through Driver Support for Runtime Idle Detection | 2008-04-23 | Microsoft |
| One way to improve a computer's power efficiency is to power down devices that aren't currently being used, even though the system may still be active and in its normal operating power state (S0). The practice of powering down an idle device while the system remains running is referred to as "Runtime idle detection" or "S0 idle." A USB function driver supports runtime idle detection by implementing USB selective suspend. This white paper provides advice for driver developers on how to modify their function drivers to support runtime idle detection.

Selective Suspend in USB Drivers | 2008-03-23 | Microsoft |
| A USB function driver supports runtime idle detection by implementing USB selective suspend. This white paper provides guidance for driver developers on how to implement selective suspend in USB drivers that are based on the Windows Driver Foundation (WDF). Selective suspend is the ability to power down and later resume an idle USB device while the computer to which it is attached remains in the working state (S0).

Windows Authenticode Portable Executable Signature Format | 2008-03-21 | Microsoft |
| Authenticode is a digital signature format that is used to determine the origin and integrity of software binaries. Authenticode is based on Public-Key Cryptography Standards (PKCS) #7 signed data and X.509 certificates to bind an Authenticode-signed binary to the identity of a software publisher. This paper contains the structure and technical details of the Authenticode signature format. This paper does not discuss issuing or processing X.509 code signing certificates, use of Windows Software Development Kit tools to sign binaries, deployment of a code signing infrastructure, or related Windows APIs. Information on these topics is available in "Resources" at the end of this paper.
