The Developing Drivers with Windows Driver Foundation book is also available to help you learn the concepts and fundamentals of Windows Driver Frameworks (WDF). This book introduces Windows drivers and basic kernel-mode programming, and then describes the WDF architecture and programming model. It provides a practical, sample-oriented guide to using the frameworks to develop Windows drivers.
Windows Driver Frameworks (WDF) drivers consist of a DriverEntry routine and a set of event callback functions that are defined by the Windows Driver Framework objects that framework-based drivers use. The callback functions call object methods that the framework exports. The Windows Driver Kit (WDK) contains sample WDF drivers that demonstrate how to implement a driver's event callback functions. You can download these samples from the Windows Dev Center - Hardware. For information about what samples are available, see Sample KMDF Drivers and Sample UMDF Drivers.
Writing a driver using UMDF version 1 requires using the COM programming model to write C++ code. While UMDF version 2 is based on the same conceptual driver programming model as KMDF, UMDF 1 implements the model with different components, device driver interfaces (DDIs), and data structures. All new UMDF drivers should be written using UMDF 2. No new features are being added to UMDF 1 and there is limited support for UMDF 1 on newer versions of Windows 10 and Windows 11.
In contrast, starting in UMDF version 2, you can write a UMDF driver in the C programming language that calls many of the methods that are available to KMDF drivers. All of the interfaces that are shared between UMDF version 2 and KMDF have the same names, parameters, and structure definitions. If your driver uses only shared functionality, or uses conditional macros around calls that are only supported in one framework, you can write a single driver that you can compile with either UMDF or KMDF. For more information, see How to generate a UMDF driver from a KMDF driver.
Software-only kernel drivers do not use plug-and-play (PnP) to become associated with specific hardware IDs, and can run on any PC. Such a driver could be used for purposes other than the one originally intended, creating an attack vector.
The core activity of creating secure drivers is identifying areas in the code that need to be changed to avoid known software vulnerabilities. Many of these known software vulnerabilities deal with keeping strict track of the use of memory to avoid issues with others overwriting or otherwise comprising the memory locations that your driver uses.
To become familiar with code analysis, you can use one of the sample drivers for example, the featured toaster sample, -driver-samples/tree/main/general/toaster/toastDrv/kmdf/func/featured or the ELAM Early Launch Anti-Malware sample -driver-samples/tree/main/security/elam.
Static Driver Verifier (SDV) uses a set of interface rules and a model of the operating system to determine whether the driver interacts correctly with the Windows operating system. SDV finds defects in driver code that could point to potential bugs in drivers.
Note that only certain types of drivers are supported by SDV. For more information about the drivers that SDV can verify, see Supported Drivers. Refer to the following pages for information on the SDV tests available for the driver type you are working with.
Anyone can submit a questionable driver using the Microsoft Vulnerable and Malicious Driver Reporting Center. Refer to this blog entry for information on how drivers are submitted for analysis - Improve kernel security with the new Microsoft Vulnerable and Malicious Driver Reporting Center
Drivers live in the windows kernel, and having an issue when executing in kernel exposes the entire operating system. Because of this, pay close attention to driver security and design with security in mind.
UMDF (referred to as the framework in this article) is based on the component object model (COM). Every framework object must implement IUnknown and its methods, QueryInterface, AddRef, and Release, by default. The AddRef and Release methods manage the object's lifetime, so the client driver doesn't need to maintain the reference count. The QueryInterface method enables the client driver to get interface pointers to other framework objects in the Windows Driver Frameworks (WDF) object model. Framework objects perform complicated driver tasks and interact with Windows. Certain framework objects expose interfaces that enable a client driver to interact with the framework.
All software downloads are free, and most come with a Developer License that allows you to use full versions of the products at no charge while developing and prototyping your applications, or for strictly self-educational purposes. (Unless otherwise specified, our technical support organization will not provide technical support, phone support, or updates to you for the programs licensed under this agreement.) You can buy products with full-use licenses at any time from the online Store or from your sales representative.
The intent of the JDBC and ODBC drivers is to help users leverage the power ofBigQuery with existing tooling and infrastructure. Some capabilities ofBigQuery, including high performance storage integration andreservations management, are only available through the BigQueryAPIs. These drivers may only be used with BigQueryand may not be used with any other product or service.
In these days of social distancing, game developers and content creators all over the world are working from home and asking for help using Windows Remote Desktop streaming with the OpenGL tools they use. NVIDIA has created a special tool for GeForce GPUs to accelerate Windows Remote Desktop streaming with GeForce drivers R440 or later. Download and run the executable (nvidiaopenglrdp.exe) from the DesignWorks website as Administrator on the remote Windows PC where your OpenGL application will run. A dialog will confirm that OpenGL acceleration is enabled for Remote Desktop and if a reboot is required.
Different browsers require different drivers to allow WebDriver to communicate with and control them. See Platforms Supported by Selenium for more information on where to get browser drivers from, etc.
Note: It is still a good idea to follow these steps even if you previously installed selenium-webdriver and downloaded the browser drivers. You should make sure that everything is up-to-date.
Next, you need to download the relevant drivers to allow WebDriver to control the browsers you want to test. You can find details of where to get them from on the selenium-webdriver page (see the table in the first section.) Obviously, some of the browsers are OS-specific, but we're going to stick with Firefox and Chrome, as they are available across all the main OSes.
Next, you need to create a new instance of a driver, using the new webdriver.Builder() constructor. This needs to have the forBrowser() method chained onto it to specify what browser you want to test with this builder, and the build() method to actually build it (see the Builder class reference for detailed information on these features).
So this is pretty cool. We have tested this locally, but you could set this up on just about any server along with the relevant browser drivers, and then connect your scripts to it using the URL you choose to expose it at.

To get started, see Developing applications with DataStax drivers.This guide contains information about best practices, connecting to clusters, submitting queries with drivers, and handling client and server errors.
Starting January 2020, you can use the same DataStax driver for Apache Cassandra® (OSS), DataStax Enterprise, and DataStax Astra DB.DataStax has unified the DSE and OSS drivers to avoid user confusion and enhance the OSS drivers with some of the features in the DSE drivers.For more information, see the Better Drivers for Cassandra blog.
