Introduction

These requirements are Microsoft s guidelines for designing Windows Filtering Platform Drivers (WFP), File Systems Filter Drivers, Antivirus Filter Drivers, and Early Launch Anti-Malware (ELAM Filter Drivers). Successfully following this guidance allows a partner to receive certification and signing for their filter drivers.

The requirements are organized by feature using a Camel Case naming convention, which facilitates grouping related requirements and communicating their relationship to the Windows feature they are intended to support. Tests assessing compliance with the features are exposed during testing with the Hardware Certification Kit and can be related directly back to these requirements. Some requirements have passed forward from Logo requirements for earlier Windows versions which used a category based structure. We have included the older LogoPoint ID in the comments section for your convenience.

Optional Features and "If Implemented" Requirements

The Windows Hardware Certification Kit (Windows HCK) automatically detects all features that are implemented in a product. When the detected features include all required features that are needed to define a product type, then the product is certifiable for that product type.

If additional functionality is implemented in the filter driver design beyond the minimum list of features and their underlying requirements for a given product type, then the Windows HCK identifies those additional features and tests them for compliance with the corresponding requirements. Because these optional requirements apply only if the optional features are implemented, these requirements are identified as "If Implemented" in this document. If an optional feature is exposed, the associated "If implemented" requirements must be met for the filter driver to be successfully certified.

Applies to
Windows 8 Client x86, x64
Windows 8.1 Client x86, x64
Windows Server 2012 R2 x64
Windows Server 2012 x64

Description

The AM driver is critical to the boot success of the computer. If the driver gets corrupted, then the boot may not succeed. To provide the best user experience, it is required that when the AM driver is installed, it also installs a copy in the driver backup store. This ensures a smooth remediation experience in the case that the primary driver gets corrupted.The location of the ELAM backup store is defined by Windows, and stored in the registry:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\EarlyLaunch ! BackupPath Design Notes:The early launch anti-malware (AM) drivers are started soon after the NTOS kernel starts. For each subsequent boot driver the AM driver receives a callback from the PnP manager to determine whether the boot driver should be initialized. The AM driver evaluates the boot driver and must return good, bad, or unknown. Based on the returned classification and defined policy, the PnP manager decides whether to initialize the boot driver.

Description

ELAM files need to be signed with a special signature as part of the submission process. The process of determining what signature each module needs is being standardized; each INF file now must include a SignatureAttributes section uniquely identifying what type of signature is applicable for the associated driver binaries. Adding this section to existing inf files is a very simple process.

An example follows:

[SignatureAttributes]

Target Feature
Filter.Driver.WindowsFilteringPlatform
Applies to
Windows 7 Client x86, x64
Windows 8 Client x86, x64
Windows 8.1 Client x86, x64

Description

The Windows Filtering Platform (WFP) includes a Network Diagnostics Framework (NDF) helper class, called the Filtering Platform helper class (FPHC). FPHC can help identify the root causes of connectivity issues caused by WFP. A host firewall can invoke its own NDF helper class. FPHC extensibility allows these third-party helper classes to be invoked during diagnostics.FPHC can identify WFP as the cause of a connectivity issue. If available, FPHC can also identify the provider that created the filter that is blocking network traffic. FPHC passes this information to NDF, which in turn can then notify the user that WFP is causing the connectivity problem and give the name of the provider blocking traffic.However, the FPHC cannot suggest a corrective action to the user, nor can it provide the reason that the filter is blocking traffic to the user. Only a FPHC extension can perform those tasks.Host firewalls must be able to successfully diagnose the inbound/outbound connection failures caused due to the host firewall, and provide an appropriate response to the end-user based on the diagnosis. (eg. Repair mechanism, message explaining to the user the reason why the connection failed, etc).Design Notes:More information regarding NDF and FPHC can be found in the following links:NDF : https://go.microsoft.com/fwlink/?LinkID=125463&clcid=0x409FPHC : https://go.microsoft.com/fwlink/?LinkID=125464&clcid=0x409

Target Feature
Filter.Driver.WindowsFilteringPlatform
Applies to
Windows 7 Client x86, x64
Windows 8 Client x86, x64
Windows 8.1 Client x86, x64

Description

Firewalls may use callouts to modify and re-inject network packets, when filtering at any layer. One or many host firewalls may be present on the same system. In the case where only one host firewall is present on the system, continually modifying & re-injecting the same packets may result in reduced performance and is to be avoided. In the case where multiple host firewalls (with callouts) are present on the system, the same network packet(s) may continually be modified by multiple callouts, When a host firewall continually modifies and reinjects the same packet it may result in the network packet never getting processed and could potentially create a deadlock, which is to be avoided. Host firewalls must not modify and reinject the same network packet more than 2 times per layer. If such a situation occurs, host firewalls may choose to let the packet go through, or drop the network packet.

Windows 7 Client x86, x64
Windows 8 Client x86, x64

Description

Host firewalls are provided the ability to selectively turn parts of Windows Firewall on or off. These parts specify different types of rules (and subsequently filter sets), and may also be referred to as categories. Filter sets that may be selectively turned off are Boot-Time Filters, Firewall Filters, Connection Security Filters, and Stealth Filters. The 'Register' interface is supported by the HNetCfg.FwProducts COM object. The put_DisplayName() call must be used to fill in your product information. Before turning off the firewall rules category, vendor firewalls must ensure that all filters must be installed. This requirement ensures better interoperability with Windows. In addition, if all installed host firewalls on the system are uninstalled for any reason, Windows Firewall is aware of this, and will automatically turn on the firewall filters, ensuring that the system is always protected. The Connection Security filters need to remain enabled to keep Windows scenarios protected. Specifically, the Connection Security filters ensure that the system supports communications which require authentication and encryptionDesign Notes: This requirement ensures that firewall vendors disable Windows Firewall per documented guidelines.
