For more information, see Web threat protection. Custom indicator detections are also summarized in your organizations web threat reports under Web threat detections over time and Web threat summary. Web content filtering includes Web activity by category , Web content filtering summary , and Web activity summary. For more information, see Web content filtering.
Web protection is made up of the following components, listed in order of precedence. Each of these components is enforced by the SmartScreen client in Microsoft Edge and by the Network Protection client in all other browsers and processes. Similarly, during a conflict between indicators, allows always take precedence over blocks override logic.
That means that an allow indicator will win over any block indicator that is present. The table below summarizes some common configurations that would present conflicts within the web protection stack. It also identifies the resulting determinations based on the precedence listed above. Internal IP addresses are not supported by custom indicators. For a warn policy when bypassed by the end user, the site will be unblocked for 24 hours for that user by default.
This time frame can be modified by the Admin and is passed down by the SmartScreen cloud service. In all web protection scenarios, SmartScreen and Network Protection can be used together to ensure protection across both first and third-party browsers and processes.
SmartScreen is built directly into Microsoft Edge, while Network Protection monitors traffic in third-party browsers and processes. The diagram below illustrates this concept. Responses from the SmartScreen cloud are standardized.
Tools like Fiddler can be used to inspect the response from the cloud service, which will help determine the source of the block. When the SmartScreen cloud service responds with an allow, block, or warn response, a response category and server context is relayed back to the client. In Microsoft Edge, the response category is what is used to determine the appropriate block page to show malicious, phishing, organizational policy.
Kusto queries in advanced hunting can be used to summarize web protection blocks in your organization for up to 30 days. These queries use the information listed above to distinguish between the various sources of blocks and summarize them in a user-friendly manner. To list blocks that are due to other features like Custom Indicators , refer to the table above outlining each feature and their respective response category. These queries may also be modified to search for telemetry related to specific machines in your organization.
Note that the ActionType shown in each query above will show only those connections that were blocked by a Web Protection feature, and not all network traffic. If blocked by WCF or a custom indicator, a block page shows in Microsoft Edge that tells the user this site is blocked by their organization.

Refer to this article , and use the Add Roles and Features Wizard. When you get to the Features step of the wizard, select the Microsoft Defender Antivirus option. Once Microsoft Defender Antivirus is installed, your next step is to verify that it's running. On your Windows Server endpoint, run the following PowerShell cmdlet:.
To do that, run the following command from a command prompt:. The sc query command returns information about the Microsoft Defender Antivirus service. To get updated antimalware security intelligence, you must have the Windows Update service running.
You can change this configuration by using one of the following methods:. To ensure that protection from malware is maintained, we recommend that you enable the following services:.
The following table lists the services for Microsoft Defender Antivirus and the dependent services. Sample submission allows Microsoft to collect samples of potentially malicious software. To help provide continued and up-to-date protection, Microsoft researchers use these samples to analyze suspicious activities and produce updated antimalware Security intelligence. We collect program executable files, such as.
To enable automatic sample submission, start a Windows PowerShell console as an administrator, and set the SubmitSamplesConsent value data according to one of the following settings:.
To help ensure security and performance, certain exclusions are automatically added based on the roles and features you install when using Microsoft Defender Antivirus on Windows Server or , or Windows Server If you are using a non-Microsoft antivirus product as your primary antivirus solution on Windows Server, you must set Microsoft Defender Antivirus to passive mode or disabled mode. When you get to the Features step of the wizard, clear the Windows Defender Features option.
Microsoft Defender Antivirus will still run normally without the user interface, but the user interface cannot be enabled if you disable the core Windows Defender feature. Skip to main content. This browser is no longer supported. Download Microsoft Edge More info. Contents Exit focus mode.
