FPCH Admin AWS Posted August 18, 2022 FPCH Admin Posted August 18, 2022 (edited) Over the last two years, the world has dramatically changed both in our daily lives and how companies conduct business. In the pre-pandemic world, eroding network boundaries and the maturity of SaaS applications precipitated endpoint-first design. The pandemic and post-pandemic era demand it, the world is embracing hybrid workplaces and zero trust postures. When we first launched Network Protection for Windows and built powerful Web Protection and Microsoft Defender for Cloud Apps (MDA) capabilities on top of it, we knew our vision to bring you our proxy-less endpoint first architecture would remain incomplete until we delivered for macOS and Linux. That day has arrived, and we could not be more excited to share that Network and Web Protection for macOS and Linux is now in Public Preview. Network Protection helps reduce the attack surface of your devices from Internet-based events. It prevents employees from using any application to access dangerous domains that may host phishing scams, exploits, and other malicious content on the Internet. It is the foundation on which our Web Protection for Microsoft Defender for Endpoint is built. These capabilities include Web threat protection, Web content filtering, and IP/URL Custom indicators. Web protection enables you to secure your devices against web threats and helps to regulate unwanted content. Network protection also integrates Microsoft Defender for Endpoint with Defender for Cloud Apps natively. Currently, the integration for macOS and Linux only supports endpoint enforcement capabilities. How to evaluate Network Protection and the features it enables: Explore Network Protection on macOS Prerequisites & Requirements Licensing: Microsoft Defender for Endpoint tenant (can be trial) Onboarded Machines: Minimum macOS version: 11 (Big Sur) MDE product version: 101.78.13 Your device must be in the InsiderSlow or InsiderFast Microsoft AutoUpdate update channel. You can check the update channel using the following command: mdatp --health releaseRing If your device is not already in the InsiderSlow update channel, execute the following command from the Terminal. The channel update takes effect next time the product starts (when the next product update is installed or when the device is rebooted). defaults write com.microsoft.autoupdate2 ChannelName InsiderSlow Alternatively, if you are in a managed environment (JAMF or Intune), you can configure the device group remotely.

Once the prerequisites have been met, follow installation and configuration instructions in Use network protection to help prevent macOS connections to bad sites | Microsoft Docs Here is how the experience looks on macOS: Explore Network Protection on Linux Prerequisites & Requirements Licensing: Microsoft Defender for Endpoint tenant (can be trial) and platform specific requirements found in Microsoft Defender for Endpoint for non-Windows platforms | Microsoft Docs Onboarded Machines: Minimum Linux distro version: refer to Microsoft Defender for Endpoint on Linux Microsoft Defender for Endpoint Linux client version: 101.78.13-insidersfast Once the prerequisites have been met, follow installation and configuration instructions in Use network protection to help prevent Linux connections to bad sites | Microsoft Docs How do I verify my Mac/Linux device is configured properly? Navigate to SmartScreen Test which will block the browser from loading the page. On macOS an accompanying toast message will also be shown. On Linux the connection will be disallowed as shown below. There will be no accompanying toast message in Linux: Alternatively, you can also test this from the Terminal by running the following command and noticing that the connection is blocked by the Network Protection: curl SmartScreen Test How do I explore the features? Protect your organization against web threats | Microsoft Docs Web threat protection is part of Web protection in Microsoft Defender for Endpoint. It uses network protection to secure your devices against web threats. [*]Run through the IP/URL Custom Indicators of Compromise flow to get blocks on the Custom Indicator type. [*]Explore Web content filtering | Microsoft Docs Note: if you are removing a policy or changing device groups at the same time, this might cause a delay in policy deployment. Pro Tip: You can deploy a policy without selecting any category on a device group. This action will create an audit only policy, to help you understand user behavior before creating a block policy. [*]Integrate Microsoft Defender for Endpoint with Cloud App Security | Microsoft Docs and your Linux and macOS devices with Network Protection enabled will have endpoint policy enforcement capabilities. Note: Discovery and other features are currently not supported on macOS and Linux platforms. On device experience When an end user attempts to access monitored domains on macOS/Linux, their navigation effort will be audited/blocked (depending on Network Protection policy). On macOS, the user will also be informed by Microsoft Defender for Endpoint via toast. macOS The user will get a plain block experience accompanied by the following toast message which will be displayed by the operating system including the name of the blocked application or website (e.g Blogger.com) No block pages are shown in third-party browsers, and the user sees a "Secure Connection Failed' page along with a toast notification. Depending on the policy responsible for the block, a user will see a different message in the toast notification. For example, web content filtering will display the message 'This content is blocked'. We are looking forward to hearing your feedback and answering any questions you may have!
