### Summary of the Video: Microsoft Defender for Endpoint - Network Protection **Overview of Network Protection:** - Network Protection (NP) in Microsoft Defender for Endpoint (MDE) shields devices from internet-based threats as part of the **Attack Surface Reduction (ASR)** features. - It leverages **Microsoft Defender SmartScreen** to block harmful domains and URLs, extending its protection beyond web browsers to other applications. --- ### **Core Features of Network Protection:** 1. **Web Threat Protection:** Prevents access to malicious websites. 2. **Custom Indicators:** Allows admins to define specific IPs, URLs, or domains to block or allow. 3. **Web Content Filtering:** Blocks access to websites based on categories like gambling, peer-to-peer sharing, or adult content. **Modes of Operation:** - **Audit Mode:** Logs events without blocking access. - **Block Mode:** Actively blocks harmful websites and applications. --- ### **How It Works:** 1. **URL Reputation Scenarios:** - **Good Reputation:** Access is allowed. - **Unknown/Uncertain Reputation:** Access is blocked with an option for the user to unblock temporarily. - **Malicious Reputation:** Access is fully blocked with no unblock option. 2. **Command and Control (C2) Protection:** - Detects and blocks C2 infrastructure used in ransomware or malware attacks. --- ### **Configuration Methods:** 1. **Microsoft Defender Portal:** - Add custom indicators (URLs, domains, or IPs) for blocking or auditing. - Configure web content filtering and threat indicators. 2. **Microsoft Intune:** - Use **Security Baselines** or **Configuration Profiles** to enable Network Protection for specific user/device groups. - Configuration includes options for audit mode, block mode, and custom alerts. 3. **Group Policy:** - Navigate through Windows Components > Microsoft Defender to enable or configure NP. 4. **PowerShell Commands:** - Enable NP: `Set-MPPreference -EnableNetworkProtection Enabled` - Set to Audit Mode: Replace "Enabled" with "AuditMode." 5. **Registry Editor:** - Check or set the NP status under relevant Windows Defender registry paths. 6. **Configuration Manager:** - Configure Network Protection through the endpoint protection settings. --- ### **Testing Network Protection:** - Use Microsoft’s test domain ([smart screen test ratings](www.smartscreentest2.net)) to verify functionality. Enabled NP blocks access to the test page. --- ### **Use Cases and Benefits:** - Prevent phishing scams, malware downloads, and data breaches. - Control access to unsanctioned apps or websites. - Enhance organizational security by detecting and mitigating advanced threats. --- ### **Steps to Enable Network Protection:** 1. Access **Intune Admin Center** or the relevant management tool. 2. Configure policies to include NP in **block mode** for full functionality. 3. Test using a fake domain to verify the setup. 4. Monitor and adjust settings based on organizational needs. --- The video concludes with a request for feedback and suggestions for future topics. Viewers are encouraged to explore the features for better endpoint security and share their learning experience.

Method 2 (using Intune) is an alternative to methods 3 (Group Policy), 4 (PowerShell Commands), 5 (Registry Editor), and 6 (Configuration Manager) because all these methods allow you to enable and configure Network Protection (NP) in different ways. However, method 1 (Microsoft Defender Portal) is focused on managing custom indicators (like adding specific IPs, URLs, or domains for blocking/auditing) and configuring web content filtering, which are different functionalities. These cannot be fully replaced by Intune or the other methods mentioned. Thus: Intune (Method 2): Alternative to methods 3, 4, 5, and 6. Microsoft Defender Portal (Method 1): Complementary to other methods, not replaced by Intune.
