Windows Defender Exploit Guard
- Windows 10, version 1709
- Enterprise security administrators
Windows Defender Exploit Guard (Windows Defender EG) is a new set of host intrusion prevention capabilities for Windows 10, allowing you to manage and reduce the attack surface of apps used by your employees.
There are four features in Windows Defender EG:
- Exploit protection can apply exploit mitigation techniques to apps your organization uses, both individually and to all apps
- Attack surface reduction rules can reduce the attack surface of your applications with intelligent rules that stop the vectors used by Office-, script- and mail-based malware
- Network protection extends the malware and social engineering protection offered by Windows Defender SmartScreen in Microsoft Edge to cover network traffic and connectivity on your organization's devices
- Controlled folder access helps protect files in key system folders from changes made by malicious and suspicious apps, including file-encrypting ransomware malware
You can evaluate each feature of Windows Defender EG with the guides at the following link, which provide pre-built PowerShell scripts and testing tools so you can see the features in action:
You can also enable audit mode for the features, which provides you with basic event logs that indicate how the feature would have responded if it had been fully enabled. This can be useful when evaluating the impact of Windows Defender EG and to help determine the impact of the features on your network's security.
You can also visit the Windows Defender Testground website at demo.wd.microsoft.com to confirm the features are working and see how each of them work.
Windows Defender EG can be managed and reported on in the Windows Defender Security Center as part of the Windows Defender Advanced Threat Protection suite of threat mitigation, preventing, protection, and analysis technologies, which also includes:
- The Windows Defender ATP console
- Windows Defender Antivirus in Windows 10
- Windows Defender SmartScreen
- Windows Defender Device Guard
- Windows Defender Application Guard
You can use the Windows Defender ATP console to obtain detailed reporting into events and blocks as part of the usual alert investigation scenarios. You can sign up for a free trial of Windows Defender ATP to see how it works.
Each of the features in Windows Defender EG have slightly different requirements:
|Feature||Windows Defender Antivirus||Windows Defender Advanced Threat Protection license|
|Exploit protection||No requirement||Required for reporting in the Windows Defender ATP console|
|Attack surface reduction||Real-time protection must be enabled||Required for reporting in the Windows Defender ATP console|
|Network protection||Real-time protection must be enabled||Required for reporting in the Windows Defender ATP console|
|Controlled folder access||Real-time protection must be enabled||Required for reporting in the Windows Defender ATP console|
Each feature's requirements are further described in the individual topics in this library.
