Windows 10: New Tamper protection in Microsoft Defender ATP for Windows 10

Brink · Mar 27, 2019

We are committed to making our solutions resistant to attacks and continuously working towards raising the bar in security. In this blog we’re covering a key feature of our tampering protection strategies, which build on our previously announced Windows Defender Antivirus sandboxing capability.

Tamper protection is a new setting available in the Windows Security app which provides additional protections against changes to key security features, including limiting changes that are not made directly through the app.

If you are a home user, you can toggle the setting from the Virus & threat protection settings area in the app. For enterprise environments, the setting can be managed centrally through the Intune management portal.

We’re continuing to work on the feature, but the current version of the setting is available to Windows Insiders today. The full functionality of the feature (including support for enterprise-level management) will be released along with the upcoming release of Windows 10.

Enabling this feature prevents others (including malicious apps) from changing important protection features such as:

Real-time protection, which is the core antimalware scanning feature of Microsoft Defender ATP next gen protection and should rarely, if ever, be disabled

Cloud-delivered protection, which uses our cloud-based detection and prevention services to block never-before seen malware within seconds

IOAV, which handles the detection of suspicious files from the Internet

Behavior monitoring, which works with real-time protection to analyze and determine if active processes are behaving in a suspicious or malicious way and blocks them

The feature also prevents the deletion of security intelligence updates and the disabling of the entire antimalware solution.

For Windows home users, the feature will be On by default when Windows is installed. If you are upgrading and Cloud-delivered protection is enabled, then the tampering protection feature will also be turned On.

For enterprise customers (such as those with a Microsoft Defender ATP license), this feature will be opt-in and can only be managed from the Intune management console. Local device admin users will not be able to change the setting. This ensures that even malicious apps – or malicious actors – can’t locally override the setting. Note that enterprise management is not available in current preview versions of Windows 10, but we’ll be bringing it to preview shortly.

Now in limited preview

We’re continuing to work on this feature, and you can test it out now on any recent Windows Insider build released during March 2019 or later. If you’d like to test this feature, please send us feedback via the Feedback Hub, or email us at L: wdcustomer@microsoft.com.

We’d love to have you on the journey so we can use your feedback and insights to deliver strong protection across platforms.

Windows Defender ATP.

Why isn't the Windows Defender ATP platform available with Windows 10 Pro for free? What's the difference between Windows Defender and Windows Defender ATP? If you're going to make Windows 10 the best operating system ever, the virus and malware protection
has to be the best too. So having one Windows Defender ATP across the whole Windows 10 ecosystem for free is better then having two different virus and malware platforms?

Defender ATP

Hi,

Thank you for writing to Microsoft Community Forums.

Usually we do not suggest to disable Windows Defender feature, Windows Defender ATP protects endpoints from cyber threats; detects advanced attacks and data breaches, automates security incidents, and improves security posture. However, if you
still wish to disable it, please follow the steps mentioned below and check if it helps:

Open Windows Settings (Windows key + I).

Then click on Updates & Settings.

Then click on Windows Security.

You can disable Cloud based and automatic submissions.

If you need any additional assistance, then please write back with the following information:

What is the exact error message which you are getting?

Is the issue specific to an application?

Could you please
post a screenshot for a better understanding?

Regards,

Windows Defender ATP.

Windows Defender ATP isn't protection, rather it's more after the fact forensics. Any sized firm can run ATP as you can enable it on Windows 10 pro with merely a script. What you have to have is a Windows E5 subscription license which now is sold in single
units by cloud service providers.

The naming of "Windows defender ATP" is IMHO a bad marketing name. It doesn't defend. It reports. It helps an admin understand when intrusions take place what IP the workstation talked to and what may have occurred but it still takes a technical person
to interpret the findings.
