Turn on Mandatory ASLR in Windows Security
I've been using it for quite a while now, it caused no problems or errors with any legitimate programs, games, anti cheat systems etc other than with some "custom" made portable programs. it's Off by default, when you turn it on, you will have to restart your device. Address space layout randomization Address space layout randomization (ASLR) is a computer security technique involved in preventing exploitation of memory corruption vulnerabilities. In order to prevent an attacker from reliably jumping to, for example, a particular exploited function in memory, ASLR randomly arranges the address space positions of key data areas of a process, including the base of the executable and the positions of the stack, heap and libraries. The Linux PaX project first coined the term "ASLR", and published the first design and implementation of ASLR in July 2001 as a patch for the Linux kernel. It is seen as a complete implementation, providing also a patch for kernel stack randomization since October 2002.[1] The first mainstream operating system to support ASLR by default was the OpenBSD version 3.4 in 2003,[2][3] followed by Linux in 2005. https://en.wikipedia.org/wiki/Address_space_layout_randomization https://blogs.technet.microsoft.com/srd/2017/11/21/clarifying-the-behavior-of-mandatory-aslr/ Other options that are tuned off by default and you should enable to make your Windows device more secure With the increasing number of threats in cyber security and new ransomwares, If you are only relying on Windows 10's built in security and not using any 3rd party AV such as Kaspersky, you must enable these features to keep yourself secure. Hope everyone stay safe!
Get-MpComputerStatus returns no output
Hello, on a Server 2019 with windows defender installed in the "Windows Security GUI" all is fine. Protection definitions are up to date, exclusions are set ... (managed with SCCM) But when i use the Get-MpComputerStatus it returns no output. (not even an error) Please help.[SOLVED] Memory Integrity bounces back to "turned off" state after Windows restart - fast ring 19536
This is an old post and the issue is no longer relevant. This has been happening since a couple of builds ago as well. I turn on the Memory Integrity in Core isolation section of Windows Defender, then after a restart or two, I go check again and see it's turned off. it usually happens when I uninstall a program that needs to be restarted. but it also happens when I uninstall a software that does Not need Windows restart to finish uninstall process. https://aka.ms/AA6xajf
Windows Defender Application Guard inside Windows Security App
Windows Defender Application Guard is designed to prevent attacks on local machines and from expanding malicious activity throughout a corporate network. If you are interested in learning more about Application Guard and how to install it in standalone mode, please see our previous blog. In the upcoming Windows release (Build 17691+), we have built an interface to configure Windows Defender Application Guard inside the Windows Security app. This allows users to configure Application Guard or check the administrator’s configuration of Application Guard at the same place as other Windows security features. The four settings that can be configured for Application Guard in the Windows Security app are: Save data Copy and paste Print files Advanced graphics Standalone users with devices that meet the minimum requirements will see Application Guard in the Browser & apps control section in Windows Security. From there, users can invoke the installation of this feature and configure its settings. When devices fall below the minimum spec, users will be alerted of this in the configuration page for Application Guard. Managed users can see how their administrators have configured their settings to have a better understanding of how they can operate between an Application Guard container and their host system. Here’s how users can configure or check their Application Guard status: Install and configure Go to the Windows Security app and select “App & browser control.” Select “Install Windows Defender Application Guard” under Isolated Browsing. Check the “Windows Defender Application Guard” box and Install from the Turn Windows features on or off screen and click OK. Restart your device. Return to the Windows Security app and select “App & browser control.” Select “Change Application Guard settings” to configure the settings. View managed Application Guard settings Go to the Windows Security app and select “App & browser control.” Select “Change Application Guard settings” to view the settings. Review the configurations set by your administrator. We encourage Windows Insiders to use the Windows Security app to configure and view Application Guard settings. Your feedback, suggestions, and telemetry will help us to improve Application Guard’s user experience.

This month we’ve released Windows Defender tamper protection management in Microsoft Intune! Tamper protection is a new setting available in the Windows Security app which adds additional protections against change to key Windows Defender security features. Enabling this feature prevents others (including malicious apps) from changing/disabling 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. Enterprise management of this feature via Intune requires an E5 license (such as those with a Microsoft Defender ATP license) and the device be MDM enrolled into Intune. The feature is available on Windows 10 1903 Enterprise devices, and we’re looking at backporting the feature to down level Windows clients later this year. Before you can enable the setting, you need to connect Microsoft Defender ATP to Intune. To do this, browse to https://securitycenter.windows.com and visit Settings > Advanced features. Turn the Microsoft Intune connection on and press save. Next, browse to the Microsoft Intune console. To enable Windows Defender tamper protection, create an Endpoint Protection policy in Intune and enable the Tamper protection feature. Assign this policy to a user or device group, and tamper protection will be enabled. To disable the feature, change the setting to Disabled and deploy the policy to the target devices. Note: Not configured will not change the state of a previously deployed configuration. To disable tamper protection, you must deploy a Disabled policy state.

Problem: If Forticlient 5.6 is installed and configured to have real time scanning disabled, in Windows 1709 defender forces its own real time scan to be disabled. The problem is the Forticlient is used for firewall policy enforcement so we really want to use it. Is there a way, through either Windows Intune or Defender ATP to configure that defender is primary threat protection? Thanks! -Neil
