Merge the baselines into one general baseline It will then also white list all executables that the 7-Zip installer puts on your system. Note: Enabling the Intelligent Security Graph option will white list the installer for 7-Zip for instance. Repeat the above process for at least two models, but preferably for each model you have in your environment (or at least the top five mot used models).

We will start with auditing, and eventually in the end of this guide switch to enforced mode. Let’s start with creating a baseline policy from two different machines, which will later be merged to one baseline policy.

Merge the baselines into one general baseline.ġ.Create a baseline on each hardware model.A couple of hours of your time to get going!.

2 physical machines, different hardware models, that run Windows 10 version 1903 or preferably 1909 or later as that gives you some better insights.

So to get started in something that looks like a real world scebario you need this: What is good is that MDAC comes with a use writable protection. As always, this is a balance between security and useability and administration so bear in mind and use this with caution. You can use path rules as of Windows 10 version 1903. You can have multiple policies complementing each other so that you do not have to sign everything nor have to create an entirely new baseline each time you want to allow new things to run. The reason for this it being rather easy to manage now is primarily: This takes application whitelisting to a new level and with Windows 10 version 1903 it becomes the first time since Windows 10 launched that it is actually usuable in many common day scenarios as the administration can now be on a level which is really to manage. What is superior to AppLocker is Microsoft Defender Application Guard (MDAC).

One of them being using regsvr32 to download and execute script directly from the internet for instance. As many security specialists have shown, there are numerous ways to bypass AppLocker and still get code to execute.

Most customers that did not use AppLocker before Wannacry and other types of ransomware attacks are now using AppLocker to prevent malicious software to run on their Windows devices. This is a guide to get you started within an hour or two with what I call “AppLocker Deluxe” and that is Microsoft Defender Application Control, formerly known as Device Guard and up until recently Windows Defender Application Control ( WDAC). Forget AppLocker and all its weaknesses and start using Microsoft Defender Application Control for superior application whitelisting in Windand later.
