This mitigation can be done in several ways, In my opinion and based on my experience, this This default setup provided by Microsoft it’s quite normal nowadays that thereĪre some modern workplace implementation where the users are a localĪdministrator on their device. If you don’t want your users to become a localĪdministrator on the device, you need to leverage Windows Autopilot where youĬan define this behavior (whether or not the user gets added to the localĪdministrator group) in a deployment profile. If you do this, by default the account performing the join will be added to the (OOB) experience, you can choose to join the device to Azure Active Directory. Start Windows 10 business editions for the first time in the Out of the Box Current state of local admin rights on Windows 10 devices Simplistic way of enabling Applocker policies, in the real world there are someĬaveats which must be addressed when implementing Applocker. My own tenant, and how I started to use these principles myself whichĮventually led by removing my account from the local administrator group.ĭisclaimer: This blogpost provides a very Sami referred to a quote from Mikko Hyppönen (Chief Research Officer atį-Secure): “ Make your security better than yourīlogpost I will share my experience with implementing Applocker policy within In 2020 and forward”, Sami made us aware that by implementing some simpleĪpplocker policies on our Modern Workplace and by making sure that the userĪdmin rights, we can seriously improve our security. In his presentation titled: “Securing Windows Professionals in the Windows OS and Security flying over to the Netherlands and Windows built-in SRP assumes also, that the system can protect users against fileless exploits - which is partially true in Windows 8 , and even more true in Windows 10.įinally, when the home user needs the enterprise protection, then he/she can go for AppGuard.Management User Group Netherlands meeting, we had the honor to have Sami Laiho, one of the world’s leading But, that is a solution for users that prefer security over usability. I think about introducing such option in Hard_Configurator. This is the solution known in Bouncer, NVT ERP, and other ani-exe porograms. Of course, more security paranoid home user should listen to your advice, and put sponsors (cmd.exe, wscript.exe, cscript.exe, mmc.exe, mshta.exe, powershell.exe, powershell_ise.exe, regedit.exe, and many others) to SRP Black List. In practice, it works exceptionally well, because SRP can also mitigate many exploits. It assumes that the system and software are hard to exploit by malware in the wild (updated Windows 8 ), and no one bothers to make a targeted attack. The LNK solution blocked scripts is appropriate only for home users. This loophole can be made smaller if CMD, WSH, and PowerShell scripts are blocked by the reg tweak." "Yet, whitelisting LNK locations have the side effects, that now I can run all scripts (BAT, CMD, JS, JSE, PS1, VBS, VBE, WSF, HTA), and configuration files (CPL, MSC, REG) in the User Space, by the shortcut in whitelisted location. And, that is the price, that have to be paid in Windows, when one prefers usability over security. I am curious how the LNK problem looks like on other computers.Ĭlick to expand.That's right. This loophole can be made smaller if CMD, WSH, and PowerShell scripts are blocked by the reg tweak.Ībove tweaks works in the same way on my 2 computers - Win 10 Pro (SRP configured by Secpol) and Win 7 Home (configured by reg hack). Yet, whitelisting LNK locations has the side effect, that now I can run all scripts (BAT, CMD, JS, JSE, PS1, VBS, VBE, WSF, HTA), and configuration files (CPL, MSC, REG) in the User Space, by the shortcut in whitelisted location. I simply disallowed LNK files globally, and then whitelisted them in some folders for using 'Power Menu', 'Desktop', and 'Start Menu' shortcuts. %LOCALAPPDATA%\Microsoft\Windows\WinX\Group3\*.lnkĬ:\ProgramData\Microsoft\Windows\Start Menu\*.lnkĬ:\ProgramData\Microsoft\Windows\Start Menu\Programs\*.lnkĬ:\ProgramData\Microsoft\Windows\Start Menu\Programs\*\*.lnk %LOCALAPPDATA%\Microsoft\Windows\WinX\Group2\*.lnk %LOCALAPPDATA%\Microsoft\Windows\WinX\Group1\*.lnk %HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ProgramFilesDir% %HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ProgramFilesDir (x86)% %HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SystemRoot% Here are all path rules in my SRP configuration: I figured out how to minimize LNK execution problem in my setup. Your system is somewhat more restricted than mine for LNK or EXE files.
