Dear KNIME Experts,
we use Microsoft Windows Applocker for “Application Allow Listing”:
AppLocker - Windows Security | Microsoft Learn
…since it is the Top2 NSA recommended security measures against Ransomware:
#StopRansomware Guide | CISA
KNIME does not come applocker compliant out of the box since it extracts at least 3 DLL files to users Appdata directory where they get blocked.
We tackled 2 of them successfully on our own by copying them to KNIME installation directory: localfile_1_0_0.dll + SNAPPYJAVA.DLL
Copied to %programfiles%\knime\
The last one we don’t get fixed since KNIME extracts the same jna.dll evertime new on startup:
C:\USERS\user\APPDATA\LOCAL\TEMP\JNA-<random_number>\JNA<random_number>.DLL
We know this extact problem from other “Eclipse Applications” like KNIME
java - Windows AppLocker Path Wildcards for Files and Folders - Stack Overflow
…but the measures we know do not work here since KNIMEs integrated java runtime does not honor the following settings: Overview (JNA API) (java-native-access.github.io) Loading from the system may be disabled by jna.nosys=true , and unpacking from the jar file may be disabled by jna.nounpack=true
Could you please help us to disable this “extracting and loading DLL from users directory” behaviour and get KNIME Applocker ready?
Any help appreciated 
Best regards
