You can remove TLS 1.0 and TLS 1.1 from DualShield provided you have at least Java version 1.7* installed, by editing the file “Server.xml” that can be found in C:\Program Files\Deepnet DualShield\tomcat\conf (or via the path of your instalation directory)
Before you update the file we suggest you MAKE A BACKUP COPY (in case of any mistakes that may need you to revert back to this copy).
The file is in the sub-folder “\tomcat\conf”, and to make remove TLS 1.0 and TLS 1.1 you will need to first search for all instances of "SSLEnabledProtocols=";
For each instance you find, you will need to remove "TLSv1, TLSv1.1", e.g.;
Again ensure the original “Server.xml” file has been backed up, update the changes made above, then restart the DualShield service, and you should now be PCI-DSS compliant.
You can identify which version of Java is running on your DualShield Authentication Server by opening a command prompt, navigating to the sub-folder "\jre\bin" of the DualShield installation directory, then typing "java -version";
