There are a lot of new and exciting changes included in ThingWorx 8.0.0, which is due out today, and no doubt, you'll want to get a test environment set up to try them out.  But there are a few changes that could impact your ability to get up and running with a new server that I wanted to share with everyone.



IMPORTANT – Changes to Licensing in ThingWorx 8.0.0

 

In ThingWorx 7.4.0, a new Licensing Subsystem was introduced, and the license file required was provided as part of the ThingWorx 7.4.0 platform download.  As of ThingWorx 8.0.0, the license.bin file will no longer be provided with the platform download, but will instead need to be downloaded from the PTC Licensing Tool on the PTC eSupport Portal.

 

As part of the operating system specific Installing ThingWorx (OS) sections in the Installing ThingWorx 8.0 guide, additional steps have been added that outline how to use the PTC Licensing Tool to download and install the ThingWorx license file for your organization.

 

The license file downloaded from the ThingWorx Licensing Tool must be renamed to license.bin and copied to the /ThingworxPlatform directory prior to starting ThingWorx for the first time.  The server will fail to start if it cannot find this license file.

IMPORTANT – Default Administrator Password for ThingWorx Composer is Changing in 8.0.0

 

In order to help encourage the use of secure passwords for the Administrator account on ThingWorx servers, the default Administrator account password will be changing in version 8.0 and above.  The new Administrator password is a complex password containing mixed case and special characters. This will encourage administrators to change their default, fully-privileged account password to one that is more secure and conforms to their organizational security standards.

 

Information about the new default password can be found in each of the operating system specific Installing ThingWorx (OS) sections of the Installing ThingWorx 8.0 guide.

PTC strongly advises against the use of any default password on any product, and encourages administrators to immediately change any default password to a proper, complex password.

Application Key Usage is Changing in 8.0.0

 

As part of an effort to better secure the ThingWorx Platform, the use of Application Keys as URL parameters (through the ‘appkey’ parameter) is being deprecated in ThingWorx 8.0.0.

 

For example, the following URL uses the now deprecated ‘appkey’ parameter to pass in an application key:

 

              https://thingworx.server.com/ThingWorx/Things/MyThing/Services/MyService?appkey=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

 

When included in the URL, the ‘appkey’ parameter becomes a browser-cacheable, clear-text rendition of a usable application key.  A knowledgeable user could retrieve this application key from their browser history and use it to perform unauthorized actions against a ThingWorx server.

 

For full security, GET and POST requests that are run against a ThingWorx server should be performed over an HTTPS connection and should include the required application key in the request’s headers.  Query string parameters are visible in both HTTP and HTTPS contexts, and by moving the application key into the request headers, the application key itself is encrypted as part of the HTTPS request. (Note that the application key in a header is still visible for plaintext HTTP connections though!)

 

By default, new installations of ThingWorx 8.0.0 will have the Allow Application Key as URL Parameter option disabled.  Upgrades from previous versions of ThingWorx will retain the ability to use the ‘appkey’ query string parameter, but PTC strongly encourages customers to promptly update any solutions that are dependent on sending the appkey using a URL parameter to move to request headers instead.  Please note that a future release of ThingWorx may completely disable the use of application keys as URL parameters.

 

The Allow Application Key as URL Parameter option can be enabled or disabled on the ThingWorx PlatformSubsystem’s configuration page, accessible at System > Subsystems > PlatformSubsystem > Configuration.

Changes to Default Visibility (Organizations) in ThingWorx 8.0.0


Starting in ThingWorx 8.0.0, the Everyone organization will no longer be granted default visibility across all entity collections.  Only users who are a member of the Administrator group will be able to see ThingWorx entities on a newly installed server; any additional visibility permissions will need to be explicitly granted by the Administrator.

 

This is a change in behavior from the previous ThingWorx releases where the Everyone organization (of which the all-encompassing Users group was a member) was granted visibility access by default to all entity collections. Visibility permissions had to explicitly be removed by the Administrator during solution development, which could be overlooked.
