Configure TLS 1.2 (Transport Layer Security)

Configure TLS 1.2 (Transport Layer Security)

In line with industry security recommendations the erwin CW products now support Transport Layer Security version 1.2. This security layer is a low level network encryption protocol which can optionally be used between applications and MS SQL Server. Many large organizations have been disabling TLS1.0 and TLS1.1 in favor of the newer TLS1.2, as it has certain improvements that make it less susceptable to security vulnerabilities.

In order to configure erwin EA/BP for TLS1.2 there are some steps required that go beyond a simple install. This document will guide you through these steps.

          1. Run the following Microsoft Installer “sqlncli.msi” which can be obtained from here
                    https://www.microsoft.com/en-us/download/details.aspx?id=50402

                   
                    for either x64 (64bit) or x86 (32bit) - as is approriate to your environment.

          2. Set the following Entries in the registry. These can be copied into a file that is given the extension .reg and then run in windows, or downloaded with your erwin                     software.
                    Most of the entries are to disable TLS 1.0 and TLS1.1, then enable TLS1.2. The final entry is to configure erwin EA/BP to use the correct SQL Server client.

After changing the registry settings, it may be necessary to reboot your machine.

          3. Once this has completed, start "erwin EA/BP Modeler" and when the logon dialog appears click the “Edit” button.
                    This will display all the available connections.

          4. Click on the connection you want to use and "Edit" it.

          5. Next to the server name there will be a check box to enable the use of TLS1.2.
                    Check this box and press "OK" to close the dialogs.

          6. Having made these changes the erwin EA/BP applications should run as normal.

Troubleshooting:
On some operating systems this additional msi file may also be required to get the application to run successfully

Run the following Microsoft Installer “msoledbsql_18.1.0.0_x64.msi” which can be obtained from here

Enabling and using the REST API

Evolve REST API (2018.1.0.79 and above)

The Evolve REST API was added to provide backwards compatibility support for the discontinued Web Portal SOAP API.

Where it differs slightly is in the method of calling the API. This has been modified to use the more standard RESTful http approach, using
POST, GET, PUT and DELETE protocols.

All of the calls return a json response, but can optionally return XML. The XML returned is equivalent to the older Portal API, and so should
ensure it is relatively simple to integrate, in-place of the older service.

To configure the API, it is first necessary to enable it from within Evolve:

          1. Having configured and ensured the Evolve server is functioning.
          Start Evolve Designer with Administrator Permissions.

          2. Goto your Evolve server settings

          3. Check the box 'Enable Web REST API"

          4. Save the configuration

          5. Press "Configure IIS"

The default endpoint for the API will be:

http://<your-server>/WebRESTAPI/api/<path to endpoint>

To use the REST API, please see the documentation, located here.

When using the API, always remember to use the /auth endpoint to authenticate first, and remember to include the returned token
in all subsequent calls to the API. This token should be encoded in the header of the http request.
