Certificate

A certificate, signed by a certificate authority needs to be created and installed on the web server. How this is done differs if the server is accessible from the public internet or not.

Public Facing Web Server

If the web server is public facing then a free certificate can be obtained using Let's Encrypt. follow Follow the instructions in SSL/TLS using Let's Encrypt

Alternatively you can use any commercial certificate authority. Ex: DigiCert, Entrust, Thawte, etc.

Internal Web Server

If the server is internal then an internal Certificate Authority will be needed.

1. Identify the Certificate Authority (CA) - If you need to setup Microsoft Certificate Services the following

   • Install the Certificate Authority

2. Install the Certificate - Request and install a certificate for the website under which the application will run. See: How to Get a Certificate from an internal CA

   • The certificate must be created for a website (ex: Default Web Site) not the virtual directory for the web application.

   • A Bit length of 2048

   • Select SHA256 for your hash algorithm.

   • Set the Subject Alternative Name to the FQDN of the server or a wildcard that includes the server (ex: *.mydomain.gov)

   • Validity period of 389 days or less

   • ExtendedKeyUsage extension containing the id-kp-serverAuth OID

URL Rewrite

HTTP Redirect to HTTPS

Use the URL Rewrite module to change incoming HTTP URLs to be HTTPS.

1. Install the URL Rewrite Module for IIS: http://www.iis.net/downloads/microsoft/url-rewrite (scroll to bottom for installers by language and architecture)

2. Require SSL

1. Condition input: {HTTPS}
2. Check if input string: Matches the Pattern
3. Pattern: ^OFF$
4. Ignore case: checked
5. Click OK

...

2. IIS Manager must be closed

3. Add a web.config file to the web server's root directory (ex: c:\inetpub\wwwroot) with the below content or the configuration section only if the web.config already exists.  The web server's root directory is typically c:\inetpub\wwwroot even if you have installed Adams web applications on another drive such as e:\inetpub\wwwroot.
   
   

   web.config

   Code Block
   language xml
   <?xml version="1.0" encoding="UTF-8"?> <configuration> <system.webServer> <rewrite> <rules> <rule name="HTTP to HTTPS redirect" stopProcessing="true"> <match url="(.*)" /> <conditions> <add input="{HTTPS}" pattern="off" ignoreCase="true" /> </conditions> <action type="Redirect" url="https://{HTTP_HOST}/

Service Endpoints (Pre-ADAMS 6.1)

Make it so that web services can or must use HTTPS.

Edit service endpoints in web.config files for Adams Admin and Adams Web

1. Open web.config

2. Find <services>

3. For each endpoint within each <service> do one of:

   1. For HTTPS access only: Edit “Http” in binding value to “Https”.
      
      Ex: “basicHttpBinding” ➔ “basicHttpsBinding”; “mexHttpBinding” ➔ “mexHttpsBinding”
      

   2. For both HTTP and HTTPS access: Add a copy all endpoints with “Http” in binding value and edit value to have Https.
      
      Ex: Copy endpoint line and edit “basicHttpBinding” ➔ “basicHttpsBinding” – Use this if both HTTP and HTTPS will be used.
