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 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 links may help:
• If you don't have Active Directory - http://www.isaserver.org/img/upl/vpnkitbeta2/installstandaloneca.htm
• If you have Active Directory - http://www.isaserver.org/img/upl/vpnkitbeta2/installenterpriseca.htm
  
  
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 is recommended.

IIS Configuration

Binding

Add an https site binding

1. Select the Website that contains the web application (ex: Sites/Default Web Site)
2. In the Actions pane, click Bindings... 
3. In the Site Bindings dialog click Add...
4. Add https Binding
1. Type: https:
2. IP Address: All Unassigned
3. Port: 443
4. SSL certificate: Select the certification you installed
5. Click OK
5. Click Close

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
2. Require SSL must not be checked for either Default Web Site or for any application (ex: AdamsAdmin, AdamsWeb, AdamsBridge, etc) under that.  You can check the SSL Settings for each to see that it isn’t.
3. Create the URL rewrite rules for the Default Web Site
1. In IIS Manager select the Default Web Site
2. In the IIS section, open the URL Rewrite module
   
   NOTE: If the URL Rewrite module does not appear as an option after installing it, try closing and reopening IIS Manager.
   
   
3. Click Add Rule(s)…
4. Select Inbound rules > Blank rule
5. Select OK
6. Fill in the following information
   1. Name - HTTP to HTTPS Redirect
   2. Match URL
      1. Requested URL - Matches the Pattern
      2. Using - Regular Expressions
      3. Pattern - (.*)
      4. Ignore case - checked
   3. Conditions
      1. Logical grouping: Match All
      2. Click Add…
         1. Condition input - {HTTPS}
         2. Check if input string - Matches the Pattern
         3. Pattern - ^OFF$
         4. Ignore case - checked
         5. Click OK
   4. Action
      1. Action type: Redirect
      2. Redirect URL: https://{HTTP_HOST}{REQUEST_URI}
      3. Append query string: un-checked
      4. Redirect type: Permanent (301)
7. Click Apply (in the upper hand corner)
8. Click Back to Rules
9. Restart the web application pool

Require SSL/TLS

Require SSL/TLS/HTTPS for all apps.

1. IIS Manager
2. Select Default Web Site
3. Double click on IIS > SSL Settings
4. Check the "Require SSL" box
5. Leave Client certificates set to Ignore
6. Select Apply in the Actions pane
7. Click to select the Default Web Site
8. Click Restart

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.
