Secure Communications

The Secure Communications page of the Configure Web Synchronization Wizard configures Secure Sockets Layer (SSL) settings for encrypted communication.

Note

The Secure Communications page is not displayed if you are configuring the virtual directory for SQL Server Subscribers. SQL Server Subscribers require SSL connections.

Using SSL

When a Web browser supporting secure communications connects to a Web site configured to use SSL (URLs starting with https://), a secure connection protects the data that is being transferred. A client certificate is a digital identification issued by a trusted, third-party organization, referred to as a certification authority. You can configure your Web server to accept, require, or reject client certificates as a way of establishing a connection with a particular file or directory. Users trying to access a site with client certificates can be mapped. Users without client certificates can use other authentication methods. Client certificate mappings match information that is contained in a client's certificate against Windows user account information. A certificate trust list (CTL) is a list of approved certification authorities for a particular Web site. For more information, see Configuring SSL Encryption.

Do Not Require Secure Channel (SSL)

Select this option if you do not require the users to go through the SSL channel.

Require Secure Channel (SSL)

Select this option to configure IIS to require an encrypted communication link for a Web browser to connect. When this option is selected, all data sent to and from this Web site is encrypted using a certificate and users will use the URL https://.

Important

You must create a new certificate or attach to an existing certificate before you select this option.

Require Client Certificates

Select this check box to permit only users with a valid client certificate to connect. Users without a valid client certificate are denied access to this site.
