InformationTransport Layer Security (TLS) provides protection when communicating over the internet. Traffic is encrypted for portions of information transportation. Ensure that the Central Administration site is configured to be used with TLS.
The SharePoint Central Administration site allows an administrator to manage settings for the Web server and virtual servers. TLS protects this critical data by encrypting the traffic that is transmitted over the network.
SolutionAn SSL certificate must be acquired before enabling TLS. For more information about SSL certificates, see related topics in IIS Help.
The Central Administration site must also be first configured to use port 443 and HTTPS. To configure this, execute the following Windows PowerShell command:
Set-SPCentralAdministration -Port <port> -SecureSocketsLayer
NOTE: If the server certificate is for an FQDN update the AAM URL of the Central Administration web site:
Set-SPAlternateUrl -Identity https://servername:443 -Url https://fully.qualified.domain.name:443 -Zone Default
Navigate to Internet Information Services (IIS) Manager.
