Transport Layer Security (TLS) encryption is a required security setting for a private web server. Encryption of private information is essential to ensuring data confidentiality. If private information is not encrypted, it can be intercepted and easily read by an unauthorized party. A private web server must use a FIPS 140-2-approved TLS version, and all non-FIPS-approved SSL versions must be disabled.

NIST SP 800-52 specifies the preferred configurations for government systems.


Note: If the server being reviewed is a public IIS 10.0 web server, this is Not Applicable.

Follow the procedures below for each site hosted on the IIS 10.0 web server:

Open the IIS 10.0 Manager.

Click the site name.

Double-click the 'SSL Settings' icon.

Select 'Require SSL' check box.

Select 'Apply' from the 'Actions' pane.
