Websites & Domains > IIS Settings.
Common Settings
Directory browsing - Allows the server to generate the list of files in a directory when default index file is absent.
Default Documents - Specifies what file name will serve as a directory index page. It also specifies priority of the file name when more than one matching file name exists.
Mime Types - Add a MIME type for files with a certain extension
Deny access to the site - These settings allow site owners to restrict access to the site by IP address of the visitor by denying and allowing access from certain IP addresses.
Directory Security Settings
Require SSL/TLS - Force all clients (such as browsers or FTP clients) to use the secure HTTPS protocol to access their site (Require SSL/TLS). You need this option, for example, if the site contains and transmits personal information.
You can also Deny IP addresses based on the number of concurrent requests from a unique IP address using IIS dynamic IP restriction
