Ensure 'forms authentication' require SSL

SedangLevel 1Otomatisiis

Deskripsi

Forms-based authentication can pass credentials across the network in clear text. It is therefore imperative that the traffic between client and server be encrypted using SSL, especially in cases where the site is publicly accessible. It is recommended that communications with any portion of a site using Forms Authentication be encrypted using SSL. Wherever forms authentication is the mode (root web.config and each site), forms requireSSL must be true. Compliant when forms authentication is not used. PowerShell 5.1 with the WebAdministration module; run elevated.
