An IIS 8.5 web server must maintain the confidentiality of controlled information during transmission through the use of an approved TLS version.
Overview
| Finding ID | Version | Rule ID | IA Controls | Severity |

| Description |
|---|
| 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. |
