IISW-SV-000154 - A web server must maintain the confidentiality of controlled information during transmission through the use of an approved TLS version.

Information

Transport Layer Security (TLS) is a required transmission protocol for a web server hosting controlled information. The use of TLS provides confidentiality of data in transit between the web server and client. FIPS 140-2-approved TLS versions must be enabled and non-FIPS-approved SSL versions must be disabled.

NIST SP 800-52 defines the approved TLS versions for government applications.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

Configure the web server to use an approved TLS version according to NIST SP 800-52 and to disable all non-approved versions.
