Ensure 'TLS 1.2' or greater is set for HTTPS access

高レベル 1自動cisco-asa

説明

Enable SSL server version to TLS 1.2. Given that the network may be prone to sniffing, the HTTP access to the security appliance must be secured with SSL or TLS protocols. The latest version of SSL that is SSL v3 is now inclined to many vulnerabilities and systems should use at least TLS 1.2 as ... Matches the PDF's audit: 'ssl cipher tlsv1.2 ...' (9.x) or 'ssl encryption aes256-sha1' (8.x); 'ssl server-version tlsv1.2' is also accepted. Audited against the output of 'show running-config' (run 'terminal pager 0' first; 'more system:running-config' also works and shows unmasked secrets).
