The web server must remove all export ciphers to protect the confidentiality and integrity of transmitted information.

| Description | ||||
| During the initial setup of a Transport Layer Security (TLS) connection to the web server, the client sends a list of supported cipher suites in order of preference. The web server will reply with the cipher suite it will use for communication from the client list. If an attacker can intercept the submission of cipher suites to the web server and place, as the preferred cipher suite, a weak export suite, the encryption used for the session becomes easy for the attacker to break, often within minutes to hours. | ||||

Details
Check Text (C-206440r961632_chk)
Review the web server documentation and deployed configuration to determine if export ciphers are removed.
If the web server does not have the export ciphers removed, this is a finding.
Fix Text (F-6701r377913_fix)
Configure the web server to have export ciphers removed.
