VAMI must be configured with FIPS 140-2 compliant ciphers for HTTPS connections. (Cat I impact)
Encryption of data in flight is an essential element of protecting information confidentiality. If a web server uses weak or outdated encryption algorithms, the server's communications can potentially be compromised. The US Federal Information Processing Standards (FIPS) publication 140-2, Security Requirements for Cryptographic Modules (FIPS 140-2), identifies 11 areas for a cryptographic module used inside a security system that protects information. FIPS 140-2 approved ciphers provide the maximum level of encryption possible for a private web server. VAMI is compiled to use VMware's FIPS-validated OpenSSL module and cannot be configured otherwise. Ciphers may still be specified in order of preference, but no non-FIPS-approved ciphers will be implemented. Satisfies: SRG-APP-000014-WSR-000006, SRG-APP-000179-WSR-000111, SRG-APP-000416-WSR-000118, SRG-APP-000439-WSR-000188
At the command prompt, execute the following command: # /opt/vmware/sbin/vami-lighttpd -p -f /opt/vmware/etc/lighttpd/lighttpd.conf|grep "ssl.cipher-list" Expected result: ssl.cipher-list = "!aNULL:kECDH+AESGCM:ECDH+AESGCM:RSA+AESGCM:kECDH+AES:ECDH+AES:RSA+AES" If the output does not match the expected result, this is a finding.
Navigate to and open /etc/applmgmt/appliance/lighttpd.conf. Add or reconfigure the following value: ssl.cipher-list = "!aNULL:kECDH+AESGCM:ECDH+AESGCM:RSA+AESGCM:kECDH+AES:ECDH+AES:RSA+AES"
The information system implements cryptographic mechanisms to protect the confidentiality of remote access sessions.
The information system implements mechanisms for authentication to a cryptographic module that meet the requirements of applicable federal laws, Executive Orders, directives, policies, regulations, standards, and guidance for such authentication.
The information system protects the confidentiality and/or integrity of transmitted information.
