Information
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 If a web server uses weak or outdated encryption algorithms, the server's communications could be compromised.
The U.S. 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.

Solution
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'
Restart the service with the following command:
# vmon-cli --restart applmgmt
