Discussion

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 If a web server uses weak or outdated encryption algorithms, the server's communications could be compromised.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. Satisfies: SRG-APP-000014-WSR-000006, SRG-APP-000416-WSR-000118, SRG-APP-000439-WSR-000188

Check Content

At the command prompt, run the following command:

# /opt/vmware/sbin/vami-lighttpd -p -f /opt/vmware/etc/lighttpd/lighttpd.conf 2>/dev/null|grep "ssl.cipher-list"|sed -e 's/^[ ]*//'

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.

Note: The command must be run from a bash shell and not from a shell generated by the "appliance shell". Use the "chsh" command to change the shell for the account to "/bin/bash". Refer to KB Article 2100508 for more details:
