At the command prompt, run the following command:
# /opt/vmware/sbin/vami-lighttpd -p -f /opt/vmware/etc/lighttpd/lighttpd.conf 2>/dev/null|awk '/setenv\.add-response-header/,/\)/'|sed -e 's/^[ ]*//'|grep "Strict-Transport-Security"
Expected result:
"Strict-Transport-Security" => "max-age=31536000; includeSubDomains; preload",
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:

"Strict-Transport-Security" => "max-age=31536000; includeSubDomains; preload",
Note: The last line in the parameter does not need a trailing comma.
Restart the service with the following command:
# vmon-cli --restart applmgmt
