The vCenter VAMI service must implement HTTP Strict Transport Security (HSTS).
Overview
| Finding ID | Version | Rule ID | IA Controls | Severity |

| Description | ||||
| HSTS instructs web browsers to only use secure connections for all future requests when communicating with a website. Doing so helps prevent SSL protocol attacks, SSL stripping, cookie hijacking, and other attempts to circumvent SSL protection. | ||||

At the command prompt, run the following command:
# /opt/vmware/cap_lighttpd/sbin/lighttpd -p -f /var/lib/vmware/cap-lighttpd/lighttpd.conf 2>/dev/null|awk '/setenv\.add-response-header/,/\)/'|sed -e 's/^[ ]*//'|grep "Strict-Transport-Security"
Example result:
"Strict-Transport-Security" => "max-age=31536000; includeSubDomains; preload"
If the response header "Strict-Transport-Security" is missing or not configured to "max-age=31536000; includeSubDomains; preload", 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:

Fix Text (F-62806r1003729_fix)
Navigate to and open:
/opt/vmware/etc/lighttpd/applmgmt-lighttpd.conf
If header "Strict-Transport-Security" is not present, add the following line to the end of the file:
setenv.add-response-header += ("Strict-Transport-Security" => "max-age=31536000; includeSubDomains; preload")
If header "Strict-Transport-Security" is present and not set to "Deny", update the value as shown below:
"Strict-Transport-Security" => "max-age=31536000; includeSubDomains; preload",
Note: The last line in the parameter does not need a trailing comma if part of a multi-line configuration.
Restart the service with the following command:
# systemctl restart cap-lighttpd
