Discussion

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.

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|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:

Fix Text

Navigate to and open:

/etc/applmgmt/appliance/lighttpd.conf

Locate the "setenv.add-response-header" parameter and add or update the following value:

"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
