We have a requirement from our security team to have Splunk support HSTS feature. Can this be done?
I have seen configuration for other servers like Apache 2 at https://raymii.org/s/tutorials/HTTP_Strict_Transport_Security_for_Apache_NGINX_and_Lighttpd.html
How can we configure Splunk server to support it?
Please let me know.
If you want to add custom headers to Splunk, your best bet is probably to front-end Splunk with Apache or Nginx. Also note that if you enable SSL on Splunkweb, there is no non-ssl port.
In case anyone else is wondering the answer to this question, there is now a way to do this deployment-wide as of version 4.*
Set the following flag globally in $SPLUNKHOME/etc/system/local/web.conf (under [settings] stanza) and in $SPLUNKHOME/etc/system/local/server.conf (in [default] stanza):
sendStrictTransportSecurityHeader = true
