Splunk web to work on https

[LogUx]

Hello Splunkers!!

I want to work Splunk on https. I am using windows server.

How to generate certificate in Splunk and Trustore in some easy steps available?

I followed below document but not giving any good results.

Hi @LogUx,

this is the procedure to generate a certificate or to add an external certificate, but you have also to enable the https on web and you can do it in [Settings > Server Settings > general Settings].

If you want to use a self signed certificate, you don't need to create a new one because Splunk uses its own certificate for the internal management communications; you need only to enable https connection as I described.

@gcusello I did it already but the connection not secure. I want to make connection secure as well.

Hi @LogUx ,

The connection is using a self signed certificate.

So, if the website doesn’t have a thir party certificate, the “HTTPS Not Secure” Message in Chrome will appear, even if you have a certificate.

You can solve the issue using a third party certificate or enabling your browser to recognize this certificate as well.

@gcusello I have used below commands to generate various certificates and adjust web.conf also. But still the connection is not secure.

D:\Splunk\bin\splunk" cmd openssl genrsa -aes256 -out mySplunkWebPrivateKey.key 2048

"D:\Splunk\bin\splunk" cmd openssl rsa -in mySplunkWebPrivateKey.key -out mySplunkWebPrivateKey.key

"D:\Splunk\bin\splunk" cmd openssl rsa -in mySplunkWebPrivateKey.key -text

"D:\Splunk\bin\splunk" cmd openssl req -new -key mySplunkWebPrivateKey.key -out mySplunkWebCert.csr

"D:\Splunk\bin\splunk" cmd openssl x509 -req -in mySplunkWebCert.csr -CA myCACertificate.pem -CAkey myCAPrivateKey.key -CAcreateserial -out mySplunkWebCert.pem -days 1095

"D:\Splunk\bin\splunk" cmd openssl x509 -req -in mySplunkWebCert.csr -CA myCACertificate.pem -CAkey myCAPrivateKey.key -CAcreateserial -out mySplunkWebCert.pem -days 1095

type mySplunkWebCert.pem myCACertificate.pem > mySplunkWebCertificate.pem

web.conf

[settings]
enableSplunkWebSSL = true
privKeyPath = /opt/splunk/etc/auth/mycerts/mySplunkWebPrivateKey.key 
serverCert = /opt/splunk/etc/auth/mycerts/mySplunkWebCertificate.pem
