SSL Certificate on AWS Application Load Balancer: how to resolve the SSL Self Signed Cert Vulnerability for port 8089?


Hi Team,

We are using Splunk in AWS EC2 Instance. The SSL Certificate is uploaded on the AWS Application Load Balancer. With that, how can we resolve the SSL Self Signed Cert Vulnerability for port 8089? Any insights?

I already had added the confs below, but still the vulnerability was still there.


sslVersions = *,-ssl3
enableSplunkWebSSL = true
cipherSuite = TLSv1.2:!aNULL


sslVersions = *,-ssl3

Hi @jaracan
Although you have set a cert on the ALB, you will by default still be using the default certs on the running Splunk instances.

See this excellent presentation from .conf15 about how to issue your own certs for your entire Splunk deployment.

If my comment helps, please give it a thumbs up!


Could you upload the presentation here, it seems to be expired 

this is probably from previous year
There are some other interesting documents too on this site.
