How can i put password protection on 8000 port

[montu]

While following the snort 3 manual, after putting the license of splunk on free option, the password protection is gone. Now any computer of my internal and probably external network can log into my 8000 port without any protection. how to put a password protection on this port?

You didn't say whether this is your lab or for your business or what.  Some things you can do:

1.  License Splunk Enterprise and install the Enterprise license.  This gives you support and so on, but is probably out of reach for personal budget.
2. If this is your NONPRODUCTION lab environment and you can abide by the terms of the development license, get a development license.  See https://dev.splunk.com/enterprise/dev_license.
3. Put a reverse proxy like Nginx in front of Splunk's UI.  Move Splunk to 127.0.0.1 on an alternate port.  Make the reverse proxy do authentication.  Note this still leaves you with an extremely limited Splunk Free that does not have scheduling or alerts or all of the other features you'll be missing.  This requires a little sysadmin skill to pull off successfully.

Use a firewall to protect port 8000. You can also buy a Splunk license to restore password-controlled access.

I have no experience with Kali Linux, but a quick Google search of "kali linux firewall" returns several promising results.
