[Icecast] 8000 security risk?

Yes I meant HTTPS over HTTP, which yes, I’m differentiating by those port numbers. Thanks for clarifying! We have been streaming HTTP for a long time, but I am at a university and there is a lot of emphasis on security. I was never really sure what the certificate did for us in this case…but was attempting to comply!

Over the years we have had a small handful of IPs trying to maliciously access our Icecast server over port 8000. I guess the less of that I have to deal with, the better. But if there are streaming aggregators out there who can’t use the HTTPS over the HTTP, then it may be better to deal with the inconvenience once in a while.

Thanks for your help.

Are there any serious security risks for leaving port 8000 open to

radio devices cannot support this protocol.

The port number doesn't matter. I guess in your case you mean HTTP vs HTTPS.

The proper and terse answer is:

It doesn't matter if you use HTTP or HTTPS as long as you have a secure
configuration including managed and strong (not bruteforceable)
passwords AND you keep your Icecast server up to date wrt security
updates (currently Version 2.4.4).

From my anecdotal knowledge gained over 18 years of involvement in
Icecast, if people would follow the above two, then 99,9% of incidents
would not happen.

The longer answer is that it will also depend on your 'threat model' and
how you rate and address things that you consider 'risks' in this frame
of reference. There is no one-fits-all or immediate answer that fits
into this email.

Hope this helps,
