hi, "the Security issues involved with using WebRTC" is fairly generic - what are you referring to?

more options

WebRTC Leaks public/private ip addresses! Please see this link:

https://restoreprivacy.com/webrtc-leaks/

more options

this is less a security vulnerability but a privacy shortfall in the webrtc spec that browsers have to follow to be standard-compliant.

i don't know any details if there were any recent other developments in this area, but firefox allows for extensions to prevent IP address leakage and also provides multiple prefs to modify this behaviour: https://wiki.mozilla.org/Media/WebRTC/Privacy#Prefs_that_control_ICE_Candidate_generation

That is not really a security issue, but merely a privacy issue that your real IP can be exposed that you can encounter if you use a VPN.

You can possibly look at this extension:

I am newly acquiring information on this subject: so, if I may throw out some ideas on what I plan to do and and then you might suggest what measures I might take to avoid any "privacy", or "security" issues. OK? I am a 65 year old with some knowledge of Linux and I have built computers (Desktops mostly) for awhile. I have MX-Linux-18.3 installed on my hardware at this point; with the intention of moving to XCP-ng; a tier-1 Hypervisor. I want to run multiple VM's and have a Web Server on one or more of the VM's to facilitate a local web server and possibly a Jitsi Server on another. I think I understand about using these tools (browser-extentions) while using a VPN; but, what if I am not using a VPN? What if I am "hosting" the Jitsi server locally? From the information that I have read so far, if I use a "hosted" (read Internet Jitsi Host Provider), some of those providers provide additional protections against this type of "privacy/security" issues. Do you have this same knowledge? What if I use a "hosted" Jitsi server? would that be any safer for any clients that I might generate?

https://distrowatch.com/table.php?distribution=whonix . Virtual machines keep the physical computer from malware. This operating system depends on a virtual machine, and can prevent WebRTC leaks.
