Is Teamviewer a security risk
I have recently learned about TeamViewer, which allows you to remotely connect to another TeamViewed enabled computer, either to retrieve files or operate the "home" computer. Possibly a very convenient thing on occasion.
I do not understand very much about open ports, "listening", and "calling out", but I am surmising that if one calls one's home computer from a distant computer using TeamViewer (perhaps any remote conncection) that the home computer must be listening, and therefore must have an open port.
If I understand it, Ubuntu doesn't normally open ports to "listen" for incoming connections, so if this is what TV is doing, does this represent a significant security risk? And if so can it be mitigated?
I'm old, but still tryin'. Your patience appreciated.
