So, I joined an artwork site where the user can create a gallery. The problem is, after speaking to the admin (who has to add people manually) is that it's only done by setting up FTP server. I do in a program called FileZilla, well need to back up a bit. I followed this tutorial here https://revision3.com/oneoff/hak5gtae5/ and did so accordingly. But now, I admit that I'm wary, wary that some nut will you know, cause malicious files and or malware to be installed via the FTP, despite the fact that the admin of this site has to add users manually and not just anyone can have one. He set up the username and password, which I told the FTP program not to remember. Should I be wary/paranoid about having the FTP I set up sync at set intervals? Are there things I can do to make sure I reduce the likelihood of being compromised?
