Is FTP Mac connection secure or not
By itself, the technology of file transfer over the Internet (FTP) is quite vulnerable and does not provide complete security (the protocol was initially unprotected, and it was assumed that the data transmission channel is always reliable). Now, by default, it is assumed that each channel is unreliable and that the data needs to be further encrypted. Unfortunately, FTP, itself, does not support this feature.
A hacker can intercept certain data by connecting to your connection and for this, they do not need to know either a username or a password. There is also the issue of login security: by default, the FTP protocol has no protection against password guessing and login attempts, so someone can simply iterate over the available passwords to gain access to folders.
How to improve FTP connection functions via macOS FTP clients
For all the convenience of using Finder as a Mac OS X FTP client, it is worth noting the ability to access the server in read-only mode. In other words, files can be downloaded from a server to a computer, but not vice versa. If you still need to host something on the server, you will have to use third-party products.
Using FTP on Mac via Terminal opens up a bit more functionality, however, it is not so convenient to use it and not all users feel confident when dealing with Terminal. Some of them are dashed with terror only by the word itself not mentioning the fact that they need to execute certain commands. To set FTP server Mac users can also use different browsers, but again, the functionality is limited and it is not so practical. That is why Mac users are in search for third-parties apps with a wide range of functionality to fully satisfy all their needs.
