Encrypting data in flight across the Internet protects you by preventing outsiders on the big-bad-internet from seeing the contents of your communications. Encryption protects you against individuals inside your network by preventing them from seeing application traffic (and potentially account passwords) in the clear.Encrypting infrastructure protocols in flight turns out to provide a very poor tradeoff. Microsoft shipped version 3 of its SMB protocol in 2012, which provided the option to encrypt SMB traffic. With encrypted SMB v3 deployed, encryption could allow one to attack neighboring systems with no possibility of oversight.”]
