Information moving.
WHEN DATA MOVES
Between you and a website In email When transferring files When backing up to a remote service
WHAT TO USE
Encrypted connections, always.
FOR WEBSITES
HTTPS throughout.
FOR FILE TRANSFER
FTPS or SFTP, never plain FTP.
Plain FTP sends credentials readable.
FOR EMAIL
Encryption between servers is common but not guaranteed.
Treat email as not private for genuinely sensitive material.
WHAT THAT MEANS PRACTICALLY
Do not email documents containing anything you would be alarmed to see disclosed.
WHAT TO USE INSTEAD
A file sharing service with access control An encrypted archive, with the password sent separately
THE SEPARATE CHANNEL POINT
Sending a password in the same email as the file achieves nothing.
WHAT TO CHECK
That every service you use is configured for encryption.
