Final answer:
To transfer large files over the internet securely, utilize cloud services with encryption, encrypt files prior to transfer, and consider FTPS or SFTP protocols ensuring strong passwords and two-factor authentication are in place.
Step-by-step explanation:
Transferring large files securely over the internet requires the use of services or protocols designed to handle big data sizes while providing encryption. One common method is using a cloud service, which often comes with robust security and the ability to handle large files. Before transferring, it's advisable to encrypt files, ensuring that even if intercepted, the data remains protected.
Additionally, consider using a File Transfer Protocol (FTP) service with Secure Sockets Layer (SSL), known as FTPS, or Secure File Transfer Protocol (SFTP), which uses SSH for secure file transfer. Always ensure that you're using strong passwords and, if possible, enable two-factor authentication for added security.
