A few RFCs have extended its functionality over the years, such as RFCs 354 and 765. The original FTP protocol was standardized through a few RFCs starting with RFC 114. Over the years, it has been modified to support encryption and information security through various updates. You may see it in entry-level cybersecurity training, like Security+, but also day-to-day in just about any networking role. Making Secure Purchases over the Internetįile Transfer Protocol (FTP) is one of the oldest protocols. SSL) is what makes HTTP secure - thus Hypertext Transfer Protocol Secure (HTTPS). Currently known as Transport Layer Security (TLS), this cryptographic protocol is vital to communications security. It also protects data sent between two systems. Secure Sockets Layer (SSL) is the standard technology that keeps an internet connection secure. Over time it has been extended and used for other purposes such as transferring files. HTTP is typically used to transfer documents such as HTML primarily for web browsers. Hypertext Transfer Protocol (HTTP) is a transfer protocol you'll see from the moment you start learning networking basics. Cybersecurity professionals need to understand how secure all transfer protocols are, even if they're just getting started in security. If you cannot rely on delivering the exact same data from one place to another, it is not very useful. Transfer protocols also need to be reliable for their use case. FTP has always been good with this, although certain flavors such as SFTP have options for compression that can sometimes help. Having a robust data transfer protocol in place will also help prevent malware and other threats.Īs data files become larger, the speed and efficiency of transferring the data are important. Today, people are copying confidential information, health records, and other sensitive information that they want to have encrypted.
