On the internet, file sharing is a standard technical function many web hosting servers perform. However, cyber threats have become a significant threat many website owners encounter. To overcome this problem, FTP (File Transfer Protocol) is used. FTP is one of the oldest protocols used in the internet world.
FTP establishes a secure connection between computers on networks that share/upload files and transfer data between servers. MilesWeb’s shared hosting servers leverage this protocol to shield the customer’s data. In this article, we delve deeper to understand different file transfer protocol types used for businesses.
FTP Types: Different Protocols Businesses Use
1. Anonymous FTP
Firstly, the primary FTP type we will discuss is the anonymous FTP, which allows data transfer without encryption or login. This is the commonly used protocol to download material allowed for unrestricted distribution. Port 21 is responsible for its functionality.
Real-life example: Anonymous FTP is often used to distribute software and code in open-source projects.
2. Password-Protected FTP
Like anonymous FTP, the password-protected FTP type requires login credentials, a username, and a password. This protocol is also accessible on port 21 with a limited possibility of insecurity.
Real-life example: Small business organizations share files between their employees and clients using password-protected FTP.
3. FTP Secure Socket Layer (FTP-SSL)
FTP Secure Socket Layer (FTP-SSL) is a secure file transfer protocol that allows businesses to connect securely with their customers, users, and trading partners. It’s an extension of the File Transfer Protocol (FTP) that supports Transport Layer Security (TLS) and Secure Sockets Layer (SSL) cryptographic protocols.
Real-life example: Hospitals use the FTPS system to share and manage patients’ records through an internal network system.
4. FTP over Explicit SSL/TLS (FTPES)
FTP over Explicit SSL/TLS, or FTPES, enhances security by upgrading an FTP connection on port 21 to an encrypted connection. Web and file-sharing services widely adopt this method to ensure secure file transfers.
Real-life Example: A media company might use this FTP type to securely transfer large files between different offices or teams, such as video footage or high-resolution images.
5. Secure FTP (SFTP)
Secure FTP, also known as SSH File Transfer Protocol (SFTP), is not an FTP protocol per se but operates similarly. SFTP is a subset of the Secure Shell (SSH) protocol and runs on port 22. System administrators frequently use SSH for remote and secure access to systems and applications, and SFTP provides a secure file transfer mechanism within SSH.
Real-life Example: A financial institution might use SFTP to securely transfer sensitive financial data and records between departments or with other financial institutions.
6. HTTPS
Hypertext Transfer Protocol Secure (HTTPS) is the secure version of HTTP, the primary protocol for transmitting data between a website and a web browser. HTTPS encrypts data to enhance security during transfer, making it crucial for transmitting sensitive information such as bank account logins, health insurance details, and email services. Websites that require users to log in must use HTTPS. Modern web browsers treat HTTPS as a standard, flagging non-HTTPS websites as unsafe to alert users to potential security risks.
Real-life Example: An online shopping website uses HTTPS to ensure customers’ payment information and personal details are securely transmitted during checkout.
The type of FTP to select for use in the business is very important, bearing in mind that it determines the manner and extent of data transfer within the company. Thus, concerning the FTP type, there is no ultimate solution for your business since it isn’t universal, consisting of the organization’s specific needs.
Some aspects that may be used include the nature of information that is to be transmitted, the degree of protection needed, and compatibility issues with other systems. By analyzing such factors as described above, one is better positioned to choose the appropriate FTP type that suits the business needs and secure critical information.
