What is FTP? Everything You lot Need to Know About File Transfer Protocol

Compliance Cyber and Data Security FTP Cloud FTP Solutions Secure File Sharing The Deject

FTP, as well known as file transfer protocol, is a process that organizations tin can use to transfer big and/or sensitive files from one location to some other. Secure "versions" (or alternatives) of FTP (SFTP, FTPS) are especially useful in the defence force, legal, healthcare, manufacturing, and finance industries. However, FTP generally speaking, is used in almost every manufacture where the sharing of data is necessary.

But what is FTP exactly? At FTP today, nosotros have a team of defended secure file transfer experts who are ever available to talk about your organization and its file transfer needs. Go along reading for a deep dive into FTP, and contact the states if y'all would like to schedule a fourth dimension to discuss FTP and what it could mean for your business.

FTP History

The concept of FTP dates back to April 1971, when Abhay Bhushan first wrote the specification for file transfer protocol — which he published in RFC 114. In its earliest years, FTP ran on NCP, which stands for Network Control Program, and facilitated the protocol stack on computers hosting the ARPANET (the predecessor to the mod-day internet). FTP moved to Manual Control Protocol/Internet Protocol (TCP/IP) in the 80s, where it remains today.

In the 1990s, new standards enabled firewall-friendly FTP (in 1994), proposed security extensions (1998) and added support for IPv6 while also defining a new version of passive mode (1998). As you'll notice below, FTP and its capabilities accept come a long way in the modern age.

How Does FTP Work

In simplest terms, FTP is a method for briefly connecting computers, called "clients" and "servers," in guild to facilitate the transfer of files from 1 to the other. When you think of servers, yous most likely recollect of web servers that hold webpage-related files for the internet or of file servers on your office network. FTP servers are similar to web servers, just they are different in that they agree files for upload and download rather than files to be retrieved as web pages through browsers. Websites operate on HTTP/HTTPS rather than FTP, which we'll address later in this post.

FTP servers facilitate both uploads and downloads. Files are transferred from local computers or servers to remote FTP servers during uploads. Files are transferred from FTP servers to local servers or computers during downloads.

Metaphorically speaking, the local systems tin can be thought of as the senders of letters and the receivers of letters. FTP as a protocol would be similar a post truck used to evangelize letters. And the FTP server can be thought of every bit the mail service role or postal service distribution middle. For example, imagine Company A needs to transport a big amount of files to Visitor B. Visitor A volition upload the files to an FTP server, and so Visitor B will transfer the data from the FTP server to its own computer.

How do computers find the FTP servers they're looking for? All FTP servers have an address. The accost may expect like a spider web accost (starting with ftp://), or it may look more similar the cord of numbers that represent an IP address. While some FTP servers do non crave login credentials to gain access, called an "anonymous" connectedness, near FTP servers have in identify security features that require a username and password for access.

Is Your SFTP Provider Protecting Your External Files?

Your current SFTP provider could exist putting your business at serious risk. Have this short quiz and find out if you are practicing secure procedures in society to protect your company's disquisitional information.

FTP Security

We've already noted that FTP was not originally created for security. In fact, FTP as originally conceived was highly vulnerable to brute-force attacks, port stealing, username enumeration and other threats. But, today, there are secure versions of FTP that make it safe as the protocol of choice for organizations that need to store and transfer even the most sensitive of files and information.

FTPS builds on the FTP foundation through the add-on of a send security layer, or TLS, which replaced the now deprecated secure sockets layer (or SSL). There are ii types of FTPS: implicit FTPS and explicit FTPS. Explicit FTPS is the newer and nigh normally used protocol. When using explicit FTPS, a connection is established on the same control port as FTP (port 21), and then an SSL/TLS connection can be required by the client or required by the server. The TLS/SSL connectedness is what encrypts and secures the files. Additional ports volition open for information to laissez passer, as port 21 is for the issuing of commands merely. The FTP client and FTP server will negotiate which ports need to exist used to complete the file transfers.

SFTP is another option for file transfer protocol security. SFTP uses a secure trounce (Or SSH) data stream to protect the connection during file transfers. Unlike FTPS, which requires many ports to complete file transfers, SFTP uses simply port 22 for both commands and data. Both FTPS and SFTP are commonly used protocols for securely transferring files. The all-time choice for your organization will depend on the security controls you lot demand and compatibility with other systems. Many lean toward SFTP considering it but requires the unmarried port to be open.

The Benefits of FTP & Related Protocols

FTP and the more secure protocols mentioned in the section above take become widely accepted for file transfer in the 21st century. Why has FTP go the standard? Because the benefits of using FTP are well-known and widely appreciated by individuals and organizations that need to transfer sensitive files in a secure mode. Here's a look at the half dozen primary benefits of FTP:

i. Chapters

We've all been caught in a state of affairs where a large file simply won't adhere and send via electronic mail. FTP solves this problem by facilitating the transfer of large individual files, every bit well as large amounts of smaller files. If you choose a method of transferring files that does non have the chapters you demand, you will find that transfers and connections oftentimes fail. Naturally, this is highly inefficient for any organization that needs to transfer large files on a regular basis.

ii. Security

While FTP as conceived in 1971 did have security vulnerabilities, there are now encrypted file transfer protocols that layer on acme of FTP the security needed for sensitive files. More specifically, FTPS and SFTP are options for organizations that need highly secure file-transfer capabilities.

3. Control

Most modern FTP providers offering administrative dashboards that give users a high level of control over their files. These controls allow administrators to grant permissions on a user-by-user footing to upload, download, share, edit, and even delete files stored on FTP servers.

iv. Efficiency

When yous identify and implement the right FTP solution for your organization, you can institute a highly efficient file transferring workflow that all squad members sympathize and use. Once again, many organizations are regularly handling large and sensitive files. By using FTP to establish an efficient workflow, these organizations are able to movement faster, practice more, and generally raise their operations.

5. Redundancy

The best FTP providers as well provide regular server backups so that your sensitive files always remain prophylactic in case of a natural disaster or some other incident that compromises one server. FTP backup servers are typically located in completely different geographical regions. This ensures that there'south no break in an organization's access to their files.

6. Automation

Automation is likely the most significant benefit of using these protocols. Transfers tin can exist easily configured and scheduled to happen with no human being intervention. For case, it's possible to synchronize local and remote folders every v minutes, 24/7.

FTP vs. HTTP

FTP and HTTP are both transfer protocols that play important roles in the digital world. But there are primal differences between FTP vs. HTTP that are of import to know.

You probable know HTTP as the protocol used to retrieve files on the internet for viewing within browsers. HTTP is perfect for this activity, because information technology efficiently transfers small files — like webpages. FTP, as noted to a higher place, is ideal for transferring much larger files.

On the technical side, HTTP uses TCP port 80, and FTP uses TCP port 21. In that location's typically no authentication required with HTTP, which is why you are able to admission files on the internet without logging in each time. Conversely, FTP almost always requires user and countersign authentication. Lastly, HTTP creates a data connection only, while FTP creates both information and command connections.

As we've written earlier, both FTP and HTTP play of import roles as transfer protocols. That said, anytime at that place's a demand for the transfer of large files or large amounts of files, FTP is the only efficient, reliable solution.

FTP Terms to Know

The FTP world is total of terms and acronyms that can audio like and that often confuse users. To assistance you improve understand and distinguish between these terms and acronyms, here's an FTP glossary to reference:

• FTPS: FTPS is a method of encrypted FTP that uses a TLS/SSL connection to protect files.
• Explicit FTPS (or FTPeS): Explicit FTPS is the newer method of FTPS. It uses a traditional FTP connectedness and then adds an additional layer of security by creating a TLS/SSL connection via port 21.
• Implicit FTPS: Implicit FTPS is the older method of FTPS. It also layered security on meridian of a traditional FTP connexion, but it created the TLS/SSL control connectedness through a separate port — port 990.
• SFTP: SFTP uses SSH (likewise known as Secure Shell) encryption via port 22 to secure files equally they are existence transferred.
• FTP Server: An FTP server is the physical (or virtual) machine where files are stored and secured subsequently uploads and before downloads.
• HTTPS: HTTPS is the secure version of HTTP, which stands for hypertext transfer protocol. HTTPS uses a secure sockets layer (SSL) for encryption, much the same way FTPS uses TLS/SSL.
• Authentication: Authentication is the process of validating that a user is approved by requesting a username and password.
• SSH: SSH is besides known every bit secure crush or secure socket shell. Information technology'southward used in SFTP to create a secure connection for file transfers.
• SSL: SSL is as well known as secure sockets layer, which is an encryption protocol that has been deprecated and replaced by TLS. SSL was used to encrypt files as part of FTPS, but more recently has been plant to be vulnerable.
• TLS: TLS is as well known every bit send layer security, which replaced the deprecated SSL protocol for encryption. TLS is used to encrypt files as function of FTPS.
• Permissions: Permissions are given to users by an FTP admin. Permissions can be granted to upload, download, share, edit or delete files on an FTP server. The authentication process is used to validate users and ensure they operate within their permissions.
• Port 22: Port 22 is the secure shell advice port used specifically for SFTP.
• Port 21: Port 21, 1 of the ports used by FTP, is the default control port for FTP. After a valid username and password are entered into the FTP client, port 21 opens automatically.
• Port 20: Port 20 is used past the FTP client to create the second "agile" connection necessary for file transfers to occur. "Passive" FTP opens many more data ports and is more common today.
• Port 990: Port 990 is the port used as the implicit FTPS command channel. Port 989 may then be used for an active data port, or other ports are used every bit passive data ports.
• Encryption: Encryption is the practice of securing digital data by using mathematics. Dissimilar types of encryption are used in FTP transfers for security.
• In-Transit Encryption: In-transit encryption means that files are secured as they movement betwixt an FTP server and a reckoner.
• At-Rest Encryption: At-rest encryption ways that files are secured while they are stored on an FTP server.
• IP Address: An IP address is the unique code used to identify any device continued to the internet or a different network.
• CLI: CLI, or command line interface, can be used to send a file from one computer or server to another using the IP address and an net port.
