FTPS transfers data over an SSL-encrypted network. To combat this, FTPS (FTP over SSL) was created. This would allow a third party to view or even edit any transferred files, putting confidential information in jeopardy. Mac FTP clients are also subject to man-in-the-middle attacks, in which attackers alter communications and documents transferred between two computers, often injecting them with malware the recipient then unknowingly downloads.Īnother less likely but still possible FTP security risk is data that “strays” to a remote computer rather than its intended destination. FTP passwords and IDs are transferred over the internet without encryption, potentially exposing them to password sniffing attacks hosted by cybercriminals. Anonymous FTP is not secure and should only be used in situations where files are intended to be public.īut even FTP connections that require an ID and password are at risk. Many FTP sites allow for anonymous transfers, in which users can access and send files without a username and password. In an era when security threats abound, IT professionals must ensure their companies are upholding security best practices.įTP used independently, without the support of third-party software, can pose a number of threats. Passive mode is often the go-to because it avoids bumping up against firewalls. In passive mode, the server uses the command channel to provide the client with the information required to open a data channel, thus putting the client in control of both the command and data channel. With active mode, the client establishes the command channel and the server establishes the data channel. These FTP sessions can function in both active and passive modes. My recommendation is to check out an option like SolarWinds ® Serv-U ®.įTP relies on a client-server relationship in which there’s a separate command channel for controlling files that are uploaded, downloaded, copied, etc., and a data channel for the distribution of the content. While there are some built-in options for file transfer on a Mac, I’ll also highlight why a robust software program is a better option for just about every business. Many companies rely on FTP sites and tools to operate efficiently on a day-to-day basis, whether to send a multi-slide, image-packed PowerPoint presentation or a high-quality company video. File transfer protocol (FTP) is a method for sending large files across the internet. To understand how to use FTP on a Mac, it’s important to fully grasp what FTP is and how it works. IT professionals looking to use FTP on a Mac must fully understand what FTP is, the risks involved, and the tools available to help them increase efficiencies and keep sensitive information secure.
