You’re going to be hearing more and more about “VISIBILITY” from Ipswitch, so I’d like to quickly start this blog post with our definition of visibility in the context of files and data flowing into, within and out of your company:
Visibility: “Unobstructed vision into all data interactions, including files, events, people, policies and processes”
Fast, easy access to critical file and data transfer information is a must-have – it’s critical to the success of your business. Whether it’s tracking and reporting on SLAs, analyzing file transfer metrics to identify bottlenecks and improve efficiency, or providing customers and partners with easy self-service access to the file transfer information they require – as well as countless other business objectives – unobstructed visibility is imperative.
Having one consolidated view into all of the systems and processes involved in your organizations file and data transfers will deliver tremendous business value and a competitive edge. Please do take a couple of minutes to watch Ipswitch’s Frank Kenney share his perspective on why visibility is important.
This morning I was asked if I recommended using transport encryption or file encryption to protect company files and data.
My answer: “Use both of them, together!”
For starters, here’s a real quick summary of both encryption types:
- Transport encryption (“data-in-transit”) protects the file as it travels over protocols such as FTPS (SSL), SFTP (SSH) and HTTPS. Leading solutions use encryption strengths up to 256-bit.
- File encryption (“data-at-rest”) encrypts an individual file so that if it ever ended up in someone else’s possession, they couldn’t open it or see the contents. PGP is commonly used to encrypt files.
I believe that using both together provides a double-layer of protection. The transport protects the files as they are moving…. And the PGP protects the file itself, especially important after it’s been moved and is sitting on a server, laptop, USB drive, smartphone or anywhere else.
Here’s an analogy: Think of transport encryption as an armored truck that’s transporting money from say a retail store to a bank. 99.999% of the time that armored Brinks truck will securely transport your delivery without any incident. But adding a second layer of protection – say you put the money in a safe before putting it in the truck – reduces the chance of compromise exponentially, both during and after transport.
One last piece of advice: Ensure that your organization has stopped using the FTP protocol for transferring any type of confidential, private or sensitive information. Although it’s an amazing accomplishment that FTP is still functional after 40 years, please please please realize that FTP is does not provide any encryption or guaranteed delivery – not to mention that tactically deployed FTP servers scattered throughout your organization lack the visibility, management and enforcement capabilities that modern Managed File Transfer solutions deploy.
