Should I use Skype for Business, Teams or Zoom?

After months of telecommuting for classes and work, we’re all getting familiar with Ohio State’s collaboration tools available to us for working, teaching and learning. We recently added a videoconferencing feature to Teams, in addition to the chat, instant messaging and collaboration tools you may already be using.

Which tools should you use? Each has pros and cons. This article may help you decide which tool is best for your needs. However, if a feature is popular in one tool, other tools are quick to integrate that feature into their offering as well. You’ll see in the chart below, that many tools have similar features.

No Tool Is Perfect: Things You Should Know

Encryption

Teams, CarmenZoom and Skype for Business can all encrypt voice, video, file transfers and instant messages. All three run through Ohio State servers and uses our preferred level of encryption, which is end-to-end. End-to-end encryption allows only the sender and receiver to access data. This is a recent update for Zoom, which used to have only “transport-level security (TSL).” This type of encryption sends all content through the server of the host company (Zoom) and content can be accessed by that company. Zoom now uses TSL only when users have free accounts. This lesser level of encryption will only impact you if you have meetings with someone outside the university or medical center, and only if they do not have a paid account with Zoom and are using the free version.

Security

We have outlined known issues with Zoom bombing. Your best defense is to learn what settings you need to adjust to prevent abuse by participants or uninvited guests. Skype for Business, Teams and Zoom allow you to use a “Waiting Room” feature so the host can control who is entering the meeting. The host can “lock” the meeting once all attendees have connected.

Data Security

Refrain from accessing university Private (S3) or Restricted (S4) data when working from a personal device. If you are not sure what level of data you are using, a free activity on Cybersecurity for You explains S3 or S4 data. Do not save university data directly to your personal device or hard drive.

Private Messages

When using Zoom and recording locally to your device, private messages that you had access to are recorded as well. If you choose to record locally and then share a recording and the chat transcript, it will include those messages that you intended to be private between you and other participants. Recording to the Zoom cloud (which is recommended) will only record the chat messages sent to everyone.

Wexner Medical Center

The medical center has opted out of Teams and other Office 365 programs (because they have different security requirements), so Teams is not a viable option for collaborating with medical center teammates. The university and medical center are working together to create a common platform in teams that will make collaboration easier.

So in many cases you will find that one tool isn’t necessarily better than another – sometimes it’s just a matter of personal preference.

As our learning and security teams outlined in its statement last week, you should always be thoughtful about information you are using with any of these tools and observe the precautions outlined by Ohio State’s Enterprise Security Team.
