Data is the most essential part of every organization, so the tools we use in the workplace must ensure data security and protect data integrity, mainly collaboration and communication tools.
By 2020, millions of organizations will have to make rapid changes in their business structure and way of working to support remote working. It resulted in the rise of several collaboration and video conferencing tools, which became extremely popular among organizations. Microsoft Teams is currently at the forefront, followed by Google Meet, Slack, and more. Since its launch, Teams has become the fastest-growing communication and collaboration tool with having 250million+ active users.
Teams is a part of Office 365 cloud applications. It integrates with OneDrive, SharePoint, and Outlook to offer seamless and robust file-sharing capabilities with instant messaging and video conferencing.
Because of all these advanced features, Teams is currently the most popular collaboration and video conferencing tool among organizations. But few cases of data leakage and accidental sharing put a question – how secure is Microsoft Teams?
This post will discuss different aspects of Microsoft Teams security and what we can do to keep it secure while still maximizing end-user collaboration service.
Before moving further in the blog, it’s important to know why Microsoft Teams Security is among hot topics. So, below are a few reasons behind it:
Before cloud computing, the firewall configuration was the key pillar for security, and you used to rely on an organization’s firewall as a secure perimeter. All the servers, such as the application server, Exchange Server, SharePoint Server, file server, and Skype for Business Server, ran behind a firewall in your data center.
But the advent of cloud services like Office 365 made everything easy and started allowing users to work and communicate over files outside the data center. Now companies don’t require to depend on their own servers and firewall as they can subscribe to Cloud services for applications like Exchange, SharePoint, OneDrive, Office 365, etc. Cloud security services are much better than a firewall.
And the security of Microsoft Teams goes much beyond than that.
The answer to this question is – Yes. Undoubtedly, Microsoft Team is designed to be highly secure. It ensures that file sharing and communication occur among known and authorized users who have data access.
But just as we have to lock the doors of our house, we need to employ the lock in Office 365 so that it strikes the perfect balance between ease of use and security.
Before moving to it, firstly, let’s discuss what can be a security threat to Microsoft Teams. Below are some significant threats:
There are several ways to enhance Teams’ security and minimize the security risks. Some of Microsoft Teams’ best security practices are listed below:
Teams’ governance policies are one of the best ways to enforce security. These policies determine how the organization will perform internally, how the end-users will use the app, who can create Teams accounts, and what information or data users can share. It’s essential to appoint a Teams administrator to implement governance policies across the organization.
When it comes to security, you can also consider these points:
Office 365 provides a few additional features to secure your data or information
Data access control is important in securing data and file sharing outside the organization. You can provide external as well as guest access to the Teams channel. Let’s discuss both these access controls in detail:
By the way, the administrator can disable guest access or govern the guests’ capabilities, such as whether they can edit or delete chats in channel posts, share files, etc. Configuring or monitoring guest access is crucial to avoid data breaches regularly.
Here are some other methods to control external or guest access in your Teams channels:
Monitoring helps you in analyzing how users are interacting with Teams. You can use insights to check user behavior and what you need to change to achieve better Teams security.
Teams also provide limited monitoring capabilities to prevent blanket permission of third-party apps offered by Office 365 that require access to users and corporate data. Admins can pre-create a list of permitted third-party apps. If Team requires any non-listed app, they can manually check it before granting permission. It prevents teams from any external attack.
You can monitor teams’ activity on analytics and reports in the admin center.
If the sensitive information is still in the Team even after it has outlived its purpose, it presents a security risk, and there is a chance of data leakage or data loss. Use these three policies to manage data:
Microsoft Teams has become important to business continuity, and with its growing usage, it becomes essential to understand all significant areas of Microsoft Teams’ security. I hope this blog gives you an overview of all major areas required for Microsoft Teams security.
