The Sunset of Skype for Business Is Your Microsoft® Teams Security Deadline
Customers of Skype for Business have been preparing for the fateful day when Microsoft will end support for the service. Microsoft has finally announced a date when Skype for Business Online will be retired: July 31st, 2021.
As when any cloud service shuts its doors, customers must come up with a strategy to move users over to a new service. Microsoft provides resources for customers making the move from Skype for Business to Teams, which can help companies learn from best practices and plan their projects.
Security should be a key consideration of the rollout; especially given the fact that Microsoft Teams is highly connected to services like Sharepoint and OneDrive and has a completely unique platform for collaboration that customers can take advantage of. Office 365 has become a top priority for security teams as companies consistently use its cloud services and securing Microsoft Teams should not be taken lightly.
Best Practices for Securing Users and Data on Microsoft Teams
Microsoft Teams provides customers with powerful security features. In order to meet common security requirements around controlling access to data and user accounts, however, customers will need to compliment Teams native security with their own security capabilities.
A Cloud Access Security Broker (CASB) provides a dedicated cloud security solution for an organization’s overall cloud usage and individual applications. A CASB can help companies satisfy their security requirements for using Microsoft Teams with many controls protecting data and user accounts.
McAfee’s CASB, MVISION Cloud, offers a comprehensive set of security features for Microsoft Teams that enforce a necessary level of protection for sensitive data. Importantly, a CASB can consistently apply these security controls across cloud applications – even extending policies from on-premises security tools such as DLP solutions.
Here are the security capabilities companies should plan to achieve with a CASB project for Microsoft Teams:
A unified, cloud-native security platform— MVISION Cloud CASB technology (DLP, threat protection, collaboration control, activity monitoring, access control) in a single, unified platform—offering a frictionless, cloud-native solution for organizations to consistently protect their data and defend against threats in the cloud.
Modern data security—IT can extend existing DLP policies to messages and files in all types of Teams channels, enforcing policies based on keywords, fingerprints, data identifiers, regular expressions and match highlighting for content and metadata.
Collaboration control—messages or files posted in channels can be restricted to specific users, including blocking the sharing of data to any external location.
Comprehensive remediation—enables auditing of regulated data uploaded to Microsoft Teams and remediates policy violations by coaching users, notifying administrators, quarantining, tombstoning, restoring and deleting user actions. End users can autonomously correct their actions, removing incidents from IT’s queue.
Threat prevention—empowers organizations to detect and prevent anomalous behavior indicative of insider threats and compromised accounts. McAfee captures a complete record of all user activity in Teams and leverages machine learning to analyze activity across multiple heuristics to accurately detect threats.
Forensic investigations—with an auto-generated, detailed audit trail of all user activity, McAfee MVISION Cloud for Microsoft Teams provides rich capabilities for forensics and investigations.
On-the-go security, for on-the-go policies—helps secure multiple access modes, including browsers and native apps, and applies controls based on contextual factors, including user, device, data and location. Personal devices lacking adequate control over data can be blocked from access.
Collaboration applications like Microsoft Teams remove barriers to the convenient and efficient sharing of data across internal teams and external partners. A CASB allows organizations to enforce security for collaboration applications without sacrificing the functionality and user experience that makes businesses use collaboration applications in the first place. McAfee calls this security framework cloud-native data security, and it allows companies to take advantage of the business benefits of cloud services while meeting their strictest security requirements.
The ease of implementing controls through a CASB can ensure security is not the barrier to migrating users from Skype for Business to Microsoft Teams.
