Microsoft understands the value of business data and the costly repercussions of losing it. That’s why they’ve released a slew of security and compliance tools for Microsoft 365 subscribers. But given the increasing sophistication and frequency of data breaches, these cloud security solutions aren’t enough to protect your files. You’ll need to follow these seven security tips to prevent data loss in Microsoft 365.

Take advantage of policy alerts

Establishing policy notifications in Microsoft 365’s Compliance Center can help you meet your company’s data security obligations. For instance, policy tips can pop up to warn employees about sending confidential information anytime they’re about to send messages to contacts who aren’t listed in the company network. These preemptive warnings can prevent data leaks and also educate users on safer data sharing practices.

Secure mobile devices

Since personal smartphones and tablets are often used to access work email, calendar, contacts, and documents, securing them should be a critical part of protecting your organization’s data. Installing mobile device management features for Microsoft 365 enables you to manage security policies and access permissions/restrictions, and remotely wipe sensitive data from mobile devices if they’re lost or stolen.

Use multifactor authentication

Don’t rely on a single password to safeguard your Microsoft 365 accounts. To reduce the risk of account hijacking, you must enable multifactor authentication. This feature makes it difficult for hackers to access your account since they not only have to guess user passwords, but also provide a second authentication factor like a temporary SMS code.

Apply session timeouts

Many employees usually forget to log out of their Microsoft 365 accounts and keep their computers or mobile devices unlocked. This could give unauthorized users unfettered access to company accounts, allowing them to steal sensitive data. By applying session timeouts to Microsoft 365, email accounts, and internal networks, the system will automatically log users out after 10 minutes, preventing hackers from opening company workstations and accessing private information.

Avoid public calendar sharing

Microsoft 365’s calendar sharing features allow employees to share and sync their schedules with their colleagues’. However, publicly sharing this information is a bad idea because it helps attackers understand how your company works, determine who’s away, and identify vulnerable users. For instance, if security administrators are publicly listed as “Away on vacation,” an attacker may see this as an opportunity to unleash malware on unattended computers.

Employ role-based access controls

Another Microsoft 365 feature that will limit the flow of sensitive data across your company is access management. This lets you determine which user (or users) have access to specific files in your company. For example, front-of-house staff won’t be able to read or edit executive-level documents, minimizing data leaks.

Encrypt emails

Encrypting classified information is your last line of defense against data breaches. If hackers intercept your emails, encryption tools will make files unreadable to unauthorized recipients. This is a must-have for Microsoft 365, where files and emails are shared on a regular basis.
