2. Set Up Retention Policies
Microsoft 365 provides basic retention features like the Recycle Bin (30 days) and the Recoverable Items folder (an extra 14 days). While helpful, these default settings don’t offer long-term protection or automatic backups. Custom retention policies can fill that gap and help meet regulatory requirements.
Understand Your Retention Requirements
Start by identifying your organization’s specific retention needs. Consider industry standards and regulatory rules – like keeping financial records for 7 years or employee communications for 5 years. Use tools like the Microsoft 365 Compliance Center to automate rules for retaining or deleting data based on triggers such as timeframes or specific keywords.
Keep Policies Up-to-Date
Revisit your retention policies every quarter to ensure they meet changing regulations and business demands. Regular updates can help maintain compliance and keep your data protection plan aligned with current needs.
For additional support, third-party tools can enhance Microsoft 365’s retention capabilities. These are discussed further in the backup solutions section. By customizing retention policies, you reduce the risk of accidental data loss and stay compliant with regulations. Pair these policies with strong security measures for a more comprehensive approach to data protection.
3. Use Microsoft 365 Security Features
Microsoft 365 includes several powerful tools to help protect your data. These features work alongside backups and retention policies to create a layered security approach.
Set Up Conditional Access
Conditional Access lets you control who can access your Microsoft 365 resources based on specific factors like location, device, or risk level. Here’s how you can use it effectively:
- Require multi-factor authentication (MFA)
- Block access from untrusted locations
- Enforce device compliance
- Use risk-based authentication to detect and respond to potential threats
Enable Data Loss Prevention Tools
Data Loss Prevention (DLP) tools help safeguard sensitive information, such as financial records, personal identifiers, and intellectual property. These tools can enforce actions like encryption, restrict access, or limit sharing to ensure your data stays secure. Read this blog How to Improve Security With Microsoft 365 Data Loss Prevention for in-depth details to set up DLP.
Use Encryption for Extra Security
Microsoft 365 employs BitLocker to protect data at rest, TLS for data in transit, and IPsec for network communications. You can configure these encryption settings through the Microsoft 365 Security Center. Regularly reviewing and auditing your security settings is crucial to maintaining strong protection.
With 71% of organizations experiencing ransomware attacks in 2022, it’s clear that robust security measures are more important than ever. While Microsoft 365’s built-in tools enhance your defenses, reducing user access where possible can further minimize risks.
4. Limit User Access
Controlling user access is a crucial step in reducing the risk of accidental deletions or exposing sensitive data. With 61% of data breaches tied to compromised credentials and 34% involving internal actors, managing access isn’t just smart – it’s a necessity for keeping your Microsoft 365 environment secure.
Assign Permissions Based on Roles
Role-based access control (RBAC) ensures users only have access to the tools and data they need for their job. This approach keeps sensitive information out of reach for those who don’t need it. Here’s how to set it up in Microsoft 365:
- Clearly define job roles along with their access needs.
- Use the Microsoft 365 Admin Center to create custom roles.
- Assign permissions to specific SharePoint sites, Teams channels, or document libraries.
- Provide temporary access only when absolutely necessary.
For instance, marketing teams should only access marketing files, while finance teams handle financial data exclusively.
Review Permissions Regularly
Unauthorized access remains a major issue, with 71% of organizations reporting it and 55% facing compliance challenges. Regular reviews of permissions help keep your system secure and compliant.
Steps to improve access management:
- Use Microsoft 365’s built-in tools to audit permissions regularly and involve department heads to ensure accuracy.
- Immediately revoke access for employees who switch roles or leave the company.
- Combine access controls with Conditional Access policies to add an extra layer of security.
5. Keep Systems Updated
Keeping your systems updated is crucial to staying protected against new security threats. With cybercrime on the rise, outdated systems are easy targets for attackers. In 2024, the average cost of a data breach hit $4.88 million, making regular updates a must.
Turn On Automatic Updates
Set up automatic updates in the Microsoft 365 Admin Center to ensure users get the latest security patches immediately. To avoid interruptions, schedule updates during off-peak hours. Choose the update channel that fits your organization’s needs, whether it’s the Standard or Preview option.
Test Updates Before Deployment
Before rolling out significant updates, use a staging environment that mirrors your live system. This helps ensure compatibility with essential applications and security measures. Here’s how to approach it:
- Set up a staging environment
- Check compatibility with core applications
- Test security controls thoroughly
- Deploy updates in phases: start with IT teams, then non-critical users, and finally all users once stability is confirmed
After deployment, monitor logs to quickly address any issues. Keep a record of all testing steps and results for compliance and future use.
6. Stay Alert to Security Threats
Cybersecurity threats are constantly changing, and keeping an eye on potential risks to your Microsoft 365 setup is more important than ever. Being proactive about monitoring threats can save both money and headaches.
While tools like backups and retention policies are crucial, threat intelligence adds another layer by spotting new risks early. Tap into resources such as the Microsoft Threat Intelligence Center, MSRC notifications, CISA alerts, and the Microsoft 365 Defender portal for deeper insights and advanced analytics.
Tailor your efforts to focus on risks specific to your environment by weaving threat intelligence into your current security setup:
- Keep an eye on data access and sharing vulnerabilities.
- Monitor risks tied to Teams and Exchange communications.
- Watch for identity-based attacks and attempts to compromise accounts.
To stay ahead, update your security policies regularly based on the latest threat data and perform periodic vulnerability checks. Use this intelligence to fine-tune tools like Conditional Access and DLP policies, ensuring they address new and evolving challenges effectively.
7. Strengthen Data Governance
Effective data governance is essential for meeting compliance standards and ensuring business continuity. With GDPR fines reaching up to €20 million or 4% of global turnover, the stakes are high for organizations to implement strong governance practices.
Organize and Label Data
Azure Information Protection (AIP) simplifies data classification by analyzing content and context. For instance, you can categorize data as:
- Confidential: Financial records or customer data, secured with encryption and strict sharing limits.
- Internal: Business documents or project files are restricted to internal access only.
- Public: Marketing materials or announcements requiring minimal protection.
| Sensitivity Level | Description | Recommended Controls |
|---|---|---|
| Confidential | Financial records, customer data | Encryption, restricted sharing |
| Internal | Business documents, project files | Limited external access |
