What are Security Baselines?
A security baseline is a collection of security settings and rules agreed upon to be the minimum level of security a system, application, or platform should adhere to. In Microsoft 365, these baselines align with industry standards and best practices for security and are continuously updated to address evolving threats.
Implementing Security Baselines in Microsoft 365
To implement security baselines effectively, it is essential to follow a structured process:
1. Identify Baseline Policies
Microsoft provides several built-in baselines within the Microsoft 365 Security Center and Microsoft Endpoint Manager, aligning with the security configurations recommended by Microsoft for your devices and services.
2. Customize Baselines
While the default baselines are a good starting point, organizations often need to tweak these settings to fit their specific needs. Customizations should be based on a risk assessment that balances security with usability.
3. Deploy Baselines
Baselines can be implemented across Microsoft 365 services such as Azure Active Directory, Microsoft Teams, and Exchange Online. Deployment can be done through Microsoft Endpoint Manager or through group policies in on-premises Active Directory, depending on the service and your infrastructure.
4. Monitor Compliance
After deploying baselines, it’s crucial to monitor devices and services to ensure they remain in compliance with the baseline standards. Microsoft Endpoint Manager provides tools to review and enforce compliance policies.
5. Update and Maintain Baselines
Threat landscapes change, and so do baseline recommendations. Regularly check for updates from Microsoft, and revise the baselines accordingly.
Managing Security Baselines
Managing security baselines involves continuous assessment, enforcement, and improvement:
1. Assessment and Reporting
Utilize tools like Microsoft Secure Score to assess the organization’s current security posture against the baseline and get recommendations for improvement.
2. Enforcement Strategies
Enforce the baselines by applying conditional access policies and automated remediation actions when non-compliance is detected.
3. Regular Review and Audits
Security baselines are not “set and forget” configurations. They should be periodically reviewed to ensure they still meet the required security needs and changes in compliance requirements.
4. Educating Stakeholders
Ensure that staff are trained on baseline policies and understand the importance of security measures being enforced.
Example Security Baseline Configuration
An example of a security baseline in Microsoft 365 might include the following configurations:
| Configuration Category | Setting | Rationale |
|---|---|---|
| Identity Management | Multi-factor Authentication (MFA) required | Adds an additional layer of security for user authentication |
| Device Management | BitLocker Drive Encryption enabled | Protects data at rest by encrypting hard drives |
| Application Management | Macros in Office applications disabled by default | Reduces the risk of macro-based malware |
| Network Security | Firewalls configured to block inbound traffic by default | Limits exposure to network-based attacks |
| Data Security | DLP policies enabled to prevent data exfiltration | Protects against accidental sharing of sensitive information |
Conclusion
Implementing and managing security baselines effectively are critical for maintaining a robust security posture within Microsoft 365 environments. Aspiring professionals preparing for the MS-101 exam should develop a comprehensive understanding of identifying, customizing, deploying, and managing these baselines. By following best practices for security and remaining vigilant with compliance and enforcement, organizations can greatly reduce their vulnerability to threats and ensure their data, devices, and users are well-protected.
