How to Protect Microsoft 365 Data from Cyber Attacks Using NIST CSF 2.0

In the rapidly evolving digital landscape, safeguarding Microsoft 365 data against cyber threats has become paramount for organizations worldwide. The upcoming session titled "Incident Response H07: Protecting Microsoft 365 Data from Cyber Attacks," scheduled for May 15, 2025, from 2:15 PM to 3:15 PM CT, aims to equip professionals with the knowledge and tools necessary to fortify their Microsoft 365 environments. This session is part of the Cybersecurity & Ransomware Live! VirtCon and will be presented by Vanessa Toves, a Microsoft 365 Solutions Architect at Druva.

Understanding the NIST Cybersecurity Framework 2.0​

A central focus of the session is the National Institute of Standards and Technology (NIST) Cybersecurity Framework (CSF) 2.0. This framework provides a structured approach to managing and mitigating cybersecurity risks. It comprises five core functions: Identify, Protect, Detect, Respond, and Recover. Each function encompasses specific categories and subcategories that guide organizations in implementing robust cybersecurity measures.

Identify​

The Identify function involves developing an organizational understanding to manage cybersecurity risks to systems, assets, data, and capabilities. For Microsoft 365 environments, this includes:

• Asset Management (ID.AM): Maintaining an inventory of software and SaaS offerings, such as Microsoft 365 Copilot, including details like tenant IDs, licensed users, and administrative roles. (varonis.com)
• Risk Assessment (ID.RA): Evaluating potential threats and vulnerabilities specific to Microsoft 365 services to prioritize risk management efforts.

Protect​

The Protect function focuses on implementing safeguards to ensure the delivery of critical services. Key aspects include:

• Access Control (PR.AC): Enforcing policies like Multi-Factor Authentication (MFA) and Conditional Access to manage user permissions effectively. (threatshub.org)
• Data Security (PR.DS): Utilizing tools like Azure Information Protection to classify and label sensitive data, ensuring appropriate access controls are in place. (inligo.us)

Detect​

The Detect function involves developing activities to identify the occurrence of a cybersecurity event. For Microsoft 365, this includes:

• Anomalies and Events (DE.AE): Implementing continuous monitoring solutions to detect unusual activities within the Microsoft 365 environment. (threatshub.org)
• Security Continuous Monitoring (DE.CM): Utilizing tools like Microsoft Defender for Office 365 to monitor and analyze security events.

Respond​

The Respond function entails taking action regarding a detected cybersecurity incident. Key components are:

• Response Planning (RS.RP): Developing and implementing incident response plans tailored to Microsoft 365 services.
• Mitigation (RS.MI): Executing activities to prevent the expansion of an event and mitigate its effects, such as isolating compromised accounts or services.

Recover​

The Recover function focuses on maintaining plans for resilience and restoring capabilities impaired due to a cybersecurity incident. This includes:

• Recovery Planning (RC.RP): Establishing and implementing plans to restore Microsoft 365 services and data to normal operations.
• Improvements (RC.IM): Incorporating lessons learned from incidents to enhance future response and recovery strategies.

Practical Applications in Microsoft 365​

Integrating the NIST CSF 2.0 into Microsoft 365 involves leveraging various built-in tools and features:

• Azure Active Directory (Azure AD): Manages user identities and access, supporting the Identify and Protect functions by providing secure authentication and authorization mechanisms. (threatshub.org)
• Microsoft Defender for Office 365: Offers threat protection capabilities, aligning with the Detect function by identifying and responding to malicious activities.
• Compliance Manager: Assists in assessing and managing compliance with various standards, including NIST CSF, supporting the Respond and Recover functions.

Session Details​

Attendees of the "Incident Response H07" session will gain insights into:

• Evidence of Attack: Identifying indicators of compromise within Microsoft 365.
• Scope & Containment: Determining the extent of an incident and implementing containment strategies.
• Recovery & Remediation: Executing recovery plans and remediating vulnerabilities to prevent future incidents.

This session is designed for professionals at an introductory to intermediate level and is part of the Cybersecurity & Ransomware Live! VirtCon. Registration provides access to both days of training sessions.
