Multi-Layered Defense: The Security Features of Microsoft 365

by Emily Houssier

In today’s digital age, the security of your information is more important than ever. The rise of remote work and cloud computing has made it essential to ensure the protection of your data from cyber threats. Microsoft 365 is a popular suite of cloud-based services that offer a range of productivity and collaboration tools. In this article, we will explore the security features of Microsoft 365 and how they can protect your organization’s data. 

Protecting Your Data: A Look at Microsoft 365 Security 

Multi-Factor Authentication 

Multi-factor authentication (MFA) is a security feature that requires users to provide two or more forms of identification before accessing their accounts. Microsoft 365 supports MFA, making it more difficult for unauthorized users to access your data. When users attempt to sign in to their account, they are prompted to enter a password and a second form of identification, such as a verification code sent to their phone or email. MFA significantly reduces the risk of unauthorized access to your organization’s data. 


Data Encryption 

Microsoft 365 uses encryption to protect your data both in transit and at rest. When data is transmitted, it is encrypted using Transport Layer Security (TLS), which ensures that data cannot be intercepted or tampered with during transmission. When data is stored, it is encrypted using BitLocker, a feature that encrypts the hard drive on which the data is stored. This means that even if someone gains access to the physical hard drive, they will not be able to read the data without the decryption key. 


Advanced Threat Protection 

Microsoft 365 includes Advanced Threat Protection (ATP), which provides advanced security features to protect against cyber threats. ATP includes features such as Safe Links, which checks URLs in emails and Office documents to ensure they are safe before opening them, and Safe Attachments, which checks attachments for malware before allowing them to be opened. ATP also includes anti-phishing measures, such as impersonation protection, which detects and blocks emails that appear to be from legitimate senders but are fake. 


Compliance and Data Protection 

Microsoft 365 offers a range of features to help your organization meet compliance requirements and protect your data. The suite includes built-in compliance features, such as eDiscovery and Audit Logs, which help you manage your data and comply with regulations. Microsoft 365 also offers data protection features, such as Data Loss Prevention (DLP), which helps prevent the accidental or intentional disclosure of sensitive information. 


Identity and Access Management 

Identity and Access Management (IAM) is a critical aspect of security in Microsoft 365. IAM controls who can access your data and how they can access it. Microsoft 365 includes Azure Active Directory (AAD), a cloud-based IAM service that allows you to manage users and their access to your organization’s data. AAD supports features such as single sign-on (SSO), which allows users to sign in once and access multiple applications, and conditional access, which allows you to control access to your data based on factors such as the user’s location or device. 


5 Components for Securing Microsoft 365 – Gartner® Recommendations:

Security and risk management leaders responsible for the application and data security should: 

  • Protect against Microsoft 365 unauthorized access and user errors by establishing a strong foundation for an identity and access management (IAM) strategy on which all other controls rely. 
  • Comply with internal policies and external regulations by monitoring user and application behaviour. 
  • Protect your Microsoft 365 subscriptions from receiving or distributing malicious content by implementing Microsoft Defender, supplementing Microsoft’s basic security capabilities with third-party gateways or integrated solutions. 
  • Secure and monitor Microsoft 365 content (both in motion and at rest) to prevent unauthorized access or data loss by implementing Microsoft Information Protection (MIP).  
  • Maintain control over the content on managed and unmanaged devices by implementing application and device protection.
