The cloud security advantage

Microsoft has decades of experience building enterprise software and running some of the largest online services in the world. We use this operational experience to ensure our cloud services have the highest level of built-in security.

Securing systems, applications, and data begins with identity-based access controls. Features such as single sign-on and multi-factor authentication are built into Microsoft business products and services. They help protect your organizational and personal information from unauthorized access while making it available to legitimate users whenever and wherever they need it.

Data is an organization’s most valuable and irreplaceable asset. Microsoft cloud services have many protections in place to prevent unauthorized access or leakage of data within a multi-tenant cloud environment. These include logical isolation with Azure Active Directory authorization and role-based control, data isolation mechanisms at the storage level, and rigorous physical security.  


Encryption serves as the last and strongest line of defense. Microsoft uses some of the strongest, most secure encryption protocols in the industry to safeguard customer data and help you maintain control over it.


The cloud enables Microsoft to take our signal, intelligence, and operational experience and use it to implement and continuously improve enterprise-grade threat protection. From Office 365 to Azure, the power of the cloud provides built-in protection for all of our products and services. 


Examples include:
- Exchange Online Protection’s deployment across a global network of data centers enabling email protection from multi-layered, real-time antispam to multi-engine antimalware protection.
- Microsoft Antimalware for Azure cloud services and virtual machines provides a real-time protection capability to identify and remove viruses, spyware, and other malicious software.


Auditing and logging of security-related events, and related alerts, are important components in an effective data protection strategy. Microsoft business services and products provide you with configurable security auditing and logging options to help you identify gaps in your security policies and mechanisms and address those gaps to help prevent breaches. Microsoft services offer some (and in some cases, all) of the following options: centralized monitoring, logging, and analysis systems to provide continuous visibility, timely alerts, and reports to help you manage the large volume of information generated by devices and services.

Microsoft Azure log data can be exported to Security Incident and Event Management (SIEM) systems for analysis. And Windows Server 2016 provides basic and advanced security auditing and integrates with third-party auditing solutions.
