Microsoft Defender for Cloud Apps, formerly known as Microsoft Cloud App Security, is a comprehensive cloud access security broker (CASB) solution that provides organizations with visibility into their cloud applications, provides sophisticated analytics to identify and combat cyber threats, and enables them to control data travel across their cloud environment.
Core Features of Microsoft Defender for Cloud Apps:
- Discovery and Visibility: The solution identifies all cloud services used by the company employees, both sanctioned and unsanctioned, by analyzing traffic logs. This helps in assessing the risk level and compliance of each service.
- Data Control and Protection: It controls data by setting granular policies based on the data type, user activity, and risk levels. The policies could involve blocking certain actions or encrypting files to protect sensitive information.
- Threat Detection and Prevention: Microsoft Defender for Cloud Apps utilizes advanced analytics and machine learning to identify potentially malicious behavior and anomalous patterns, thus detecting threats such as ransomware or compromised insiders.
- Governance and Compliance: The platform helps in ensuring that the organization complies with regulatory standards by mapping out where data is stored and allows for governance actions like quarantine or legal hold to be placed on relevant data.
How Microsoft Defender for Cloud Apps Works:
Microsoft Defender for Cloud Apps natively integrates with many popular cloud applications, such as Office 365, Azure, Google Workspace, and third-party services. It works by:
- Logging and analyzing traffic data.
- Monitoring connected applications through API connectors.
- Providing out-of-the-box policies and allowing for custom policy creation.
- Alerting administrators to suspicious activities and potential violations.
- Investigating incidents using contextual information.
