An Introduction to Microsoft Defender for Cloud Apps
Microsoft Defender for Cloud Apps is a Cloud Access Security Broker (CASB) that supports various deployment modes including log collection, API connectors, and reverse proxy. It provides rich visibility, controls over data travel, and sophisticated analytics to identify and combat cyber threats across all your cloud services. The Defender for Cloud Apps is designed to help you extend the same level of protection you have on-premises to your cloud applications.
Key Features of Microsoft Defender for Cloud Apps
- Threat Protection: It provides advanced threat protection capabilities to detect unusual behavior across cloud apps to identify ransomware, compromised users, or rogue applications, analyze high-risk usage and remediate automatically to limit the risk to your organization.
- Information Protection: It controls and sets policies for data sharing and loss prevention (DLP) in the cloud. It gains visibility into exposure level of data and can apply classification labels for protection.
- App Discovery: It discovers and catalogues cloud apps in use, assess risk levels and business readiness of over 16,000 SaaS applications to assist you with your risk management and cloud strategy.
- Cloud Security Posture Management (CSPM): It assesses compliance and security risk of your cloud environments, provides actionable security recommendations, and helps to investigate, track and remediate potential security issues.
Use Cases for Microsoft Defender for Cloud Apps
Let’s illustrate the capability of Microsoft Defender for Cloud Apps with a few real-world use cases:
- Unsanctioned App Detection and Blocking: One common risk that businesses face today is Shadow IT, where employees use non-approved applications for work. Using Defender for Cloud Apps, administrators can discover and control the use of Shadow IT and unsanctioned apps. Once a risky application is detected, you can block the access using Microsoft Defender for Cloud Apps.
- Data Protection Control: In a scenario where a user attempts to download a sensitive document with credit card information from a sanctioned cloud application onto an unmanaged device, Microsoft Defender for Cloud Apps can detect the data download attempt and limit the access or apply protective measures, such as watermarking.
- Threat Detection: Microsoft Defender for Cloud Apps can spot multiple failed login attempts from different locations. After noticing these suspicious actions, it can alert the administrator and recommend remedial actions such as forcing the user to log in again or blocking future login attempts.
In conclusion, by integrating Microsoft Defender for Cloud Apps into your cloud strategy, organizations can secure their cloud environment, gain control and visibility over their data, and protect against threats. This not only ensures secure and compliant cloud usage but also leverages cloud efficiencies without compromising security. Hence, it plays a crucial role in the preparation for the exam “SC-900 Microsoft Security, Compliance, and Identity Fundamentals”, providing an understanding of how to protect, detect and respond to threats in the cloud environment.
