Identification of Security Risks with Microsoft Defender for Cloud Apps

Defender for Cloud Apps is instrumental in pinpointing potential security risks within an organization’s cloud environment. It achieves this by:

  • Discovery and Assessment:

    With its cloud discovery feature, Defender for Cloud Apps analyzes your traffic logs to provide visibility into cloud applications in use, assesses their risk levels based on regulatory certifications, industry standards, and best practices.

  • App Governance:

    The solution allows for the establishment of governance policies for data in cloud applications. This includes setting up controls based on data type and sensitivity.

  • Threat Detection:

    Utilizing advanced anomaly detection policies, Defender for Cloud Apps can identify risky behavior, such as unusual volumes of data being uploaded or shared, or access from a risky IP address.

Investigation of Security Risks with Microsoft Defender for Cloud Apps

Once a risk has been identified, Defender for Cloud Apps provides tools to help investigate potential security issues:

  • Alerts and Activity Logs:

    The platform generates alerts for a variety of incidents and irregularities. Security analysts can sift through these alerts, using filters to prioritize and investigate activities that could constitute a breach.

  • Context and Insights:

    Defender for Cloud Apps provides contextual information about incidents, including user activity, files involved, and associated risks, enabling a more informed investigation process.

Remediation of Security Risks with Microsoft Defender for Cloud Apps

After a thorough investigation, it is necessary to remedy identified issues to prevent or mitigate security breaches:

  • Automated Policies:

    Use automated policies to trigger specific actions when an alert is raised, such as requiring a user to log in again, suspending a user, or making a file private.

  • Manual Interventions:

    For incidents requiring hands-on attention, Defender for Cloud Apps equips security teams with options for manual intervention—such as removing collaborators from sensitive files or revoking access to an app.

  • Integration Capabilities:

    Microsoft Defender for Cloud Apps integrates with other security tools, like Microsoft Defender for Endpoint, to provide a coherent response to threats.

Examples of Using Microsoft Defender for Cloud Apps

  • Discovery: A company wants to know all the cloud apps its employees are using. They deploy Defender for Cloud Apps, which identifies over 200 apps in use, including some unsanctioned ones. The organization can now decide which apps to allow and monitor formally.
  • Governance: An organization creates policies in Defender for Cloud Apps to block the download of sensitive documents from their SaaS applications to non-managed devices, effectively reducing the risk of data loss.
  • Threat Detection: Defender for Cloud Apps detects an impossible travel activity from a user account, signaling that the same account has been accessed from two different geographies within a short period. This prompts an immediate investigation to determine if the account has been compromised.
  • Remediation: Upon validating the compromise of several accounts, an admin uses the automated governance actions in Defender for Cloud Apps to suspend the accounts and require a password reset, mitigating the potential impact of the breach.
