Knowing how to remediate data loss prevention (DLP) violations in Microsoft Defender for Cloud Apps is a crucial aspect of the SC-400 Microsoft Information Protection Administrator exam. In an enterprise setting, DLP is essential for preventing the accidental or intentional loss or leakage of sensitive information. Thus, understanding the remediation process can help in containing and mitigating any potential data leak, which can otherwise harm organizations, financially and reputation-wise.
Microsoft Defender for Cloud Apps is a Cloud Access Security Broker (CASB) that supports various prevention and remediation capabilities. The Defender provides visibility into users’ activities across cloud applications, not just Microsoft services. When integrated with DLP policies, the Defender can detect potential violations and take action accordingly.
Additionally, it also enables the remediation of policy violations, typically in two forms: automated or manual.
Automated Remediation:
In automated remediation, once the DLP policy violation is detected, specific predefined actions, such as block access, restrict sharing, or quarantine, are executed automatically.
To set automated responses in Microsoft Defender for Cloud Apps, follow these steps:
- Navigate to Control followed by Policies.
- Create or click on an existing policy.
- Under the Policy settings, define the filters and conditions for the violation. For instance, you can set a condition to detect when credit card information is shared externally.
- Next, under the Governance section, set the automatic remediation actions. You can choose to quarantine the file or remove the external users from the file’s access list.
- Finally, click Create or Save to complete the policy creation or editing process.
Manual Remediation:
Manual remediation offers more control to the administrator as they can review flagged activities before implementing any measures.
To investigate and initiate manual remediation:
- Navigate to Investigate, then Activity log.
- Filter the activities based on the DLP policy violation.
- From the list of flagged activities, select the violation to review the details. Here, you can analyze the Action taken/Action status.
- For manual remediation, select the violation and take action from the panel (e.g., Suspend user, Remove collaborator etc.).
Remember to do thorough testing of the set conditions and actions in your policy. It’s best to launch these policies in a testing or staging environment first to ensure they’re appropriately configured before deploying them in a production environment.
Conclusion
In conclusion, the principle of triaging DLP violations in Microsoft Defender for Cloud Apps involves setting the right policies, monitoring their enforcement, and taking appropriate remediation actions. This knowledge is vital for the role of a Microsoft Information Protection Administrator, especially in the context of the SC-400 exam.
