Immediate Steps with SecureStack™

1. Detect the Breach with Microsoft Sentinel
Use advanced threat detection rules in Sentinel to identify suspicious access patterns, credential misuse, or mass data exfiltration. Automated investigations can help confirm if a breach has occurred.

2. Activate Microsoft Defender for Cloud Alerts
Defender for Cloud surfaces immediate security posture issues—such as exposed storage accounts, weak authentication methods, or vulnerabilities—so you can triage and remediate affected assets.

3. Reset Credentials and Enforce MFA
After detection, prompt impacted users to reset credentials. Use Azure Active Directory and Conditional Access policies to enforce multifactor authentication (MFA) across accounts.

4. Classify Exposed Data with Microsoft Purview
Scan impacted storage or databases using Purview to determine if sensitive data—such as PII, financial records, or health information—was involved in the breach. This aids in compliance and disclosure requirements.

Additional Recovery Actions

5. Leverage Copilot in Azure for Root Cause Analysis
Use Copilot to ask:
“Which users accessed sensitive files during the breach window?”
“What misconfigurations led to the unauthorized access?”
Copilot helps accelerate investigations and provides remediation guidance in natural language.

6. Apply a Data Access Freeze
Based on findings, revoke or temporarily freeze access to specific storage accounts, files, or user groups using Defender for Cloud recommendations or Microsoft Entra controls.

7. Enable Continuous Monitoring
Deploy ongoing monitoring using Sentinel Workbooks and Purview compliance insights. Ensure alerts are triggered for anomalous logins, large file transfers, or newly exposed data.

Long-Term Resilience Strategy

1. Harden Security Posture
Defender for Cloud Secure Score offers prioritized hardening recommendations—like enabling encryption, endpoint protection, and secure identity controls across subscriptions.

2. Review & Update DLP Policies in Purview
Ensure updated data loss prevention (DLP) policies are in place for sensitive categories (e.g., Social Security numbers, payment card data). Create labels and block unauthorized movement or downloads.

3. Educate Teams & Use Microsoft Defender XDR
Enable alert correlation and response across endpoints, email, identity, and data using Microsoft Defender XDR. Provide training on phishing, insider risk, and breach response protocols.
