Flow Name: Cloud FIle Data Loss Prevention Security Incident Response

Trigger: DLP Policy Violation Alert from Leocybsec DLP Scanner
Input: DLP Alert Data (includes sensitivity label, violation type, affected file(s), user(s), action performed, access type, timestamp, etc.)

📌 DLP Incident Response Flow

1⃣ Alert Severity Check

• High:
  
  

  • Sensitive files (Confidential or Private) externally shared

  • Abnormal access during non-business hours from unusual geolocations

  • Link-based sharing of confidential data

  • Bulk downloads beyond 120% of average

  • Repeated violations from a single user
    
    

• Medium:
  
  

  • Excessive file views (15+ within 30 min)

  • Single instance of Private/Internal data shared externally

  • Suspicious downloads near baseline threshold

  • Unusual user behavior without confirmed policy violation
    
    

• Low:
  
  

  • Access of public/internal files during normal hours

  • Legitimate app/service triggering false positives

  • One-off viewing behavior aligned with business roles
    
    

✅ Actions Based on Severity

• High:
  🚨 Revoke access to files, notify IT and user manager, initiate forensic investigation, and temporarily disable the user account if compromise suspected.
  🛡 Update file permissions and sharing settings.
  🔁 Add violating user to enhanced DLP watchlist.
  
  

• Medium:
  ⚠ Notify the user and manager.
  🔎 Monitor behavior for the next 7 days.
  🧠 Recommend focused security awareness training.
  
  

• Low:
  📩 Log the incident for review, no immediate action.
  🤖 Validate whether it's a false positive via Cribl/Splunk logs.
  
  

2⃣ Violation Type & Scope Assessment

• Single File Violation:
  📎 Validate file sensitivity and exposure path.
  👤 Notify the file owner and advise secure sharing practices.
  
  

• Multiple File Violations:
  🗃 Block user access to affected directories.
  🔁 Perform bulk permissions audit.
  
  

• Cross-User Violation (Org-Wide):
  🌐 Conduct pattern analysis for shared behavior.
  🏛 Evaluate policy tuning and escalate to compliance/legal if needed.
  
  

• Repeated Offenses (Same User):
  🚨 Flag user for HR/security meeting.
  📚 Enroll in mandatory DLP policy refresher.
  
  

🎯 Recommended Actions for Continuous Data Security

• 🔐 If external sharing is detected:
  Immediately revoke links and enforce stricter access controls.
  
  

• 🔄 If bulk download or excessive file views detected:
  Set up behavior-based adaptive policies and thresholds.
  
  

• 👀 If off-hours or geolocation anomaly:
  Review login logs, enforce conditional access or MFA.
  
  

• 📬 If sensitive access changes occur:
  Block sharing type, notify owner, and audit all similar files.
  
  

• 🧠 If user appears unaware:
  Assign contextual awareness training focused on cloud data hygiene.
  
  

📊 Alert Sensitivity Levels

⚙ Optional Enhancements (Post-Incident)

• Implement MLOps feedback loop to fine-tune false positive/negative detection.
  
  

• Introduce DLP Policy Tuning Workflow in case of repeated false alerts.
  
  

• Create a risk dashboard in Splunk summarizing top violators, policy breach types, and recurring issues.
