Flow Name: Automated Browser Protection Incident Investigation

Trigger: Blocked Web Incident Alert from Browser Protection System (e.g., DNS Filtering, Secure Web Gateway, Browser Extension, EDR)
Input: Incident Data (includes: blocked URL, user ID, device, threat category, timestamp, and policy violated)

Step 1: Threat Category Check

Condition: Analyze the threat_category or detection_type field.

Branches:

• Malicious (Phishing, Malware, C2): Proceed to Step 2 (Prioritized Investigation)
  
  

• Policy Violation (e.g. Gambling, Adult Content, Unauthorized Tools): Proceed to Step 3 (Standard Investigation)
  
  

• Informational (e.g. Ads, Tracking, Low Risk): End flow – log only, no further action.
  
  

Step 2: Prioritized Investigation (Malicious Blocked Sites)

Collect Context

• Identify the user and device involved
  
  

• Gather incident details: timestamp, URL, category, action taken
  
  

Notify Security Analyst

• Alert security/IT admin via Slack/email with:
  
  

  • Summary of the event
    
    

  • User identity and device name
    
    

  • Link to full incident log (if available in vendor portal)
    
    

Recommended Actions (manual or automated):

• Inform the user about the blocked attempt and remind them of safe browsing habits
  
  

• Schedule follow-up awareness training
  
  

• Check if similar blocks occurred from other users (pattern detection)
  
  

• Escalate to SOC for deeper investigation if repeated
  
  

Step 3: Standard Investigation (Policy Violation)

Log and Review

• Log event with user, device, timestamp, and blocked category
  
  

• Check if this is a first-time or repeat offense
  
  

User Notification

• 1st time: Notify user with a friendly reminder of company browsing policy
  
  

• 2nd time: Notify manager and request user acknowledgment of Acceptable Use Policy
  
  

• 3rd time: Escalate to security team for review
  
  

Output

• Malicious Attempts: Analyst notification + user flagged
  
  

• Policy Violations: Logged + user/manager notified if repeated
  
  

• Informational: Logged only
  
  

Key Considerations

• Error Handling: If user/device details are missing, log the event and flag it for manual review
  
  

• Security: Use secure channels for notifications
  
  

• Customization: Adapt categories and thresholds to match your internal acceptable use and security policy
  
  

Let me know if you want this converted into a checklist, playbook document, or integrated with a specific system like Jira, Slack, or a SOAR tool.

add also to take into account the number of violation by a user and if specific thresholds are met, provide additional training

Perfect — here is the updated, simplified Browser Protection Incident Investigation Flow, now including logic to track the number of violations per user and trigger additional training once thresholds are met:

Flow Name: Automated Browser Protection Incident Investigation

Trigger: Blocked Web Incident Alert from Browser Protection System (DNS Filtering, Browser Extension, EDR)
Input: Incident Data (includes: blocked URL, user ID, device, threat category, timestamp, and policy violated)

Step 1: Threat Category Check

Condition: Review threat_category or detection_type field.

Branches:

• Malicious (Phishing, Malware, C2, etc): → Step 2: Malicious Site Investigation
  
  

• Policy Violation (Gambling, Adult, Hacking Tools, etc): → Step 3: Policy Violation Investigation
  
  

• Informational (Ads, Tracking, Uncategorized): → End flow – Log only, no action.
  
  

Step 2: Malicious Site Investigation

Collect Context

• Retrieve user ID, device name, URL, timestamp, category, number of previous incidents (last 90 days)
  
  

Notify Security Analyst

• Alert via Slack/email with:
  
  

  • Summary of the blocked attempt
    
    

  • User & device details
    
    

  • Link to full logs (from the browser protection platform)
    
    

Recommended Actions:

• 1st or 2nd incident: Notify the user and send secure browsing guidance
  
  

• 3rd+ incident in 90 days:
  
  

  • Automatically enroll user in phishing or secure browsing training
    
    

  • Escalate to manager or IT for review
    
    

  • Consider follow-up discussion or temporary restrictions if pattern continues
    
    

Step 3: Policy Violation Investigation

Logging & Violation Counter

• Log event with user, timestamp, URL category
  
  

• Check number of policy violations in the last 90 days
  
  

Actions by Violation Count:

• 1st Violation:
  
  

  • Notify user with friendly Acceptable Use Policy reminder
    
    

• 2nd Violation:
  
  

  • Notify manager and request user acknowledgment of policy
    
    

• 3rd Violation:
  
  

  • Enroll user in Acceptable Web Use Training
    
    

  • Flag user for IT/Security team review
    
    

• 4th+ Violation:
  
  

  • Escalate for potential disciplinary or technical restrictions (per internal policy)
    
    

Output/Recommendations

Key Considerations

• Tracking: Maintain a rolling 90-day window of incidents per user to enforce thresholds
  
  

• Automation: Can be implemented in SOAR, SIEM, or webhook-based integrations
  
  

• Scalability: Thresholds and escalation actions can be tuned per department or risk profile
  
  

• Error Handling: If user or device data is incomplete, log for manual analyst review
  
  

• Security: Ensure notifications (especially escalations) follow secure internal comms practices
