## STEP 1: BREACH DETECTION (T+0 minutes)

### 1.1 Initial Breach Detection
- **Time:** 06:20 UTC
- **Detection Method:** Security Information and Event Management (SIEM) alert
- **Alert Details:**
  - Anomaly: Unusual database access pattern
  - Source: Internal network (suspected compromised account)
  - Activity: Unauthorized database queries
  - Data accessed: Member state information
  - Pattern: Data exfiltration attempt
- **System Response:** SIEM automatically triggered security alert, access logged

### 1.2 Alert Escalation
- **Time:** 06:21 UTC (1 minute after detection)
- **Action:** Security Operations Center receives critical alert
- **Initial Assessment:**
  - Breach type: Unauthorized data access
  - Severity: Critical
  - Data accessed: Member state information
  - Response: Immediate containment required
- **Escalation:** Immediate escalation to Security Director, Incident Response Team, and Executive Director

## STEP 2: BREACH ASSESSMENT (T+5 minutes)

### 2.1 Initial Investigation
- **Time:** 06:25 UTC (5 minutes after detection)
- **Investigation Actions:**
  1. Review SIEM logs and alert details
  2. Analyze access patterns
  3. Identify compromised account
  4. Assess data accessed
  5. Determine breach scope
- **Findings:**
  - Compromised account: user@dbis.org (credentials compromised)
  - Data accessed: Member state information (non-sensitive)
  - Access method: Unauthorized database queries
  - Breach scope: Limited (single account, specific data)
  - Data exfiltration: Attempted but blocked

### 2.2 Impact Assessment
- **Time:** 06:27 UTC
- **Assessment:**
  - Data accessed: Member state information (non-sensitive)
  - Data exfiltrated: None (blocked by security controls)
  - System compromise: Limited (single account)
  - Service impact: None
  - Business impact: Low (non-sensitive data)

## STEP 3: INCIDENT CONTAINMENT (T+10 minutes)

### 3.1 Immediate Containment
- **Time:** 06:30 UTC (10 minutes after detection)
- **Containment Actions:**
  1. Disable compromised account immediately
  2. Revoke all active sessions
  3. Block suspicious network activity
  4. Isolate affected systems
  5. Preserve evidence
- **Containment Status:**
  - Compromised account: Disabled
  - Active sessions: Revoked
  - Network activity: Blocked
  - Affected systems: Isolated
  - Evidence: Preserved

### 3.2 Security Enhancement
- **Time:** 06:35 UTC
- **Enhancement Actions:**
  1. Strengthen access controls
  2. Enhance monitoring
  3. Review all account access
  4. Implement additional security measures
- **Enhancement Status:**
  - Access controls: Strengthened
  - Monitoring: Enhanced
  - Account access: Reviewed
  - Security measures: Implemented

## STEP 4: INCIDENT RESPONSE (T+30 minutes)

### 4.1 Incident Response Team Activation
- **Time:** 06:50 UTC (30 minutes after detection)
- **Team Composition:**
  - Security Director (Team Lead)
  - Incident Response Coordinator
  - Technical Director
  - Legal Advisor
  - Communications Director
- **Team Responsibilities:**
  - Coordinate response efforts
  - Investigate breach details
  - Assess impact
  - Communicate with stakeholders
  - Execute remediation

### 4.2 Investigation
- **Time:** 07:00 UTC
- **Investigation Actions:**
  1. Detailed log analysis
  2. Account activity review
  3. Data access verification
  4. System compromise assessment
  5. Root cause analysis
- **Investigation Results:**
  - Breach method: Credential compromise (phishing)
  - Data accessed: Member state information (non-sensitive)
  - Data exfiltrated: None
  - System compromise: Limited
  - Root cause: Phishing attack

---

## STEP 5: REMEDIATION (T+2 hours)

### 5.1 Remediation Actions
- **Time:** 08:20 UTC (2 hours after detection)
- **Remediation Actions:**
  1. Reset all compromised credentials
  2. Implement enhanced authentication (MFA)
  3. Strengthen access controls
  4. Enhance monitoring and alerting
  5. Security awareness training
- **Remediation Status:**
  - Credentials: Reset
  - Authentication: Enhanced (MFA)
  - Access controls: Strengthened
  - Monitoring: Enhanced
  - Training: Scheduled

### 5.2 Post-Incident Review
- **Time:** 08:30 UTC
- **Review Actions:**
  1. Conduct post-incident review
  2. Identify lessons learned
  3. Update security procedures
  4. Enhance security controls
  5. Improve incident response
- **Review Results:**
  - Lessons learned: Identified
  - Procedures: Updated
  - Security controls: Enhanced
  - Incident response: Improved
