SCENARIO

A security breach is detected in the GRU Reserve System at 14:30 UTC on 2024-01-15. An unauthorized access attempt to the reserve database is detected by the SIEM system.

Initial Detection:

• Time: 2024-01-15T14:30:00Z
• Source: SIEM alert
• Severity: HIGH
• Type: Unauthorized database access attempt

---

STEP 1: INCIDENT DETECTION AND CLASSIFICATION

Detection:

• SIEM system detects multiple failed authentication attempts
• Pattern indicates automated attack (brute force)
• Source IP: 192.168.1.100 (external, not whitelisted)

Classification:

• Level: Level 2 - High (Security incident without confirmed data compromise)
• Category: Unauthorized access attempt
• Impact: Potential compromise of reserve database

Initial Assessment:

• Attack appears to be automated brute force
• No successful authentication detected
• Database access controls appear to be functioning
• No data access confirmed

---

STEP 2: INCIDENT RESPONSE ACTIVATION

Response Team Activation:

• Time: 2024-01-15T14:31:00Z (1 minute after detection)
• Activation Authority: Security Department Head
• Response Team: Security Incident Response Team (SIRT)

Team Composition:

• Security Department Head (Incident Commander)
• Security Analyst (Lead Investigator)
• Network Administrator (Network Analysis)
• Database Administrator (Database Analysis)
• Legal Advisor (Legal Consultation)

Communication:

• Internal notification sent to Executive Director
• Team members notified via emergency communication system
• Status page updated for stakeholders

---

STEP 3: CONTAINMENT

Immediate Containment Actions:

1. Network Isolation:

   • Source IP blocked at firewall (14:32:00Z)
   • Network segment isolated
   • Access controls tightened

2. System Hardening:

   • Database access restricted to essential personnel only
   • Additional authentication required
   • Monitoring increased

3. Backup Verification:

   • Recent backups verified (14:35:00Z)
   • Backup integrity confirmed
   • Backup access secured

Containment Status:

• Time: 2024-01-15T14:40:00Z (10 minutes after activation)
• Status: Threat contained
• Confidence: High (no successful access detected)

---

STEP 4: INVESTIGATION

Investigation Activities:

1. Log Analysis:

   • Authentication logs reviewed
   • Network logs analyzed
   • Database access logs examined
   • Timeline of events reconstructed

2. Forensic Analysis:

   • Attack pattern analyzed
   • Source investigation initiated
   • Attack tools identified
   • Attack methodology documented

3. Impact Assessment:

   • Systems affected: Reserve database access system
   • Data at risk: Reserve transaction data
   • Access confirmed: None (all attempts failed)
   • Data compromise: None confirmed

Investigation Findings:

• Attack Type: Automated brute force attack
• Attack Duration: 2 hours (12:30-14:30 UTC)
• Attack Attempts: 10,000+ failed attempts
• Successful Access: None
• Data Compromise: None
• System Compromise: None

---

STEP 5: ERADICATION

Eradication Actions:

1. Threat Removal:

   • Source IP permanently blocked
   • Attack pattern added to IDS signatures
   • Similar IP ranges blocked proactively

2. System Hardening:

   • Password policies reviewed and strengthened
   • Account lockout policies reviewed
   • Additional security controls implemented

3. Vulnerability Remediation:

   • No vulnerabilities exploited (attack failed)
   • Preventive measures implemented
   • Security controls enhanced

Eradication Status:

• Time: 2024-01-15T15:00:00Z
• Status: Threat eradicated
• Confidence: High

---

STEP 6: RECOVERY

Recovery Actions:

1. System Verification:

   • All systems verified operational
   • No system changes required
   • Normal operations confirmed

2. Access Restoration:

   • Normal access restored for authorized personnel
   • Enhanced monitoring maintained
   • Additional controls in place

3. Service Restoration:

   • All services operational
   • No service interruption occurred
   • Normal operations resumed

Recovery Status:

• Time: 2024-01-15T15:15:00Z
• Status: Fully recovered
• Service Impact: None

---

STEP 7: POST-INCIDENT ACTIVITIES

Documentation:

• Incident report prepared (2024-01-15T16:00:00Z)
• Timeline documented
• Actions taken documented
• Lessons learned identified

Reporting:

• Executive Director: Immediate notification (14:31:00Z)
• SCC: Notification within 1 hour (15:00:00Z)
• Final report: Within 24 hours (2024-01-16T14:30:00Z)

Lessons Learned:

1. Detection: SIEM system performed well
2. Response: Response time acceptable (1 minute)
3. Containment: Containment effective
4. Prevention: Additional preventive measures needed

Recommendations:

1. Implement rate limiting for authentication attempts
2. Enhance IDS signatures for brute force detection
3. Conduct security awareness training
4. Review and strengthen password policies

METRICS

Response Metrics:

• Detection Time: Immediate (automated)
• Response Time: 1 minute
• Containment Time: 10 minutes
• Investigation Time: 30 minutes
• Recovery Time: 15 minutes
• Total Resolution Time: 45 minutes

Impact Metrics:
