STEP 1: INCIDENT DETECTION (T+0 minutes)

1.1 Automated Detection

• Time: 14:32 UTC
• Detection Method: Intrusion Detection System (IDS) alert
• Alert Details:
  • Source: External IP address (203.0.113.45)
  • Target: DBIS authentication server (auth.dbis.org)
  • Activity: Multiple failed login attempts (15 attempts in 2 minutes)
  • Pattern: Brute force attack pattern detected
• System Response: IDS automatically blocked source IP and generated alert

1.2 Alert Escalation

• Time: 14:33 UTC (1 minute after detection)
• Action: Security Operations Center (SOC) analyst receives alert
• Initial Assessment:
  • Alert classified as "High Priority"
  • Pattern indicates potential security threat
  • Immediate investigation required
• Escalation: Alert escalated to Security Director and Incident Response Team

---

STEP 2: INCIDENT ASSESSMENT (T+5 minutes)

2.1 Initial Investigation

• Time: 14:37 UTC (5 minutes after detection)
• Investigation Actions:
  1. Review IDS logs and alert details
  2. Analyze attack pattern and source
  3. Check authentication server logs
  4. Verify system status and integrity
• Findings:
  • Attack targeted admin account (admin@dbis.org)
  • All login attempts failed (account locked after 5 attempts)
  • No successful authentication detected
  • System integrity verified (no signs of compromise)
  • Source IP geolocated to unknown location

2.2 Threat Assessment

• Time: 14:40 UTC (8 minutes after detection)
• Assessment:
  • Threat Level: Medium-High (potential for escalation)
  • Impact: Limited (no successful access, account protected)
  • Urgency: High (requires immediate containment)
• Classification: Incident classified as "Unauthorized Access Attempt - Brute Force Attack"

2.3 Incident Declaration

• Time: 14:42 UTC (10 minutes after detection)
• Action: Security Director declares security incident
• Incident ID: SEC-2024-001
• Classification: Critical (due to target account and attack pattern)
• Notification: Incident Response Team activated

---

STEP 3: INCIDENT CONTAINMENT (T+15 minutes)

3.1 Immediate Containment Actions

• Time: 14:47 UTC (15 minutes after detection)
• Actions Taken:
  1. Source IP Blocking: Source IP permanently blocked at firewall level
  2. Account Protection: Admin account verified as locked and secured
  3. Network Isolation: Authentication server isolated from external network temporarily
  4. Enhanced Monitoring: Additional monitoring activated for related systems
• Containment Status: Threat contained, no further access attempts possible

3.2 System Verification

• Time: 14:50 UTC (18 minutes after detection)
• Verification Actions:
  1. Verify no successful authentication occurred
  2. Check for any unauthorized access to systems
  3. Verify account security (password strength, MFA status)
  4. Check for any data exfiltration or system modifications
• Results: All verifications negative - no compromise detected

3.3 Network Analysis

• Time: 15:00 UTC (28 minutes after detection)
• Analysis Actions:
  1. Analyze network traffic patterns
  2. Check for related attack attempts on other systems
  3. Review firewall logs for similar patterns
  4. Check for any botnet or coordinated attack indicators
• Results: Isolated attack, no evidence of coordinated campaign

---

STEP 4: INCIDENT INVESTIGATION (T+30 minutes)

4.1 Detailed Log Analysis

• Time: 15:02 UTC (30 minutes after detection)
• Analysis:
  1. Review complete authentication logs
  2. Analyze attack timeline and pattern
  3. Identify attack tools and methods used
  4. Review related security events
• Findings:
  • Attack duration: 2 minutes (14:30-14:32 UTC)
  • Attack method: Automated brute force tool
  • Target: Single admin account
  • Attack pattern: Sequential password attempts
  • No successful authentication

4.2 Threat Intelligence

• Time: 15:10 UTC (38 minutes after detection)
• Intelligence Gathering:
  1. Query threat intelligence databases for source IP
  2. Check for known threat actor associations
  3. Review similar incidents in industry
  4. Analyze attack attribution (if possible)
• Results:
  • Source IP not previously associated with known threats
  • Attack pattern consistent with generic automated attacks
  • No attribution to specific threat actor identified

4.3 Root Cause Analysis

• Time: 15:15 UTC (43 minutes after detection)
• Analysis:
  • Root Cause: Admin account email address publicly visible (website, public documents)
  • Contributing Factors:
    • Public email address increased attack surface
    • No rate limiting on authentication attempts (now implemented)
    • Account lockout threshold adequate (5 attempts)
• Recommendations:
  1. Implement rate limiting on authentication attempts
  2. Consider using non-public email addresses for admin accounts
  3. Enhance monitoring for brute force patterns

---

STEP 5: INCIDENT RESOLUTION (T+60 minutes)

5.1 Remediation Actions

• Time: 15:32 UTC (60 minutes after detection)
• Remediation:
  1. Rate Limiting: Rate limiting implemented on authentication server (max 5 attempts per 15 minutes per IP)
  2. Account Security: Admin account password reset (precautionary)
  3. Monitoring Enhancement: Enhanced monitoring rules added for brute force patterns
  4. Documentation: Incident fully documented in incident management system
• Status: All remediation actions completed

5.2 System Restoration

• Time: 15:35 UTC (63 minutes after detection)
• Restoration:
  1. Authentication server restored to full operation
  2. Network isolation removed (threat contained)
  3. Normal operations resumed
  4. Enhanced monitoring maintained
• Verification: System functionality verified, no impact on operations

5.3 Incident Closure

• Time: 15:40 UTC (68 minutes after detection)
• Closure Actions:
  1. Incident investigation completed
  2. Remediation actions implemented
  3. System restored to normal operations
  4. Incident report prepared
• Status: Incident resolved and closed
