- **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
