# Triaging Security Incidents with IR Playbooks

## When to Use
- New security alert received from SIEM, EDR, or other detection sources
- SOC analyst needs to determine if an alert is a true positive requiring response
- Incident needs severity classification and team assignment
- Multiple concurrent incidents require prioritization
- Automated triage rules need validation or tuning

## Prerequisites
- SIEM platform with alert correlation (Splunk, Elastic, QRadar, Sentinel)
- Incident response playbook library (by incident type)
- Severity classification matrix approved by CISO
- On-call rotation and escalation procedures
- Ticketing system for incident tracking (ServiceNow, Jira, TheHive)
- Threat intelligence feeds for IOC enrichment

## Workflow

### Step 1: Receive and Acknowledge Alert
```bash
# Query Splunk for new critical/high severity alerts
index=notable status=new severity IN ("critical","high")
| table _time, rule_name, src, dest, severity, description
| sort -_time

# Query TheHive for new cases
curl -s -H "Authorization: Bearer $THEHIVE_API_KEY" \
  "https://thehive.local/api/v1/query?name=list-alerts" \
  -H "Content-Type: application/json" \
  -d '{"query":[{"_name":"listAlert"},{"_name":"filter","_field":"status","_value":"New"}]}'

# Acknowledge alert in SIEM to prevent duplicate triage
curl -X POST "https://splunk.local:8089/services/notable_update" \
  -H "Authorization: Bearer $SPLUNK_TOKEN" \
  -d "ruleUIDs=$RULE_UID&status=1&comment=Triage+initiated+by+analyst"
```

### Step 2: Enrich Alert Data
```bash
# Enrich source IP with VirusTotal
curl -s "https://www.virustotal.com/api/v3/ip_addresses/$SRC_IP" \
  -H "x-apikey: YOUR_KEY | jq '.data.attributes.last_analysis_stats'

# Check IP reputation with AbuseIPDB
curl -s "https://api.abuseipdb.com/api/v2/check?ipAddress=$SRC_IP&maxAgeInDays=90" \
  -H "Key: $ABUSEIPDB_KEY" -H "Accept: application/json" | jq '.data'

# Enrich file hash with threat intelligence
curl -s "https://www.virustotal.com/api/v3/files/$FILE_HASH" \
  -H "x-apikey: YOUR_KEY | jq '.data.attributes.last_analysis_stats'

# Query internal asset database for affected systems
curl -s "https://cmdb.local/api/assets?ip=$DEST_IP" \
  -H "Authorization: Bearer $CMDB_TOKEN" | jq '.asset_criticality, .owner, .environment'
```

### Step 3: Classify Incident Type
```bash
# Map alert to incident category using playbook lookup
# Categories: Malware, Phishing, Unauthorized Access, Data Exfiltration,
# DoS/DDoS, Insider Threat, Ransomware, Account Compromise, Web Attack

# Check if alert matches known playbook trigger conditions
grep -i "$ALERT_SIGNATURE" /opt/ir/playbooks/trigger_conditions.yaml

# Determine incident type from MITRE ATT&CK technique
curl -s "https://attack.mitre.org/api/techniques/$TECHNIQUE_ID" | jq '.name, .tactic'
```

### Step 4: Assign Severity Level
```bash
# Severity matrix factors:
# 1. Asset criticality (Critical/High/Medium/Low)
# 2. Data sensitivity (PII/PHI/PCI/Confidential/Public)
# 3. Number of affected systems
# 4. Active vs historical threat
# 5. Confirmed vs suspected compromise

# Automated severity calculation
python3 -c "
severity_score = 0
# Asset criticality: Critical=4, High=3, Medium=2, Low=1
severity_score += 4  # Critical server
# Data sensitivity: PII/PHI=4, PCI=3, Confidential=2, Public=1
severity_score += 3  # PCI data
# Scope: Enterprise=4, Department=3, Single system=2, Single user=1
severity_score += 2  # Single system
# Threat status: Active=4, Recent=3, Historical=2, Potential=1
severity_score += 4  # Active threat

if severity_score >= 12: print('CRITICAL - P1')
elif severity_score >= 9: print('HIGH - P2')
elif severity_score >= 6: print('MEDIUM - P3')
else: print('LOW - P4')
print(f'Score: {severity_score}/16')
"
```

### Step 5: Select and Initiate Playbook
```bash
# Load appropriate playbook based on incident type
cat /opt/ir/playbooks/ransomware_playbook.yaml
cat /opt/ir/playbooks/phishing_playbook.yaml
cat /opt/ir/playbooks/unauthorized_access_playbook.yaml

# Create incident ticket in TheHive
curl -X POST "https://thehive.local/api/v1/case" \
  -H "Authorization: Bearer $THEHIVE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "title": "IR-2024-XXX: [Incident Type] - [Brief Description]",
    "description": "Triage summary and initial findings",
    "severity": 3,
    "tlp": 2,
    "pap": 2,
    "tags": ["ransomware", "triage-complete"],
    "customFields": {
      "playbook": {"string": "ransomware_v2"},
      "affected_systems": {"integer": 5}
    }
  }'
```

### Step 6: Assign Response Team
```bash
# Check on-call schedule
curl -s "https://pagerduty.com/api/v2/oncalls?schedule_ids[]=$SCHEDULE_ID" \
  -H "Authorization: Token token=$PD_TOKEN" | jq '.oncalls[].user.summary'

# Page incident responders based on severity
# P1/Critical: Page IR lead + senior analysts + CISO
# P2/High: Page IR lead + available analysts
# P3/Medium: Assign to next available analyst
# P4/Low: Queue for business hours processing

curl -X POST "https://events.pagerduty.com/v2/enqueue" \
  -H "Content-Type: application/json" \
  -d '{
    "routing_key": "'$PD_ROUTING_KEY'",
    "event_action": "trigger",
    "payload": {
      "summary": "P1 Security Incident: Ransomware detected on PROD-DB-01",
      "severity": "critical",
      "source": "SIEM-Splunk",
      "custom_details": {"incident_id": "IR-2024-042", "playbook": "ransomware_v2"}
    }
  }'
```

### Step 7: Document Triage Decision and Hand Off
```bash
# Update incident ticket with triage summary
curl -X PATCH "https://thehive.local/api/v1/case/$CASE_ID" \
  -H "Authorization: Bearer $THEHIVE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "status": "InProgress",
    "customFields": {
      "triage_analyst": {"string": "analyst_name"},
      "triage_time": {"date": '$(date +%s000)'},
      "severity_justification": {"string": "Critical asset + active threat + PCI data"}
    }
  }'
```

## Key Concepts

| Concept | Description |
|---------|-------------|
| True Positive | Alert correctly identifying a real security incident |
| False Positive | Alert incorrectly flagging benign activity as malicious |
| Severity Classification | Ranking incident priority based on impact and urgency |
| Playbook Selection | Choosing the appropriate response procedure based on incident type |
| IOC Enrichment | Adding context to indicators from threat intelligence sources |
| Escalation Threshold | Criteria triggering escalation to higher severity or management |
| Triage SLA | Time target for initial assessment (typically 15-30 min for critical) |

## Tools & Systems

| Tool | Purpose |
|------|---------|
| Splunk/Elastic/QRadar | SIEM alert correlation and querying |
| TheHive/SIRP | Incident case management and playbook tracking |
| VirusTotal/AbuseIPDB | IOC reputation and enrichment |
| PagerDuty/OpsGenie | On-call management and alerting |
| MITRE ATT&CK | Technique classification and mapping |
| Cortex XSOAR | SOAR platform for automated triage workflows |

## Common Scenarios

1. **Brute Force Alert**: Multiple failed logins from single IP. Enrich IP reputation, check geo-location, verify if account was compromised, assign P3 if unsuccessful.
2. **Malware Detection on Endpoint**: AV/EDR quarantined malware. Verify quarantine success, check for lateral movement, assign P2 if persistence detected.
3. **Suspicious Outbound Traffic**: Large data transfer to unknown external IP. Check if known cloud service, verify data classification, assign P1 if exfiltration confirmed.
4. **Phishing Email Reported**: User reports suspicious email. Extract IOCs, check if others received it, assign P2 if credentials were entered.
5. **Privilege Escalation**: User gained admin rights unexpectedly. Verify if authorized change, check for exploitation, assign P1 if unauthorized.

## Output Format
- Triage decision document with severity justification
- Incident ticket with assigned playbook and team
- IOC enrichment summary attached to case
- Escalation notification to appropriate stakeholders
- Initial timeline of events from alert data

# Incident Triage with IR Playbooks - Detailed Workflow

## Triage Decision Tree

```
Alert Received
    |
    v
Is alert from trusted/tuned detection rule?
    |-- No --> Check rule logic, verify data source --> Potential false positive
    |-- Yes --> Continue
    |
    v
Does alert match known false positive pattern?
    |-- Yes --> Document, close as false positive, tune rule
    |-- No --> Continue
    |
    v
Can indicator be enriched with external threat intel?
    |-- Yes --> Enrich with VT, AbuseIPDB, OTX --> Add context
    |-- No --> Continue with available data
    |
    v
What is the incident type?
    |-- Malware --> Malware playbook
    |-- Phishing --> Phishing playbook
    |-- Unauthorized Access --> Access compromise playbook
    |-- Data Exfiltration --> Data breach playbook
    |-- Ransomware --> Ransomware playbook
    |-- DoS/DDoS --> Availability playbook
    |-- Insider Threat --> Insider playbook
    |
    v
Assign severity based on:
    - Asset criticality x Threat level x Data sensitivity
    |
    v
Route to appropriate team with playbook
```

## Severity Assignment Matrix

### Impact Score (1-4)
| Score | Asset Criticality | Examples |
|-------|------------------|----------|
| 4 | Critical | Domain controllers, production databases, financial systems |
| 3 | High | Email servers, web applications, file servers |
| 2 | Medium | Development systems, internal tools |
| 1 | Low | Test systems, non-production workstations |

### Urgency Score (1-4)
| Score | Threat Status | Indicators |
|-------|-------------|------------|
| 4 | Active exploitation | Ongoing attack, real-time data loss |
| 3 | Confirmed compromise | Evidence of breach, but not active |
| 2 | Attempted attack | Blocked attack, no evidence of success |
| 1 | Reconnaissance | Scanning, probing, no exploitation attempt |

### Final Severity = Impact x Urgency
| Score Range | Severity | Response Time | Escalation |
|------------|----------|--------------|------------|
| 12-16 | P1 Critical | Immediate (15 min) | CISO + IR Lead + Senior Analysts |
| 8-11 | P2 High | 30 minutes | IR Lead + Available Analysts |
| 4-7 | P3 Medium | 2 hours | Next available analyst |
| 1-3 | P4 Low | 24 hours (business hours) | Queued for analyst review |

## Playbook Selection Guide

### By Alert Source
| Alert Source | Likely Playbook | Key Triage Actions |
|-------------|----------------|-------------------|
| EDR - Malware detection | Malware IR | Check quarantine status, verify family |
| Email gateway - Phishing | Phishing IR | Extract IOCs, check delivery scope |

| IDS/IPS - Exploit attempt | Vulnerability Exploitation | Verify patch status, check success |
| DLP - Data transfer | Data Exfiltration | Classify data, verify authorization |
| Cloud - Impossible travel | Cloud Account Compromise | Verify user, check API calls |

### By MITRE ATT&CK Tactic
| Tactic | Playbook | Priority |
|--------|----------|----------|
| Initial Access (TA0001) | Perimeter Breach | P1-P2 |
| Execution (TA0002) | Malware/Code Execution | P1-P2 |
| Persistence (TA0003) | Backdoor/Implant | P2 |
| Privilege Escalation (TA0004) | Privilege Escalation | P1 |
| Defense Evasion (TA0005) | Security Tool Bypass | P2 |

| Collection (TA0009) | Data Staging | P2 |
| Exfiltration (TA0010) | Data Breach | P1 |
| Impact (TA0040) | Ransomware/Destruction | P1 |

## IOC Enrichment Workflow

### Step 1: Automated Enrichment
1. Submit IPs to VirusTotal, AbuseIPDB, Shodan
2. Submit file hashes to VirusTotal, MalwareBazaar, Hybrid Analysis
3. Submit domains to URLScan.io, VirusTotal, PassiveTotal
4. Check against internal IOC database and watchlists

### Step 2: Context Addition
1. Look up asset in CMDB for criticality and owner
2. Check user in HR system for role and access level
3. Verify network zone and data classification
4. Cross-reference with recent threat intelligence reports

### Step 3: Correlation
1. Search SIEM for related alerts in past 72 hours
2. Check if same IOCs appeared in other incidents
3. Correlate with ongoing threat campaigns
4. Verify if alert is part of a larger attack chain

## Triage Documentation Requirements
1. Alert details (source, time, raw data)
2. Enrichment results (reputation scores, intelligence hits)
3. Classification decision (incident type, severity, justification)
4. Selected playbook and version
5. Assigned team/analyst
6. Initial timeline of observed events
7. Known affected assets and accounts
