## Core Capabilities

### 1. Alert Triage Automation

**When the user provides SIEM alerts and asks to triage:**

**Triage Decision Framework:**

```
Step 1: Parse alert data
  - Source: SIEM, EDR, WAF, IDS, email security, cloud audit logs
  - Extract: timestamp, source IP, destination, user, process, alert type

Step 2: Asset criticality lookup
  - Is the asset business-critical? (production DB, domain controller, payment system)
  - Is the user privileged? (admin, developer, finance)
  - What is the asset's network exposure?

Step 3: Threat context enrichment
  - IP reputation: Check against blocklists (AbuseIPDB, VirusTotal, Shodan)
  - Hash reputation: VirusTotal lookup for file hashes
  - Domain reputation: Phishtank, URLhaus, MX Toolbox
  - User risk score: Recent activity anomalies, recent password resets

Step 4: Apply triage matrix
```

**Alert Triage Matrix:**

| Alert Confidence | Asset Criticality | Recommended Action | SLA |
|----------------|-------------------|--------------------|-----|
| High | Critical | Immediate escalation to Tier 2/3 — declare incident | 15 min |
| High | High | Tier 1 priority investigation | 30 min |
| High | Medium | Tier 1 standard investigation | 1 hour |
| High | Low | Tier 1 standard queue | 4 hours |
| Medium | Critical | Tier 1 priority investigation | 30 min |
| Medium | High | Tier 1 standard investigation | 2 hours |
| Medium | Low | Standard queue, investigate if pattern emerges | 8 hours |
| Low | Any | Auto-close with documentation and note | 24 hours |

**Triage Analysis Output Format:**
```markdown
## Alert Triage Summary

**Alert ID:** [ID]
**Alert Type:** [Type — e.g., Brute Force Login]

python scripts/alert_triager.py --alerts siem_export.csv --playbook default --auto-assign
```

### 2. Incident Playbook Creation

**When the user asks to create a SOC playbook:**

**Playbook YAML Template (SOAR-compatible):**

```yaml

### 3. Escalation Workflow Design

**When the user asks to design an escalation workflow:**

```markdown
## CSOC Escalation Workflow

### Severity Definitions
| Level | CVSS / Impact | Response Time | Team |
|-------|--------------|---------------|------|
| P1 — Critical | 9.0–10.0 or system breach | 15 minutes | Tier 3 + IR Lead + Management |
| P2 — High | 7.0–8.9 or data at risk | 30 minutes | Tier 2 + Tier 3 standby |
| P3 — Medium | 4.0–6.9 | 2 hours | Tier 1 → Tier 2 if unresolved |
| P4 — Low | 0.1–3.9 | 8 hours | Tier 1 |

### Escalation Paths
```
P1 Incident:
  Tier 1 Analyst → [immediately] → Tier 3 Lead (call)
  Tier 3 Lead → [within 5 min] → SOC Manager (call)
  SOC Manager → [within 15 min] → CISO + Legal (if data breach)

P2 Incident:
  Tier 1 Analyst → [after 30 min unresolved] → Tier 2 Analyst (ticket escalation)
  Tier 2 Analyst → [after 2 hours unresolved] → Tier 3 Lead (chat notification)

Out-of-hours escalation:
  On-call Tier 2 via PagerDuty → 15 min acknowledge → escalate to Tier 3
```

### Notification Templates

**Slack Critical Alert Template:**
```
🚨 *P1 SECURITY INCIDENT DECLARED* 🚨
*Type:* {{incident_type}}
*Affected:* {{affected_systems}}
*Time Detected:* {{detection_time}} UTC
*IR Lead:* @{{ir_lead}}
*Bridge:* [link to war room]
*Ticket:* {{ticket_id}}
ACTION REQUIRED: All IR team members join the bridge now.
```

**Email Escalation Template:**
```
Subject: [P{{severity}}] Security Incident — {{incident_type}} — {{ticket_id}}

CSOC has declared a security incident.

Incident ID: {{ticket_id}}
Type: {{incident_type}}
Severity: {{severity}}
Detected: {{detection_time}} UTC
Current Status: {{status}}
Affected Systems: {{affected_systems}}

Current Actions:
{{current_actions}}

Required Actions:
{{required_actions}}

Next Update: {{next_update_time}}

SOC Contact: soc@company.com | +1-555-SOC-HELP
```

### 4. Shift Handover Report Generation

**When the user asks to generate a shift report:**

```bash
python scripts/alert_triager.py --report shift --shift night --date 2025-05-28 --output report.md
```

**Shift Handover Report Template:**
```markdown
# CSOC Shift Handover Report
**Shift:** Night (22:00–06:00 UTC)
**Date:** 2025-05-28
**Outgoing Analyst:** [Name]
**Incoming Analyst:** [Name]

---

## Shift Summary
| Metric | Count |
|--------|-------|
| Total Alerts | 142 |
| True Positives | 8 |
| False Positives | 118 |
| Undetermined | 16 |
| Incidents Declared | 2 |
| Average Triage Time | 12 minutes |
| SLA Compliance | 94.4% |

## Open Incidents (Require Immediate Attention)
| ID | Type | Severity | Status | Owner | Next Action |
|----|------|----------|--------|-------|-------------|
| INC-2025-089 | Phishing Campaign | P2 | Investigating | [Name] | Awaiting EDR report |
| INC-2025-090 | Suspicious Login | P3 | Monitoring | [Name] | 24h watch, escalate if repeat |

## Alerts Closed This Shift
- 118 False Positives auto-closed (brute force from known scanners, pen test activity)
- 12 True Positives resolved (malware blocked by AV, no further action needed)

## Ongoing Watches (No Action Yet Required)
- Increased scan activity from 198.51.100.0/24 — monitoring trend
- User john.doe@company.com multiple failed VPN logins — watching for successful auth

## Tool/System Issues
- Splunk indexer latency 45 min this shift — events delayed, may affect investigation timing
- EDR console intermittently slow — reported to IT ops (ticket: OPS-4421)

## Recommended Actions for Next Shift
1. Follow up on INC-2025-089: EDR report expected from endpoint team by 08:00
2. Review john.doe@company.com VPN activity — if successful login from new location, triage
3. Watch for continued scanning from 198.51.100.x block
```

### 5. SOC Metrics & KPI Tracking

**When the user asks about SOC metrics or KPI analysis:**

**Key SOC Metrics:**

| Metric | Formula | Target |
|--------|---------|--------|
| **MTTD** (Mean Time to Detect) | Avg(detection_time − attack_start_time) |  95% |
| **Analyst Capacity** | Alerts handled per analyst per shift | Track trend |
| **Escalation Rate** | Escalated to Tier 2/3 / Total Tickets | < 20% |

**Monthly KPI Dashboard Template:**
```markdown
## SOC Monthly Metrics Report — May 2025

### Volume
- Total Alerts: 4,215
- True Positives: 287 (6.8%)
- False Positives: 3,928 (93.2%)
- Incidents Declared: 14

### Response Performance
- MTTD: 23 minutes (↓ from 31 min last month) ✓
- MTTR: 3.2 hours (↑ from 2.8 hours) ⚠
- SLA Compliance: 96.1% ✓

### Top Alert Categories
1. Brute Force Attempts: 1,842 (94% FP from scanner IPs)
2. Malware Detected: 412 (78% TP)
3. Data Loss Prevention: 287 (32% TP)
4. Privilege Escalation: 156 (65% TP)

### Recommendations
1. Allowlist known scanner IPs to reduce brute force FP volume (-40% alert load)
2. MTTR increased due to EDR tool latency — investigate performance

## v3.0 Enhancements (2026 Update)

**AI-augmented, metrics-driven SOC:**

- **AI-assisted triage** — use the LLM to summarize alerts, cluster duplicates, enrich with threat intel, and draft the analyst's first-pass disposition — with a human-in-the-loop gate before any containment action (see Skill 16 for safe agent design).
- **Detection-as-code & SOAR** — playbooks and detections in version control with tests; automated enrichment (WHOIS, VT, GeoIP, asset/identity context) before a human sees the ticket.
- **Alert tuning loop** — track false-positive rate per rule; auto-propose suppression/tuning when FP rate exceeds threshold to fight alert fatigue.
- **MITRE D3FEND** — map each playbook's containment/eradication steps to D3FEND countermeasures, complementing ATT&CK coverage.
- **Metrics** — report MTTD, MTTA, MTTR, dwell time, and detection coverage by ATT&CK tactic; trend them across shifts.

**Precision rule:** every automated action is logged, reversible where possible, and gated by severity; irreversible actions require explicit human approval.
