## What it does

The skill structures the operations layer above SIEM detection and incident triage. It outlines workflows across three modes: building a new capability, running daily alert queues, and improving broken processes. Based on 168 hours of weekly coverage, it calculates a baseline of 5 analysts without overlap and 6 to 7 to handle burnout and time off.

Guidance includes a three-tier model spanning initial triage, investigation, and engineering. For teams with 4 or fewer analysts, the skill explicitly advises against artificial tiering, collapsing Tier 1 and Tier 2 tasks into combined roles. It also provides markdown runbook templates, shift handoff checklists, and strict escalation thresholds.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add briiirussell/cybersecurity-skills --skill soc-operations -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/soc-operations/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/soc-operations/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add briiirussell/cybersecurity-skills --skill soc-operations -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/soc-operations/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add briiirussell/cybersecurity-skills --skill soc-operations -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/soc-operations/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install briiirussell/cybersecurity-skills soc-operations
```

2. **Manually: put the files in place**
- File: `.github/skills/soc-operations/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add briiirussell/cybersecurity-skills --skill soc-operations -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/briiirussell/cybersecurity-skills --path skills/soc-operations
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/soc-operations/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add briiirussell/cybersecurity-skills --skill soc-operations -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/briiirussell/cybersecurity-skills/tree/HEAD/skills/soc-operations/SKILL.md

## When to use it
- calculate staffing requirements for 24/7 SOC coverage
- structure standard runbooks for recurring detection alerts
- establish explicit escalation criteria between analyst tiers
- run a shift handoff checklist to prevent missed overnight incidents

## Example prompts
- Draft a runbook for recurring LSASS credential dumping alerts.
- Calculate our 24/7 shift staffing needs and identify when to use an MSSP.
- Define escalation rules for moving an incident from Tier 1 triage to Tier 2.

# SOC Operations — Building and Running a Security Operations Center

The operations layer above `siem-detection` (engineering rules) and `incident-triage` (response). This skill is about the *people and process* of running 24/7 alert triage — alert prioritization, runbook authoring, escalation, on-call hygiene, MTTD / MTTR, and the slow drift toward alert fatigue that kills SOCs.

Three modes:
- **Build** — designing a SOC from scratch (small org standing up its first IR capability, or MSSP onboarding)
- **Run** — daily operations for an existing SOC
- **Improve** — analyzing an existing SOC's metrics and fixing the broken parts

Cross-references: `siem-detection` (the rules that feed alerts to the SOC), `incident-triage` (the playbook for confirmed incidents), `threat-hunting` (proactive work between alert triage), `breach-patterns` (what attacks the SOC should be ready for).

## Mode 1 — Build a SOC

### Decision: in-house, MSSP, or hybrid?

| Model | When it fits | Pitfalls |
|---|---|---|
| Fully in-house | Mature security org, ≥ 5 dedicated analysts, regulated industry | Hard to staff 24/7 with under 8 people; on-call burnout |
| Fully outsourced (MSSP) | Smaller orgs, regulated requirements without internal staffing | MSSP context drift — they don't know your business; alert tuning slow |
| Hybrid (MSSP Tier 1, in-house Tier 2+) | Most common for growth-stage companies | Handoff complexity, "MSSP filtered it but didn't tell us" gaps |

### Staffing model

For 24/7 in-house coverage, the math:

- 24 × 7 = 168 hours per week of coverage needed
- One analyst at 40 hours/week (= 160 hr/yr × 50 weeks ≈ 8000 hr/yr - PTO - training ≈ 1700 productive hours)
- Minimum 5 analysts for true 24/7 if no overlap; realistic minimum 6–7 to handle PTO and burnout
- Below 6 — consider MSSP for off-hours coverage; the burnout cost of "always on" is real

### Analyst tiering

Standard tier model (adjust to taste):

- **Tier 1 — Triage:** initial alert review. Closes false positives with notes. Escalates real findings to Tier 2. Typically follows runbooks; deviates with documentation.
