security-operations

security-operations is a skill for Claude Code, Codex from williamzujkowski/standards. It costs 29 tokens per session (2,642 once invoked), scanned A, original, MIT.

A security-operations guide covering security monitoring, incident response, security information and event management (SIEM), and threat hunting.

In plain words
What is it for?
Use it to organise security operations centre work, investigate alerts, classify incidents, run threat hunts, and write SIEM queries.
Why use it?
It provides a structured way to detect attacks, assess alerts, contain incidents, restore services, and learn from what happened.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

security-operations scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/forensics-collection.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Asks for rootlowPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

sudo insmod lime-$(uname -r).ko "path=/tmp/memory.lime format=lime"

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Security Operations

Level 1: Quick Reference

Incident Response Lifecycle (NIST 800-61 Rev 2)

1. PREPARATION       - Policies, tools, training, communication plans
2. DETECTION         - SIEM alerts, log analysis, threat intelligence
3. CONTAINMENT       - Isolate, remove threat, restore operations
4. POST-INCIDENT     - Lessons learned, documentation, improvement

SOC Tiers

Tier Role Responsibilities
T1 Alert Triage Monitor SIEM, validate alerts, categorize, escalate
T2 Incident Response Investigation, forensics, containment
T3 Threat Hunting Proactive hunting, APT detection, automation

Incident Severity Classification

Severity Impact Response Time Escalation
Critical Business-critical compromised, active exfiltration <15 min CISO, Legal
High Multiple systems, potential breach <1 hour Tier 3, Management
Medium Single system, contained threat <4 hours Tier 2
Low Failed attack, no impact <24 hours Tier 1

Essential SIEM Queries

Failed Login Attempts (Splunk):

index=security sourcetype=auth action=failure
| stats count by user, src_ip
| where count > 5

Privilege Escalation (Azure Sentinel):

SecurityEvent
| where EventID == 4672
| where AccountType == "User"
| summarize count() by Account, Computer

Security Metrics Targets

  • MTTD (Mean Time To Detect): <1 hour for critical
  • MTTR (Mean Time To Respond): <4 hours for critical
  • False Positive Rate: <10%

Level 2: Implementation Guide

Full Examples: See REFERENCE.md for complete code samples, detailed configurations, and production-ready implementations.

SOC Team Structure

Core Roles:

  • SOC Manager: Strategic planning, metrics reporting, policy development
  • Tier 1 Analyst: 24/7 SIEM monitoring, alert validation (NIST SI-4)
  • Tier 2 Analyst: Deep investigation, forensics, containment (NIST IR-4, IR-6)
  • Tier 3 Analyst: Threat hunting, APT detection, tool development (NIST IR-5, AU-6)
  • Incident Commander: Major incident coordination, stakeholder communication

What ships with it

7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

security-operations is a skill published in the GitHub repository williamzujkowski/standards (18 stars, last pushed 1mo ago), licensed MIT. It adds 29 tokens to every session and 2,642 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-29.
