A guide to performing a cybersecurity risk assessment using NIST SP 800-30, a U.S. government method for documenting threats, weaknesses, likelihood, and impact.

In plain words

Use it to assess new or changed systems, support compliance work, and build or update an organization’s risk register.
Why use it?
It turns broad security concerns into a ranked list of risks with reasoning that leaders, auditors, and regulators can review.

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

conducting-cyber-risk-assessment-with-nist-800-30 scanned grade A with 0 findings 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 8d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/process.py), 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Conducting a Cyber Risk Assessment with NIST SP 800-30

When to Use

  • When the organization needs a real risk assessment — an analysis of specific threats, likelihoods, and impacts — rather than a maturity score against a framework. (Maturity tells you how mature your practices are; a risk assessment tells you what could hurt you and how badly.)
  • When another framework requires a documented risk analysis as a mandatory input: NIST CSF (ID.RA), ISO 27001 (Clause 6.1.2), NIST RMF / 800-37 (the Prepare and Select steps), SOC 2 (CC3), PCI DSS, or HIPAA (§164.308(a)(1)(ii)(A)).
  • When standing up or significantly changing a system and you must understand its risk before authorization or go-live.
  • When leadership asks for the organization's top risks, ranked, with a rationale they can defend to a board or regulator.
  • When building or refreshing an enterprise risk register.

Prerequisites

  • An inventory of in-scope assets, systems, and the information types they handle (system boundary defined).
  • Access to threat intelligence (internal incident history, sector ISAC feeds, MITRE ATT&CK) to ground threat-event likelihood in observed behavior.
  • Vulnerability data (scan results, pen-test findings, configuration/architecture review) for the in-scope systems.
  • Business context: which missions/processes the systems support, and what impact to confidentiality, integrity, or availability would mean in business terms.
  • Agreement on the risk model and scales before scoring, so results are comparable and repeatable (see references/standards.md).
  • Familiarity with the three-tier risk-management context from NIST SP 800-39 (organization, mission/business process, information system).

Workflow

NIST SP 800-30 Rev 1 defines four steps. Steps 1 and 4 bookend the assessment; Step 2 is the analytic core.

1. Prepare for the assessment

Define and document:

  • Purpose (e.g., support an authorization decision, inform control selection, satisfy ISO 6.1.2).
  • Scope — organizational tier (Tier 1/2/3), systems, and time horizon.
  • Assumptions and constraints (e.g., assume an external adversarial threat with moderate capability).
  • Information sources — threat, vulnerability, and impact inputs.
  • Risk model and analytic approach — the factors (threat source, threat event, vulnerability, likelihood, impact) and the scales (qualitative Very Low–Very High, or semi-quantitative 0–10). Lock these now.

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.
