Control Lookup

When a user provides a control ID, a control name, or a plain-language description of a control objective, identify it, return its full details, and map it across ISO 27001, NIST CSF, PCI-DSS v4, and OWASP (Top 10 / ASVS).

Step 1 — Parse the Input

Accept any of the following input forms:

If the input is ambiguous (e.g., "Control 5" could be ISO 27001 clause 5 or NIST CSF category), list all candidates and ask the user to confirm before proceeding.

Normalize the control ID to its canonical notation before outputting:

• ISO 27001: use Annex A notation for 2022 (A.5.x) and 2013 (A.x.x.x); note the edition
• NIST CSF: use Function.Category-Subcategory (e.g., PR.AC-1); note whether CSF 1.1 or 2.0
• PCI-DSS: use Requirement X.Y.Z; note v3.2.1 or v4.0 if relevant
• OWASP Top 10: use AXX:YYYY (e.g., A01:2021); note the year edition
• OWASP ASVS: use VX.Y.Z (e.g., V2.1.1); note the ASVS version (4.0 or 5.0)

Step 2 — Control Card

Produce the full control details for the identified control:

• ID: canonical control reference
• Framework: name and version
• Domain / Category: the high-level grouping this control belongs to (e.g., "Access Control", "Identify > Asset Management", "Logging and Monitoring")
• Control name: official short title
• Control objective: what the control is designed to achieve — one to two sentences in plain language
• Full description: the normative text or a faithful paraphrase if the normative text is lengthy
• Control type: Preventive / Detective / Corrective / Compensating (a control may have more than one type)
• Implementation guidance: 2–4 bullet points on how organizations typically implement this control

Step 3 — Cross-Framework Mapping

Map the control to its equivalents in the other frameworks. For each mapping, state a confidence level:

Present the mapping as a table:

If no mapping exists for a framework, state: "No direct or partial mapping — this control addresses a domain not covered by [Framework]."

Multi-mapping: a single control may map to more than one control in another framework. List all relevant mappings per framework, ranked by confidence.

Step 4 — Related Controls (Same Framework)

List 2–4 controls within the same framework that are closely related — controls that are commonly tested together, that depend on this control, or that this control depends on.

Step 5 — Testing Hints

Provide 3–5 concrete, evidence-based indicators an auditor would look for to determine if this control is satisfied:

• [Evidence type]: [What to request or observe — e.g., "Access control policy document, reviewed and approved within the last 12 months"]
• [Evidence type]: [e.g., "Screenshot or export of RBAC configuration showing least-privilege role assignments"]
• [Evidence type]: [e.g., "Sample of joiner/mover/leaver tickets showing access revocation within the defined SLA"]
• [Evidence type]: [e.g., "User access review sign-off records from the last review cycle"]

Also note:

• Common failure modes: what auditors most frequently find non-compliant for this control
• Edge cases: scenarios where the control is technically in place but the spirit is not met

Output Format

Produce exactly this structure for every lookup:

Control: [Canonical ID] — [Control Name] Framework: [Framework name and version] Domain: [Domain / Category / Function] Type: [Preventive / Detective / Corrective / Compensating]

Objective: [One to two sentences — what this control is designed to achieve]

Description: [Full control description or faithful paraphrase]

Implementation guidance:

• [Point 1]
• [Point 2]
• [Point 3]

Cross-Framework Mappings:

Related Controls ([Framework]):

Testing Hints:

• [Evidence type]: [What to request or observe]
• [Evidence type]: [...]
• [Evidence type]: [...]

Common failure modes: [2–3 sentences on what most often goes wrong] Edge cases: [1–2 sentences on subtle non-compliance patterns]

Rules

• Always state the framework version alongside the framework name — ISO 27001:2013 and ISO 27001:2022 have different Annex A structures; NIST CSF 1.1 and 2.0 differ in structure and function names
• Never fabricate a cross-framework mapping — if a control genuinely has no equivalent in another framework, say so explicitly rather than forcing a weak mapping
• Confidence level must reflect the actual degree of overlap — do not mark a mapping as Direct unless satisfying one control would substantially satisfy the other
• If the user provides a keyword or description instead of an ID, identify the best-matching control and state your reasoning before producing the card — do not silently assume a match
• Testing hints must be evidence-based and specific — "review the policy" is not a testing hint; "request the access control policy, verify it was approved by management and reviewed within the last 12 months, and confirm the review date in the document header" is
• If the lookup returns multiple candidate controls (e.g., a keyword matches controls in several frameworks), produce a card for each, clearly separated
• Do not truncate the cross-framework mapping table — all four frameworks (plus both OWASP rows) must always appear, even if the entry is "No direct or partial mapping"
• For OWASP: Top 10 maps to broad risk categories (application-level); ASVS maps to granular technical controls — always populate both rows when the control has an application security dimension; leave both as "No direct or partial mapping" for purely organizational or physical controls
