CISO Assistant Basic Risk Assessment

Guide users through risk assessment setup using MCP server tools.

Prerequisites

1. Verify MCP server connectivity - Test with get_folders()
2. Backend must be running - CISO Assistant backend at configured URL
3. If MCP tools unavailable - Fall back to direct API calls (see bootstrap skill)

Key Principles

Always Pass folder_id for Scoping

When creating objects, always pass folder_id to scope lookups and avoid ambiguity errors when objects with the same name exist in different folders.

# CORRECT - folder_id scopes all lookups to ACME folder
create_risk_scenario(
  name="Ransomware on Customer Data",
  risk_assessment_id="ACME Risk Assessment 2025",
  folder_id="ACME",  # <- Scopes asset/threat lookups
  assets=["Customer Data"],
  threats=["Ransomware"],
  threat_library="urn:intuitem:risk:library:intuitem-common-catalog"
)

Always Use threat_library for Threat Lookups

Threats exist in multiple libraries (intuitem catalog, MITRE ATT&CK, etc.). Always specify the library:

threat_library="urn:intuitem:risk:library:intuitem-common-catalog"

Include Relevance in Scenario Descriptions

Always explain why a scenario matters for this specific organization:

"Ransomware attack encrypting customer data, leading to service disruption.
Relevance: GDPR breach implications with mandatory 72-hour notification
and potential fines up to 4% of annual revenue."

Workflow

Step 1: Choose Risk Approach

Ask the user which approach they prefer:

Approach	Description	Best For
Qualitative	Probability/impact scales (Low/Medium/High), 4x4 or 5x5 matrix	Initial assessments, stakeholder communication
Quantitative	Monetary values, Monte Carlo simulations, ALE calculations	Mature orgs, budget justification, executive reporting

Step 2: Gather Organizational Context

Ask about:

• Industry: healthcare, financial, tech/SaaS, retail, manufacturing, government
• Size: small (1-50), medium (50-500), large (500+)
• Region: for regulatory context (EU → GDPR, US healthcare → HIPAA, etc.)
• Cloud: AWS/Azure/GCP, SaaS-heavy or on-premise
• Compliance: specific requirements (HIPAA, PCI-DSS, GDPR, SOC2, ISO 27001)

Step 3: Create Domain and Perimeter

# 1. Create folder (domain)
create_folder(name="ACME", description="ACME Corp - Tech/SaaS, EU-based")

# 2. Create perimeter (assessment scope)
create_perimeter(name="ACME Platform", folder_id="ACME")

Step 4: Identify and Create Assets

Use references/typical-assets.md to suggest assets based on context.

Primary Assets (PR) - Business value:

• Customer/employee data, financial records, source code, API keys/secrets

Supporting Assets (SP) - Infrastructure:

• Cloud infrastructure, databases, CI/CD pipeline, email, endpoints

# Create assets - always pass folder_id
create_asset(name="Customer Data", description="Customer PII - GDPR relevant",
             asset_type="PR", folder_id="ACME")
create_asset(name="Production Database", description="Primary data storage",
             asset_type="SP", folder_id="ACME")

Step 5: Import Threat Catalog

# Import the intuitem common catalog (23 threats)
import_stored_library("urn:intuitem:risk:library:intuitem-common-catalog")

# Verify threats are available
get_threats(library="urn:intuitem:risk:library:intuitem-common-catalog")

Step 6: Generate Scenario Suggestions

Use the Threat-Asset Relevance Matrix in references/typical-assets.md to suggest the most relevant threat-asset combinations.

Naming convention: [Threat] on [Asset]

• "Ransomware on Customer Data"
• "Phishing targeting Employees"
• "Cloud Misconfiguration"

Present top 10-15 combinations and let user select which to create.

Step 7: Create Assessment Container

For Qualitative:

# Check available matrices
get_risk_matrices()

# Use matrix UUID to avoid ambiguity
create_risk_assessment(
  name="ACME Risk Assessment 2025",
  risk_matrix_id="<matrix-uuid>",  # Use UUID from get_risk_matrices()
  perimeter_id="ACME Platform",
  folder_id="ACME",
  status="in_progress"
)

For Quantitative:

create_quantitative_risk_study(
  name="ACME Quantitative Risk Study 2025",
  folder_id="ACME",
  distribution_model="lognormal_ci90"
)

Step 8: Create Risk Scenarios

For Qualitative:

create_risk_scenario(
  name="Ransomware on Customer Data",
  description="Ransomware attack encrypting customer data. Relevance: GDPR breach with 72-hour notification requirement.",
  risk_assessment_id="ACME Risk Assessment 2025",
  folder_id="ACME",  # CRITICAL: scope lookups
  assets=["Customer Data"],
  threats=["Ransomware"],
  threat_library="urn:intuitem:risk:library:intuitem-common-catalog"
)

For Quantitative:

create_quantitative_risk_scenario(
  name="Ransomware on Customer Data",
  description="Ransomware attack... Relevance: ...",
  quantitative_risk_study_id="ACME Quantitative Risk Study 2025",
  folder_id="ACME",
  assets=["Customer Data"],
  threats=["Ransomware"],
  threat_library="urn:intuitem:risk:library:intuitem-common-catalog"
)

Step 9: Summary and Next Steps

After creating scenarios, summarize and guide on next steps:

For Qualitative:

1. Rate probability and impact for each scenario in the UI
2. Identify and link existing controls
3. Plan additional controls for high-risk scenarios
4. Review risk matrix visualization

For Quantitative:

1. Create hypotheses with probability and impact bounds
2. Run Monte Carlo simulations
3. Set risk tolerance curve
4. Analyze portfolio-level risk
