Core Risk Entities

1. Risk Entity

Location: src/Entity/Risk.php

Key Fields:

class Risk
{
    private ?int $id;
    private string $name;                    // Risk title
    private string $description;             // Detailed description

    private int $inherentImpact;            // 1-5 (Negligible to Critical)
    private int $inherentLikelihood;        // 1-5 (Rare to Almost Certain)
    private int $inherentRisk;              // inherentImpact × inherentLikelihood (1-25)
    private int $residualImpact;            // After controls
    private int $residualLikelihood;        // After controls
    private int $residualRisk;              // residualImpact × residualLikelihood

    private ?bool $requiresDpia;             // GDPR Data Protection Impact Assessment flag

    // Relationships
    private Collection $assets;              // Asset[] - ManyToMany
    private Collection $controls;            // Control[] - ManyToMany
    private Collection $riskTreatmentPlans;  // RiskTreatmentPlan[] - OneToMany
    private Collection $riskAcceptances;     // RiskAcceptance[] - OneToMany
    private ?BusinessProcess $businessProcess; // ManyToOne
    private Collection $incidents;           // Incident[] - ManyToMany (validation)

    // Multi-tenancy
    private ?Tenant $tenant;
    private ?int $tenantId;
}

Risk Matrix (5×5):

Impact →        1           2           3           4           5
Likelihood ↓   Negligible  Minor       Moderate    Major       Critical
---------------------------------------------------------------------------
5 (Almost      5 (Medium)  10 (High)   15 (High)   20 (Critical) 25 (Critical)
  Certain)
4 (Likely)     4 (Low)     8 (Medium)  12 (High)   16 (High)    20 (Critical)
3 (Possible)   3 (Low)     6 (Medium)  9 (Medium)  12 (High)    15 (High)
2 (Unlikely)   2 (Low)     4 (Low)     6 (Medium)  8 (Medium)   10 (High)
1 (Rare)       1 (Low)     2 (Low)     3 (Low)     4 (Low)      5 (Medium)

Risk Levels:

• 1-3: Low (Green) - Accept, monitor
• 4-9: Medium (Yellow) - Reduce likelihood or impact
• 10-15: High (Orange) - Immediate treatment required
• 16-25: Critical (Red) - Urgent treatment, management escalation

2. RiskTreatmentPlan Entity

Location: src/Entity/RiskTreatmentPlan.php

Purpose: Documents how risks will be treated

Key Fields:

class RiskTreatmentPlan
{
    private ?int $id;
    private string $strategy;                // Avoid, Reduce, Transfer, Accept
    private string $description;             // Treatment actions
    private ?\DateTimeInterface $targetDate; // Implementation deadline
    private ?string $responsiblePerson;      // Owner of treatment
    private string $status;                  // Planned, In_Progress, Completed, Cancelled
    private ?int $estimatedCost;            // Budget required
    private ?int $priority;                  // 1 (Low) to 5 (Critical)

    private Collection $controls;            // Control[] - ManyToMany (controls to implement)
}

Treatment Strategies (ISO 27005):

1. Avoid - Eliminate activity causing risk (e.g., discontinue service)
2. Reduce - Implement controls to lower impact/likelihood
3. Transfer - Shift risk to third party (insurance, outsourcing)
4. Accept - Acknowledge risk, no treatment (requires formal acceptance)

3. RiskAppetite Entity

Purpose: Defines organization's willingness to accept risk (ISO 31000 concept)

Key Fields:

class RiskAppetite
{
    private ?int $id;

    private int $maxAcceptableRisk;         // 1-25 (threshold on risk matrix)
    private ?string $rationale;              // Why this threshold?
    private string $status;                  // Active, Under_Review, Archived
    private ?\DateTimeInterface $approvedDate;
    private ?string $approvedBy;             // Senior management
    private ?\DateTimeInterface $reviewDate; // Next review
    private ?string $kris;                   // Key Risk Indicators (JSON)

    // Relationships
    private ?Tenant $tenant;
}

Example Thresholds:

• Financial: Max 12 (High) - Business can tolerate up to 12 on risk matrix
• Compliance: Max 6 (Medium) - Low tolerance for regulatory violations
• Operational: Max 9 (Medium) - Moderate tolerance for process disruptions
• Reputational: Max 4 (Low) - Very low tolerance for brand damage

4. RiskAcceptance Entity

Location: src/Entity/RiskAcceptance.php

Purpose: Formal documentation of accepted risks (ISO 27005 requirement)

Key Fields:

class RiskAcceptance
{
    private ?int $id;
    private ?Risk $risk;                     // ManyToOne

    private ?string $acceptedBy;             // Name/role of acceptor
    private ?\DateTimeInterface $acceptedDate;
    private ?\DateTimeInterface $expiryDate; // When to re-review
    private string $status;                  // Pending, Approved, Rejected, Expired
    private ?string $conditions;             // Conditions for acceptance
    private ?int $approvalLevel;             // 1 (Manager) to 3 (Board)

    // Relationships
    private ?Tenant $tenant;
}

Approval Levels:

• Level 1 (Manager): Residual risk 1-6 (Low to Medium)
• Level 2 (Senior Management): Residual risk 7-12 (Medium to High)
• Level 3 (Board/Executive): Residual risk 13-25 (High to Critical)

Data Reuse Principles ⭐

Overview

The application implements extensive Data Reuse patterns to optimize risk management workflows and save time. Instead of manually entering the same information multiple times, the system automatically leverages existing data from Assets, Incidents, Controls, and Business Processes.

1. Asset → Risk Integration

Pattern: Asset monetary value, CIA ratings, and metadata inform risk impact calculations

Implementation:

• Risk entity has ManyToMany relationship with Asset
• RiskImpactCalculatorService reads Asset.monetaryValue to suggest financial impact
• AssetRiskCalculatorService aggregates CIA ratings (Confidentiality, Integrity, Availability) to calculate overall asset risk

Workflow Optimization:

Traditional Approach:
1. Create Asset (5 min)
2. Manually calculate financial impact of loss (10 min)
3. Create Risk with manual impact entry (5 min)
Total: 20 minutes

Data Reuse Approach:
1. Create Asset with monetary value (5 min)
2. Link Asset to Risk (30 sec)
3. System auto-calculates impact from asset value (instant)
Total: 5.5 minutes → 72% time savings

Example:

// Asset exists with monetaryValue = €100,000
$fileServer = $assetRepository->find(42);

// Create risk and link asset
$risk = new Risk();
$risk->setName('Ransomware Attack');
$risk->addAsset($fileServer);

// System automatically suggests:
// - financialImpact: €100,000 (from asset)
// - inherentImpact: 5 (Critical, based on value threshold)
// - complianceImpact: 'GDPR Art. 32' (if asset contains personal data)

2. Incident → Risk Integration

Pattern: Historical incidents validate and adjust risk probability assessments

Implementation:

• Risk entity has ManyToMany relationship with Incident
• RiskProbabilityAdjustmentService analyzes incident frequency to calibrate likelihood
• Incident severity and business impact feed into risk impact validation

Workflow Optimization:

Traditional Approach:
1. Risk Manager estimates likelihood based on intuition (15 min)
2. Management questions the estimate (5 min)
3. Manually search for similar past incidents (30 min)
4. Adjust likelihood based on findings (5 min)
Total: 55 minutes

Data Reuse Approach:
1. Link related incidents to risk (2 min)
2. System auto-analyzes frequency and suggests likelihood (instant)
3. Present data-backed probability to management (2 min)
Total: 4 minutes → 93% time savings

Example:

// 3 phishing incidents in past 12 months
$risk->addIncident($incident1);  // 3 months ago
$risk->addIncident($incident2);  // 7 months ago
$risk->addIncident($incident3);  // 11 months ago

// System automatically calculates:
// - Frequency: 3 incidents / 12 months = 25% annual probability
// - Suggested likelihood: 4 (Likely) instead of initial estimate 2 (Unlikely)
// - Trend: Increasing (incident gaps decreasing: 8→4→3 months)
// - Recommendation: "Likelihood should be raised to 4 based on incident history"

3. Control → Risk Integration

Pattern: Implemented controls reduce residual risk through effectiveness calculation

Implementation:

• Risk entity has ManyToMany relationship with Control (ISO 27001 Annex A)
• RiskService->calculateResidualRisk() applies control effectiveness percentage
• RiskTreatmentPlanService->suggestControls() recommends relevant Annex A controls

Workflow Optimization:

Traditional Approach:
1. Assess inherent risk (10 min)
2. Manually list potential controls from ISO 27001 (20 min)
3. Estimate residual risk after controls (15 min)
4. Document control selection justification (10 min)
Total: 55 minutes

Data Reuse Approach:
1. Assess inherent risk (10 min)
2. System suggests relevant ISO 27001 controls (instant)
3. Select controls, system auto-calculates residual risk (2 min)
4. Document justification with pre-filled suggestions (3 min)
Total: 15 minutes → 73% time savings

Example:

$risk->setInherentImpact(4);
$risk->setInherentLikelihood(4);
$risk->setInherentRisk(16);  // Critical

// Link ISO 27001 controls
$controlBackup = $controlRepository->findByAnnexId('A.8.13');  // Information backup
$controlBackup->setImplementationStatus('Implemented');
$controlBackup->setEffectiveness(80);  // 80% effective

$controlAccessControl = $controlRepository->findByAnnexId('A.5.15');  // Access control
$controlAccessControl->setImplementationStatus('Implemented');
$controlAccessControl->setEffectiveness(70);

$risk->addControl($controlBackup);
$risk->addControl($controlAccessControl);

// System automatically calculates residual risk:
// Combined effectiveness = (80% + 70%) / 2 = 75%
// Residual impact = 4 × (1 - 0.75) = 1 (Negligible)
// Residual risk = 1 × 4 = 4 (Low) ✓ Treatment successful!

4. BusinessProcess → Risk Integration

Pattern: Business process criticality (from BIA) informs risk priority

Implementation:

• Risk entity has ManyToOne relationship with BusinessProcess
• Business process RTO/MTPD/criticality influence risk treatment urgency
• Integration with BCM (ISO 22301) for continuity planning

Workflow Optimization:

Traditional Approach:
1. Perform BIA for business process (60 min)
2. Separately assess risks to that process (45 min)
3. Manually determine which risks threaten RTO/MTPD (20 min)
4. Prioritize risks based on business criticality (15 min)
Total: 140 minutes (2h 20min)

Data Reuse Approach:
1. Perform BIA (already done in BCM module) (0 min)
2. Link business process to risks (2 min)
3. System auto-prioritizes based on RTO/MTPD/criticality (instant)
4. Review prioritization (5 min)
Total: 7 minutes → 95% time savings

Example:

// Business process from BIA
$payrollProcess = $businessProcessRepository->find(15);
$payrollProcess->setCriticalityLevel(5);  // Critical
$payrollProcess->setRto(4);  // 4 hours
$payrollProcess->setMtpd(24);  // 24 hours

// Link risk to process
$risk->setBusinessProcess($payrollProcess);
$risk->setInherentRisk(12);  // High

// System automatically:
// 1. Raises priority to 5 (Critical) due to process criticality
// 2. Sets treatment deadline = RTO (4 hours from incident)
// 3. Suggests treatment strategy = 'Reduce' (due to high criticality)
// 4. Flags for senior management review (criticality level 5)
// 5. Creates link to BC Plan for this process (ISO 22301 integration)

5. Cross-Entity Risk Intelligence

Pattern: Aggregate data from multiple sources for comprehensive risk view

Services:

• AssetRiskCalculatorService - Combines Assets + Risks + Incidents + Controls
• RiskDashboardService - Real-time KPIs across all entities
• RiskAppetitePrioritizationService - Compares risks to appetite thresholds

Comprehensive Risk Scoring:

$assetRiskCalculatorService->calculateAssetRisk($criticalServer);

// Combines data from:
// 1. Asset CIA ratings (C=5, I=5, A=5) → Base score: 50
// 2. Active risks (3 risks: 12, 15, 8) → Adds 35 points
// 3. Incident history (2 incidents this year) → Adds 10 points
// 4. Control coverage (12/15 controls implemented) → Reduces by 20%
// 5. Business process criticality (Level 5) → Adds 10 points
//
// Final Score: 68/100 (High Risk)
// Recommendation: "Implement 3 missing controls, review in 30 days"

ISO 27005 Compliance Guidance

Risk Management Process (ISO 27005 Clauses)

Clause 6.2: Context Establishment

Requirement: Define risk management scope, criteria, organization

Implementation in Application:

1. Tenant-Level Risk Appetite - Define via RiskAppetite entity

   • Navigate: Admin → Risk Management → Risk Appetite
   • Set thresholds per category (Strategic, Operational, Financial, etc.)
   • Obtain senior management approval

2. Risk Criteria - 5×5 risk matrix embedded in Risk entity

   • Impact scale: 1 (Negligible) to 5 (Critical)
   • Likelihood scale: 1 (Rare) to 5 (Almost Certain)
   • Risk levels: Low (1-3), Medium (4-9), High (10-15), Critical (16-25)

3. Asset Identification - Link via Risk->assets relationship

   • Use Data Reuse: Leverage existing Asset entity (already classified)
   • Automatic CIA rating inheritance

Compliance Check:

✅ Risk appetite defined and approved?
✅ Risk matrix criteria documented?
✅ Asset inventory complete and classified?
✅ Risk owner roles assigned?

Clause 6.3: Risk Assessment

6.3.1: Risk Identification

Requirement: Identify risks to CIA of information assets

Implementation:

// Create risk with threat and vulnerability
$risk = new Risk();
$risk->setName('Unauthorized Access to Customer Database');
$risk->setThreatSource('External');  // ISO 27005: External actor
$risk->setVulnerability('Weak password policy');  // ISO 27005: Vulnerability
$risk->setCategory('Technical');

// Link affected assets (Data Reuse)
$risk->addAsset($customerDatabase);

Threat Sources (ISO 27005 Table 2):

• Human (Accidental, Deliberate)
• Natural (Fire, Flood, Earthquake)
• Environmental (Power failure, HVAC failure)
• Technical (Hardware failure, Software bug)

6.3.2: Risk Analysis

Requirement: Assess impact and likelihood

Implementation:

// Impact assessment (ISO 27005 Annex E)
$riskImpactCalculator->suggestImpactLevel($customerDatabase, 'Confidentiality');
// Returns: 5 (Critical) - based on GDPR personal data, 50,000 records

$risk->setInherentImpact(5);
$risk->setFinancialImpact(500000);  // GDPR Art. 83: €10M or 2% revenue
$risk->setComplianceImpact('GDPR Art. 32 (Security of processing), Art. 33 (Breach notification)');

// Likelihood assessment (ISO 27005 Annex E)
$riskProbabilityAdjustment->suggestLikelihood('External_Attack', $tenant);
// Analyzes incident history: 2 similar incidents in past year
// Returns: 3 (Possible)

$risk->setInherentLikelihood(3);
$risk->setLikelihoodJustification('Similar attacks occurred 2x in past 12 months');

// Calculate inherent risk
$inherentRisk = $riskService->calculateInherentRisk(5, 3);  // 15 (High)

6.3.3: Risk Evaluation

Requirement: Compare risk against acceptance criteria

Implementation:

// Check against risk appetite
$appetiteCheck = $riskAppetitePrioritization->checkAgainstAppetite($risk);

if ($appetiteCheck['exceeds']) {
    // Risk 15 exceeds appetite threshold 12 → Treatment required
    $risk->setTreatmentStrategy('Reduce');
    $risk->setPriority(5);  // Critical

    // Auto-generate treatment plan
    $plan = $treatmentPlanService->createTreatmentPlan($risk, [
        'strategy' => 'Reduce',
        'targetDate' => new \DateTime('+90 days'),
        'responsiblePerson' => $risk->getRiskOwner(),
    ]);
}

Compliance Check:

✅ Impact analyzed for Financial, Operational, Legal, Reputational?
✅ Likelihood based on data (incident history, threat intelligence)?
✅ Inherent risk calculated and documented?
✅ Risk compared against appetite?

Clause 6.4: Risk Treatment

6.4.1: Risk Treatment Option Selection

Requirement: Select treatment strategy (Modify, Retain, Avoid, Share)

Implementation:

// ISO 27005 treatment options
$plan->setStrategy('Reduce');  // Modify risk
// OR
$plan->setStrategy('Accept');  // Retain risk (requires formal acceptance)
// OR
$plan->setStrategy('Avoid');   // Avoid risk (eliminate activity)
// OR
$plan->setStrategy('Transfer'); // Share risk (insurance, outsourcing)

6.4.2: Risk Treatment Plan

Requirement: Document treatment actions, resources, timelines

Implementation:

$plan = new RiskTreatmentPlan();
$plan->setRisk($risk);
$plan->setStrategy('Reduce');
$plan->setDescription('Implement MFA, strong password policy (12+ chars), regular access review');
$plan->setTargetDate(new \DateTime('+60 days'));
$plan->setResponsiblePerson('IT Security Manager');
$plan->setEstimatedCost(15000);  // MFA solution cost
$plan->setVerificationMethod('Penetration test after implementation');

// Link ISO 27001 controls (Data Reuse)
$controlMFA = $controlRepository->findByAnnexId('A.5.17');  // Authentication information
$controlPassword = $controlRepository->findByAnnexId('A.5.18');  // Access rights
$plan->addControl($controlMFA);
$plan->addControl($controlPassword);

$plan->setStatus('Planned');

6.4.3: Residual Risk Assessment

Requirement: Calculate risk after treatment

Implementation:

// Update control effectiveness
$controlMFA->setEffectiveness(90);  // MFA is highly effective
$controlPassword->setEffectiveness(70);

// Calculate residual risk (automatic)
$residualRisk = $riskService->calculateResidualRisk($risk);
// Residual likelihood = 3 × (1 - 0.80 average effectiveness) = 0.6 → 1 (Rare)
// Residual risk = 5 × 1 = 5 (Medium) ✓ Within appetite (threshold 12)

$risk->setResidualImpact(5);  // Impact unchanged
$risk->setResidualLikelihood(1);  // Likelihood reduced
$risk->setResidualRisk(5);

6.4.4: Risk Acceptance

Requirement: Formal acceptance by risk owner

Implementation:

if ($risk->getTreatmentStrategy() === 'Accept') {
    // Create formal acceptance (ISO 27005 requirement)
    $acceptance = $acceptanceWorkflowService->createAcceptanceRequest($risk,
        'Residual risk 5 is below appetite threshold 12. Cost of further treatment (€50k) exceeds potential loss (€20k).'
    );

    // Determine approval level based on residual risk
    $approvalLevel = $acceptanceWorkflowService->determineApprovalLevel($risk);
    // Residual risk 5 → Approval Level 1 (Manager sufficient)

    $acceptance->setApprovalLevel($approvalLevel);
    $acceptance->setExpiryDate(new \DateTime('+1 year'));  // Annual review

    // Workflow sends notification to approver
    // After approval:
    $acceptanceWorkflowService->approveAcceptance($acceptance, 'Jane Doe - IT Manager');
    $risk->setStatus('Accepted');
}

Compliance Check:

✅ Treatment strategy selected and justified?

• RiskDashboardService - Real-time dashboards for ongoing monitoring

Clause 6.6: Risk Monitoring and Review

Requirement: Continuous monitoring, regular reviews

Implementation:

// Schedule periodic reviews
$risk->setNextReviewDate(new \DateTime('+6 months'));

// Find risks requiring review
$overdueReviews = $riskService->findRisksRequiringReview(new \DateTime());

// Monitor treatment plan progress
$overduePlans = $treatmentPlanService->getOverduePlans($tenant);

// Check expiring acceptances
$expiringAcceptances = $acceptanceWorkflowService->checkExpiringAcceptances(30);  // Next 30 days

ISO 31000 Framework Integration

Principles (Clause 4)

ISO 31000 defines 8 principles for effective risk management:

1. Integrated - Risk management embedded in all activities

   • Implementation: Multi-tenant risk context, cross-entity relationships (Asset, Control, Process)

2. Structured and Comprehensive - Systematic approach

   • Implementation: 5×5 risk matrix, formal workflows, standardized categories

3. Customized - Aligned to organization's context

   • Implementation: Configurable RiskAppetite per tenant, customizable impact criteria

4. Inclusive - Stakeholder engagement

   • Implementation: Risk owner assignment, approval workflows, communication tools

5. Dynamic - Responsive to change

   • Implementation: Continuous monitoring, incident-driven likelihood adjustment

6. Best Available Information - Based on data and analysis

   • Implementation: Data Reuse from Assets, Incidents, Controls (historical + real-time)

7. Human and Cultural Factors - Considers behavior

   • Implementation: Training requirements tracking, awareness campaigns, role-based access

8. Continual Improvement - Lessons learned

   • Implementation: Incident → Risk validation loop, treatment effectiveness tracking

Framework (Clause 5)

5.3: Design of Framework

ISO 31000 Requirement: Establish risk management framework

Application Implementation:

• Policy: Risk Management module in Admin settings
• Accountability: Risk owners, approval levels, tenant hierarchy
• Integration: Embedded in ISMS (ISO 27001), BCMS (ISO 22301)
• Resources: RiskService, RiskMatrixService, 8 specialized services
• Communication: RiskReportService, dashboards, notifications

5.4: Implementation

ISO 31000 Requirement: Implement risk management throughout organization

Workflow Example:

1. Context (5.4.2):
   - Define RiskAppetite for tenant
   - Configure risk matrix thresholds

2. Integration (5.4.3):
   - Link Risks to Assets (asset-centric approach)
   - Link Risks to BusinessProcesses (BCM integration)
   - Link Risks to Controls (ISO 27001 Annex A)

3. Accountability (5.4.4):
   - Assign risk owners
   - Define approval authority (Level 1-3)

4. Communication (5.4.5):
   - Generate executive summaries
   - Risk dashboards for management
   - Regular risk register reviews

5.5: Evaluation

ISO 31000 Requirement: Monitor framework effectiveness

KPIs in Application:

$dashboard = $riskReportService->generateRiskDashboard($tenant);
// Returns:
// - Total risks by level (Critical, High, Medium, Low)
// - Treatment plan completion rate
// - Residual risk trend (improving/worsening)
// - Risks exceeding appetite
// - Overdue treatments
// - Acceptance expiration rate

5.6: Improvement

ISO 31000 Requirement: Continually improve framework

Feedback Loops:

1. Incident → Risk: Incidents validate or adjust risk assessments
2. Control → Residual Risk: Control effectiveness drives improvement
3. Exercise → Treatment: BC exercises identify gaps in treatment plans
4. Audit → Process: Internal audits improve risk management process

---

ISO 27001 Integration

Annex A Controls

The application includes all 93 ISO 27001:2022 Annex A controls in the Control entity.

Risk-Control Mapping:

// Link risks to Annex A controls
$risk->addControl($controlA817);  // A.8.17 - Cloud services security

// Suggest relevant controls automatically
$suggestedControls = $treatmentPlanService->suggestControls($risk);
// For category 'Technical', threat 'Data Loss':
// Returns: A.8.13 (Backup), A.8.18 (Configuration management), A.8.24 (Cryptography)

Control Effectiveness Impact:

// Control effectiveness reduces residual risk
$control->setImplementationStatus('Implemented');
$control->setEffectiveness(85);  // 85% effective

// Residual likelihood = inherent × (1 - effectiveness)
// If inherent likelihood = 4, residual = 4 × (1 - 0.85) = 0.6 → 1 (Rare)

Clause 6.1.2: Information Security Risk Assessment

ISO 27001 Requirement: "The organization shall define and apply an information security risk assessment process"

Application Implementation:

• Risk assessment process defined through RiskService + RiskMatrixService
• 5×5 risk matrix meets "reproducible results" requirement
• Asset-centric approach aligns with ISO 27001 Clause 6.1.2(c)

Clause 6.1.3: Information Security Risk Treatment

ISO 27001 Requirement: Define risk treatment process, select controls

Application Implementation:

• RiskTreatmentPlanService implements formal treatment planning
• Control selection from Annex A (93 controls available)
• Residual risk acceptance workflow per 6.1.3(e)
• Statement of Applicability (SoA) links controls to risks

Clause 8.2: Information Security Risk Assessment

ISO 27001 Requirement: Perform risk assessments at planned intervals

Application Implementation:

// Scheduled reviews
$risk->setNextReviewDate(new \DateTime('+6 months'));

// Trigger-based reviews
if ($newIncident) {
    $riskProbabilityAdjustment->adjustLikelihood($risk);  // Re-evaluate
}

// Find overdue reviews
$overdueReviews = $riskService->findRisksRequiringReview(new \DateTime());

Common Risk Management Workflows

Workflow 1: New Risk Identification (ISO 27005 Clause 6.3.1)

User Request Patterns:

• "Help me identify risks for our new cloud migration project"
• "What risks should I consider for our customer database?"
• "Create a risk assessment for Asset X"

Agent Response:

1. Analyze Context - Read Asset/Business Process details
2. Suggest Threat Sources - Based on asset type and category
3. Identify Vulnerabilities - Check control coverage gaps
4. Draft Risk - Pre-fill fields using Data Reuse
5. Link Related Data - Connect to Assets, Controls, Incidents

Example:

User: "Help me assess risks for our customer database (Asset #42)"

Agent Actions:
1. Read Asset #42 details:
   - Type: Database Server
   - Contains: 50,000 customer records (personal data)
   - CIA: C=5, I=5, A=4
   - Monetary Value: €200,000
   - Location: AWS eu-central-1

2. Suggest risks based on asset profile:
   a) Unauthorized access (External threat)
   b) Data breach (GDPR Art. 32 violation)
   c) Ransomware attack (Malware threat)
   d) Accidental deletion (Human error)
   e) Cloud provider outage (Third-party dependency)

3. For Risk (a) - Draft pre-filled risk:
   - Name: "Unauthorized Access to Customer Database"
   - Category: Technical
   - Threat Source: External
   - Vulnerability: "Check current controls for A.5.15 (Access control)"
   - Assets: [Asset #42] (linked)
   - Financial Impact: €200,000 + GDPR fine (€10M or 2% revenue)
   - Compliance Impact: GDPR Art. 32 (Security), Art. 33 (Breach notification)
   - Impact: 5 (Critical) - based on personal data + high value
   - Likelihood: 3 (Possible) - check incident history for similar attacks

4. Present to user for review and confirmation

Workflow 2: Risk Assessment Update (ISO 27005 Clause 6.6)

User Request Patterns:

• "Update risk likelihood based on recent incidents"
• "Recalculate residual risk after implementing MFA"
• "Review risk #15"

Agent Response:

1. Check Incident History - Has new incident data emerged?
2. Check Control Status - Have controls been implemented/updated?
3. Recalculate Scores - Apply Data Reuse services
4. Compare to Appetite - Does risk still meet acceptance criteria?
5. Recommend Actions - Treatment plan updates if needed

Example:

User: "Risk #15 (Phishing Attack) needs review after 3 incidents this month"

Agent Actions:
1. Read Risk #15 current state:
   - Inherent: Impact 4, Likelihood 3, Score 12 (High)
   - Residual: Impact 4, Likelihood 2, Score 8 (Medium) - with security awareness training
   - Status: Accepted (1 year ago)

2. Analyze new incident data:
   - 3 phishing incidents in past 30 days (escalation!)
   - 2 of 3 bypassed email filtering
   - 1 resulted in credential compromise

3. Adjust likelihood using RiskProbabilityAdjustmentService:
   - Historical frequency: 3 incidents / month = 36 annualized
   - Previous likelihood (2 - Unlikely) no longer valid
   - New likelihood: 5 (Almost Certain)
   - New inherent risk: 4 × 5 = 20 (Critical!)

4. Recalculate residual risk:
   - Current control (awareness training) effectiveness: 40% (low, incidents show)
   - Residual likelihood: 5 × (1 - 0.40) = 3 (Possible)
   - Residual risk: 4 × 3 = 12 (High)

5. Check against risk appetite:
   - Appetite for Technical risks: 9 (Medium)
   - Current residual risk 12 EXCEEDS appetite → Treatment required!

6. Recommend actions:
   - Invalidate current risk acceptance (risk profile changed)
   - Create new treatment plan:
     * Implement MFA (A.5.17)
     * Deploy advanced email filtering (A.12.2.1)
     * Increase training frequency
   - Set priority to 5 (Critical)
   - Escalate to senior management (residual risk 12)

7. Draft updated risk for user approval

Workflow 3: Risk Treatment Planning (ISO 27005 Clause 6.4)

User Request Patterns:

• "Create treatment plan for Risk #23"
• "Suggest controls to reduce this risk"
• "How can I mitigate risk of data loss?"

Agent Response:

1. Analyze Risk Profile - Current inherent/residual scores
2. Suggest Treatment Strategy - Based on risk level and appetite
3. Recommend ISO 27001 Controls - From Annex A, using Data Reuse
4. Estimate Residual Risk - Calculate expected outcome
5. Create Treatment Plan - With timeline, owner, budget

Example:

User: "Create treatment plan for Risk #8 (SQL Injection vulnerability)"

Agent Actions:
1. Read Risk #8:
   - Inherent: Impact 5, Likelihood 4, Score 20 (Critical)
   - Category: Technical
   - Affected Assets: Web Application (Asset #55), Database (Asset #56)
   - Current controls: None
   - Risk appetite for Technical: 9 (Medium)

2. Determine strategy:
   - Residual risk 20 far exceeds appetite 9 → "Reduce" required
   - Risk level Critical → Urgent treatment needed

3. Suggest relevant ISO 27001 controls:
   - A.8.8: Management of technical vulnerabilities (Primary)
   - A.8.25: Secure development lifecycle (Secondary)
   - A.14.2.1: Secure development policy (Supporting)
   - A.8.19: Security testing (Verification)

4. Estimate effectiveness:
   - Input validation + parameterized queries: 95% effective
   - WAF (Web Application Firewall): 80% effective
   - Combined: ~98% effective

5. Calculate expected residual risk:
   - Residual likelihood: 4 × (1 - 0.98) = 0.08 → 1 (Rare)
   - Residual risk: 5 × 1 = 5 (Medium) ✓ Below appetite (9)

6. Create treatment plan:
   Strategy: Reduce
   Actions:
   - Immediate: Deploy WAF (ETA: 2 weeks, Cost: €5,000)
   - Short-term: Code review + fix vulnerabilities (ETA: 4 weeks, Cost: €15,000)
   - Long-term: Implement secure SDLC (ETA: 3 months, Cost: €30,000)
   Responsible: Lead Developer + IT Security Manager
   Target: 30 days for critical fixes
   Verification: Penetration test after implementation
   Total Cost: €50,000

7. Present plan to user for approval

Workflow 4: Risk Acceptance Process (ISO 27005 Clause 6.4.4)

User Request Patterns:

• "Accept Risk #12"
• "This risk is too expensive to mitigate, can we accept it?"
• "Create formal risk acceptance for residual risk"

Agent Response:

1. Validate Acceptance Criteria - Is residual risk within appetite?
2. Determine Approval Level - Based on risk score
3. Draft Justification - Using cost-benefit analysis
4. Create Acceptance Request - Formal documentation
5. Initiate Workflow - Route to appropriate approver

Example:

User: "Accept Risk #19 (Legacy system vulnerability)"

Agent Actions:
1. Read Risk #19:
   - Residual risk: 6 (Medium)
   - Risk appetite for Operational: 9 (Medium)
   - Residual risk 6 < appetite 9 ✓ Acceptable within tolerance

2. Check if treatment is cost-effective:
   - Estimated annual loss: €10,000 (impact 3 × likelihood 2)
   - Treatment cost (system upgrade): €80,000
   - ROI: Negative (treatment costs 8x more than potential loss)
   - Conclusion: Acceptance justified on cost-benefit basis

3. Determine approval level:
   - Residual risk 6 (Medium) → Approval Level 1 (Manager)
   - No need for senior management/board approval

4. Draft acceptance justification:
   "Risk #19 (Legacy System Vulnerability) acceptance is recommended:

   Rationale:
   - Residual risk (6) is below risk appetite threshold (9)
   - Treatment cost (€80k system upgrade) exceeds 10-year potential loss (€100k)
   - Legacy system scheduled for decommission in 18 months
   - Compensating controls in place: Network segmentation, enhanced monitoring

   Conditions:
   - Monthly vulnerability scans
   - Quarterly penetration testing
   - Immediate escalation if exploit detected in wild
   - Re-evaluate if decommission timeline extends beyond 2 years

   Review: Annual (earlier if threat landscape changes)"

5. Create RiskAcceptance entity:
   - Justification: [above text]
   - Approval Level: 1
   - Expiry Date: +1 year
   - Conditions: [monitoring requirements]
   - Status: Pending

6. Route to IT Manager for approval (automatic workflow notification)

7. Inform user: "Risk acceptance request created and sent to IT Manager for approval"

Workflow 5: Asset Risk Assessment (ISO 27005 Asset-Centric)

User Request Patterns:

• "What's the risk score for Asset #42?"
• "Show me all high-risk assets"
• "Assess security posture of our file servers"

Agent Response:

1. Calculate Comprehensive Risk Score - Using AssetRiskCalculatorService (Data Reuse)
2. Analyze Contributing Factors - CIA, active risks, incidents, controls, value
3. Identify Gaps - Missing controls, overdue treatments
4. Recommend Actions - Prioritized improvement list

Example:

User: "Assess risk for our Customer Portal (Asset #77)"

Agent Actions:
1. Read Asset #77:
   - Type: Web Application
   - Contains: Customer data (GDPR personal data)
   - CIA: C=5, I=5, A=4
   - Monetary Value: €150,000
   - Location: Public internet

2. Calculate comprehensive risk score:
   $riskData = $assetRiskCalculatorService->calculateAssetRisk($asset77);

   Results:
   - Base CIA score: 47/100
   - Active risks:
     * Risk #8: SQL Injection (20 - Critical)
     * Risk #11: DDoS Attack (12 - High)
     * Risk #23: Session Hijacking (9 - Medium)
     Total risk exposure: +35 points
   - Incident history:
     * 2 incidents in past year (downtime events)
     +8 points
   - Control coverage:
     * 14/20 applicable ISO 27001 controls implemented (70%)
     * Missing: A.8.8, A.8.19, A.13.1.3, A.14.2.1, A.14.2.8, A.18.2.3
     -10 points (reduction for gaps)
   - Business criticality:
     * Linked to Business Process "Customer Service" (Criticality 4)
     +5 points

   Final Score: 85/100 (High Risk) 🔴

3. Analyze findings:
   - Primary concern: Critical SQL Injection vulnerability (Risk #8)
   - Secondary: Missing development security controls
   - Positive: Good baseline control coverage (70%)

4. Recommend prioritized actions:
   Priority 1 (Urgent - 30 days):
   - Address Risk #8 (SQL Injection) - implement treatment plan
   - Implement A.8.8 (Technical vulnerability management)
   - Implement A.8.19 (Security testing in SDLC)

   Priority 2 (Important - 90 days):
   - Implement A.14.2.1 (Secure development policy)
   - Implement A.14.2.8 (System security testing)
   - Review session management (Risk #23)

   Priority 3 (Standard - 6 months):
   - Implement A.13.1.3 (Network segregation)
   - Implement A.18.2.3 (Technical compliance review)
   - Address DDoS risk (Risk #11) - consider CDN/WAF

   Expected outcome:
   - After Priority 1 actions: Score reduces to ~60/100 (Medium)
   - After Priority 2 actions: Score reduces to ~40/100 (Low)
   - After Priority 3 actions: Score reduces to ~25/100 (Low)

5. Present report to user with actionable roadmap

Troubleshooting & Common Issues

Issue 1: Residual Risk Not Calculating

Symptoms: Residual risk equals inherent risk despite controls linked

Root Causes:

1. Controls not marked as "Implemented"

   $control->setImplementationStatus('Planned');  // ❌ Doesn't reduce risk
   $control->setImplementationStatus('Implemented');  // ✅ Reduces risk
   

2. Control effectiveness not set

   $control->setEffectiveness(null);  // ❌ Treated as 0%
   $control->setEffectiveness(80);     // ✅ 80% effective
   

3. No controls linked to risk

   $risk->getControls()->isEmpty();  // ❌ Check this
   $risk->addControl($control);      // ✅ Link controls
   

Solution:

// Verify control status
foreach ($risk->getControls() as $control) {
    if ($control->getImplementationStatus() !== 'Implemented') {
        // Log warning or update status
    }
    if ($control->getEffectiveness() === null) {
        // Set default effectiveness based on control type
    }
}

// Recalculate
$residualRisk = $riskService->calculateResidualRisk($risk);

Issue 2: Risk Acceptance Workflow Stuck

Symptoms: Acceptance status remains "Pending" indefinitely

Root Causes:

1. Wrong approval level assigned

   $acceptance->setApprovalLevel(3);  // Requires Board approval (slow)
   // Should be Level 1 for low residual risks
   

2. Approver not notified (workflow configuration issue)

3. Expiry date in past

   $acceptance->getExpiryDate() < new \DateTime();  // ❌ Expired
   

Solution:

// Check approval level matches residual risk
$correctLevel = $acceptanceWorkflowService->determineApprovalLevel($risk);
if ($acceptance->getApprovalLevel() !== $correctLevel) {
    $acceptance->setApprovalLevel($correctLevel);
}

// Check expiry
if ($acceptance->getExpiryDate() < new \DateTime()) {
    $acceptance->setExpiryDate(new \DateTime('+1 year'));
}

// Find pending acceptances for follow-up
$pendingAcceptances = $acceptanceRepository->findBy([
    'status' => 'Pending',
    'tenant' => $tenant
]);

Issue 3: Risk Impact Suggestions Inaccurate

Symptoms: RiskImpactCalculatorService suggests wrong impact level

Root Causes:

1. Asset monetary value not set or outdated

   $asset->getMonetaryValue() === null;  // ❌ Can't calculate
   

2. Asset CIA ratings incorrect

   $asset->getConfidentiality() === 1;  // ❌ Set to Negligible but contains critical data
   

3. Compliance impact not considered

   $asset->containsPersonalData() === true;  // GDPR implications not reflected
   

Solution:

// Validate asset data before risk assessment
if ($asset->getMonetaryValue() === null) {
    // Prompt user to set monetary value
    // Or estimate from asset type + quantity
}

// Verify CIA ratings
if ($asset->containsPersonalData() && $asset->getConfidentiality() < 4) {
    // Warning: Personal data should have high confidentiality
}

// Override automatic suggestion if needed
$suggestedImpact = $riskImpactCalculatorService->suggestImpactLevel($asset, 'Confidentiality');
// User can adjust based on context
$risk->setInherentImpact($suggestedImpact + 1);  // Increase due to GDPR

Issue 4: Incident History Not Affecting Likelihood

Symptoms: RiskProbabilityAdjustmentService not increasing likelihood despite incidents

Root Causes:

1. Incidents not linked to risk

   $risk->getIncidents()->isEmpty();  // ❌ No data to analyze
   

2. Incidents too old (outside analysis window)

   $incident->getIncidentDate() < new \DateTime('-2 years');  // Outside 12-month window
   

3. Incident severity not set

   $incident->getSeverity() === null;  // Can't weight impact
   

Solution:

// Link related incidents
$relatedIncidents = $incidentRepository->findBySimilarThreat($risk->getThreatSource());
foreach ($relatedIncidents as $incident) {
    if ($incident->getIncidentDate() > new \DateTime('-1 year')) {
        $risk->addIncident($incident);
    }
}

// Verify incident data quality
foreach ($risk->getIncidents() as $incident) {
    if ($incident->getSeverity() === null) {
        // Estimate severity from financial impact
    }
}

// Recalculate likelihood
$adjustedLikelihood = $riskProbabilityAdjustmentService->adjustLikelihood($risk);

Issue 5: Data Reuse Not Working

Symptoms: Services not leveraging existing Asset/Incident/Control data

Root Causes:

1. Relationships not persisted

   $risk->addAsset($asset);  // ❌ Not saved
   $entityManager->flush();   // ✅ Persist relationships
   

2. Services called before relationships established

   $impact = $riskImpactCalculator->calculateFinancialImpact($risk);  // ❌ No assets linked yet
   $risk->addAsset($asset);  // Too late
   

3. Tenant context mismatch

   $risk->getTenant() !== $asset->getTenant();  // ❌ Cross-tenant reference
   

Solution:

// Correct order of operations:
// 1. Create risk
$risk = new Risk();
$risk->setTenant($tenant);

// 2. Link related entities (Data Reuse setup)
$risk->addAsset($asset);
$risk->addIncident($incident);
$risk->addControl($control);
$risk->setBusinessProcess($businessProcess);

// 3. Persist relationships
$entityManager->persist($risk);
$entityManager->flush();

// 4. NOW use Data Reuse services
$suggestedImpact = $riskImpactCalculatorService->suggestImpactLevel($asset, 'Financial');
$adjustedLikelihood = $riskProbabilityAdjustmentService->adjustLikelihood($risk);
$appetiteCheck = $riskAppetitePrioritizationService->checkAgainstAppetite($risk);

---

Best Practices

1. Always Use Data Reuse Services

DON'T:

// Manual calculation (error-prone, time-consuming)
$risk->setInherentImpact(4);  // Guess based on intuition
$risk->setInherentLikelihood(3);  // No data backing

DO:

// Use services to leverage existing data
$risk->addAsset($asset);  // Link asset first
$suggestedImpact = $riskImpactCalculatorService->suggestImpactLevel($asset, 'Financial');
$risk->setInherentImpact($suggestedImpact);  // Data-backed suggestion

$suggestedLikelihood = $riskProbabilityAdjustmentService->suggestLikelihood($risk->getThreatSource(), $tenant);
$risk->setInherentLikelihood($suggestedLikelihood);  // Based on incident history

2. Link Risks to Business Processes (ISO 22301 Integration)

WHY: Ensures business continuity planning considers risks

DO:

// Link risk to critical business process
$payrollProcess = $businessProcessRepository->find(15);
$risk->setBusinessProcess($payrollProcess);

// System automatically:
// - Inherits criticality level (5 - Critical)
// - Sets treatment deadline based on RTO (4 hours)
// - Links to BC Plan for this process
// - Escalates priority

3. Review Risks After Incidents (ISO 27005 Clause 6.6)

WHY: Incidents validate or invalidate risk assessments

DO:

// After incident occurs, review related risks
$incident = new Incident();
$incident->setIncidentType('Ransomware');
$incident->setSeverity('High');

// Find related risks
$relatedRisks = $riskRepository->findByThreatSource('Malware');

foreach ($relatedRisks as $risk) {
    // Link incident
    $risk->addIncident($incident);

    // Recalculate likelihood
    $newLikelihood = $riskProbabilityAdjustmentService->adjustLikelihood($risk);
    if ($newLikelihood > $risk->getInherentLikelihood()) {
        // Likelihood increased - invalidate acceptance, require new treatment
        $risk->setStatus('In_Treatment');
        // Notify risk owner
    }
}

4. Set Risk Appetite Before Risk Assessment (ISO 31000)

WHY: Provides consistent evaluation criteria across organization

DO:

// 1. Define risk appetite (one-time setup per tenant)
$appetite = new RiskAppetite();
$appetite->setCategory('Financial');
$appetite->setMaxAcceptableRisk(12);  // High threshold
$appetite->setApprovedBy('CFO');
$appetite->setStatus('Active');

// 2. Now assess risks with clear acceptance criteria
$risk->setResidualRisk(15);
$check = $riskAppetitePrioritizationService->checkAgainstAppetite($risk);
if ($check['exceeds']) {
    // Clear decision: Residual risk 15 > appetite 12 → Treatment required
}

5. Document Risk Acceptance Conditions (ISO 27005)

WHY: Ensures acceptance is conditional and reviewable

DO:

$acceptance = new RiskAcceptance();
$acceptance->setJustification('Treatment cost (€50k) exceeds annual expected loss (€15k)');
$acceptance->setConditions('
    - Monthly vulnerability scans must show no critical findings
    - Quarterly penetration tests required
    - If exploited in wild, immediate escalation and treatment
    - Re-evaluate if asset value increases beyond €200k
');
$acceptance->setExpiryDate(new \DateTime('+1 year'));  // Annual review

6. Use ISO 27001 Controls for Treatment (Integration)

WHY: Ensures treatment aligns with ISMS, avoids duplication

DO:

// Suggest controls from Annex A
$suggestedControls = $treatmentPlanService->suggestControls($risk);

// Link to treatment plan
$plan = new RiskTreatmentPlan();
foreach ($suggestedControls as $control) {
    $plan->addControl($control);
    // Control implementation tracked in ISMS module
    // No duplicate tracking needed
}

7. Calculate Residual Risk After Each Control Update

WHY: Monitors treatment effectiveness

DO:

// After implementing control
$control->setImplementationStatus('Implemented');
$control->setImplementationDate(new \DateTime());
$control->setEffectiveness(85);

// Recalculate residual risk
$residualRisk = $riskService->calculateResidualRisk($risk);
$risk->setResidualRisk($residualRisk);

// Check if now within appetite
$check = $riskAppetitePrioritizationService->checkAgainstAppetite($risk);
if (!$check['exceeds']) {
    // Treatment successful - can now accept residual risk
    $risk->setStatus('Mitigated');
}

When to Escalate to ISO Standards

For detailed guidance, refer to:

• iso-27005-reference.md - Full ISO 27005:2022 standard reference
• iso-31000-reference.md - Full ISO 31000:2018 framework reference

Use ISO 27005 when:

• User asks about specific clauses (e.g., "ISO 27005 Clause 6.3.2")
• Detailed methodology questions (e.g., "How to perform qualitative risk analysis per ISO 27005?")
• Audit preparation (e.g., "What evidence does ISO 27005 require for risk assessment?")

Use ISO 31000 when:

• User asks about risk management framework principles
• Organization-wide risk management strategy questions
• Integration with enterprise risk management (ERM)
