Workflows

Workflow 1: ISMS Implementation

Step 1: Define Scope and Context

Document organizational context and ISMS boundaries:

• Identify interested parties and requirements
• Define ISMS scope and boundaries
• Document internal/external issues

Validation: Scope statement reviewed and approved by management.

Step 2: Conduct Risk Assessment

python scripts/risk_assessment.py --scope "full-organization" --template general --output initial_risks.json

• Identify information assets
• Assess threats and vulnerabilities
• Calculate risk levels
• Determine risk treatment options

Validation: Risk register contains all critical assets with assigned owners.

Step 3: Select and Implement Controls

Map risks to ISO 27002 controls:

python scripts/compliance_checker.py --standard iso27002 --gap-analysis --output control_gaps.md

Control categories:

• Organizational (policies, roles, responsibilities)
• People (screening, awareness, training)
• Physical (perimeters, equipment, media)
• Technological (access, crypto, network, application)

Validation: Statement of Applicability (SoA) documents all controls with justification.

Step 4: Establish Monitoring

Define security metrics:

• Incident count and severity trends
• Control effectiveness scores
• Training completion rates
• Audit findings closure rate

Validation: Dashboard shows real-time compliance status.

Workflow 2: Security Risk Assessment

Step 1: Asset Identification

Create asset inventory:

| Asset Type | Examples | Classification |

|------------|----------|----------------|

| Information | Patient records, source code | Confidential |

| Software | EHR system, APIs | Critical |

| Hardware | Servers, medical devices | High |

| Services | Cloud hosting, backup | High |

| People | Admin accounts, developers | Varies |

Validation: All assets have assigned owners and classifications.

Step 2: Threat Analysis

Identify threats per asset category:

| Asset | Threats | Likelihood |

|-------|---------|------------|

| Patient data | Unauthorized access, breach | High |

| Medical devices | Malware, tampering | Medium |

| Cloud services | Misconfiguration, outage | Medium |

| Credentials | Phishing, brute force | High |

Validation: Threat model covers top-10 industry threats.

Step 3: Vulnerability Assessment

python scripts/risk_assessment.py --scope "network-infrastructure" --output vuln_risks.json

Document vulnerabilities:

• Technical (unpatched systems, weak configs)
• Process (missing procedures, gaps)
• People (lack of training, insider risk)

Validation: Vulnerability scan results mapped to risk register.

Step 4: Risk Evaluation and Treatment

Calculate risk: Risk = Likelihood × Impact

| Risk Level | Score | Treatment |

|------------|-------|-----------|

| Critical | 20-25 | Immediate action required |

| High | 15-19 | Treatment plan within 30 days |

| Medium | 10-14 | Treatment plan within 90 days |

| Low | 5-9 | Accept or monitor |

| Minimal | 1-4 | Accept |

Validation: All high/critical risks have approved treatment plans.

Workflow 3: Incident Response

Step 1: Detection and Reporting

Incident categories:

• Security breach (unauthorized access)
• Malware infection
• Data leakage
• System compromise
• Policy violation

Validation: Incident logged within 15 minutes of detection.

Step 2: Triage and Classification

| Severity | Criteria | Response Time |

|----------|----------|---------------|

| Critical | Data breach, system down | Immediate |

| High | Active threat, significant risk | 1 hour |

| Medium | Contained threat, limited impact | 4 hours |

| Low | Minor violation, no impact | 24 hours |

Validation: Severity assigned and escalation triggered if needed.

Step 3: Containment and Eradication

Immediate actions:

1. Isolate affected systems
2. Preserve evidence
3. Block threat vectors
4. Remove malicious artifacts

Validation: Containment confirmed, no ongoing compromise.

Step 4: Recovery and Lessons Learned

Post-incident activities:

1. Restore systems from clean backups
2. Verify integrity before reconnection
3. Document timeline and actions
4. Conduct post-incident review
5. Update controls and procedures

Validation: Post-incident report completed within 5 business days.
