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:
- Isolate affected systems
- Preserve evidence
- Block threat vectors
- Remove malicious artifacts
Validation: Containment confirmed, no ongoing compromise.
Step 4: Recovery and Lessons Learned
Post-incident activities:
- Restore systems from clean backups
- Verify integrity before reconnection
- Document timeline and actions
- Conduct post-incident review
- Update controls and procedures
Validation: Post-incident report completed within 5 business days.

Validation Checkpoints
ISMS Implementation Validation

|---|
| Scope | Scope approved | Signed scope document |
| Risk | Register complete | Risk register with owners |
| Controls | SoA approved | Statement of Applicability |

| Audit | Internal audit done | Audit report |
Certification Readiness
Before Stage 1 audit:
- ISMS scope documented and approved
- Information security policy published
- Risk assessment completed
- Statement of Applicability finalized
- Internal audit conducted
- Management review completed
- Nonconformities addressed
Before Stage 2 audit:
- Controls implemented and operational
- Evidence of effectiveness available
- Staff trained and aware
- Incidents logged and managed
- Metrics collected for 3+ months
Compliance Verification
Run periodic checks:
# Monthly compliance check
python scripts/compliance_checker.py --standard iso27001 --output monthly_$(date +%Y%m).md
# Quarterly gap analysis
python scripts/compliance_checker.py --standard iso27001 --gap-analysis --output quarterly_gaps.md

| A002 | EHR application | Software | App Team | Critical |
| A003 | Database server | Hardware | Infra Team | High |
| A004 | Admin credentials | Access | Security | Critical |
Step 2: Identify Risks
Risk register output:
| Risk ID | Asset | Threat | Vulnerability | L | I | Score |
|---|
| R001 | A001 | Data breach | Weak encryption | 3 | 5 | 15 |
| R002 | A002 | SQL injection | Input validation | 4 | 4 | 16 |
| R003 | A004 | Credential theft | No MFA | 4 | 5 | 20 |
Step 3: Determine Treatment
| Risk | Treatment | Control | Timeline |
|---|
| R001 | Mitigate | Implement AES-256 encryption | 30 days |
| R002 | Mitigate | Add input validation, WAF | 14 days |
| R003 | Mitigate | Enforce MFA for all admins | 7 days |
Step 4: Verify Implementation
