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.

Validation Checkpoints

ISMS Implementation Validation

Phase	Checkpoint	Evidence Required
Scope	Scope approved	Signed scope document
Risk	Register complete	Risk register with owners
Controls	SoA approved	Statement of Applicability
Operation	Metrics active	Dashboard screenshots
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

Worked Example: Healthcare Risk Assessment

Scenario: Assess security risks for a patient data management system.

Step 1: Define Assets

python scripts/risk_assessment.py --scope "patient-data-system" --template healthcare

Asset inventory output:

Asset ID	Asset	Type	Owner	Classification
A001	Patient database	Information	DBA Team	Confidential
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

python scripts/compliance_checker.py --controls-file implemented_controls.csv

Verification output:
