Description

This curriculum spans the equivalent of a multi-workshop technical advisory engagement, covering the design, implementation, and operational enforcement of data integrity controls across ISMS processes, identity governance, system configurations, third-party interactions, and incident response workflows.

Module 1: Defining Data Integrity Objectives within ISMS Frameworks

Selecting data classification criteria based on regulatory impact, business criticality, and data lifecycle stage
Mapping data integrity requirements from ISO 27001 Annex A controls (e.g., A.8.10, A.12.4) to specific business processes
Establishing ownership models for data sets across departments to ensure accountability
Integrating data integrity into risk assessment methodologies used during ISMS implementation
Aligning data integrity policies with existing information security policies without creating redundancy
Documenting integrity baselines for structured vs. unstructured data in policy artifacts
Defining acceptable thresholds for data drift or inconsistency in operational systems
Conducting gap analysis between current data handling practices and ISO 27001 control expectations

Module 2: Data Classification and Handling Procedures

Implementing automated tagging for sensitive data using DLP tools integrated with classification schemas
Configuring access control policies based on data classification levels in IAM systems
Designing handling rules for data in transit, at rest, and in use according to classification
Enforcing encryption standards for high-integrity data categories across storage platforms
Developing procedures for secure printing, downloading, and sharing of classified data
Creating data labeling workflows that support both human readability and machine parsing
Updating classification rules in response to changes in regulatory scope (e.g., GDPR, HIPAA)
Validating classification accuracy through periodic data sampling and audit

Module 3: Access Control and Identity Governance

Implementing role-based access control (RBAC) aligned with data integrity sensitivity tiers
Enforcing least privilege access through regular access review cycles and attestation
Integrating identity lifecycle management with HR systems to automate provisioning/deprovisioning
Configuring privileged access management (PAM) for administrative operations on critical data stores
Applying time-bound access grants for contractors working with high-integrity systems
Logging and monitoring access to data integrity-critical systems using SIEM integration
Defining segregation of duties (SoD) rules to prevent unauthorized data modification
Responding to access anomalies detected through behavioral analytics in identity systems

Module 4: Secure Configuration and System Hardening

Applying CIS benchmarks to harden database servers hosting integrity-sensitive data
Disabling unnecessary services and ports on systems that process or store critical data
Implementing configuration baselines for cloud databases (e.g., AWS RDS, Azure SQL) to prevent misconfigurations
Using infrastructure-as-code (IaC) templates to enforce consistent, auditable system configurations
Validating configuration compliance through automated scanning tools (e.g., Ansible, Chef InSpec)
Managing cryptographic key storage and access in alignment with system security policies
Configuring database audit logging to capture all DDL and DML operations on core tables
Enforcing secure boot and firmware integrity checks on physical servers handling regulated data

Module 5: Change Management and Configuration Control

Requiring formal change requests for any modification to systems storing or processing high-integrity data
Implementing peer review and approval workflows for database schema changes
Using version-controlled repositories for all configuration and database migration scripts
Conducting impact assessments on data integrity before approving infrastructure changes
Enforcing maintenance windows for changes to minimize disruption to data processes
Rolling back unauthorized or failed changes using automated recovery procedures
Integrating change management systems (e.g., ServiceNow) with monitoring tools to detect out-of-band changes
Documenting all changes with rationale, testing results, and backout plans in audit logs

Module 6: Logging, Monitoring, and Anomaly Detection

Centralizing logs from databases, applications, and access systems into a secured SIEM platform
Defining log retention periods based on regulatory requirements and forensic needs
Creating correlation rules to detect suspicious data modification patterns (e.g., bulk deletions)
Ensuring log integrity through write-once storage and cryptographic hashing mechanisms
Monitoring for unauthorized exports or transfers of sensitive data using DLP alerts
Validating that logging is enabled and functioning across all critical data systems
Responding to alerts indicating tampering with audit trails or log disabling attempts
Conducting periodic log reviews as part of internal audit and compliance testing

Module 7: Backup, Recovery, and Data Resilience

Defining recovery point objectives (RPO) and recovery time objectives (RTO) for critical data sets
Encrypting backup data both in transit and at rest using FIPS-validated modules
Validating backup integrity through periodic restore testing in isolated environments
Storing backups in geographically separate locations to mitigate site-level risks
Implementing immutable or write-once storage for backups to prevent tampering
Documenting and testing data recovery procedures as part of business continuity planning
Ensuring backup systems are included in access control and monitoring frameworks
Reviewing backup logs for signs of unauthorized access or deletion attempts

Module 8: Third-Party and Supply Chain Data Governance

Requiring third-party vendors to demonstrate compliance with data integrity controls via audits or certifications
Including data integrity clauses in contracts and SLAs with cloud service providers
Conducting technical assessments of vendor systems that process or store organizational data
Implementing API-level controls to validate data integrity during exchanges with partners
Monitoring data flows to and from third parties using network traffic analysis tools
Requiring encryption and access logging for all data shared externally
Establishing breach notification timelines and data remediation responsibilities in vendor agreements
