Description

This curriculum spans the design, operation, and governance of backup systems with the structural rigor of an internal ISO 27001 compliance program, matching the depth of work typically managed across multiple risk and infrastructure teams in regulated organizations.

Module 1: Alignment of Backup Strategy with ISO 27001 Information Security Objectives

Determine which information assets require backup based on classification levels defined in ISO 27001 Annex A.8.2.1.
Define recovery objectives (RTO and RPO) for critical systems in coordination with business impact analysis outcomes.
Select backup methods (full, incremental, differential) based on system criticality and storage constraints.
Map backup requirements to specific ISO 27001 controls, including A.12.3.1 and A.14.2.7.
Integrate backup planning into the Statement of Applicability (SoA) with documented justifications for inclusions or exclusions.
Establish retention periods aligned with legal, regulatory, and operational requirements.
Coordinate with data owners to validate backup scope and frequency for databases, file servers, and cloud workloads.
Document exceptions where real-time replication replaces traditional backups, with risk acceptance from senior management.

Module 2: Risk Assessment and Backup Control Implementation

Conduct threat modeling for backup systems, including risks of ransomware encryption and insider deletion.
Perform vulnerability assessments on backup servers and storage media to identify exposure to unpatched systems.
Implement access controls to backup repositories based on the principle of least privilege.
Evaluate risks associated with third-party backup providers and ensure contractual obligations align with ISO 27001.
Assess the impact of backup failure on business continuity and update risk treatment plans accordingly.
Classify backup data with the same sensitivity level as the source information to enforce protection controls.
Document risk treatment decisions for unprotected legacy systems that cannot support automated backups.
Integrate backup-related incidents into the organization’s risk register for ongoing monitoring.

Module 3: Design and Architecture of Secure Backup Infrastructure

Architect a 3-2-1 backup topology: three copies, two media types, one offsite, with documented exceptions.
Isolate backup networks from production environments using VLANs or air-gapped systems where feasible.
Select encryption standards (e.g., AES-256) for data at rest and in transit based on organizational policy.
Deploy immutable storage or write-once-read-many (WORM) solutions to prevent tampering with backups.
Size backup storage pools based on growth projections and retention policies to avoid capacity overruns.
Integrate backup systems with centralized logging and monitoring tools for audit trail consistency.
Design failover mechanisms for backup servers to maintain protection during infrastructure outages.
Specify hardware compatibility matrices when integrating tape libraries or cloud gateways.

Module 4: Backup Policy Development and Compliance Enforcement

Draft a formal backup policy approved by senior management, referencing ISO 27001 control A.12.3.1.
Define roles and responsibilities for backup operators, custodians, and auditors in policy documentation.
Enforce mandatory backup scheduling for all systems listed in the asset inventory.
Establish procedures for handling backup media transport, including chain-of-custody logs.
Mandate encryption of portable backup media per organizational cryptographic policy.
Define consequences for non-compliance with backup procedures in disciplinary policies.
Require periodic review and update of the backup policy at least annually or after major incidents.
Align policy enforcement with internal audit requirements and external certification timelines.

Module 5: Operational Execution and Monitoring of Backup Processes

Schedule automated backups during maintenance windows to minimize performance impact on production systems.
Monitor backup job success rates and investigate recurring failures within four hours of alert.
Generate daily reports listing completed, failed, and skipped backup jobs for operations review.
Implement automated verification of backup integrity using checksums or test restores.
Rotate backup operators to prevent single points of knowledge and detect procedural deviations.
Log all administrative actions on backup software, including configuration changes and media ejection.
Respond to media failure alerts by initiating replacement procedures and updating inventory records.
Track backup storage utilization weekly and trigger capacity planning when thresholds exceed 80%.

Module 6: Testing, Restoration, and Recovery Validation

Conduct quarterly restoration tests for critical systems, documenting success and elapsed time.
Simulate full system recovery in isolated environments to validate recovery procedures.
Test restoration of individual files, databases, and virtual machines based on business priority.
Measure actual RTO and RPO against defined targets and adjust backup frequency if exceeded.
Involve application owners in validation to confirm data consistency post-restore.
Document restoration test outcomes and distribute findings to risk and operations teams.
Update recovery runbooks based on lessons learned from test exercises.
Retain test logs as evidence for ISO 27001 internal and external audits.

Module 7: Third-Party and Cloud Backup Management

Verify that cloud backup providers comply with ISO 27001 or equivalent frameworks through audit reports.
Negotiate SLAs that specify backup frequency, retention, and restoration timelines.
Ensure customer-managed encryption keys are used when storing backups with public cloud providers.
Validate that backup data stored in foreign jurisdictions complies with data residency regulations.
Conduct due diligence on SaaS applications that perform their own backups, assessing adequacy.
Integrate third-party backup logs into the organization’s SIEM for centralized monitoring.
Define exit strategies for backup data retrieval upon contract termination with vendors.
Require contractual indemnification for data loss caused by provider operational failures.

Module 8: Incident Response and Backup Integrity Assurance

Include backup systems in incident response playbooks for ransomware and data corruption events.
Isolate backup repositories immediately upon detection of a compromise in the production environment.
Verify the cleanliness of backup images before initiating restoration after a security incident.
Preserve forensic copies of corrupted or infected backups for post-incident analysis.
Activate emergency backup procedures for systems not covered under standard schedules during crises.
Coordinate with legal and compliance teams when backup data is required as evidence.
Document all actions taken during backup-related incidents for regulatory reporting.
Conduct post-incident reviews to update backup controls based on root cause findings.

Module 9: Audit Preparation and Continuous Improvement

Compile evidence packs for auditors, including backup logs, test results, and policy documents.
Respond to audit findings related to backup gaps with formal corrective action plans.
Update backup procedures based on changes in technology, regulations, or business processes.
Conduct internal control assessments semi-annually to verify adherence to backup policy.
Map backup control effectiveness to key risk indicators (KRIs) for executive reporting.
Integrate backup metrics into the organization’s ISMS review meetings with top management.
Benchmark backup practices against industry standards and update controls accordingly.
Archive obsolete backup media securely and document destruction in compliance with retention policies.
