Establish criteria for excluding systems from regular backup based on risk acceptance decisions documented in the risk treatment plan.
Integrate backup planning into the organization’s risk assessment methodology as part of control implementation.
Ensure backup policies are referenced in ISMS documentation and reviewed during internal audits.
Coordinate with legal and compliance teams to identify data subject to statutory retention requirements that influence backup schedules.
Document exceptions to backup coverage with formal risk treatment justifications approved by risk owners.

Module 2: Designing a Tiered Backup Architecture for Diverse Systems

Classify systems into backup tiers (e.g., critical, essential, non-essential) based on business criticality and RTO/RPO.
Select appropriate backup methods (full, incremental, differential) per system type considering storage efficiency and restore complexity.
Implement application-consistent backups for databases using VSS, RMAN, or native tools to ensure transactional integrity.
Design snapshot strategies for virtualized environments balancing performance impact and recovery granularity.
Configure backup frequency for email systems to meet legal hold and e-discovery obligations.
Implement agentless vs. agent-based backup approaches based on system manageability and security constraints.
Design backup workflows for SaaS applications using API-based export tools or third-party integration platforms.
Segment backup traffic onto isolated network VLANs to reduce exposure to lateral movement during data transfer.

Module 3: Securing Backup Data at Rest and in Transit

Enforce TLS 1.2+ for all backup data transmissions between source systems and backup repositories.
Implement AES-256 encryption for backup media, ensuring keys are managed through a centralized key management system (KMS).
Define access control policies for backup storage that follow the principle of least privilege and separation of duties.
Apply write-once-read-many (WORM) configurations on storage targets to prevent tampering or ransomware encryption.
Conduct periodic audits of backup encryption configurations to verify compliance with organizational policy.
Protect backup catalogs and metadata with the same controls applied to primary data repositories.
Restrict physical access to offsite backup tapes or drives using access logs and biometric controls.
Enforce multi-factor authentication for administrative access to backup management consoles.

Module 4: Managing Backup Media and Offsite Storage

Define retention periods for backup media based on data classification and regulatory requirements.
Implement a secure tape rotation scheme (e.g., GFS) with documented chain of custody for offsite transfers.
Select third-party vault providers based on ISO 27001 certification and audit rights in service contracts.
Conduct periodic inventory checks of physical backup media to detect loss or unauthorized duplication.
Define destruction procedures for expired backup media using degaussing or physical shredding with certification.
Track geographic location of offsite backups to ensure compliance with data sovereignty laws.
Validate transport security for backup media using tamper-evident packaging and encrypted containers.
Establish redundancy by storing duplicate backup sets in geographically separate locations.

Module 5: Integrating Backup Controls into Change Management

Require backup configuration updates to be submitted through the formal change advisory board (CAB) process.
Update backup job definitions following any system migration, reconfiguration, or decommissioning.
Verify that new systems are included in backup schedules before production go-live.
Document backup impact assessments for changes to network topology or firewall rules.
Review backup scripts and automation workflows during change implementation for unintended side effects.
Ensure backup exclusion lists are reviewed and re-authorized annually or after major infrastructure changes.
Update backup monitoring alerts when systems are restructured or renamed.
Coordinate with cloud provisioning teams to ensure IaC templates include backup agent installation and registration.

Module 6: Monitoring, Alerting, and Incident Response for Backup Failures

Define escalation paths for failed backup jobs based on system criticality and duration of failure.
Configure monitoring tools to detect job failures, missed schedules, and abnormal backup sizes.
Integrate backup event logs into SIEM systems for correlation with security incidents.
Investigate backup failures within SLA timeframes and document root causes in the incident management system.
Trigger incident response procedures when backup tampering or deletion is detected.
Validate that monitoring covers both on-premises and cloud-based backup operations.
Test alert delivery mechanisms quarterly to ensure notification channels remain functional.
Use backup success/failure trends to identify systemic issues such as storage exhaustion or credential expiry.

Module 7: Conducting Backup Testing and Recovery Drills

Schedule regular recovery tests for critical systems aligned with business continuity testing cycles.
Perform full-system restores for high-availability environments to validate bare-metal recovery capabilities.
Test recovery of individual files and databases to verify granularity and usability.
Document recovery times and compare against RTOs to identify performance gaps.
Include backup recovery steps in tabletop exercises for disaster recovery scenarios.
Rotate personnel conducting recovery tests to maintain organizational readiness.
Validate data integrity post-recovery using checksums or application-level verification.
Update runbooks and recovery procedures based on findings from test outcomes.

Module 8: Vendor and Third-Party Backup Service Governance

Assess third-party backup providers against ISO 27001 certification and audit reports (e.g., SOC 2).
Negotiate contractual clauses specifying data ownership, access rights, and breach notification timelines.
Verify that vendor backup operations are included in the organization’s supplier risk assessment process.
Conduct on-site audits or request independent audit reports for high-risk vendors.
Ensure vendor access to backup systems is logged and reviewed as part of privileged access monitoring.
Define exit strategies including data extraction formats and timelines in case of contract termination.
Validate that vendor systems enforce encryption and access controls equivalent to internal standards.
Require vendors to participate in recovery testing as part of service level agreement (SLA) validation.

Module 9: Audit Readiness and Evidence Collection for Backups

Prepare logs of successful and failed backup jobs for auditor review during certification cycles.
Maintain evidence of annual backup policy review and approval by information security management.
Archive records of recovery test results, including timestamps, personnel involved, and outcomes.
Provide documentation showing alignment between backup configurations and risk treatment decisions.
Generate reports demonstrating compliance with retention periods for regulated data sets.
Preserve audit trails of access to backup management consoles for forensic investigations.
Compile evidence of encryption usage across all backup media and transmission channels.
