Introduction

• Guidelines for protecting data where it lives (HDDs, SSDs, tapes, cloud buckets).
• Control objectives for storage networks, appliances, and virtualization.
• Risk-based approaches to encryption, key management, data retention, and sanitization.

Technical areas covered

• Storage architectures: Guidance on securing different topologies (DAS, SAN, NAS, object) and architectures (scale-out, scale-up, converged/hyperconverged).
• Access control and authentication: Strong authentication for administrative and user access; role-based access control (RBAC); multi-factor authentication for critical functions.
• Encryption and key management: Requirements and recommendations for encrypting data-at-rest and key lifecycle management (generation, distribution, storage, rotation, revocation). Distinguish between client-side, server-side, and storage-controller encryption.
• Data integrity controls: Checksums, hashing, digital signatures, and mechanisms to detect and prevent silent data corruption (bit rot); periodic integrity verification and repair processes.
• Immutability and write-once-read-many (WORM): When to use immutable storage and append-only controls for logs, archives, and regulatory retention.
• Backup, replication, snapshots: Secure backup architecture, secure replication channels, retention policies, secure handling of media and replication targets; validating backup integrity and restorability.
• Storage media handling and disposal: Secure sanitation, cryptographic erasure, physical destruction policies for decommissioned drives and media.
• Logging, monitoring, and audit: Storage-access logging, storage-system event monitoring, tamper-evident logs, and integration with SIEM and incident response.
• Network security for storage: Segmentation, isolation (management vs. data planes), encryption in transit for storage protocols, protection of management interfaces.
• Virtualization and multi-tenancy: Isolation controls, tenant separation, secure provisioning, and hypervisor/storage-controller hardening for virtualized and cloud environments.
• Cloud and service-provider considerations: Shared-responsibility models, validating provider controls, contractual and SLA considerations, encryption and key control strategies when using external providers.
• Supply chain and firmware: Firmware integrity, secure update processes, vulnerability management for storage controllers and appliances.
• Operational practices: Secure configuration baselines, patching, change management, backup testing, incident response procedures specific to storage incidents.

Relationship to ISO 27001:2022

If you are an ISO 27001 certified organization, Annex A of 27001 now includes specific references to storage controls. ISO 27040 acts as the implementation guide for those controls. For example: iso iec 27040 pdf
