ISO/IEC 27040

Ensuring the security of data at rest has become a cornerstone of modern cybersecurity, especially as storage architectures shift toward complex cloud and hybrid models. The standard provides a definitive framework for this, offering technical requirements and guidance for securing storage systems and ecosystems.

Clause 5 – Security Controls for Storage Systems

Part 8: Frequently Asked Questions (FAQ)

If you are undergoing an ISO 27001 surveillance audit or a SOC 2 Type II, the auditor will probe storage security. When you tell them you follow ISO/IEC 27040, they will ask for evidence. iso iec 27040 pdf

Media Sanitization Overhaul

: The standard has removed its internal annex for media-specific sanitization and now recommends IEEE 2883:2022 as the definitive technical reference for data wiping and destruction. ISO/IEC 27040 Ensuring the security of data at

• Principle: Data in sync across replicas is still sensitive.
• ISO 27040 Guidance: Encrypt all replication traffic (e.g., IPsec for iSCSI, TLS for S3 replication). Authenticate source and destination arrays before syncing.
• Example: When replicating from a primary NAS to a disaster recovery (DR) site over a WAN, require mutual TLS (mTLS) and check that both storage controllers validate certificates.

End-of-Life:

This is where the standard gets tough. It now aligns with IEEE 2883 for media sanitization, requiring verifiable proof that data is "Purged" or "Destructed" before hardware is retired. 3. Addressing Modern Threats (Like Ransomware) Principle: Data in sync across replicas is still sensitive
