: The official PDF for a single-user license of ISO/IEC 27040:2024 typically costs between CHF 150 and CHF 250 (Swiss Francs), though prices vary by region and reseller.

: Utilizing symmetric encryption (typically AES-256) to secure data on physical drives, block storage, and object stores. iso iec 27040 pdf

Encryption is a foundational control within ISO/IEC 27040. The standard provides comprehensive guidance on:

On January 26, 2024, ISO officially released the second edition of the standard, replacing the first edition from 2015. The new version represents a significant evolution in storage security guidance. If you are tasked with aligning your IT

: Apply the principle of least privilege. Only authorized servers and users should have visibility into specific storage targets.

This standard is essential because standard ISO/IEC 27002 controls provide only limited guidance on the specifics of storage security. Key Components of ISO/IEC 27040 The standard covers: The standard provides comprehensive guidance on: On January

The standard addresses vulnerabilities unique to Storage Area Networks (SANs). For Fibre Channel (FC) networks, it recommends strict switch authentication and fabric-binding controls. For iSCSI environments, it mandates the use of Challenge Handshake Authentication Protocol (CHAP) and network-level encryption to prevent eavesdropping on standard Ethernet lines. Cloud and Virtualized Storage

ISO/IEC 27040 focuses on securing the paths between servers and storage devices (e.g., Fibre Channel fabric security or securing iSCSI traffic). 4. Backups and Disaster Recovery

For organizations not currently using an ISMS, the first recommended step is to establish an ISO/IEC 27001-aligned program and then incorporate ISO/IEC 27040 to address the specific technical controls for storage.

: Hardening file-sharing protocols like NFS (Network File System) and SMB/CIFS (Server Message Block) using strong authentication and transport-layer encryption (SMB3/NFSv4 TLS). 3. Data Encryption Architecture
