ISO/IEC 27040:2015 and Data Erasure

Key Requirements of the Standard

Definition and scope: This aspect covers the need for effective storage security management, including the identification of storage assets and data classification. The importance of protecting data at rest, in transit, and during deletion processes is emphasized.
Implementation: Organizations must develop and implement policies and procedures that ensure the protection of stored information, from data encryption to physical and logical access control.

Definition and scope: ISO/IEC 27040:2015 specifies the requirements for the sanitization of information, ensuring that data is deleted so that it cannot be recovered or reconstructed.
Implementation: Secure erasure and media destruction methods must be established that meet international sanitation standards, ensuring that sensitive information is irretrievable once it is decided to delete it.

The standard requires regular audits and security assessments to verify the effective implementation of storage security policies and controls.
These reviews should be properly documented, providing records that demonstrate compliance with storage security procedures and the effectiveness of data sanitization measures.

Documentation and audit records serve as key evidence during compliance and certification assessments. This includes evidence of proper handling and secure deletion of stored information, as well as the implementation of access controls and encryption.
Maintaining detailed and up-to-date documentation is essential to demonstrate compliance with ISO/IEC 27040:2015 and to support continuous improvement of storage security practices.
