Questions & Answers

What is Data Usability?

In information security and risk management, the core concept of "Data Usability" is "Availability," which means ensuring authorized users have timely and uninterrupted access to and use of information and associated assets. It is one of the three pillars of information security (Confidentiality, Integrity, Availability). According to ISO/IEC 27001, availability is "the property of being accessible and usable upon demand by an authorized entity." For a PIMS (Privacy Information Management System), ensuring the availability of personal data is crucial.

Why do Taiwanese companies need to prioritize it?

If Taiwanese companies fail to ensure the availability of customer or operational data, it can lead to business interruption and reputational damage. More seriously, if personal data is involved, they face pressure from the Personal Data Protection Act (PDPA). Under recent amendments, failure to take appropriate security measures leading to a data breach (which includes unavailability) can result in fines of up to NT$15 million for severe cases, along with civil liability. For core supply chain enterprises, such as those in the semiconductor and financial industries, operational continuity and data availability are fundamental market and customer requirements.

Which ISO standards or international regulations are directly related?

Data Usability (Availability) is directly related to several standards: 1. **ISO/IEC 27001:2022**: The international standard for information security management systems. Its Annex A includes numerous controls to ensure availability, such as A.5.30 (ICT readiness for business continuity) and A.8.14 (Redundancy). 2. **ISO/IEC 27701:2019**: As a privacy extension to ISO 27001, it requires applying security controls (including availability) to the protection of Personally Identifiable Information (PII). 3. **Taiwan's Personal Data Protection Act (PDPA)**: Article 27 requires non-governmental agencies to adopt appropriate security measures to prevent personal data from being stolen, altered, damaged, destroyed, or disclosed, ensuring data integrity and availability.
