Confidentiality

Confidentiality is a fundamental principle of information security, part of the CIA Triad (Confidentiality, Integrity, Availability). It is defined as the property that information is not made available or disclosed to unauthorized individuals, entities, or processes. In risk management, it is a primary control objective. Standards like ISO/IEC 27001:2022 establish it as a core goal. Regulations such as GDPR (Article 5(1)(f)) and Taiwan's Personal Data Protection Act mandate appropriate technical and organizational measures to ensure confidentiality. It differs from privacy, which is an individual's right to control their personal information; confidentiality is the mechanism used to protect that information from unauthorized disclosure.

Enterprises apply confidentiality through a multi-layered approach. First, through **Data Classification**, data is categorized based on sensitivity (e.g., Public, Internal, Confidential) to determine the required level of protection. Second, **Access Control** is implemented based on the Principle of Least Privilege (PoLP), using Role-Based Access Control (RBAC) to ensure employees can only access data necessary for their roles. Third, **Encryption** is applied to data at rest (in storage) and in transit (over networks) to render it unreadable if intercepted. For example, a global e-commerce company encrypts all customer payment data and uses strict access controls, reducing the risk of a data breach and achieving 100% compliance with PCI DSS audit requirements.

Taiwan enterprises often face three key challenges: 1. **Resource Constraints:** Small and medium-sized enterprises (SMEs) typically lack dedicated cybersecurity staff and budgets for advanced tools like Data Loss Prevention (DLP) systems. 2. **Legacy IT Systems:** Outdated infrastructure may not support modern security controls, such as strong encryption protocols or granular access logging, making it difficult to enforce confidentiality policies effectively. 3. **Cultural Resistance:** Employees may resist security measures they find inconvenient, such as multi-factor authentication (MFA) or strict password policies, leading to insecure workarounds. To overcome this, enterprises should adopt a risk-based approach to prioritize critical assets, plan phased system upgrades, and foster a strong security culture through continuous awareness training.
