Key technologies for data security compliance include:

  1. Encryption – Protects data at rest and in transit using algorithms like AES-256. For example, encrypting sensitive customer data stored in databases ensures confidentiality even if unauthorized access occurs. Tencent Cloud offers Tencent Cloud KMS (Key Management Service) for secure key management and encryption.

  2. Access Control – Enforces least-privilege principles through role-based access control (RBAC) or attribute-based access control (ABAC). For instance, limiting database access to only authorized personnel reduces insider threats. Tencent Cloud’s CAM (Cloud Access Management) enables fine-grained permission control.

  3. Data Loss Prevention (DLP) – Monitors and blocks unauthorized data transfers. DLP tools can detect sensitive information like credit card numbers in emails or files. Tencent Cloud’s Data Security Center provides DLP capabilities to safeguard data.

  4. Audit Logging & Monitoring – Tracks user activities and system changes for compliance audits. For example, logging all database queries helps detect anomalies. Tencent Cloud’s CloudAudit records API calls and resource changes for compliance tracking.

  5. Tokenization – Replaces sensitive data with non-sensitive tokens, reducing exposure. Payment systems often use tokenization to secure cardholder data. Tencent Cloud’s Tencent Cloud Payment Encryption supports tokenization for financial data.

  6. Compliance Automation Tools – Simplifies adherence to regulations like GDPR or HIPAA. Automated tools scan configurations and flag non-compliant settings. Tencent Cloud’s Compliance Center helps assess and maintain regulatory compliance.

  7. Zero Trust Architecture – Verifies every access request, regardless of origin. For example, multi-factor authentication (MFA) ensures identity validation before granting access. Tencent Cloud supports MFA integration across services.

  8. Data Residency & Sovereignty Controls – Ensures data storage complies with regional laws. For example, storing EU customer data within EU data centers meets GDPR requirements. Tencent Cloud provides region-specific data centers to meet localization needs.
