To prevent leakage of sensitive data in cloud storage, implement the following measures:
Encryption: Encrypt data both at rest and in transit. Use strong encryption algorithms like AES-256 for stored data and TLS for data in transit. Tencent Cloud provides KMS (Key Management Service) to manage encryption keys securely.
Access Control: Apply the principle of least privilege. Use role-based access control (RBAC) to restrict access to sensitive data. Tencent Cloud’s CAM (Cloud Access Management) allows fine-grained permission management.
Data Masking & Tokenization: Replace sensitive data with tokens or masked values in non-production environments. This reduces exposure while maintaining usability.
Regular Auditing & Monitoring: Enable logging and monitoring to detect unauthorized access attempts. Tencent Cloud’s CASB (Cloud Access Security Broker) solution helps monitor data access and detect anomalies.
Secure API Access: Use API gateways with authentication (e.g., OAuth 2.0) to prevent unauthorized API calls. Tencent Cloud’s API Gateway ensures secure and controlled access to cloud services.
Data Backup & Recovery: Regularly back up data and test recovery procedures to prevent data loss from leaks or ransomware. Tencent Cloud’s CBS (Cloud Block Storage) and COS (Cloud Object Storage) offer reliable backup solutions.
Employee Training: Educate employees on data security best practices to prevent accidental leaks, such as phishing or mishandling credentials.
Example: A financial company stores customer records in Tencent Cloud COS with KMS encryption, restricts access via CAM, and monitors logs for suspicious activity.
