Distributed storage security architecture design for private domain traffic pool?

Designing a distributed storage security architecture for a private domain traffic pool involves several key components to ensure data confidentiality, integrity, and availability. Here’s a breakdown of the architecture and an example:

Key Components:

1. Access Control: Implement strict access controls to ensure only authorized users and services can access the data. This can be achieved through role-based access control (RBAC) or attribute-based access control (ABAC).

2. Encryption: Encrypt data at rest and in transit. Use strong encryption algorithms like AES for data at rest and TLS for data in transit.

3. Data Segmentation: Divide the data into smaller segments and store them across different nodes to prevent a single point of failure and to enhance security.

4. Replication and Backup: Replicate data across multiple nodes and regularly back up the data to prevent data loss in case of hardware failures or security breaches.

5. Intrusion Detection and Prevention Systems (IDPS): Deploy IDPS to monitor and detect any suspicious activities or potential security threats in real-time.

6. Audit Logs: Maintain detailed audit logs to track all access and modifications to the data, which can be useful for forensic analysis in case of a security incident.

Example:

Consider a private domain traffic pool for an e-commerce platform. The platform stores sensitive customer data, including personal information and transaction details.

• Access Control: Only authorized employees with specific roles (e.g., customer service representatives, account managers) can access customer data.
• Encryption: All customer data is encrypted using AES-256 when stored on the distributed storage system and transmitted using TLS.
• Data Segmentation: Customer data is segmented into smaller chunks and stored across multiple nodes in different geographical locations.
• Replication and Backup: Data is replicated across three nodes in different data centers, and backups are taken daily and stored in a separate secure location.
• IDPS: An IDPS is deployed to monitor network traffic and detect any unauthorized access attempts or suspicious activities.
• Audit Logs: Detailed audit logs are maintained to track all access and modifications to customer data.

Recommendation for Cloud Services:

For implementing such an architecture, consider using Tencent Cloud’s services like:

• Tencent Cloud COS (Cloud Object Storage): Offers secure and reliable object storage with encryption at rest and in transit.
• Tencent Cloud TDSQL: Provides a distributed relational database with strong security features, including encryption and access control.
• Tencent Cloud Security Center: Offers comprehensive security solutions, including intrusion detection and prevention, and security auditing.

This architecture ensures that the private domain traffic pool is secure, scalable, and resilient to various threats and failures.
