In the financial industry, log auditing has stringent requirements due to regulatory compliance, security, and risk management needs. Key special requirements include:
Comprehensive Data Capture: Logs must record all critical operations, including user access, transactions, system changes, and error events. For example, every login attempt, fund transfer, or database modification should be logged with timestamps and user IDs.
Immutable Storage: Logs must be tamper-proof to ensure authenticity. Financial institutions often use write-once-read-many (WORM) storage or blockchain-based solutions to prevent alteration. Tencent Cloud's Cloud Audit (CA) service provides immutable log storage with timestamping and integrity verification.
Real-Time Monitoring & Alerting: Suspicious activities (e.g., multiple failed logins or large transactions) must trigger instant alerts. Tencent Cloud's Log Service (CLS) supports real-time log analysis and integrates with alarm systems for proactive monitoring.
Regulatory Compliance: Logs must adhere to standards like PCI-DSS, SOX, or GDPR. For instance, financial firms must retain logs for years and provide them for audits. Tencent Cloud helps meet compliance by offering long-term log retention and audit-ready reports.
Granular Access Control: Only authorized personnel should access logs. Role-based access control (RBAC) ensures separation of duties. Tencent Cloud's CAM (Cloud Access Management) enables fine-grained permission management for log data.
High Availability & Disaster Recovery: Log systems must be resilient to failures. Tencent Cloud's multi-region backup and high-availability architecture ensure log data is always accessible.
Example: A bank using Tencent Cloud can leverage CLS to aggregate logs from payment systems, CA to track admin actions, and CAM to restrict log access, ensuring compliance with financial regulations.
