What Is Cloud Trace Service?

Updated at: Apr 28, 2020 GMT+08:00

The log audit module is a core component necessary for information security audit and an important information system providing security risk management and control for enterprises and public institutions. As information systems migrate to the cloud, information and data security management departments around the world, including the Standardization Administration of the People's Republic of China/Technical Committee (SAC/TC), have released multiple standards, such as ISO IEC27000, GB/T 20945-2013, COSO, COBIT, ITIL, and NISTSP800.

Cloud Trace Service (CTS) is a log audit service for Huawei cloud security. It allows you to collect, store, and query resource operation records. You can use these records to perform security analysis, track resource changes, audit compliance, and locate faults.

CTS provides the following functions:
  • Trace recording: CTS records operations performed on the management console or by calling APIs, as well as operations triggered by each interconnected service.
  • Trace query: Operation records of the last seven days can be queried on the management console from multiple dimensions, such as the trace type, trace source, resource type, search by, operator and trace status.
  • Trace transfer: Traces are transferred to Object Storage Service (OBS) buckets on a regular basis for long-term storage. In this process, traces are compressed into trace files by service.
  • Trace file encryption: Trace files are encrypted using keys provided by Data Encryption Workshop (DEW) during transfer.
