Alibaba Cloud Data Security Center (DSC), originally known as SDDP (Sensitive Data Discovery and Protection), is an all-in-one cloud-native data security solution offered by Alibaba Cloud. It is designed to help organizations discover, classify, grade, and protect sensitive data across cloud-based data assets without requiring agent deployment. DSC uses built-in and customizable algorithms, along with machine learning and natural language processing (NLP), to automatically scan and classify both structured and unstructured data. It supports compliance with regulations including GDPR, Multi-Level Protection Scheme (MLPS) 2.0 Level 2, and MLPS 2.0 Level 3. The platform provides sensitive data de-identification using more than ten advanced algorithms, allowing organizations to safely use data in non-production environments such as development and testing. DSC also detects AccessKey pair leaks from GitHub and OSS buckets, provides data activity auditing with configurable audit rules, and monitors anomalous data flows and access patterns. A free edition is available offering baseline checks and classification and grading capabilities, while a paid commercial edition provides the full feature set. DSC integrates with Alibaba Cloud services including ApsaraDB RDS, Object Storage Service (OSS), MaxCompute, and Alibaba Cloud Data Mid-End, enabling centralized data security management across diverse cloud data sources.
