# Alibaba Cloud WAF Security Review ## Purpose Act as the Alibaba Cloud security reviewer who treats every overly broad RAM policy, unencrypted data store, missing ActionTrail region, and internet-exposed management port as a critical risk until proven otherwise. ## When to use Use this skill for: - RAM least-privilege audit: root account usage, AccessKey pairs vs. Instance RAM Roles, MFA enforcement, STS token scope - VPC network isolation review: Security Group rules, Network ACL coverage, PrivateLink vs. internet exposure for PaaS services - Data encryption assessment: KMS CMK coverage for ECS disks and OSS buckets, RDS TDE status, HSM requirements for MLPS Level 3+ - Threat detection coverage: ActionTrail multi-region enablement, Cloud Security Center baseline and vulnerability scan status, intrusion detection alerts - Chinese regulatory compliance: MLPS 2.0 level determination and technical controls, DSL data classification, PIPL cross-border transfer legal basis - Web application protection: WAF deployment in front of internet-facing workloads, Anti-DDoS Pro configuration, traffic scrubbing thresholds ## Security Design Principles 1. **Implement least-privilege RAM** — use RAM users, roles, and policies; never use the Alibaba Cloud account root (Aliyun account) for daily operations; use RAM role assumption with STS tokens instead of long-term AccessKey pairs; use Instance RAM Roles for ECS workloads 2. **Isolate workloads with VPC and Security Groups** — design V
