Enterprise tier is required for HSS (Host Security Service), baseline checks (CIS benchmarks), and ransomware protection. Basic tier provides only ECS vulnerability scanning.</li>\n<li>Vulnerability scanning covers: OS vulnerabilities (CVE-based), web CMS vulnerabilities (WordPress, Drupal, etc.), and image vulnerabilities for ACK container images.</li>\n<li>WAF protects HTTP/HTTPS traffic. Rule groups cover OWASP Top 10, bot management, and custom rules. IP whitelist bypass should require documented justification — undocumented bypasses are compliance gaps.</li>\n<li>Anti-DDoS Pro provides DDoS protection tiers: Basic (built-in, free), Standard, and Enhanced. Downgrade during an active attack is blocked by Alibaba Cloud — plan tier before attack, not during.</li>\n<li>Cloud Firewall: internet firewall controls north-south traffic (internet ↔ ECS/SLB). VPC firewall controls east-west traffic (VPC ↔ VPC or intra-VPC). Policy changes affect all instances in scope simultaneously — test in a non-production VPC first.</li>\n<li>NTA analyzes VPC flow logs for anomaly detection. Effective NTA requires VPC flow log collection configured to SLS.</li>\n<li>MLPS Level 3 mandates all of: boundary protection (Cloud Firewall + WAF), intrusion detection (Security Center HSS), and audit log (ActionTrail + SLS with 180-day retention).</li>\n</ul>\n<h2>Lean operating rules</h2>\n<ul>\n<li>Prefer official Alibaba Cloud documentation and live evidence over memory or inference.</li>\n<li>Separate confirmed facts from inference. If Security Center scan results, WAF rule state, or Cloud Firewall policy was not queried or shown, say so.</li>\n<li>Challenge WAF IP whitelist bypasses without documented justification, Security Center in Basic tier for MLPS Level 3 workloads, and Anti-DDoS tier mismatch with expected attack surface.</li>\n<li>Keep answers scoped, reversible, and explicit about blast radius and open questions.</li>\n<li>Load references only when needed; do not pull all deep guidance into short answers.</li>\n</ul>\n<h2>References</h2>\n<p>Load these only when needed:</p>\n<ul>\n<li><a href=\"references/workflow-and-output.md\">Workflow and output contract</a> — use when executing the full security hardening review, incident triage, or formatting the final answer.</li>\n<li><a href=\"references/official-sources.md\">Official sources</a> — use when grounding Alibaba Cloud Security Center, WAF, Anti-DDoS, or Cloud Firewall service behavior or checking the detailed source list.</li>\n</ul>\n<h2>Response minimum</h2>\n<p>Return, at minimum:</p>\n<ul>\n<li>the scoped target and evidence level,</li>\n<li>the Security Center tier and vulnerability/baseline findings,</li>\n<li>the WAF rule coverage and bypass gaps,</li>\n<li>the Cloud Firewall policy assessment (north-south and east-west),</li>\n<li>the MLPS 2.0 Level 3 technical control coverage assessment,</li>\n<li>the safest next actions with validation steps,</li>\n<li>the assumptions or blockers that prevent stronger conclusions.</li>\n</ul>\n","files":[{"path":"metadata.json","sizeBytes":1200,"isText":true},{"path":"references/official-sources.md","sizeBytes":720,"isText":true},{"path":"references/workflow-and-output.md","sizeBytes":1880,"isText":true},{"path":"SKILL.md","sizeBytes":4455,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
