Alibabacloud Sas Overview

Alibaba Cloud Security Center (SAS) Overview Data Query Skill. Retrieves security score, asset status, risk governance, asset risk trends, and billing info....

Security Scan

The skill's requirements and instructions are consistent with an Alibaba Cloud SAS read-only overview query: it uses the Aliyun CLI and read-only RAM policies and does not ask for or exfiltrate credentials in the instructions.

Purpose & Capability

Name/description match the concrete CLI commands and APIs in SKILL.md and references (SAS, WAF, BssOpenApi). Required actions (multi-region queries, read-only billing/SAS/WAF data) are appropriate for an 'overview query' skill.

Instruction Scope

Runtime instructions are narrowly scoped to querying SAS/WAF/Billing data via the Aliyun CLI. The skill explicitly forbids reading or printing AK/SK and requires explicit user confirmation for parameters; it does not instruct reading unrelated system files or sending data to third-party endpoints.

Install Mechanism

This is instruction-only (no install spec). The included CLI installation guide points to official aliyuncli download URLs (alicdn.com) and recommends enabling automatic plugin installation; enabling auto-plugin-install means the CLI may download plugins at runtime — expected for this use-case but worth noting.

Credentials

The skill does not declare env vars or primary credentials, but it requires the user to have valid Alibaba Cloud credentials accessible to the Aliyun CLI. The provided RAM policy requests read-only actions across SAS/WAF/BSS (Resource: "*") — broad in resource scope but consistent with listing/overview queries. The skill's docs emphasize least-privilege and never asking for AK/SK in chat.

Persistence & Privilege

The skill does not request always:true, has no install, and does not modify other skills or global agent settings. It operates via ephemeral CLI commands executed with the user's configured credentials.

Assessment

This skill appears to do what it says: run Aliyun CLI commands to fetch SAS/WAF/billing overview data. Before installing or using it: (1) run it only from a machine you control (not share credentials in chat); (2) ensure your Aliyun CLI is v3.3.1+ and review the CLI download URLs; (3) prefer a RAM user with the listed read-only policies (least privilege) rather than root keys; (4) do not paste your AK/SK into the conversation — the skill explicitly forbids this; (5) be aware enabling the CLI's automatic plugin install will let the CLI download plugins at runtime; (6) confirm the agent asks you to approve Regions, BillingCycle, and other parameters before it runs any commands. If you want tighter control, run the documented commands yourself in your terminal rather than granting an agent autonomous access.

SAS Overview Data Query

Retrieves the 5 core modules of the Security Center (SAS) overview dashboard:

1. Security Overview — score, fixed vulns, baseline risk, handled alerts
2. Usage Info — service days, asset scale, uninstalled clients
3. Security Operations — risk governance (AI risk, CSPM, key config, system vulns), security protection (WAF blocks), security response
4. Asset Risk Trend — host/container/cloud product risk ratios + trend chart
5. Billing & Subscription — post-pay switches, subscription validity, bills

Execution Scope: Each module and data item can be queried independently. Match the scope to the user's request:

• Single data item — e.g., "What is my security score?" → only command 1a
• Single module — e.g., "Show asset risk trend" → all of Module 4
• Full overview — e.g., "SAS overview" → all 5 modules

Architecture: SAS + WAF + BssOpenApi

Prerequisites

Pre-check: Aliyun CLI >= 3.3.1 required Run aliyun version to verify >= 3.3.1. If not installed or version too low, see references/cli-installation-guide.md for installation instructions. Then run aliyun configure set --auto-plugin-install true to enable automatic plugin installation.

Install required CLI plugins:

aliyun plugin install --names aliyun-cli-sas aliyun-cli-waf-openapi aliyun-cli-bssopenapi

Pre-check: Alibaba Cloud Credentials Required

Security Rules:

• NEVER read, echo, or print AK/SK values (e.g., echo $ALIBABA_CLOUD_ACCESS_KEY_ID is FORBIDDEN)
• NEVER ask the user to input AK/SK directly in the conversation or command line
• NEVER use aliyun configure set with literal credential values
• ONLY use aliyun configure list to check credential status

aliyun configure list

Check the output for a valid profile (AK, STS, or OAuth identity).

If no valid profile exists, STOP here.

1. Obtain credentials from Alibaba Cloud Console
2. Configure credentials outside of this session (via aliyun configure in terminal or environment variables in shell profile)
3. Return and re-run after aliyun configure list shows a valid profile

Parameters

IMPORTANT: Parameter Confirmation — Before executing any command or API call, ALL user-customizable parameters (e.g., RegionId, WAF InstanceId, BillingCycle, etc.) MUST be confirmed with the user. Do NOT assume or use default values without explicit user approval.

Parameter	Required	Description	Default
Regions	Yes	SAS regions to aggregate data from	cn-shanghai, ap-southeast-1
WAF Instance ID	Auto-fetched	Auto-fetched via WAF DescribeInstance for DescribeFlowChart	Auto
Billing Cycle	Only for billing	Billing month in YYYY-MM format	Current month
Time Range	No	Days of history for score/trend queries	7 (last 7 days)

RAM Permissions

See references/ram-policies.md for the full RAM policy JSON.

Required: AliyunYundunSASReadOnlyAccess, AliyunWAFReadOnlyAccess, AliyunBSSReadOnlyAccess.

Core Workflow

Based on the user's query, execute the relevant module(s) below. Each module — and each data item within a module — can be executed independently. For APIs marked multi-region, always query both cn-shanghai and ap-southeast-1, then sum the results.

Module 1: Security Overview

# 1a. Security Score (region-agnostic)
aliyun sas describe-secure-suggestion --cal-type home_security_score --user-agent AlibabaCloud-Agent-Skills
# Extract: Score field from response as current security score
#
# NOTE: DescribeScreenScoreThread is currently unavailable (CalType not supported).
# Once supported, switch to the command below for score + historical trend:
#   START=$(python3 -c "import time; print(int((time.time()-86400*7)*1000))")
#   END=$(python3 -c "import time; print(int(time.time()*1000))")
#   aliyun sas describe-screen-score-thread \
#     --cal-type home_security_score \
#     --start-time "$START" --end-time "$END" \
#     --user-agent AlibabaCloud-Agent-Skills
#   Extract: Data.SocreThread[-1] = current score, full SocreThread list = historical trend

# 1b. Fixed Vulnerabilities (multi-region: sum FixTotal)
aliyun sas describe-vul-fix-statistics --region cn-shanghai --user-agent AlibabaCloud-Agent-Skills
aliyun sas describe-vul-fix-statistics --region ap-southeast-1 --user-agent AlibabaCloud-Agent-Skills

# 1c. Baseline Risk Statistics (multi-region: sum each Summary field)
aliyun sas get-check-risk-statistics --region cn-shanghai --user-agent AlibabaCloud-Agent-Skills
aliyun sas get-check-risk-statistics --region ap-southeast-1 --user-agent AlibabaCloud-Agent-Skills
# Extract: Summary.RiskCheckCnt, Summary.RiskWarningCnt,

Module 2: Usage Info

# 2a. Service Duration + Subscription (region-agnostic)
aliyun sas describe-version-config --user-agent AlibabaCloud-Agent-Skills
# Check IsPaidUser first:
#   IsPaidUser == true  → Extract CreateTime, calculate (now - CreateTime) as days
#   IsPaidUser == false → Service duration not applicable, display N/A
# Extract: ReleaseTime → subscription expiry (pre-pay only)

# 2b. Host Asset Info (multi-region: sum TotalCount and Cores)
aliyun sas describe-cloud-center-instances \
  --region cn-shanghai --machine-types ecs --current-page 1 --page-size 20 \
  --user-agent AlibabaCloud-Agent-Skills
aliyun sas describe-cloud-center-instances \
  --region ap-southeast-1 --machine-types ecs --current-page 1 --page-size 20 \
  --user-agent AlibabaCloud-Agent-Skills
# Extract: PageInfo.TotalCount (sum across regions) for host count
# Extract: Sum all instances' Cores field for total core count
# Optionally list host details if user requests

# 2c. Uninstalled Clients (multi-region: sum TotalCount)
aliyun sas list-uninstall-aegis-machines --region cn-shanghai --current-page 1 --page-size 1 --user-agent AlibabaCloud-Agent-Skills
aliyun sas list-uninstall-aegis-machines --region ap-southeast-1 --current-page 1 --page-size 1 --user-agent AlibabaCloud-Agent-Skills

Module 3: Security Operations

3a. Risk Governance (region-agnostic, single API call)

aliyun sas describe-secure-suggestion --cal-type home_security_score --user-agent AlibabaCloud-Agent-Skills
# Process Suggestions[] by SuggestType:
#   SS_AI_RISK → AI Risk (SubType not fixed, e.g. SSI_AISPM_RISK; analyze Description for unknown SubTypes)
#     Aggregate riskCount by region
#   SS_SAS_CLOUD_HC → CSPM risks (aggregate by HIGH/MEDIUM/LOW and region)
#     Cloud: SSI_SAS_CLOUD_HC_HIGH / MEDIUM / LOW
#     Host:  SSI_SAS_HOST_HC_HIGH / MEDIUM / LOW
#   SS_KEY_CONFIG → Key Config (SubType not fixed; analyze Description for unknown SubTypes)
#     Aggregate RiskCount by region
#   SS_SAS_SYS_VUL → System Vulns (aggregate by HIGH/MEDIUM/LOW and region)
#     SSI_SAS_SYS_VUL_HIGH / SSI_SAS_SYS_VUL_MEDIUM / SSI_SAS_SYS_VUL_LOW

3b. Security Protection — WAF Blocks (multi-region, two-step)

# Step 1: Get WAF Instance ID (per region)
aliyun waf-openapi describe-instance --region cn-shanghai --user-agent AlibabaCloud-Agent-Skills
aliyun waf-openapi describe-instance --region ap-southeast-1 --user-agent AlibabaCloud-Agent-Skills
# Extract: InstanceId from each region's response

# Step 2: Query WAF flow chart using each region's InstanceId
START_SEC=$(python3 -c "import time; print(int(time.time()-86400*7))")
aliyun waf-openapi describe-flow-chart \
  --region cn-shanghai \
  --instance-id "<InstanceId from cn-shanghai>" \
  --start-timestamp "$START_SEC" \
  --interval 3600 \
  --user-agent AlibabaCloud-Agent-Skills
aliyun waf-openapi describe-flow-chart \
  --region ap-southeast-1 \
  --instance-id "<InstanceId from ap-southeast-1>" \
  --start-timestamp "$START_SEC" \
  --interval 3600 \
  --user-agent AlibabaCloud-Agent-Skills
# Sum all WafBlockSum values from both regions

3c. Security Response

# Currently no data (N/A)

  --region cn-shanghai \
  --user-agent AlibabaCloud-Agent-Skills
# Extract: GroupedFields.InstanceCountTotal, GroupedFields.InstanceRiskCountTotal
# Repeat for ap-southeast-1, sum both

# 4d. Trend Chart Data (multi-region)
START_MS=$(python3 -c "import time; print(int((time.time()-86400*7)*1000))")
END_MS=$(python3 -c "import time; print(int(time.time()*1000))")
aliyun sas describe-chart-data \
  --region cn-shanghai \
  --chart-id CID_ASSET_RISK_TREND \
  --report-id -1 \
  --time-start "$START_MS" --time-end "$END_MS" \
  --user-agent AlibabaCloud-Agent-Skills
# Returns time series: host / container / cloud risk counts

Module 5: Billing & Subscription

# 5a. Query billing mode (from Module 2a response, can reuse cached result)
aliyun sas describe-version-config --user-agent AlibabaCloud-Agent-Skills
# Check IsPaidUser field to determine billing mode:
#
# If IsPaidUser == true → Pre-pay (subscription) user:
#   Extract CreateTime → purchase date (convert ms timestamp to YYYY-MM-DD)
#   Extract ReleaseTime → expiry date (convert ms timestamp to YYYY-MM-DD)
#
# If IsPaidUser == false → Post-pay user:
#   Extract PostPayModuleSwitch (JSON string — must parse)
#   Map codes to product names using the table below:
#     POST_HOST → Host and Container Security
#     VUL → Vulnerability Fixing
#     CSPM → CSPM
#     CTDR → Agentic SOC
#     AGENTLESS → Agentless Detection
#     SERVERLESS → Serverless Asset Protection
#     RASP → Application Protection
#     SDK → Malicious File Detection
#     CTDR_STORAGE → Log Management
#     ANTI_RANSOMWARE → Anti-ransomware
#   Value 1 = Enabled, 0 = Disabled

# 5c. Billing Details (try each region, skip on permission error)
BILLING_CYCLE=$(date +%Y-%m)
aliyun bssopenapi query-bill \
  --region cn-shanghai \
  --billing-cycle "$BILLING_CYCLE" --product-code sas \
  --user-agent AlibabaCloud-Agent-Skills
# If the above returns a permission error, skip cn-shanghai and continue

aliyun bssopenapi query-bill \
  --region ap-southeast-1 \
  --billing-cycle "$BILLING_CYCLE" --product-code sas \
  --user-agent AlibabaCloud-Agent-Skills
# If the above returns a permission error, skip ap-southeast-1 and continue
# Aggregate results from whichever regions succeeded

Product Code Mapping

Product Name	Code	Status Values

Vulnerability Fixing	VUL	1: Enabled, 0: Disabled
CSPM	CSPM	1: Enabled, 0: Disabled
Agentic SOC	CTDR	1: Enabled, 0: Disabled
Agentless Detection	AGENTLESS	1: Enabled, 0: Disabled
Serverless Asset Protection	SERVERLESS	1: Enabled, 0: Disabled
Application Protection	RASP	1: Enabled, 0: Disabled
Malicious File Detection	SDK	1: Enabled, 0: Disabled
Log Management	CTDR_STORAGE	1: Enabled, 0: Disabled
Anti-ransomware	ANTI_RANSOMWARE	1: Enabled, 0: Disabled

Data Processing Rules

1. Multi-region aggregation: APIs requiring regions must query cn-shanghai + ap-southeast-1 separately, then sum the numeric results.
2. Timestamps: SAS APIs use millisecond timestamps. WAF APIs use second timestamps.
3. PostPayModuleSwitch: Is a JSON string — must JSON.parse() / json.loads() before reading.
4. Score extraction: Use Score field from DescribeSecureSuggestion response as current score. Note: DescribeScreenScoreThread is currently unavailable (CalType not supported); once supported, switch to using the last element of Data.SocreThread[] as current score and the full list as historical trend.
5. N/A fields: Security Response Events have no data — display "N/A".
6. Timestamp formatting: Convert ms timestamps to YYYY-MM-DD HH:mm:ss for display.

Success Verification

See references/verification-method.md for step-by-step verification commands.

Cleanup

This skill is read-only (query operations only). No resources are created, so no cleanup is needed.

Best Practices

1. Always query both cn-shanghai and ap-southeast-1 for multi-region APIs before aggregating.
2. Cache the DescribeVersionConfig response — it is used by both Module 2 and Module 5.
3. Use --cli-query (JMESPath) to extract specific fields and reduce output noise.
4. Set --page-size 1 when only TotalCount is needed (e.g., ListUninstallAegisMachines).
5. WAF DescribeFlowChart requires a valid WAF instance ID — auto-fetch via DescribeInstance first; query both cn-shanghai and ap-southeast-1.
6. Billing queries (QueryBill) require --region — try each region (cn-shanghai, ap-southeast-1) in turn; skip any region that returns a permission error.
7. All timestamps returned by SAS are in milliseconds — divide by 1000 for human-readable conversion.
