AWS Inspector Management Skill
Analyze and manage AWS Inspector v2 vulnerability scanning, findings, and coverage.
MANDATORY: Discovery-First Pattern
Always check coverage and account status before querying findings.
Phase 1: Discovery
#!/bin/bash
export AWS_PAGER=""
echo "=== Inspector Account Status ==="
aws inspector2 batch-get-account-status --output text \
--query 'accounts[].[accountId,state.status,resourceState.ec2.status,resourceState.ecr.status,resourceState.lambda.status]' 2>/dev/null
echo ""
echo "=== Coverage Summary ==="
aws inspector2 list-coverage-statistics --output text \
--query 'countsByGroup[].[groupKey,counts]' 2>/dev/null
echo ""
echo "=== Coverage Details ==="
aws inspector2 list-coverage --output text \
--query 'coveredResources[].[resourceType,resourceId,scanStatus.statusCode,scanType]' 2>/dev/null | head -20
echo ""
echo "=== Finding Counts by Severity ==="
aws inspector2 list-finding-aggregations --aggregation-type SEVERITY --output text \
--query 'responses[].[severityCounts]' 2>/dev/null
Phase 2: Analysis
#!/bin/bash
export AWS_PAGER=""
echo "=== Critical Findings ==="
aws inspector2 list-findings \
--filter-criteria '{"severity":[{"comparison":"EQUALS","value":"CRITICAL"}]}' \
--max-results 10 --output text \
--query 'findings[].[title,severity,status,type,resourceType]' 2>/dev/null | head -15
echo ""
echo "=== High Severity Findings ==="
aws inspector2 list-findings \
--filter-criteria '{"severity":[{"comparison":"EQUALS","value":"HIGH"}]}' \
--max-results 10 --output text \
--query 'findings[].[title,severity,resourceType,firstObservedAt]' 2>/dev/null | head -15
echo ""
echo "=== Findings by Resource Type ==="
aws inspector2 list-finding-aggregations --aggregation-type RESOURCE_TYPE --output text \
--query 'responses[]' 2>/dev/null | head -10
echo ""
echo "=== Findings by Package ==="
aws inspector2 list-finding-aggregations --aggregation-type PACKAGE --output text \
--query 'responses[:10]' 2>/dev/null
echo ""
echo "=== ECR Image Findings ==="
aws inspector2 list-finding-aggregations --aggregation-type IMAGE_LAYER --output text \
--query 'responses[:10]' 2>/dev/null
echo ""
echo "=== Suppression Rules ==="
aws inspector2 list-filters --output text \
--query 'filters[].[name,arn,action,description]' 2>/dev/null | head -10
echo ""
echo "=== Delegated Admin ==="
aws inspector2 list-delegated-admin-accounts --output text \
--query 'delegatedAdminAccounts[].[accountId,status]' 2>/dev/null
echo ""
echo "=== Members ==="
aws inspector2 list-members --output text \
--query 'members[].[accountId,relationshipStatus]' 2>/dev/null | head -10
Output Format
- Target ≤50 lines per output
- Use
--output text --query for all commands
- Tab-delimited fields: Severity, Title, ResourceType, Status
- Aggregate findings by severity and resource type
- Never dump full vulnerability descriptions -- show title and severity only
Anti-Hallucination Rules
- NEVER assume resource names — always discover via CLI/API in Phase 1 before referencing in Phase 2.
- NEVER fabricate metric names or dimensions — verify against the service documentation or
--help output.
- NEVER mix CLI commands between service versions — confirm which version/API you are targeting.
- ALWAYS use the discovery → verify → analyze chain — every resource referenced must have been discovered first.
- ALWAYS handle empty results gracefully — an empty response is valid data, not an error to retry.
Counter-Rationalizations
| Shortcut |
Counter |
Why |
| "I'll skip discovery and check known resources" |
Always run Phase 1 discovery first |
Resource names change, new resources appear — assumed names cause errors |
| "The user only asked for a quick check" |
Follow the full discovery → analysis flow |
Quick checks miss critical issues; structured analysis catches silent failures |
| "Default configuration is probably fine" |
Audit configuration explicitly |
Defaults often leave logging, security, and optimization features disabled |
| "Metrics aren't needed for this" |
Always check relevant metrics when available |
API/CLI responses show current state; metrics reveal trends and intermittent issues |
| "I don't have access to that" |
Try the command and report the actual error |
Assumed permission failures prevent useful investigation; actual errors are informative |
Common Pitfalls
- Inspector v2 vs v1: This skill covers Inspector v2 (inspector2 API) -- v1 (inspector API) is legacy
- Coverage gaps: Resources without SSM agent or ECR scan config won't be scanned -- check coverage API
- Scan types: EC2 (SSM-based), ECR (image scanning), Lambda (code scanning) -- each enabled separately
- Finding status: ACTIVE, SUPPRESSED, CLOSED -- suppressed findings still exist but are filtered
- Filter criteria JSON: Must use specific JSON format for filter-criteria -- check API docs for structure
- Multi-account: Delegated admin can manage findings across organization -- check delegation status
- SBOM export: Use
create-sbom-export for software bill of materials -- async operation
- Scan frequency: ECR scans on push and periodically -- EC2 scans when new CVEs are published or packages change
