AWS Amazon Inspector Tutorial: Architecture, Pricing, Use Cases, and Hands-On Guide for Security, identity, and compliance

1. Introduction

What this service is: Amazon Inspector is an AWS managed vulnerability management service that continuously scans AWS workloads for software vulnerabilities and (for some resource types) unintended exposure.
One-paragraph simple explanation: You turn on Amazon Inspector, select what you want to scan (for example, EC2 instances, container images in Amazon ECR, and AWS Lambda functions), and it automatically produces prioritized security findings with remediation guidance.
One-paragraph technical explanation: Amazon Inspector analyzes software inventory and metadata for supported resources, correlates it with vulnerability intelligence (for example CVEs), evaluates reachability context for certain findings, and publishes findings into the AWS console and APIs. Findings can be routed to tools like AWS Security Hub and Amazon EventBridge for alerting, ticketing, and automation.
What problem it solves: It reduces the operational burden of continuously identifying known vulnerabilities and risky exposure across common AWS compute packaging models (instances, containers, and serverless), and it helps teams prioritize remediation with centralized reporting.

Important naming note (legacy vs current): AWS has two related offerings: – Amazon Inspector (current service) — the modern, continuously running vulnerability management service (this tutorial). – Amazon Inspector Classic (legacy) — the earlier assessment-run model. If you see “Inspector Classic” in the console or docs, treat it as legacy and use it only if you must maintain older workflows. Prefer the current Amazon Inspector for new deployments. Verify the current lifecycle status of Inspector Classic in official AWS announcements and documentation.

2. What is Amazon Inspector?

Amazon Inspector is an AWS Security, identity, and compliance service focused on automated vulnerability management for supported AWS resources. Its official purpose is to help you discover, prioritize, and remediate software vulnerabilities and unintended exposure by continuously scanning common workload types.

Core capabilities (what it does)

Continuously scans supported compute for vulnerabilities (for example, package vulnerabilities with CVEs).
Generates security findings with severity, affected resource, and remediation recommendations.
Adds context to prioritize (for example, reachability/exposure signals for certain EC2 findings).
Integrates with AWS security and automation services to centralize and act on findings.

Major components (conceptual building blocks)

Coverage configuration: What resource types are enabled for scanning (EC2, ECR, Lambda—availability depends on region and your account setup; verify in docs).
Findings: The primary output—structured security issues that can be filtered, exported, and actioned.
Resource inventory & scanning pipeline: Service-managed collection and analysis that powers continuous evaluation.
Integrations:
AWS Organizations for multi-account enablement (delegated administrator pattern).
Amazon EventBridge for event-driven automation on findings.
AWS Security Hub for centralized security posture management (optional).

Service type

Managed AWS service (you do not manage scanners or databases yourself).
Control plane + analysis plane operated by AWS; you interact via the AWS Console, AWS CLI, and Inspector APIs (commonly referred to as the Inspector2 API in AWS SDK/CLI naming).

Scope and availability model

Regional service: Amazon Inspector is enabled and produces findings per AWS Region. Multi-region coverage requires enabling it in each region you use.
Account-scoped with multi-account support: You enable it per account, and you can centrally manage it using AWS Organizations (recommended for production).
Resource-scoped: Findings are tied to specific resources (EC2 instance IDs, ECR image digests, Lambda function versions, etc.).

How it fits into the AWS ecosystem

Amazon Inspector is typically one part of a broader AWS security stack: – AWS Security Hub aggregates findings from Inspector plus other services. – Amazon GuardDuty detects threats (behavioral/telemetry-based), while Inspector focuses on known vulnerabilities. – AWS Systems Manager is commonly used alongside Inspector for patching workflows and fleet ops. – Amazon EventBridge, SNS, and ticketing tools drive remediation automation.

3. Why use Amazon Inspector?

Business reasons

Reduce breach risk by systematically identifying exploitable known vulnerabilities.
Lower operational overhead versus building and maintaining your own scanning infrastructure.
Improve audit readiness by keeping a measurable vulnerability management process with centralized findings and history.

Technical reasons

Native AWS coverage for common workload packaging models (instances, containers in ECR, and Lambda).
Continuous scanning rather than one-time or ad-hoc checks.
API-driven workflows for integrating with CI/CD, security tooling, and ticketing systems.

Operational reasons

Centralized visibility of vulnerabilities across accounts and regions (with AWS Organizations).
Automatable response through EventBridge rules (for example: auto-create Jira tickets, open ServiceNow incidents, or notify Slack via SNS/Lambda).
Actionable remediation guidance (for example, update package versions, rebuild images, patch instances).

Security/compliance reasons

Supports vulnerability management controls that commonly appear in frameworks such as ISO 27001, SOC 2, PCI DSS, and internal security baselines (exact mapping depends on your program; verify with your compliance team).

Scalability/performance reasons

Scales with AWS-managed backend services; no scanner fleet to scale yourself.
Handles multi-account setups via delegated admin, avoiding per-account manual work.

When teams should choose it

You run workloads on EC2, ECR, and/or Lambda and need continuous vulnerability visibility.
You want AWS-native integrations and centralized governance.
You need an audit-friendly vulnerability management pipeline with evidence in AWS.

When teams should not choose it (or should supplement it)

You need deep web app scanning (DAST), SAST, or SBOM governance across non-AWS registries and build systems—Inspector is not a full AppSec platform.
Your workloads are primarily on-premises or multi-cloud and you require uniform scanning across environments (you may need a third-party platform).
You require scanning of container images stored outside Amazon ECR (Inspector’s strongest container integration is with ECR; verify current coverage in docs).

4. Where is Amazon Inspector used?

Industries

SaaS and software companies running on AWS.
Financial services and fintech (strong compliance requirements).
Healthcare and life sciences (regulated environments).
Retail/e-commerce (high availability and constant release cycles).
Media/gaming (large-scale compute fleets and containerized workloads).
Public sector (standardized security baselines and continuous monitoring).

Team types

Security engineering / vulnerability management teams.
Platform engineering and SRE teams responsible for fleet hygiene.
DevOps teams owning CI/CD and container pipelines.
Cloud Center of Excellence (CCoE) teams standardizing controls.

Workloads and architectures

Microservices on EKS/ECS using images in Amazon ECR.
EC2 fleets (ASGs, immutable infrastructure, golden AMIs).
Serverless applications (Lambda with shared layers and frequent deployments).
Multi-account landing zones with AWS Organizations.

Real-world deployment contexts

Production: Always-on scanning, findings routed to Security Hub, automated ticketing, and patch SLAs.
Dev/Test: Early detection in shared development accounts; integration with CI/CD to block promotions when high severity findings exist (often implemented via custom logic consuming Inspector findings).

5. Top Use Cases and Scenarios

Below are realistic scenarios where Amazon Inspector is commonly used.

1) Continuous EC2 vulnerability monitoring for patch SLAs

Problem: You must meet patch timelines (for example, critical CVEs within X days).
Why Inspector fits: Continuously detects vulnerable packages on supported EC2 instances and generates findings you can track over time.
Example: An operations team monitors findings and uses Systems Manager Patch Manager to patch instances weekly, verifying closure via updated findings.

2) Container image vulnerability scanning for Amazon ECR

Problem: Base images drift and new CVEs are disclosed after deployment.
Why Inspector fits: Scans images stored in ECR and produces findings tied to image digests and repositories.
Example: A platform team blocks deployment of images with critical findings by adding a pipeline gate that queries Inspector findings for the image digest.

3) Lambda package vulnerability scanning for serverless apps

Problem: Lambda dependencies include vulnerable libraries that are hard to inventory manually.
Why Inspector fits: Scans supported Lambda packages and reports vulnerable components (verify exact runtime/package coverage in docs).
Example: A serverless team gets EventBridge alerts when a new critical vulnerability affects a deployed Lambda function.

4) Multi-account vulnerability governance with AWS Organizations

Problem: Each application team runs its own AWS account; security needs central visibility.
Why Inspector fits: Supports delegated administration and organization-wide enablement.
Example: Security enables Inspector in a delegated admin account, monitors findings in aggregate, and routes them to Security Hub.

5) Prioritization using reachability context (where supported)

Problem: Too many CVEs; teams need help prioritizing what’s actually exposed.
Why Inspector fits: Can provide exposure/reachability-related context for certain findings (verify the current behavior and resource types in official docs).
Example: Focus remediation on instances reachable from the internet before internal-only systems.

6) Security Hub centralization for executive reporting

Problem: Leadership wants a single security dashboard across accounts/services.
Why Inspector fits: Findings can be sent to AWS Security Hub for aggregation with other signals.
Example: Security Hub shows Inspector critical findings trend over 90 days as a KPI.

7) Automated ticket creation and routing by ownership tags

Problem: Findings aren’t acted on because ownership is unclear.
Why Inspector fits: Findings include resource identifiers; you can map them to tags and owners via automation.
Example: An EventBridge rule triggers a Lambda that reads EC2 tags and creates a ticket in the correct team queue.

8) Immutable infrastructure validation (golden AMIs)

Problem: You bake AMIs but want to ensure they stay compliant with vulnerability thresholds.
Why Inspector fits: Continuously scans running instances derived from those AMIs; you can also scan container images in ECR used by your AMI-based services.
Example: Findings spike after a new CVE; the AMI pipeline rebuilds a patched AMI and rotates the ASG.

9) Incident response enrichment

Problem: During an incident, responders need to quickly understand if affected hosts have known vulnerabilities.
Why Inspector fits: Inspector findings provide a quick view of known vulnerabilities on affected resources.
Example: IR team correlates a GuardDuty alert with Inspector findings on the same instance to prioritize containment.

10) Compliance evidence for vulnerability management controls

Problem: Auditors request proof of ongoing vulnerability monitoring and remediation.
Why Inspector fits: Provides centralized findings, timestamps, and statuses that can support evidence collection (you still need process and documentation).
Example: Security exports findings and remediation timelines for quarterly audit packages.

11) Pre-production hardening checks

Problem: Staging environments drift and ship vulnerabilities to production.
Why Inspector fits: Continuous scanning reveals drift and missing patches early.
Example: Release managers require “no critical findings” in staging before production cutover.

12) Vulnerability trend analytics and KPI tracking

Problem: You need measurable progress and accountability.
Why Inspector fits: Findings can be aggregated and analyzed (for example via Security Hub, SIEM exports, or data lakes).
Example: A security program tracks MTTR for critical findings by application team.

6. Core Features

Feature availability can vary by region and resource type. Always confirm coverage and prerequisites in the official docs.

6.1 Continuous vulnerability scanning for supported EC2 instances

What it does: Identifies vulnerable software packages and related CVEs on supported EC2 instances.
Why it matters: EC2 fleets often contain long-lived instances where patching gaps accumulate.
Practical benefit: You get continuously updated findings instead of periodic manual scans.
Limitations/caveats:
Requires supported operating systems and collection mechanisms (often involves AWS Systems Manager/SSM availability). Verify exact OS support and requirements in docs.
Instances without proper permissions/agents may show reduced coverage.

6.2 Container image scanning for Amazon ECR

What it does: Scans images stored in Amazon Elastic Container Registry (ECR) and reports OS/package vulnerabilities.
Why it matters: Most container vulnerabilities come from base images and OS packages.
Practical benefit: You can tie findings to a repository, image tag, and digest to drive rebuild workflows.
Limitations/caveats:
Strongest integration is for images stored in ECR; external registries require alternative tooling.
Findings depend on what the service can analyze (for example, OS packages vs application dependencies—verify scope per language/runtime).

6.3 Lambda function package scanning (where available)

What it does: Scans Lambda function code packages to identify vulnerable dependencies (coverage depends on runtime and packaging; verify in docs).
Why it matters: Serverless removes server patching, but dependency vulnerabilities remain.
Practical benefit: Inventory and vulnerability visibility without adding agents.
Limitations/caveats:
Runtime and package type support varies.
Layer handling and dependency resolution details should be verified in official docs.

6.4 Network exposure / reachability findings (EC2-related)

What it does: Detects certain exposure conditions (for example, unintended network reachability) and emits findings.
Why it matters: Vulnerability risk increases when vulnerable systems are reachable from untrusted networks.
Practical benefit: Helps you prioritize remediation by exposure context.
Limitations/caveats:
The exact reachability logic and supported cases evolve; verify in docs.
It is not a full network security analysis replacement for architecture review and network firewall policy.

6.5 Findings management: filtering, severity, and remediation guidance

What it does: Provides structured findings with severity, affected resources, and recommended fixes.
Why it matters: Vulnerability data is only useful if it’s actionable.
Practical benefit: Teams can triage by severity, resource tags, repository, account, or environment.
Limitations/caveats:
“Fix available” depends on upstream packages/vendors and your patching model.

6.6 Multi-account management via AWS Organizations (delegated admin)

What it does: Centralizes enablement and visibility for an organization.
Why it matters: Most production AWS environments use multi-account strategies.
Practical benefit: Security teams can standardize coverage without logging into every account.
Limitations/caveats:
Requires AWS Organizations configuration and the right delegated admin design.
Cross-account permissions and data residency policies must be reviewed.

6.7 Integrations for alerting, automation, and aggregation

What it does:
EventBridge: route findings to automation.
Security Hub: aggregate and correlate security findings.
Why it matters: Vulnerability management requires workflow integration, not just dashboards.
Practical benefit: Create tickets, send notifications, or auto-remediate based on finding types.
Limitations/caveats:
Automation must be carefully designed to avoid unsafe auto-changes in production.

6.8 APIs, AWS CLI, and SDK support (Inspector2 API)

What it does: Enables “everything as code” enablement, reporting, and automation.
Why it matters: Production security programs need repeatable configuration and evidence.
Practical benefit: You can integrate findings into CI/CD or scheduled reporting.
Limitations/caveats:
API names in CLI/SDK often use inspector2 even though the product name is Amazon Inspector.

7. Architecture and How It Works

High-level architecture

At a high level: 1. You enable Amazon Inspector for one or more resource types in a region. 2. Inspector discovers supported resources (instances, ECR images, Lambda functions). 3. Inspector collects metadata/inventory (service-managed; EC2 often depends on SSM-managed instance connectivity and permissions—verify exact mechanisms in docs). 4. Inspector analyzes the collected data against vulnerability intelligence and exposure context. 5. Inspector publishes findings to the Inspector console/API and optionally forwards them to Security Hub and/or EventBridge.

Data/control flow (practical view)

Control plane:
Enable/disable scanning
Configure organization coverage
Configure integrations
Data plane:
Findings emitted and updated over time
Events produced for new/updated findings

Integrations with related AWS services

AWS Organizations: delegated admin, organization-wide coverage.
AWS Systems Manager (SSM): commonly required for EC2 managed instance connectivity and inventory/collection (exact prerequisites and supported OS list: verify in docs).
Amazon ECR: image storage and scanning source for container images.
AWS Lambda: functions scanned for package vulnerabilities (where supported).
Amazon EventBridge: event routing and automation.
AWS Security Hub: aggregation and security posture workflows.
Amazon CloudWatch Logs: for logs of any automation you build (Inspector itself is not a log-heavy service from your perspective; your integrations are).

Dependency services (what you often need in real deployments)

IAM: policies/roles for enabling, reading findings, and automation actions.
SSM Agent + instance profile for EC2 scanning where required.
KMS: if your integrations write to encrypted destinations (for example, encrypted SNS topics, encrypted S3 exports you create).

Security/authentication model

IAM-based access: All actions are controlled by IAM policies.
Common managed policies include Inspector read-only/full-access variants. Prefer least privilege for automation roles.

Networking model

Inspector is AWS-managed; you don’t place it in your VPC.
For EC2-related collection, your instances may need to reach SSM endpoints (public internet or VPC endpoints for Systems Manager) depending on your network design.

Monitoring/logging/governance considerations

Governance: manage enablement via AWS Organizations and infrastructure-as-code.
Monitoring: monitor automation pipelines (EventBridge → Lambda) with CloudWatch metrics/logs.
Auditability: use AWS CloudTrail to record Inspector API calls and changes to configuration (CloudTrail records API activity; verify events in your environment).

8. Prerequisites

AWS account and billing

An AWS account with billing enabled.
Permissions to create/modify:
Amazon Inspector configuration
EC2 instances and IAM roles (for the lab)
ECR repositories (optional lab part)
If using multi-account: an AWS Organizations management account and appropriate org permissions.

IAM permissions

Minimum recommended for the lab (choose one approach): – Approach A (fastest): Use an admin role for the lab, then tighten later. – Approach B (safer): Create a lab role with: – Inspector enable/list/get permissions (inspector2:* limited to needed actions) – EC2 create/terminate, IAM PassRole for EC2 instance profile – ECR create repo and push permissions (if doing ECR part) – SSM permissions for managed instances (for EC2 scanning prerequisites)

Managed policy names change over time; verify current AWS managed policies in the IAM console or official docs.

Tools

AWS CLI v2 (recommended)
Install: https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html
Docker (only if you do the ECR image push steps)
Optional: jq for JSON filtering in CLI outputs

Region availability

Amazon Inspector is regional. Choose a region where Inspector is available.
Some capabilities (especially Lambda scanning) may be region-dependent—verify in official docs for your region.

Quotas/limits

Service quotas apply (for example, finding/event throughput, resource coverage). Check:
AWS Service Quotas console
Inspector documentation for any listed limits
If uncertain, verify in official docs.

Prerequisite services (for EC2 scanning)

AWS Systems Manager (SSM) connectivity is commonly required for EC2 vulnerability scanning on supported OSes:
SSM Agent installed/running
Instance profile with AmazonSSMManagedInstanceCore
Network path to SSM endpoints (public internet or VPC endpoints)

9. Pricing / Cost

Official pricing page (start here): https://aws.amazon.com/inspector/pricing/
AWS Pricing Calculator: https://calculator.aws/#/

Pricing changes over time and varies by region and usage patterns. Use the official pricing page and the AWS Pricing Calculator for current rates.

Pricing dimensions (how you are billed)

Amazon Inspector pricing is typically based on what you scan and how much of it you scan, such as: – EC2 instance scanning: commonly driven by the number of instances, their size (for example vCPU count), and time scanned. (Verify the exact unit—such as vCPU-hours—in the pricing page for your region.) – ECR image scanning: commonly driven by the number of container images scanned (and potentially re-scanned as new CVEs are published). – Lambda scanning: commonly driven by the number of functions and/or amount of code scanned (verify the exact billing unit in the pricing page).

Free tier / trial

AWS sometimes offers a free trial for Amazon Inspector for first-time enablement. Availability and duration can change. Verify in the official pricing page for your account/region.

Main cost drivers

Scale of compute:
Many EC2 instances (especially larger instances) increase scanning cost.
High churn of ECR images (frequent builds) increases scanning cost.
Large numbers of Lambda functions or frequent deployments may increase scanning volume.
Multi-account + multi-region: Enabling in many accounts/regions multiplies coverage and cost.

Hidden or indirect costs

Inspector itself is managed, but your overall solution may include: – EventBridge + Lambda automation costs (invocations, logs). – Security Hub charges (if you enable it and ingest findings). – Data storage costs if you export findings to S3 or a data lake. – Operational cost of remediation (patching windows, rebuild pipelines).

Network/data transfer implications

Inspector is an AWS managed service; you generally don’t pay special data transfer to “send data to Inspector”.
If your automation exports findings cross-region or to the internet (for example to external SIEM), data transfer charges may apply.

How to optimize cost (practical guidance)

Scan only what you need: enable only the resource types you use.
Reduce ECR image churn: clean up unused tags/images; keep a retention policy.
Use immutable pipelines: rebuild patched images rather than patching containers in place.
Prioritize critical workloads first in large environments (phased rollout).
Use centralized governance: avoid redundant overlapping tooling unless necessary.

Example low-cost starter estimate (how to think about it)

A small dev account might include: – 1–2 small EC2 instances – A handful of ECR images – Few Lambda functions

Estimate by plugging your instance sizes, hours, and image build volume into the AWS Pricing Calculator and comparing regions. Do not rely on fixed numbers from blogs—rates vary.

Example production cost considerations

In production, costs often correlate with: – Hundreds/thousands of EC2 instances across multiple regions – CI/CD pipelines producing many images per day – Organization-wide enablement across many accounts

For enterprise forecasting: – Start with an inventory (instances by vCPU, image build count, function count). – Run a pilot in one region for 2–4 weeks, then extrapolate. – Validate assumptions against the pricing page for your region.

10. Step-by-Step Hands-On Tutorial

Objective

Enable Amazon Inspector in a single AWS account and region, scan: 1) one EC2 instance for vulnerabilities, and
2) one container image pushed to Amazon ECR,
then view findings and clean up resources to minimize cost.

Lab Overview

You will: 1. Create an EC2 instance that is managed by AWS Systems Manager (SSM). 2. Enable Amazon Inspector scanning. 3. Create an ECR repository and push a test image. 4. Review Inspector findings in the console and via AWS CLI. 5. Clean up EC2/ECR and optionally disable Inspector.

Expected time: 45–90 minutes (depends on image push and scan time)
Cost: Low, but not zero. Use small instances and delete resources afterward. Inspector charges depend on usage—see pricing page.

Step 1: Choose a region and set up AWS CLI

Pick a region you will use for the entire lab (example: us-east-1). Make sure Amazon Inspector is available in that region.
Configure AWS CLI credentials:

aws configure
# Provide AWS Access Key ID, Secret Access Key, default region, and output format

Expected outcome: AWS CLI can call AWS APIs in your chosen region.

Verify:

aws sts get-caller-identity
aws configure get region

Step 2: Create IAM role for EC2 with SSM managed instance permissions

Amazon Inspector’s EC2 vulnerability scanning commonly relies on EC2 being a managed instance in AWS Systems Manager (verify exact prerequisites for your OS in official docs).

Create an IAM role for EC2 with the managed policy AmazonSSMManagedInstanceCore.

Console path: IAM → Roles → Create role → AWS service → EC2 → Attach permissions → search and attach: – AmazonSSMManagedInstanceCore

Name it: LabEC2SSMRole

Create an instance profile automatically (the console will do this when you create the role).

Expected outcome: You have an EC2 role you can attach to an instance so it registers in SSM.

Verify (CLI):

aws iam get-role --role-name LabEC2SSMRole

Step 3: Launch a small EC2 instance (SSM-managed)

Launch an EC2 instance: – AMI: Amazon Linux 2023 or Amazon Linux 2 (choose one supported by your org; OS support can affect findings). – Instance type: small (for example t3.micro if eligible). – IAM instance profile: LabEC2SSMRole – Network: default VPC is fine for a lab – Security group: allow no inbound access (recommended). You do not need SSH for this lab. – Tags: Name=inspector-lab-ec2, Env=lab
Wait until the instance state is running.

Expected outcome: Instance is running with SSM permissions.

Verify that the instance is managed by SSM: – Console: Systems Manager → Fleet Manager → Managed nodes (or “Managed instances” depending on console experience) – CLI:

aws ssm describe-instance-information \
  --query "InstanceInformationList[].{InstanceId:InstanceId,PingStatus:PingStatus,PlatformName:PlatformName,AgentVersion:AgentVersion}" \
  --output table

If the instance does not appear: – Confirm SSM Agent is installed/running (Amazon Linux typically includes it). – Confirm the instance has outbound network access to SSM endpoints (NAT/IGW or VPC endpoints). – Confirm the instance profile includes AmazonSSMManagedInstanceCore.

Step 4: Enable Amazon Inspector

You can enable via the console or CLI. The CLI typically uses the inspector2 namespace.

Option A: Enable via Console (recommended for beginners)

Open Amazon Inspector console in your chosen region.
Choose Get started / Enable (wording may vary).
Select resource types to scan: – EC2 – ECR – (Optional) Lambda if available/needed
Confirm enablement.

Expected outcome: Amazon Inspector starts evaluating supported resources in that region.

Option B: Enable via AWS CLI

CLI arguments can evolve. If a command fails, verify the current CLI syntax in the official AWS CLI reference for inspector2.

Try:

aws inspector2 enable --resource-types EC2 ECR

Expected outcome: The service is enabled for the specified resource types.

Verify (one way is to check coverage statistics or list configured resources; exact commands may vary by version—verify in docs/CLI help):

aws inspector2 list-account-permissions --max-results 10 2>/dev/null || true
aws inspector2 get-configuration 2>/dev/null || true
aws inspector2 list-coverage --max-results 10 2>/dev/null || true

If these commands are not recognized or return errors, use:

aws inspector2 help

…and consult the current CLI reference.

Step 5: Wait for EC2 findings and review them

Amazon Inspector findings may take time to appear after enabling.

In the Inspector console: – Go to Findings – Filter by:
- Resource type: EC2 instance
- Resource ID: your instance ID
In CLI (example approach): – First list findings (can be large; consider filtering):

aws inspector2 list-findings --max-results 25

To filter for EC2 findings only (filter syntax can be specific—verify filter keys in current docs):

aws inspector2 list-findings \
  --filter-criteria '{"resourceType":[{"comparison":"EQUALS","value":"AWS_EC2_INSTANCE"}]}' \
  --max-results 25

Expected outcome: You see one or more findings (if the instance has vulnerable packages or exposure conditions detectable by Inspector).

If you see no findings: – The instance might be fully patched. – Wait longer (initial scans can take time). – Try installing a package and delaying patching (safe, non-production). For example, install common packages and then run updates later. Findings depend on actual package versions and vulnerability intelligence.

Step 6: Create an ECR repository and push a test image

This step helps demonstrate container image findings. You need Docker installed locally.

Create an ECR repository:

aws ecr create-repository --repository-name inspector-lab-repo

Capture the repository URI:

REPO_URI=$(aws ecr describe-repositories \
  --repository-names inspector-lab-repo \
  --query "repositories[0].repositoryUri" \
  --output text)

echo "$REPO_URI"

Authenticate Docker to ECR:

aws ecr get-login-password | docker login --username AWS --password-stdin "$REPO_URI"

Create a simple Dockerfile that intentionally uses an older base OS (often yields findings). Results vary—this is a demonstration.

Create Dockerfile:

FROM debian:9
RUN apt-get update && apt-get install -y curl ca-certificates && rm -rf /var/lib/apt/lists/*
CMD ["bash","-lc","curl --version && sleep 3600"]

Build and tag the image:

docker build -t inspector-lab:1 .
docker tag inspector-lab:1 "$REPO_URI:1"

Push the image:

docker push "$REPO_URI:1"

Expected outcome: Image is stored in ECR.

Verify:

aws ecr describe-images --repository-name inspector-lab-repo --output table

Step 7: Wait for ECR image findings and review them

Inspector console: – Findings → filter resource type = ECR image – Filter by repository name inspector-lab-repo
CLI (example): – List findings and filter by resource type for container images (filter keys can vary; verify in docs):

aws inspector2 list-findings \
  --filter-criteria '{"resourceType":[{"comparison":"EQUALS","value":"AWS_ECR_CONTAINER_IMAGE"}]}' \
  --max-results 25

Expected outcome: Findings associated with the pushed image digest may appear (timing varies).

Step 8 (Optional): Send findings to EventBridge for automation

Inspector findings can be routed through EventBridge. A simple lab-friendly automation is “log the event” (for example, to CloudWatch Logs via a Lambda). This optional step focuses on the EventBridge rule.

Open Amazon EventBridge console → Rules → Create rule.
Event source: AWS events (EventBridge pattern)
Pattern: choose service/provider corresponding to Inspector findings (wording varies).
Target: choose an SNS topic or Lambda function you control.

Because event schema and fields can change, verify the exact EventBridge event pattern for Amazon Inspector in official docs before relying on it in production.

Expected outcome: When new findings appear or change, your target receives events.

Validation

Use this checklist:

Inspector enabled in your region: – Console shows “Enabled”
EC2 instance is SSM-managed: – aws ssm describe-instance-information shows your instance
Findings visible: – Inspector console shows findings for EC2 and/or ECR
ECR image exists: – aws ecr describe-images returns image tags/digests

If you want to validate remediation mechanics (optional): – Patch the EC2 instance (for example via SSM Run Command) and observe that findings reduce over time. – Rebuild the container image using a newer base image and push a new tag/digest, then compare findings.

Troubleshooting

Issue: EC2 instance not showing in SSM

Confirm instance profile has AmazonSSMManagedInstanceCore.
Confirm outbound connectivity to SSM endpoints:
If in private subnets, configure VPC endpoints for Systems Manager (SSM, EC2Messages, SSMMessages) or provide NAT.
Confirm SSM Agent is installed and running.

Issue: Inspector enabled but no EC2 findings

Wait longer—initial evaluations can take time.
Ensure the OS is supported for vulnerability scanning (verify in docs).
Ensure SSM managed node status is “Online”.
If the instance is fully patched, there may be few/no findings.

Issue: Docker push fails to ECR authentication

Re-run the get-login-password command.
Ensure your IAM principal has ECR permissions (ecr:GetAuthorizationToken, ecr:PutImage, ecr:InitiateLayerUpload, etc.).
Ensure the repository URI is correct for your account/region.

Issue: No ECR findings

Wait longer after push; scans are not always instantaneous.
Confirm Inspector is enabled for ECR in the region.
Confirm you pushed to ECR in the same region where Inspector is enabled.

Cleanup

To minimize cost, clean up immediately after the lab.

Terminate the EC2 instance:

# Find instance ID by tag (adjust region/profile if needed)
INSTANCE_ID=$(aws ec2 describe-instances \
  --filters "Name=tag:Name,Values=inspector-lab-ec2" "Name=instance-state-name,Values=running,stopped" \
  --query "Reservations[].Instances[].InstanceId" \
  --output text)

echo "$INSTANCE_ID"

aws ec2 terminate-instances --instance-ids "$INSTANCE_ID"

Delete ECR images and repository:

# List image digests
aws ecr list-images --repository-name inspector-lab-repo --query 'imageIds[*]' --output json

# Batch delete images (safe for lab repo)
aws ecr batch-delete-image --repository-name inspector-lab-repo --image-ids imageTag=1

# Delete repository
aws ecr delete-repository --repository-name inspector-lab-repo

(Optional) Disable Inspector if you don’t want ongoing charges: – Console: Amazon Inspector → Settings → Disable (wording varies) – CLI (verify current syntax):

aws inspector2 disable --resource-types EC2 ECR

Delete IAM role LabEC2SSMRole if created only for this lab.

11. Best Practices

Architecture best practices

Enable organization-wide using AWS Organizations (delegated admin) for consistent coverage.
Adopt a standard severity policy: define what “Critical/High” means operationally (SLA, escalation, exceptions).
Use immutable deployments:
For containers: rebuild images from patched bases and redeploy.
For EC2: prefer replacing instances via ASG/launch templates after patching AMIs.

IAM/security best practices

Least privilege for:
Roles that read findings
Automation that remediates
Separate roles:
Viewer role (read-only)
Automation role (limited actions like creating tickets, patching, updating security groups)
Restrict sensitive actions with conditions (for example, tag-based conditions) where feasible.

Cost best practices

Phase enablement: start with production accounts and internet-facing workloads.
Reduce ECR bloat: implement lifecycle policies to delete unneeded images.
Right-size EC2: cost scales with fleet size; right-sizing helps security and cost.

Performance best practices (operational responsiveness)

Use EventBridge to avoid polling the API.
Optimize automation to handle bursty findings (batch, backoff, idempotency).

Reliability best practices

Treat remediation automation as production software:
retries
dead-letter queues (DLQs) where applicable
alarms on failures

Operations best practices

Tagging: enforce tags like App, Owner, Env, CostCenter.
Triage workflow: 1. Confirm exploitability/exposure (context) 2. Patch or rebuild 3. Verify closure 4. Track exceptions with expiration dates
Change management: schedule patch windows; coordinate with release cycles.

Governance/tagging/naming best practices

Standardize:
ECR repository naming (team/app/env)
EC2 instance tags and ASG naming
Lambda function naming
Use AWS Organizations SCPs (carefully) to enforce minimum security baselines if needed.

12. Security Considerations

Identity and access model

All access is controlled by IAM.
Use:
IAM roles for humans (SSO/federation)
IAM roles for automation (EventBridge/Lambda)
Monitor with CloudTrail for enable/disable actions and configuration changes.

Encryption

Findings are stored and managed by AWS; for exports/integrations you build:
Use SSE-KMS for S3 exports
Encrypt SNS topics and queues with KMS
Verify encryption defaults and options in Inspector docs and related service docs.

Network exposure

Inspector itself is AWS-managed.
For EC2 scanning prerequisites (SSM connectivity), ensure:
Instances can reach SSM endpoints securely (prefer VPC endpoints in private subnets).
Restrict outbound egress where possible with proxy/NACL/security group policy.

Secrets handling

Avoid embedding credentials in remediation scripts.
Use AWS Secrets Manager or SSM Parameter Store for external ticketing tokens and API keys.
Rotate credentials and restrict access.

Audit/logging

CloudTrail: records Inspector API usage.
Security Hub (optional): central audit trail of findings across services.
Automation logs: CloudWatch Logs for Lambdas and pipelines.

Compliance considerations

Inspector supports vulnerability management, but compliance requires:
documented process
remediation SLAs
exception process
evidence retention
Validate against your framework requirements (PCI, HIPAA, SOC2, etc.).

Common security mistakes

Enabling Inspector but not assigning ownership → findings pile up.
Over-permissive automation that patches production without guardrails.
Ignoring image rebuild discipline (containers) and repeatedly patching running workloads.
Missing multi-region enablement in global architectures.

Secure deployment recommendations

Centralize in a security account using AWS Organizations.
Route findings to Security Hub and/or a SIEM for retention and correlation.
Implement automated triage, but keep remediation gated (approvals for production).

13. Limitations and Gotchas

Regional enablement: If you forget to enable Inspector in a region where you run workloads, you’ll have blind spots.
Resource coverage depends on prerequisites:
EC2 scanning often depends on supported OS and SSM-managed connectivity—verify the support matrix.
Container scope: Inspector’s container scanning is primarily aligned to Amazon ECR usage; if your images live elsewhere, plan for additional tooling.
Finding volume: Large fleets produce lots of findings. Without filtering, routing, and ownership, teams get alert fatigue.
Timing: Initial scans and finding updates are not always immediate; plan for delays.
Multi-account complexity: Delegated admin setup is straightforward, but consistent tagging/ownership across accounts is not—plan governance early.
Cost surprises:
High image build churn in CI/CD can increase scanning volume.
Enabling across many accounts/regions multiplies usage.
Remediation verification: A patched system may take time to reflect updated findings; don’t assume instant closure.
Legacy confusion: “Inspector Classic” workflows are different; don’t mix run-based classic assessments with the continuous model.

14. Comparison with Alternatives

Amazon Inspector is best understood as AWS-native vulnerability management for certain AWS resource types. It complements (not replaces) threat detection, posture management, and AppSec testing.

Comparison table

Option	Best For	Strengths	Weaknesses	When to Choose
Amazon Inspector	Continuous vulnerability scanning of EC2/ECR/Lambda in AWS	Managed, integrates with AWS Organizations, Security Hub, EventBridge; continuous findings	Not a full SAST/DAST platform; scope depends on supported resources; region-by-region enablement	You want AWS-native vulnerability management for core AWS workloads
AWS Security Hub	Central aggregation and posture dashboards	Aggregates findings from many AWS services; compliance checks	Not a scanner by itself; relies on producers like Inspector	You need a single pane of glass and standardized workflows
Amazon GuardDuty	Threat detection based on logs/telemetry	Detects malicious activity patterns; strong signal for active threats	Not focused on known CVEs/package vulnerabilities	You need threat detection and continuous monitoring
AWS Systems Manager Patch Manager	Patch orchestration for EC2	Automates patching workflows and maintenance windows	Doesn’t inherently discover all vulnerability context; patching ≠ vulnerability prioritization	You need to execute patching at scale (often used with Inspector)
ECR basic scanning (if enabled separately)	Lightweight image scanning	Simple, integrated	May be less comprehensive than Inspector-based scanning; verify current capabilities	Very small environments or early-stage scanning needs
Microsoft Defender for Cloud (other cloud)	Multi-cloud security posture + some vuln capabilities	Broad coverage across clouds	Integration and depth vary; may not map perfectly to AWS resources	You’re standardizing multi-cloud security tooling
Google Security Command Center / container scanning (other cloud)	GCP-centric security	Strong GCP integration	Not AWS-native	Workloads are primarily on GCP
Self-managed OpenVAS/Trivy/Clair (open-source)	Custom scanning pipelines	Flexible; can run anywhere	You manage infrastructure, updates, scaling, false positives	You need portability, custom rules, or non-AWS registry coverage

15. Real-World Example

Enterprise example (multi-account, regulated)

Problem: A regulated enterprise runs 200+ AWS accounts. Auditors require continuous vulnerability management with evidence of remediation SLAs.
Proposed architecture:
AWS Organizations with a dedicated Security tooling account
Amazon Inspector enabled org-wide (delegated admin)
Findings forwarded to AWS Security Hub
EventBridge rules route critical findings to:
- ticketing integration (Lambda)
- notification channels (SNS)
Patch and rebuild:
- EC2 patched via Systems Manager maintenance windows
- Containers rebuilt via CI/CD with updated base images
Why Inspector was chosen:
AWS-native continuous scanning and org-level governance
Tight integration with Security Hub and AWS automation
Expected outcomes:
Reduced mean time to detect (MTTD) vulnerabilities
Standardized reporting for audits
Clear ownership routing and SLA tracking

Startup/small-team example (single account, container-first)

Problem: A small team ships weekly. They use ECS with images in ECR and want vulnerability visibility without running scanners.
Proposed architecture:
Enable Amazon Inspector for ECR in one region
EventBridge → Slack notifications (via Lambda) for critical findings in production repositories
CI/CD gate: block deployment if the target image digest has critical findings (custom script querying Inspector API)
Why Inspector was chosen:
Minimal operational overhead
Native to ECR, fits existing AWS workflow
Expected outcomes:
Faster feedback loop on base image issues
Fewer vulnerable images promoted to production
Lightweight governance without extra infrastructure

16. FAQ

Is Amazon Inspector the same as Amazon Inspector Classic?
No. Amazon Inspector (current) is designed for continuous vulnerability scanning of supported AWS resources. Inspector Classic is the older run-based assessment product. Prefer the current Amazon Inspector for new deployments.
Is Amazon Inspector global or regional?
It is regional. Enable and manage it per AWS Region, and plan for multi-region enablement if your workloads span regions.
What resource types can Amazon Inspector scan?
Commonly: EC2 instances, ECR container images, and Lambda functions. Exact coverage and prerequisites vary—verify in official docs for your region.
Does Inspector require an agent on EC2?
The current Inspector commonly relies on AWS-managed mechanisms and often works with SSM-managed instances rather than a dedicated legacy agent. Confirm the latest requirements and supported OS list in official docs.
How long does it take for findings to appear after enabling?
It varies. Initial discovery and scanning can take minutes to hours depending on resource type and environment conditions.
Can I enable Inspector across all accounts at once?
Yes, using AWS Organizations with a delegated administrator model (recommended for production).
How do I route findings to my SIEM?
Typical pattern: Inspector → Security Hub (optional) and/or Inspector → EventBridge → Lambda/Kinesis/partner integration → SIEM. Exact implementation depends on your SIEM.
Does Inspector block deployments automatically?
Not by default. You implement deployment gates in CI/CD by querying Inspector findings (or consuming them via Security Hub) and enforcing your policy.
Does Inspector scan images in Docker Hub or other registries?
Inspector’s strongest container integration is with Amazon ECR. For other registries, use additional tooling or mirror images into ECR (validate policy and licensing).
How should I prioritize vulnerabilities from Inspector?
Use severity, exploitability context (where provided), resource exposure, asset criticality, and environment (prod vs dev). Tie this to SLAs and ownership.
Can Inspector generate false positives?
Any vulnerability tool can. Validate critical findings and maintain an exception workflow with expiration and review.
What’s the difference between Inspector and GuardDuty?
Inspector focuses on known vulnerabilities and exposure. GuardDuty focuses on threat detection using logs/telemetry and anomaly detection.
Do I need Security Hub to use Inspector?
No. Inspector can be used standalone, but Security Hub is helpful for aggregation and workflows.
How do I reduce Inspector costs?
Limit scanning to needed resource types/regions, reduce ECR image churn, clean up unused images, and roll out in phases.
How do I prove remediation to auditors?
Combine Inspector findings history (timestamps/status), ticketing evidence, patch logs (SSM), and change management records. Inspector is one input to the evidence package.

23. Summary

Amazon Inspector is an AWS Security, identity, and compliance service for continuous vulnerability management across supported AWS workload types (commonly EC2, ECR, and Lambda). It matters because vulnerability discovery and prioritization are ongoing problems—new CVEs appear constantly, and fleets drift over time.

Architecturally, Inspector fits best when you: – run AWS-native workloads, – want centralized findings (often via AWS Organizations and Security Hub), – and want automation through EventBridge.

From a cost perspective, the main drivers are the amount of compute and artifacts you scan (instances by size/time, number of images, and function scan volume). Avoid surprises by scoping enablement, managing ECR lifecycle, and piloting in one region before scaling.

If your goal is practical next steps: enable Inspector in one region, validate EC2 and ECR coverage, route critical findings to a ticketing workflow, and then expand organization-wide with delegated admin once your remediation process is ready.
