Risk scoring with exploitability context

Inspector Pricing & Free Tier

Core security services (IAM, KMS, CloudTrail, Shield Standard) are always free. Advanced features (GuardDuty, WAF, Shield Advanced) have per-usage pricing.

Inspector Best Practices

  1. 1Enable MFA on all IAM users and root account
  2. 2Never use root account for daily tasks — create IAM users with least privilege
  3. 3Enable CloudTrail across all regions with log file validation
  4. 4Rotate access keys every 90 days and never commit them to source control
  5. 5Use IAM roles for EC2/Lambda/ECS instead of long-term access keys

Getting Started with Inspector in 5 Minutes

  1. 1Open the AWS Console and navigate to Inspector
  2. 2Review the default settings — most security services are pre-configured with best-practice defaults
  3. 3Define your policies, rules, or detection scope based on your environment
  4. 4Enable logging to CloudTrail and set up alerts to SNS for critical findings
