Security Hub Insights predefined finding aggregations

Engineers running AWS Security Hub hit Security Hub Insights predefined finding aggregations often enough that there is a stable fix pattern. This page captures it in the order AWS support would run it during a real incident.

What security hub insights predefined finding aggregations actually involves on AWS Security Hub

This task on AWS Security Hub is one of the more searched operational topics on AWS in the last 12 months. The procedure below is the path that works in a current AWS account with default IAM and standard VPC config.

The rest of this page is the structured fix path. Start with diagnose, then remediation, then the automation options so you do not have to do this by hand the next time it surfaces. Verify and safety sections at the end are the discipline that keeps the fix from regressing in production.

What you'll see

Check CloudWatch Logs for the calling service. Lambda, ECS, EKS, Step Functions, API Gateway, and most managed services write detailed traces to CloudWatch Logs under predictable log group names. Use CloudWatch Logs Insights with fields @timestamp, @message | filter @message like /ERROR/ | sort @timestamp desc | limit 50 to surface the most recent failures.

Check the AWS Health Dashboard at health.aws.amazon.com for ongoing service events in your region. About one in ten user-reported outages turn out to be region-scoped AWS service degradation already being tracked. AWS Health also exposes an API and EventBridge events, so you can wire a Lambda hook that pages on-call only when the failure correlates with an active AWS Health event in the same region and service.

Reproduce the failure with the AWS CLI in --debug mode. The full SigV4 request payload it emits, plus the exact endpoint URL it resolved to, is what AWS Support uses to verify policy, region, or parameter issues without you having to share IAM credentials. Save the debug output to a file with aws ... --debug 2> debug.log and you can search it for the failed aws.request entry.

Solution-focused remediation path

If quotas are suspect, the Service Quotas console shows current usage and the active limit side by side. Request increases through Service Quotas, not through Support tickets - quota dashboard requests usually approve faster (often within minutes for soft limits) and they are auditable in CloudTrail. Set up Service Quotas + CloudWatch alarms at 80 percent usage so you get notified before you hit the wall.

When the fix involves a destructive operation (delete VPC endpoint, swap KMS key, rotate root credential), do it during a maintenance window with at least one teammate watching. Several AWS Security Hub operations have implicit dependencies that only show up when traffic starts flowing again. Document the rollback path before you start, not during the incident.

If the issue points at IAM, do not start by adding * to a policy. Use IAM Access Analyzer (Policy Generator) against the failed action to see the minimum scope. Adding * is the fastest way to fail your next AWS Well-Architected security review, and it usually does not even fix the issue because the explicit deny is often coming from a higher level (SCP, RCP, or permission boundary), not a missing allow.

Automate this fix so you do not do it twice

Codify the fix in Terraform or CloudFormation

When you reach for the console to fix the same issue twice, the third occurrence should be solved in IaC, not in the console. Terraform's terraform import and CloudFormation's resource importer let you adopt the existing resource into state without recreating it. Lock the corrected attribute behind a variable so the next operator does not have to rediscover the value. Add a moved {} block or CloudFormation resource refactor to keep the diff clean.

Automate the fix with the AWS CLI

The CLI one-liner pattern for AWS Security Hub operations is roughly: aws security describe-... --query ... to read state, aws security modify-... --no-dry-run to apply the change, and aws security describe-... --query ... again to verify. Wrap it in a shell script that sets a region variable at the top and exits on first error with set -euo pipefail so a partial run does not leave the account in a half-fixed state.

# Template - replace placeholders with your account specifics
export AWS_REGION=us-east-1
export AWS_PROFILE=prod
aws security describe-... --query 'Resources[?Status==`FAILED`].[Id,Reason]' --output table
aws security modify-... --resource-id RESOURCE_ID --no-dry-run
aws security describe-... --resource-id RESOURCE_ID --query 'Status'

Add a Systems Manager Automation runbook

For multi-step fixes that include a manual approval, use SSM Automation. Document the fix as a runbook with aws:approve steps where a human signs off and aws:executeAwsApi steps where the runbook calls the AWS API. Approvers are notified by SNS; the runbook execution shows up in CloudTrail with the approver's identity attached. This makes audit trails easy and stops production fixes from being one-person operations.

Common traps

A subtle pitfall on AWS Security Hub is that the AWS Console and the SDK can disagree about resource state during a configuration change. Console UI is cached for performance and may show the old config for up to 10 minutes after you change it via API or CloudFormation. Always confirm with describe-* CLI calls during a change window, not with screenshots from the Console.

The other pitfall: assuming that an automated remediation is correct because it succeeded. A Lambda that fires on a CloudWatch alarm and runs a remediation step should also publish a metric for every remediation; sudden surges in auto-fix invocations are themselves an outage signal. Otherwise you can hide a slow-burn regression behind a quiet remediation loop for weeks.

The repair

• Reproduce the original symptom path. If it still surfaces in any account or region or IAM role, you have not fixed it.
• Watch for 24 to 48 hours. AWS metrics and policy systems can mask issues with cached health for 6 to 12 hours, especially CloudFront and Route 53.
• Run a smoke test under realistic load. Happy-path tests miss race conditions and IAM session-cache issues.
• Capture the new state in a runbook so the next person on call does not have to rediscover this. Push it to Confluence or your team wiki, not into Slack.
• If the fix involved a permission change, run IAM Access Analyzer one more time to confirm you did not open a separate hole while closing this one.

Safety, rollback, blast radius

• Test in a non-production account if your environment has Control Tower or AWS Organizations. The cost of one sandbox account is cheaper than one rollback meeting.
• Export the existing config before changing it. Most AWS Security Hub resources support describe + export to JSON via CLI - capture that to source control before you start.
• Know your rollback path. Some AWS Security Hub operations are one-way (region migration, account-level feature opt-in, KMS key deletion past pending window). Confirm reversibility on the AWS doc before you commit.
• Be aware of cross-service impact. IAM role changes ripple to every service trusting that role. KMS key changes break every workload depending on that key. VPC endpoint changes affect every VPC consumer of that endpoint.
• Maintenance window discipline: if the change touches DNS, certificate rotation, or anything that emits TLS handshakes, line up a window with stakeholder notification, not a heroic mid-day swap.
