How to Build an Audit-Ready CloudTrail and Config Baseline

An auditor asks: "Show who disabled logging in production last quarter." You open three accounts, find CloudTrail off in one, logs scattered in local S3 buckets, and AWS Config never enabled in the region where the incident happened.

Audit-ready logging is not "turn on CloudTrail somewhere." It is organization-wide trails, immutable central storage, Config recorders in every active region, and queries you have tested before the audit.

This article shows how to build an audit-ready CloudTrail and AWS Config baseline with AWS CLI examples and verification checks.

Who this is for: Platform and DevSecOps engineers preparing for SOC 2, ISO 27001, internal security reviews on AWS.
