- Investigating security incidents or unauthorized API activity
- Meeting compliance requirements for SOC 2, HIPAA, PCI DSS, or FedRAMP
- Setting up automated alerting on sensitive AWS API calls
- Querying historical AWS activity for forensic analysis

## Create an Organization Trail

```bash
# Create the S3 bucket for log storage
aws s3api create-bucket \
  --bucket org-cloudtrail-audit-logs \
  --region us-east-1

# Apply bucket policy allowing CloudTrail to write
aws s3api put-bucket-policy \
  --bucket org-cloudtrail-audit-logs \
  --policy '{
    "Version": "2012-10-17",
    "Statement": [
      {
        "Sid": "AWSCloudTrailAclCheck",
        "Effect": "Allow",
        "Principal": {"Service": "cloudtrail.amazonaws.com"},
        "Action": "s3:GetBucketAcl",
        "Resource": "arn:aws:s3:::org-cloudtrail-audit-logs"
      },
      {
        "Sid": "AWSCloudTrailWrite",
        "Effect": "Allow",
        "Principal": {"Service": "cloudtrail.amazonaws.com"},
        "Action": "s3:PutObject",
        "Resource": "arn:aws:s3:::org-cloudtrail-audit-logs/AWSLogs/*",
        "Condition": {
          "StringEquals": {"s3:x-amz-acl": "bucket-owner-full-control"}
        }
      }
    ]
  }'

# Block public access on the audit bucket
aws s3api put-public-access-block \
  --bucket org-cloudtrail-audit-logs \
  --public-access-block-configuration \
    BlockPublicAcls=true,IgnorePublicAcls=true,BlockPublicPolicy=true,RestrictPublicBuckets=true

# Enable versioning for tamper protection
aws s3api put-bucket-versioning \
  --bucket org-cloudtrail-audit-logs \
  --versioning-configuration Status=Enabled
