Launch AlmaLinux 9 with STIG-aligned partitions applied at install - a layout that cannot be retrofitted after launch, avoiding costly rebuilds when auditors flag disk-layout findings. StigReady Base adds EC2 hardening (v0.1.0), SBOM and CVE metadata per build, and Nitro boot verification.
Overview
Why StigReady Base for AlmaLinux 9: STIG-required disk partition layouts must be in place at install time. Standard and many CIS-hardened AMIs lack that structure, leaving permanent findings on your PoA&M or forcing a full rebuild. StigReady Base delivers the layout and cloud baseline on official media so instances are ready for your scanning workflow.
Who this is for: Platform and DevSecOps teams building regulated workloads on AWS - use this AMI as a golden image foundation before your own profiles or a scored StigReady Applied listing.
What you get (StigReady Base tier):
- Separate mounts for /home, /tmp, /var, /var/log, /var/log/audit, /var/tmp (applied at install; not retrofittable after launch)
- EC2 cloud baseline: IMDSv2 required, no pre-installed SSH authorized_keys, PermitRootLogin and password SSH disabled, host keys regenerated on first boot
- Built from official OS install media; patched at build time
- Boot-verified on real AWS EC2 Nitro before release
- Per-version SBOM and CVE scan metadata (public catalog; see Support)
- Not a fully remediated DISA STIG or CIS score - see StigReady Applied for OpenSCAP-scored remediation
How this differs: Standard marketplace AMIs ship without STIG-aligned partitions. Post-launch STIG remediation cannot fix disk layout. StigReady Base addresses layout and EC2 hardening at the image; StigReady Applied adds scored ansible-lockdown remediation.
Getting started:
- Subscribe and launch on a Nitro instance with your SSH key.
- Connect as ec2-user; restrict security group TCP/22 to trusted IPs.
- Verify layout with lsblk; see https://stigready.com for documentation and catalog.
Marketplace OS metadata may show CentOS family for API compatibility; the image is AlmaLinux from official media.

Highlights
- Closes install-time partition gaps: STIG-aligned mounts applied at image build, not retrofittable after launch - avoids rebuilds for layout-related findings
- Per-build SBOM and CVE metadata in the public product catalog - less manual artifact gathering for assessors
- EC2 hardening from first boot: IMDSv2 required, no baked-in SSH keys; boot-verified on AWS Nitro before release

Dimensions summary
You pay by the hour based on the EC2 instance type you run this hardened AlmaLinux 9 base image on. The 17 dimensions map to specific instance sizes across four families: burstable t3 (micro through 2xlarge), general-purpose m5 and m6i (large through 4xlarge), compute-optimized c5, and memory-optimized r5. Larger sizes carry higher hourly rates, so cost scales with the compute, memory, and performance you select. This software fee is separate from the EC2 instance charges that AWS bills you directly for the underlying hardware.
Top-of-mind questions for buyers
The software fee meters running hours on the instance type you launch. A fully stopped instance does not accrue this hourly software charge. You may still owe AWS for attached storage while the instance is stopped, but that is separate from the software fee here.
You get a minimal AlmaLinux 9 image built from the official ISO, patched, and boot-tested on Nitro EC2. It includes the STIG partition layout, hardened SSH, IMDSv2 enforcement, and a pre-installed SSM Agent. You bring your own hardening profiles and tooling to apply on top.
No. The hourly rate here is a software fee only. AWS bills the underlying EC2 instance, storage, and network charges separately. Your total cost combines both: the software fee for the instance type plus the AWS infrastructure charges for running that same instance.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.

Additional details
Usage instructions
Subscribe in AWS Marketplace, then launch in EC2 with your SSH key pair. Connect via SSH as ec2-user. Open TCP port 22 only to trusted IP ranges in your security group (avoid 0.0.0.0/0 in production). This AMI requires IMDSv2-compatible instance metadata settings at launch. Documentation: https://stigready.com . Per-build SBOM and CVE scan metadata is listed in the public catalog at https://stigready.com/catalog.json (full factory evidence bundles are not web-public).
