Hardened Rocky Linux 10 (ARM)

This is a repackaged open source software product wherein additional charges apply for Hardened Images security hardening, ongoing image maintenance, release evidence, and Hardened Images support.

Hardened Rocky Linux 10 (ARM) gives teams a production-ready ARM64 operating system baseline for Hardened-scoped workloads on AWS.

Move from a general-purpose Rocky image to a documented, security-focused starting point without spending weeks designing controls, building hardening automation, troubleshooting configuration dependencies, and assembling release evidence. Hardened Images handles the operating system baseline so your team can focus on your applications and the controls specific to your environment.

What You Get

• Hardened Images-applied Rocky 10 security hardening designed to support Hardened infrastructure requirements
• Security-focused configuration across authentication, account policy, privilege boundaries, audit logging, networking, services, kernel settings, file permissions, and other operating system safeguards
• Current Rocky package and security updates applied during the controlled image build
• Pre-hardening and post-hardening assessment results, remediation history, and a release-specific evidence report for the exact image release
• A clean, application-neutral AMI with no bundled business applications, security agents, or platform lock-in
• Ongoing Hardened Images image maintenance and direct access to a Hardened Images support team

Built for Security-Focused and Regulated Workloads

Use this image as a repeatable baseline for:

• Security-focused production workloads
• Regulated development and test environments
• Audit remediation projects
• Golden image programs
• Organizations that need a faster path to a defensible Linux baseline

The AMI helps reduce manual hardening effort and configuration drift across AWS accounts and environments. Infrastructure teams can deploy the same reviewed baseline behind their own network controls, identity model, deployment pipeline, observability stack, backup policy, and workload configuration.

Security and compliance teams also gain release records that are easier to trace directly to the image being deployed.

This image is built for ARM64 EC2 instances and supports AWS Graviton instance families and ARM64-native application stacks.

Deploy and Operate with Confidence

The image is ready for use when launched. Hardened Images recommends AWS Systems Manager Session Manager (SSM) for administrative access whenever possible so SSH does not need to be exposed to the public Internet.

If SSH is required, use the rocky account, your selected EC2 key pair, and tightly scoped network access.

Detailed usage instructions in this listing cover connection methods, accessing hardening evidence, and getting support.

For routine updates, apply Rocky security patches through your approved change process. When Hardened Images publishes a new image version, validate it outside production before using a controlled replacement or migration process.

Hardening Evidence

Each Hardened Images release includes supporting documentation and release-specific hardening evidence. Use the Hardened Images documentation and Trust Center resources referenced in this listing to review:

• Applied security controls
• Pre-hardening and post-hardening assessment results
• Remediation history
• Release-specific validation evidence
• Documented exceptions, where applicable

Hardened Images Support Included

Email support@hardenedimages.com  for help with:

• Choosing the right image
• Understanding hardening behavior
• Patching or upgrade planning
• Locating release evidence
• Troubleshooting image behavior
• Hardened review questions related to the operating system baseline

Support requests are handled by Hardened Images's Hardened Images team.

Scope and Customer Responsibility

This AMI is designed to support Hardened infrastructure objectives, but launching a hardened image does not by itself make an application, AWS account, regulated environment, or organization secure or compliant with any external framework.

Customers remain responsible for the security and compliance of their complete environment, including application security, IAM, network segmentation, encryption, key and secret management, logging, monitoring, vulnerability management, backups, incident response, operational procedures, and compliance validation.

Review the provided evidence against your organization's requirements and involve your assessor where appropriate.
