This AMI delivers CentOS Stream 10 hardened following Red Hat STIG guidance and tuned for EC2 by Easycloud-with before/after security scan reports and SBOM.
Overview
This is a repackaged open source software product wherein additional charges apply for a pre-hardened, AWS-optimized image with verifiable compliance evidence and maintenance. Based on CentOS Stream 10, this AMI is hardened following Red Hat STIG guidelines, tuned for Amazon EC2 workloads, and equipped with a complete OpenSCAP evidence pack and Software Bill of Materials (SBOM).
Value-Added Features
Security & Compliance:
-
Red Hat STIG Alignment: 356 security controls applied via the SCAP Security Guide, including auditd logging, SSH hardening, kernel command line and module blocklist restrictions, and strict password policy enforcement.
-
Fully Patched at Release: Zero packages with a pending update at build time, verified. The complete CVE scan ships inside the image.
-
Comprehensive Evidence Pack: Every AMI includes an OpenSCAP evidence pack generated against Red Hat STIG guidance for CentOS Stream 10, located under /opt/hardening-report/:
- Base_Report.html: Pre-hardening OpenSCAP scan report representing the initial baseline.
- Tailored_Profile_Report.html: Post-hardening scan report evaluated against the tailored profile shipped inside this image.
- Raw_STIG_Report.html: Post-hardening scan report evaluated against the unmodified baseline Red Hat STIG profile.
- Exceptions.txt: Itemized list of unapplied STIG rules along with technical justifications (AWS compatibility, site-specific policies, CSP service conflicts).
- Tuning_Parameters.txt: Every performance tuning parameter applied on top of the hardening, each shown against its base-image value.
- compliance_mapping.csv: Rule-by-rule mapping to NIST SP 800-53 controls and Red Hat STIG identifiers with pass/fail statuses.
- package_changes.txt: Package delta report comparing the final image against the minimal stock installation.
- sbom.spdx.json: Software Bill of Materials (SBOM) in SPDX format generated from the RPM database.
- cve_scan.txt / cve_scan_full.txt.gz: Vulnerability scan reports categorizing CVEs by upstream patch availability.
- key_files.sha256: SHA-256 checksums of the key configuration files changed by the hardening, so the delivered state can be verified.
- README.txt: Index file detailing artifact contents, administrative operational guidelines, and configuration defaults.
System Footprint & Reliability Optimization:
-
Minimal Footprint: Built on a minimal OS installation to reduce the attack surface and remove unnecessary packages.
-
Storage Layout: Configured with a streamlined 10 GB root (/) partition layout to minimize disk footprint while ensuring core system operation.
-
Validation Testing: Functional verification conducted on clean AMI launches through multi-round integration testing, verifying complete software lifecycle operations with SELinux enforcing.
AWS Network & Kernel Tuning:
-
Network Stack: TCP BBR congestion control with fair queueing, increased connection backlogs, buffer adjustments, and MTU probing enabled.
-
System Tuning: Red Hat tuned daemon active with a custom cloud profile, custom transparent hugepages (madvise), and modified memory/EBS writeback parameters.
-
EC2 Integration: Configured with NVMe I/O timeouts, Amazon Time Sync (chrony), IRQ balance daemon, and size-capped persistent journald logging.
Operational Tools
- Preinstalled Tools: AWS SSM Session Manager enabled, CloudWatch Agent installed (disabled by default).
Maintenance:
- Maintenance Specifications: Rebuilt and updated bi-weekly to monthly incorporating upstream CentOS Stream 10 security updates, updated artifact documentation per release, and administrative documentation.
About CentOS Stream 10
-
CentOS Stream 10 Foundation: Provides a robust, enterprise-grade underlying OS with deep structural alignment to RHEL, ensuring high security and seamless ecosystem compatibility with AlmaLinux, Rocky Linux, and traditional CentOS deployments.
-
Next-Generation RHEL Platform: CentOS Stream 10 tracks the leading edge of the RHEL 10 development branch, giving teams early access to the same packages that will ship in future RHEL 10 point releases. This provides a predictable upgrade path and broad compatibility with the Red Hat software ecosystem across development, staging, and production workloads.
Highlights
- Red Hat STIG Hardened Base: Pre-configured with 356 security controls applied via the SCAP Security Guide, incorporating SSH hardening, kernel command line and module blocklists, and strict password policies out of the box.
- Comprehensive Compliance Reports & SBOM: Includes verifiable security audit reports and a complete Software Bill of Materials (SBOM), enabling instant verification of Red Hat STIG posture and rapid vulnerability assessments out-of-the-box.
- AWS Performance Tuning & Regular Updates: Optimised for EC2 with TCP BBR and Red Hat tuned cloud profiles, updated bi-weekly to monthly with upstream security patches.

Dimensions summary
You pay by the hour for this hardened CentOS Stream 10 image, billed only while an instance runs. Each dimension maps to a specific AWS EC2 instance type, so your price follows the compute size you choose. Options span small burstable types through large memory-, compute-, storage-, and GPU-focused families, up to bare metal. Larger instance types carry higher hourly rates because they provide more CPU, memory, or specialized resources. Pick the instance type that matches your workload; the software rate is added to the underlying AWS infrastructure charge. No upfront commitment applies.
Top-of-mind questions for buyers
One unit is one running EC2 instance of the type you select. Billing counts each hour that instance runs. The software rate is tied to the instance family and size. It applies on top of the AWS infrastructure charge for that same instance.
The software rate meters running time only. A fully stopped instance does not accrue software charges. You may still pay AWS for attached storage while the instance is stopped, but that is separate from the hourly software fee shown here.
The image applies security hardening to reduce the attack surface, following recognized security benchmarks. The vendor also offers configuration, firewall, and access-control work as part of its hardening approach. Check the listing details to confirm exactly which controls ship pre-configured in this specific image.
