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. PostgreSQL 18 runs on a Rocky Linux 9.8 base hardened following DISA STIG guidelines, tuned for Amazon EC2 workloads, and shipped with a complete OpenSCAP evidence pack and Software Bill of Materials (SBOM).
Value-Added Features
PostgreSQL 18 Deployment:
-
Best-Practice Deployment: PostgreSQL 18 professionally packaged by experienced engineers for a stable, optimized environment on a minimal OS installation.
-
Bloat-Free Data Layer: CPU and memory go to query planning and transaction processing rather than unused system services.
-
Broad Ecosystem Fit: Serves relational and analytical workloads and ORM-driven application layers built with Hibernate and SQLAlchemy, alongside modern frameworks such as Django, Ruby on Rails, and FastAPI.
Hardened Operating System Base:
-
DISA STIG Alignment: 339 security controls applied to the Rocky Linux 9.8 base 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.
-
Documented Exceptions: Every STIG rule not applied is itemized with a technical justification, so the delivered posture is auditable.
Comprehensive Evidence Pack:
Every AMI carries an OpenSCAP evidence pack generated against DISA STIG guidance, under /opt/hardening-report/:
- Base_Report.html: Pre-hardening scan report, the initial baseline.
- Tailored_Profile_Report.html: Post-hardening report against the tailored profile shipped in this image.
- Raw_STIG_Report.html: Post-hardening report against the unmodified baseline DISA STIG profile.
- Exceptions.txt: Itemized unapplied STIG rules with technical justifications (AWS compatibility, site-specific policies, CSP service conflicts).
- Tuning_Parameters.txt: Every 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 DISA STIG identifiers with pass/fail statuses.
- package_changes.txt: Package delta against the minimal stock installation.
- sbom.spdx.json: Software Bill of Materials 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 of artifact contents, operational guidelines, and configuration defaults.
Reliability Validation:
- Validation Testing: Functional verification on clean AMI launches through multi-round integration testing, covering the complete database lifecycle 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, transparent hugepages set to madvise, and modified memory/EBS writeback parameters.
-
EC2 Integration: 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 PostgreSQL and Rocky Linux 9.8 security updates, with artifact documentation refreshed per release.
About PostgreSQL 18
One of the world's most advanced open-source relational database systems, known for strict ACID compliance, a rich SQL feature set, and deep extensibility through JSONB, full text search, and foreign data wrappers. PostgreSQL 18 continues that lineage with further gains in query planning, vacuum efficiency, and logical replication, serving transactional and analytical workloads alike.
About Rocky Linux 9
Built directly from RHEL 9 source code for binary compatibility with the Red Hat 9 ecosystem, with predictable update cadences and a maintenance lifecycle through 2032. Any application compiled, certified, or documented for RHEL 9 runs without modification, and the platform is structurally aligned with AlmaLinux, CentOS Stream, and legacy CentOS deployments.
Highlights
- PostgreSQL 18 on a DISA STIG Hardened Base: 339 security controls applied to the Rocky Linux 9.8 foundation via the SCAP Security Guide, incorporating SSH hardening, kernel command line and module blocklists, and strict password policies out of the box.
- Verifiable Evidence Pack and SBOM: A 12-file OpenSCAP evidence pack ships inside the image, with before/after scan reports, itemized exceptions and justifications, NIST SP 800-53 mapping, CVE scan, and a complete SPDX Software Bill of Materials.
- PostgreSQL 18: Best-practice deployment. Packaged on a minimal, bloat-free installation - on an EC2-tuned base with TCP BBR and Red Hat tuned cloud profiles, rebuilt bi-weekly to monthly with upstream security patches.

Dimensions summary
You pay by the hour for this hardened PostgreSQL-18 image running on Rocky Linux 9. Pricing is not tiered by feature. Instead, each dimension maps to a specific AWS EC2 instance type, and your rate follows the size and family you choose. Small general-purpose instances cost less per hour, while large, memory-optimized, compute-optimized, storage, or GPU/accelerated instances cost more. You select the instance that fits your workload's CPU, memory, and storage needs. Software billing runs alongside the underlying AWS infrastructure charge. You can stop the instance to stop hourly software charges.
Top-of-mind questions for buyers
Each dimension maps to one AWS EC2 instance type running the hardened PostgreSQL-18 image on Rocky Linux 9. Your hourly rate reflects that instance's size and family. The vendor applies security hardening following standards like CIS Benchmarks, with kernel and network tuning built into the image.
Two charges apply per running hour and add together. The software licence meters the hardened PostgreSQL-18 image. The underlying AWS charge covers the EC2 instance itself. Both accrue simultaneously while the instance runs. The instance family and size you pick drive both charges upward together.
Hourly software charges apply only while the instance runs. Stopping the instance stops the software meter. Stopped instances may still incur AWS storage fees for attached volumes, but the software licence meters running time only. Restarting resumes hourly software billing at the same instance rate.

Usage instructions
Connection Methods
Once launched, SSH into the instance. The default username is 'rocky'. You can switch to the root user environment by running: sudo su -
Install Information
- OS: Rocky Linux 9
- PostgreSQL: 18
- Config File: '/var/lib/pgsql/18/data/postgresql.conf'
Usage Instructions
-
Access the database (peer authentication): This AMI uses PostgreSQL's official default peer authentication, so the 'postgres' database user has no password. Log in locally by running: sudo -u postgres psql
-
Run a query: Once inside the psql prompt, verify connectivity with: SELECT version();
-
Remote or password access (optional): By default only localhost is allowed. To enable password authentication and remote access, edit '/var/lib/pgsql/18/data/postgresql.conf' (listen_addresses) and '/var/lib/pgsql/18/data/pg_hba.conf' (authentication rules), then open port 5432 in the Security Group.
-
Manage the service: Use 'sudo systemctl start/stop/restart/status postgresql-18' to control the database service.
Firewall Configuration
-
SSH (Port 22): Required for initial system access.
-
PostgreSQL Database (Port 5432): Required for client connections to the database (localhost only by default; see step 3 to enable remote access).
-
Security Recommendation: For production environments, strictly limit access to these ports to trusted IP addresses only via cloud Security Groups or the local firewall.
