Overview
The CIS Hardened STIG Image on Red Hat Enterprise Linux 9 is a pre-configured image built by the Center for Internet Security (CIS®) for use on Amazon Elastic Compute Cloud (Amazon EC2). It is a pre-configured, security-hardened image that aligns with the robust security recommendations, the CIS Benchmarks, making it easier for organizations to meet regulatory requirements.
Not only is this image pre-hardened to the CIS Benchmarks guidance, but it is also patched monthly in alignment with the updates from the software vendor.
Key Benefits
Guidance from the DoD Cloud Computing SRG indicates that CIS Benchmarks are an acceptable alternative when DISA STIGs are not available. DISA STIGs are configuration standards for DoD Information Assurance (IA) and IA-enabled devices/systems. Launching an image that is hardened according to the CIS STIG Benchmark recommendations provides the ability to easily implement CIS guidance and DISA STIG at once. No packages are installed on or removed from this image outside of those already present on the base image or as recommended in alignment with the corresponding CIS Benchmark recommendations.
To demonstrate conformance to the CIS Red Hat Enterprise Linux 9 STIG Benchmark, industry-recognized hardening guidance, each image includes an HTML report from CIS Configuration Assessment Tool (CIS-CAT® Pro). Each CIS Hardened Image contains the following files:
These reports are located in /home/CIS_Hardened_Reports.

Dimensions summary
You pay by the hour for this hardened virtual machine image on Red Hat Enterprise Linux 9. Pricing is not tiered. Instead, each dimension maps to a specific AWS EC2 instance type, from small shared instances to large memory, compute, storage, and GPU instances, including bare metal options. Your hourly software rate depends on the instance type you launch. Larger or more specialized instances carry higher hourly rates. You run only the instances you need, and billing stops when you stop them. AWS infrastructure charges apply separately from this software rate.
Top-of-mind questions for buyers
Each hourly unit covers one running EC2 instance of the type you select. The instance runs a virtual machine image pre-configured to the CIS Benchmark security recommendations for Red Hat Enterprise Linux 9. You pay the software rate for each hour that instance runs.
The hourly software rate meters running time only. When you stop an instance, the software charge stops. Stopped instances may still incur separate AWS storage fees for the attached volumes. Those infrastructure charges are billed by AWS, not as part of this software rate.
Each running instance bills independently at the hourly rate tied to its instance type. Your total is the sum across all running instances. Larger or specialized instance types carry higher hourly software rates, so those instances contribute more to the bill than small shared types.

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.

Enhanced Security with Complex Setup
Reviewed on Nov 26, 2025
Review provided by G2
What do you like best about the product?
I appreciate the strong security features of CIS Red Hat Enterprise Linux, particularly how it revokes all access to non-root users. This significantly enhances the security by ensuring that unauthorized personnel cannot execute commands that could compromise the system. I also value the partition-level security it provides, such as setting 'noexec' and 'nosuid' options in the 'fstab' file for temporary partitions. This feature effectively prevents the automatic execution of programs, adding an additional layer of security to protect sensitive data. Moreover, the restrictions set for '/etc/fstab' are particularly beneficial for temporary partitions, which are often targeted by applications looking to execute programs. By disallowing execution on these partitions, it minimizes security risks and protects our telecom customers' environments more efficiently.
What do you dislike about the product?
I find handling the PAM authentication and audit services in CIS Red Hat Enterprise Linux to be quite confusing. While PAM is essential for Linux password restrictions, the complexity involved makes it cumbersome, and managing the necessary controls could be streamlined if handled separately. Additionally, the initial setup of the system is challenging due to numerous restrictions that must be kept in mind. This adds another layer of complexity, requiring careful application of changes or modifications, which reduces the overall user-friendliness.
What problems is the product solving and how is that benefiting you?
I use CIS Red Hat Enterprise Linux to enhance security, adding extra layers such as revoking access for non-root users and setting noexec nosuid on tmp partitions to prevent unauthorized execution.

What problems is the product solving and how is that benefiting you?
CIS almost locked all doors of entries. Sometimes an attacker filled the tmp file thru garbage data which halts the OS. in case of CIS benchmarked machine it helps you so that the application face challange due to unab le to generate data at tmp path
