Security Technical Implementation Guides (STIGs) are the configuration hardening standards created by the Defense Information Systems Agency (DISA) to secure information systems and software. To make your systems compliant with STIG standards, you must install, configure, and test a variety of security settings. Image Builder provides STIG hardening components to help you more efficiently build compliant images for baseline STIG standards. These STIG components scan for misconfigurations and run a remediation script. There are no additional charges for using STIG-compliant components. **Important** With few exceptions, unless specified through parameters, STIG hardening components do not install third-party packages. If third-party packages are already installed on the instance, and if there are related STIGs that Image Builder supports for that package, the hardening component applies them. This page lists all STIGs that Image Builder supports that are applied to the EC2 instances that Image Builder launches when you build and test a new image. If you want to apply additional STIG settings to your image, you can create a custom component to configure it. For more information about custom components and how to create them, see [Use components to customize your Image Builder image](manage-components.md). When you create an image, the STIG hardening components log whether supported STIGs are applied or skipped. We recommend that you review the Image Builder logs for your images that use STIG hardening components. For more information about how to access and review Image Builder logs, see [Troubleshoot pipeline builds](troubleshooting.md#troubleshooting-pipelines). **Compliance levels** + **High (Category I) ** The most severe risk. Includes any vulnerability that can result in loss of confidentiality, availability, or integrity. + **Medium (Category II) ** Includes any vulnerability that can result in loss of confidentiality, availability, or integrity, but the risks can be mitigated. + **Low (Category III) ** Any vulnerability that degrades measures to protect against loss of confidentiality, availability, or integrity. **Topics** + [ ## Windows STIG hardening components ](#windows-os-stig) + [ ## STIG version history log for Windows ](#ib-windows-version-hist) + [ ## Linux STIG hardening components ](#linux-os-stig) + [ ## STIG version history log for Linux ](#ib-linux-version-hist) + [ ## SCAP compliance validator component ](#scap-compliance) ## Windows STIG hardening components AWSTOE Windows STIG hardening components are designed for standalone servers and apply Local Group Policy. STIG-compliant hardening components install and update the Department of Defense (DoD) certificates. They also remove unnecessary certificates to maintain STIG compliance. Currently, STIG baselines are supported for the following versions of Windows Server: 2012 R2, 2016, 2019, 2022, and 2025. This section lists current settings for each of the Windows STIG hardening components, followed by a version history log. ### Windows STIG Low (Category III) The following list contains STIG settings that the hardening component applies to your infrastructure. If a supported setting isn't applicable for your infrastructure, the hardening component skips that setting, and moves on. For example, some STIG settings might not apply to standalone servers. Organization-specific policies can also affect which settings the hardening component applies, such as a requirement for administrators to review document settings.

your infrastructure. If a supported setting isn't applicable for your infrastructure, the hardening component skips that setting, and moves on. For example, some STIG settings might not apply to standalone servers. Organization-specific policies can also affect which settings the hardening component applies, such as a requirement for administrators to review document settings. For a complete list of Windows STIGs, see the [STIGs Document Library](https://public.cyber.mil/stigs/downloads/?_dl_facet_stigs=windows).

If the Linux distribution doesn’t have STIG settings of its own, the hardening component applies RHEL settings. The Linux components have optional input parameters that help you customize the following behaviors for your Linux instance. + **Level (string)**   If no value is specified, the default is `High` and will apply all aplicable Low, Medium, and High configurations. + **InstallPackages (string)**   If the value is `No`, the component does not install any additional software packages. If the value is `Yes`, the component installs additional software packages that are required for maximum compliance. The default is `No`. + **SetDoDConsentBanner (string)**   If the value is `No`, the DoD consent banner is not shown when you attach to an instance that has one of the STIG Linux components installed. If the value is `Yes`, the DoD consent banner is shown before you log in when you attach to an instance that has one of the STIG Linux components installed. You must acknowledge the banner before you can log in. The default is `No`. For an example of the consent banner, see the [Disclaimer Department of Defense Privacy and Consent Notice](https://dso.dla.mil/) that appears when you access the DLA Document Services website. The hardening component applies supported STIG settings to the infrastructure based on the Linux distribution, as follows: **Red Hat Enterprise Linux (RHEL) 7 STIG settings** + RHEL 7 + CentOS 7 + Amazon Linux 2 (AL2) **RHEL 8 STIG settings** + RHEL 8 + CentOS 8 **RHEL 9 STIG settings** + RHEL 9 + CentOS Stream 9 ### Linux STIG Low (Category III) The following list contains STIG settings that the hardening component applies to your infrastructure. If a supported setting isn't applicable for your infrastructure, the hardening component skips that setting, and moves on. For example, some STIG settings might not apply to standalone servers. Organization-specific policies can also affect which settings the hardening component applies, such as a requirement for administrators to review document settings.

(Category I) The following list contains STIG settings that the hardening component applies to your infrastructure. If a supported setting isn't applicable for your infrastructure, the hardening component skips that setting, and moves on. For example, some STIG settings might not apply to standalone servers. Organization-specific policies can also affect which settings the hardening component applies, such as a requirement for administrators to review document settings. For a complete list, see the [STIGs Document Library](https://public.cyber.mil/stigs/downloads/?_dl_facet_stigs=operating-systems%2Cunix-linux).

The SCAP Compliance Checker (SCC) is a SCAP-validated scanning tool, released by the Naval Information Warfare Center (NIWC) Atlantic. For more information, see [Security Content Automation Protocol (SCAP) Compliance Checker (SCC)](https://www.niwcatlantic.navy.mil/Technology/SCAP/) on the *NIWC Atlantic* website. The AWSTOE `scap-compliance-checker-windows` and `scap-compliance-checker-linux` components download and install the SCC scanner on the pipeline build and test instances. When the scanner runs, it performs authenticated configuration scans using DISA SCAP Benchmarks, and provides a report that includes the following information. AWSTOE also writes the information to your application logs. + STIG settings that are applied to the instance. + An overall compliance score for the instance. We recommend that you run SCAP validation as the final step in your build process, to ensure that you report accurate compliance validation results. **Note** You can review the reports with one of the [STIG Viewing Tools](https://public.cyber.mil/stigs/srg-stig-tools/). These tools are available online via the DoD Cyber Exchange. The following sections describe the benchmarks that the SCAP validation components include. ### scap-compliance-checker-windows version 2024.03.0 The `scap-compliance-checker-windows` component runs on the EC2 instances that Image Builder creates to build and test the image. AWSTOE logs both the report and the score that the SCC application produces. The component performs the following workflow steps: 1. Downloads and installs the SCC application. 1. Imports the compliance benchmarks. 1. Runs validation using the SCC application. 1. Saves the compliance report and score locally on the build instance desktop. 1. Logs the compliance score from the local report to the AWSTOE application log files. **Note** AWSTOE currently supports SCAP compliance validation for Windows Server 2012 R2 MS, 2016, 2019, and 2022. The SCAP compliance checker component for Windows includes the following benchmarks: **SCC Version: 5.10** 2023 Q4 Benchmarks: + U\$1MS\$1Defender\$1Antivirus\$1V2R5\$1STIG\$1SCAP\$11-2\$1Benchmark + U\$1MS\$1DotNet\$1Framework\$14-0\$1V2R2\$1STIG\$1SCAP\$11-2\$1Benchmark + U\$1MS\$1IE11\$1V2R6\$1STIG\$1SCAP\$11-2\$1Benchmark + U\$1MS\$1Windows\$12012\$1and\$12012\$1R2\$1DC\$1V3R5\$1STIG\$1SCAP\$11-2\$1Benchmark + U\$1MS\$1Windows\$12012\$1and\$12012\$1R2\$1MS\$1V3R5\$1STIG\$1SCAP\$11-2\$1Benchmark + U\$1MS\$1Windows\$1Defender\$1Firewall\$1V2R3\$1STIG\$1SCAP\$11-2\$1Benchmark + U\$1MS\$1Windows\$1Server\$12016\$1V2R7\$1STIG\$1SCAP\$11-2\$1Benchmark + U\$1MS\$1Windows\$1Server\$12019\$1V3R2\$1STIG\$1SCAP\$11-2\$1Benchmark + U\$1MS\$1Windows\$1Server\$12022\$1V2R2\$1STIG\$1SCAP\$11-2\$1Benchmark + U\$1CAN\$1Ubuntu\$120-04\$1LTS\$1V1R10\$1STIG\$1SCAP\$11-2\$1Benchmark + U\$1RHEL\$17\$1V3R15\$1STIG\$1SCAP\$11-3\$1Benchmark + U\$1RHEL\$18\$1V1R13\$1STIG\$1SCAP\$11-3\$1Benchmark + U\$1RHEL\$19\$1V2R1\$1STIG\$1SCAP\$11-3\$1Benchmark ### scap-compliance-checker-linux version 2021.04.0 The `scap-compliance-checker-linux` component runs on the EC2 instances that Image Builder creates to build and test the image.
