Amazon EC2 Windows Server AMIs for STIG compliance

Security Technical Implementation Guides (STIGs) are the configuration 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. Amazon EC2 Windows Server AMIs for STIG Compliance are pre-configured with over 160 required security settings. STIG-compliant operating systems include Windows Server 2012 R2, Windows Server 2016, and Windows Server 2019. The STIG-compliant AMIs include updated Department of Defense (DoD) certificates to help you get started and achieve STIG compliance. There are no additional charges for using STIG-compliant AMIs.

Amazon EC2 Windows Server AMIs for STIG compliance are available in all public AWS and GovCloud Regions. You can launch instances from these AMIs directly from the Amazon EC2 console. They are billed using standard Windows pricing.

The STIG-compliant Amazon EC2 AMIs for Windows Server can be found in the Community AMIs when you create an instance. The AMI names are as follows:

Note

The date suffix for the AMI (YYYY.MM.DD) is the date on which the latest version was created. You can search for the version without the date suffix.

• Windows_Server-2019-English-STIG-Full-YYYY.MM.DD

• Windows_Server-2012-R2-English-STIG-Core-YYYY.MM.DD

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 could result in loss of confidentiality, availability, or integrity but where the risks could be mitigated.

• Low (Category III)

  Includes any vulnerability that degrades measures to protect against loss of confidentiality, availability, or integrity.

The following sections show the STIGs that have been applied to Windows Operating Systems and components.

Core and base operating systems

STIG-compliant Amazon EC2 AMIs are designed for use as standalone servers, and have the highest level of STIG settings applied (Category 1). Each compliance level includes all STIG settings from lower levels, which means that the highest level has all applicable settings from all levels.

Some STIG settings are not automatically applied. This can be due to technical limitations – for instance, the STIG setting might not be applicable for standalone servers. Organization-specific policies can also prevent automatic application of STIG settings, such as a requirement for administrators to review document settings. For more details about which STIGs are applied to Amazon EC2 Windows AMIs, you can download our spreadsheet.
