- To improve consistency, efficiency, accuracy, and automation of our STIGs, we are moving towards the adoption of the Security Content Automation Protocol (SCAP). The move to an eXtensible Configuration Checklist Description Format (XCCDF) formatted STIG provides the ability for the consumption of the STIGs by the various automated assessment tools, such as Host Based Security System (HBSS). This content not only can be consumed by these tools, but can also provide the detailed information on how to
assess the system to determine compliance with the STIG requirement. This automation is only possible when Open Vulnerability Assessment Language (OVAL) code is available for the check being performed.
The STIGs will now be in extensible markup language (XML) format and include an
XSL Transformations (XSLT) file to make the XML look more like a normal STIG.
Some of the MS Word documents that were a part of the STIG will no longer be
provided. There may be some MS Word documents included in the STIG zip file that
contains introductory and background information that cannot be placed in the XML at this time. This would include such things as screen captures that help make the manual review process easier to understand.
The STIG will be packaged in a zip file that contains numerous files. There will be a readme file included in the zip file which is unique to that particular STIG. The readme.txt file will document the specific files for that technology. Generally the following files will be included in the zip file (names may vary):
Readme.txt - Important info about the files for the particular technology.
STIG manual.xml - This is the STIG XML file that contains the manual check
STIG benchmark-xccdf.xml - This is the STIG XML file that contains the automated
check procedures, and not the manual procedures. This file is only included for
technologies that contain OVAL checks.
STIG.xsl - This is the transformation file that will allow the XML to be presented in a "human friendly format".
Technology Overview.doc or .pdf - This file will contain the introductory and
background information, as well as screen captures, network diagrams, and other
important information that could not be stored in the XML file.
STIG-OVAL.xml - This file contains the detailed OVAL check code. This will only be provided if OVAL exists for the technology.
STIG-CPE-OVAL.xml - This is OVAL code that will provide information to the tool on how to check to see if the product being evaluated exists on the system.
STIG-CPE-DICTIONARY.xml - This is the file that contains the CPE information about the product.
