The STIG Compliance Automation Repository (SCAR) is a framework for managing and deploying STIG-compliant DSC Configurations at scale within an existing Active Directory environment. SCAR scans Active Directory to identify systems and their applicable STIGs, builds PowerSTIG configurationdata for each machine, automates the generation for ATO/CCRI documentation (STIG Checklists), and can also parse and report on STIG compliance via PowerBI.

SCAR accelerates Azure readiness and ATO/CCRI processes through automated STIG compliance and digital transformation by establishing an infrastructure as code platform that organizations can customize build on top of to quickly establish and deploy Azure baselines.

The NodeData folder stores Powershell Data files that represent the end nodes that you are targetting. Each NodeData .psd1 file should contain the following:

• NodeName - The Active Directory Computer Name of the target node. This is used by DSC to push the configuration MOF to that machine.
• LocalConfigurationManager Hashtable - Define the Local Configuration Manager settings for your end node(s).
• AppliedConfigurations Array - Define which configurations you want to apply to your end node(s).
• Parameter Hashtables - Use hashtables with Parameter values for each configuration you're applying.
• Example:

    @{
        NodeName = "vm-jump-001"

        AppliedConfigurations  =
        @{

• NodeName - Specifies the name of the system.
• ManualStigs Array - Specify STIGs that cannot be automated via PowerSTIG. Example: Cisco STIGs.
• StigChecklist_Type Hashtables - Use hashtables starting with "StigChecklist_" and specify the folder name(s) containing the xccdf(s) and Manual Check files of those STIGs, and use a "Subtypes" array to specify multiple STIGs within those folders.
• Example:

    @{
        NodeName = "CiscoSwitch"

        ManualStigs =
        @{

            StigChecklist_Cisco  =

            }
        }
    }

Standardized configuration scripts should be located in the Configurations folder. Follow these guidlines for your configurations:

• Each configuration should be named the exact same as the file name.
• Use parameters for settings that allow for variance.

• DscConfigs: Running Start-DscBuild will generate a custom/compiled DSC Configuration script for each system with a nodedata file.
• MOFs: Start-DscBuild also executes each compiled script in the DSCConfigs folder to generate a cutomized MOF for each system.
• Stig Checklists: Get-StigChecklists will execute a compliance SCAN for every system in the nodedata folder and will generate a STIG Checklist (.ckl) file for each PowerSTIG configuration defined in the system's nodedata.

The resources folder is used to store Powershell Modules, DSC Resource Modules, helper functions, etc that are relevent to your organization.

Build/Release functions for DSCSM are also stored in the resources folder.
