Microsoft Security DevOps (MSDO) is a command line application which integrates static analysis tools into the development cycle. MSDO installs, configures and runs the latest versions of static analysis tools (including, but not limited to, SDL/security and compliance tools). MSDO is data-driven with portable configurations that enable deterministic execution across multiple environments. For tools that output results in or MSDO can convert their results to SARIF, MSDO imports into a normalized file database for seamlessly reporting and responding to results across tools, such as forcing build breaks.

Note: This page describes how to configure the MSDO Action for GitHub workflows. For Azure DevOps task configuration, please see here.

How to Configure the Microsoft Security DevOps (MSDO) Action

MSDO Action Configuration

steps:
 - name: Run Microsoft Security DevOps
   uses: microsoft/security-devops-action@latest

Tool configuration options

This section contains all of the direct input options to tools (aka. analyzers).

There are a few ways configure tool inputs:

Creating a *.gdnconfig file to save configurations
1. Great for reuse between team members and local/remote runs
2. Can save multiple tool configurations in a single file to run all configurations. See the tool arguments section for additional details on defining .gdnconfig files.
Using environment variables
1. Great for quick configurations in build pipelines
2. They follow the format [GDN_]<ToolName>_<ArgumentId>, where GDN_ is optional and ToolName and ArgumentId are defined by the tool integration file to (*.gdntool).

The microsoft/security-devops-action will run all applicable analyzers configured in the policy. By default, this action runs the GitHub policy. If a file is found that MSDO has an analyzer for, it runs the analyzer with default settings against the target.

Configuring environment variables for tool configuration in GitHub

Tool variables can be set within GitHub Workflows.

They can be set as top level environment variables in the build:

env:
  <key>: '<value>'

job:
  ...

Or on the action itself.

steps:
- uses: microsoft/security-devops-action
  env:
    <key>: '<value>'

Here' an example action to configure the targets CLI option for eslint:

steps:
- uses: microsoft/security-devops-action
  env:
    eslint_targets: '**/*.js'

Checkov Environment Variables

Argument name	Environment variable name	Description
SkipPath	GDN_CHECKOV_SKIPPATH	Path (file or directory) to skip, using regular expression logic, relative to the current working directory. Word boundaries are not implicit; i.e., specifying “dir1” will skip any directory or subdirectory named “dir1”. Can be specified multiple times.
Directory	GDN_CHECKOV_DIRECTORY	IaC root directory (can not be used together with --file).
File	GDN_CHECKOV_FILE	File to scan (can not be used together with --directory). With this option, Checkov will attempt to filter the runners based on the file type. For example, if you specify a “.tf” file, only the terraform and secrets frameworks will be included. You can further limit this (e.g., skip secrets) by using the --skip-framework argument.
ExternalChecksDir	GDN_CHECKOV_EXTERNALCHECKSDIR	Directory for custom checks to be loaded. Can be repeated.
List	GDN_CHECKOV_LIST	List all checks that Checkov is scanning for.
Framework	GDN_CHECKOV_FRAMEWORK	Filter scan to run only on specific infrastructure code frameworks.
SkipFramework	GDN_CHECKOV_SKIPFRAMEWORK	Filter scan to skip specific infrastructure as code frameworks. This will be included automatically for some frameworks if system dependencies are missing. Add multiple frameworks using spaces.
Check	GDN_CHECKOV_CHECK	Checks to run; any other checks will be skipped. Enter one or more items separated by commas. Each item will be a Checkov check ID (CKV_AWS_123).
SkipCheck	GDN_CHECKOV_SKIPCHECK	Checks to skip; any other checks will not be run. Enter one or more items separated by commas. Each item will be a Checkov check ID
HardFailOn	GDN_CHECKOV_HARDFAILON	Exits with a non-zero exit code for specified checks. Enter one or more items separated by commas. Each item will be a Checkov check ID (CKV_AWS_123). --hard-fail-on takes precedence in a tie with skip check.
DownloadExternalModules	GDN_CHECKOV_DOWNLOADEXTERNALMODULES	Download external terraform modules from public git repositories and terraform registry

ESLint Environment Variables

Argument name	Environment variable name	Description
DisableDefaultConfigurationFile	GDN_ESLINT_DISABLEDEFAULTCONFIGURATIONFILE	Disables use of configuration from .eslintrc.* and package.json files. Default: true
ResolvePluginsRelativeTo	GDN_ESLINT_RESOLVEPLUGINSRELATIVETO	Specify the working directory from which to load the plugins. Default:CWD
ConfigurationFile	GDN_ESLINT_CONFIGURATIONFILE	Specify an additional configuration file for ESLint. This file will override existing configurations.
Environments	GDN_ESLINT_ENVIRONMENTS	Specify environments, e.g.: --env browser,node. See: https://eslint.org/docs/user-guide/configuring#specifying-environments
Extensions	GDN_ESLINT_EXTENSIONS	Specifies file extensions to scan.
Globals	GDN_ESLINT_GLOBALS	Specify global variables,so that they will not be flagged as undefined by the no-undef rule. Any specified global variables are assumed to be read-only by default, but appending :true to a variable's name ensures that no-undef will also allow writes. E.g.: --global require,exports:true
Parser	GDN_ESLINT_PARSER	Specify a parser to be used by ESLint. When using the SDL required/recommended config, @typescript-eslint/parser will be the default.
ParserOptions	GDN_ESLINT_PARSEROPTIONS	Specify parser options to be used by ESLint. Note that the available parser options are determined by the parser being used. E.g.: --parser-options=ecmaVersion:7
AdditionalRulesDirectories	GDN_ESLINT_ADDITIONALRULESDIRECTORIES	Specify other directories from which to load rules files.
Plugins	GDN_ESLINT_PLUGINS	Specifies plugins to load. You can omit the prefix eslint-plugin- fom the plugin name. Plugins must be installed using npm before being used.
Rules	GDN_ESLINT_RULES	Specify additional rules. These will be merged with any rules specified using other options.
Fix	GDN_ESLINT_FIX	Instructs ESLint to try to fix as many issues as possible. The fixes are made to the actual files themselves and only the remaining unfixed issues are output.
FixDryRun	GDN_ESLINT_FIXDRYRUN	Same as --fix, but instead of fixing the files, output the fixes.
FixTypes	GDN_ESLINT_FIXTYPES	Specify the types of fixes to apply. Choose from: problem, suggestion, layout. Multiple allowed, comma separated.
ExclusionsFilePath	GDN_ESLINT_EXCLUSIONSFILEPATH	Specify the file to use as your .eslintignore. By default, ESLint looks in the current working directory for .eslintignore. You can override this behavior by providing a path to a different file.
DisableExclusions	GDN_ESLINT_DISABLEEXCLUSIONS	Disables excluding of files from .eslintignore, --ignore-path and --ignore-pattern.
ExclusionPatterns	GDN_ESLINT_EXCLUSIONPATTERNS	This option allows you to specify patterns of files to ignore (in addition to those in .eslintignore). You can repeat the option to provide multiple patterns.E.g. eslint --ignore-pattern '/lib/' --ignore-pattern '/src/vendor/*' .
Quiet	GDN_ESLINT_QUIET	Disable reporting on warnings.
MaxWarnings	GDN_ESLINT_MAXWARNINGS	Specify a warning threshold, which can be used to force ESLint to exit with an error status if there are too many warning-level rule violations in your project.
ExitOnFatalError	GDN_ESLINT_EXITONFATALERROR	This option causes ESLint to exit with exit code 2 if one or more fatal parsing errors occur. Without this option, fatal parsing errors are reported as rule violations.
OutputFile	GDN_ESLINT_OUTPUTFILE	Specifies the path of the output file.
OutputFormat	GDN_ESLINT_OUTPUTFORMAT	Specifies the output format. Default: json.
DisableInlineConfig	GDN_ESLINT_DISABLEINLINECONFIG	This option prevents all inline comments like /eslint-disable/ or /global foo/ from having any effect.
ReportUnusedDisableDirectives	GDN_ESLINT_REPORTUNUSEDDISABLEDIRECTIVES	This option causes ESLint to report directive comments like // eslint-disable-line when no errors would have been reported on that line anyway.
Cache	GDN_ESLINT_CACHE	Only check changed files - default: false.
CacheLocation	GDN_ESLINT_CACHELOCATION	Path to the cache file or directory
Debug	GDN_ESLINT_DEBUG	Outputs debugging information to the console.
Help	GDN_ESLINT_HELP
Targets	GDN_ESLINT_TARGETS	Specifies the target files, directories or globs, as a space separated list.
