Clean up of over permissioned IAM accounts on GCP infra in an automated way CureIAM is an easy-to-use, reliable, and performant engine for Least Privilege Principle Enforcement on GCP cloud infra. It enables DevOps and Security team to quickly clean up accounts in GCP infra that have granted permissions of more than what are required. CureIAM fetches the recommendations and insights from GCP IAM recommender, scores them and enforce those recommendations automatically on daily basic. It takes care of scheduling and all other aspects of running these enforcement jobs at scale. It is built on top of GCP IAM recommender APIs and Cloudmarker framework. Key features Discover what makes CureIAM scalable and production grade. Config driven : The entire workflow of CureIAM is config driven. Skip to Config section to know more about it. Scalable : Its is designed to scale because of its plugin driven, multiprocess and multi-threaded approach. Handles Scheduling: Scheduling part is embedded in CureIAM code itself, configure the time, and CureIAM will run daily at that time note. Plugin driven: CureIAM codebase is completely plugin oriented, which means, one can plug and play the existing plugins or create new to add more functionality to it. Track actionable insights: Every action that CureIAM takes, is recorded for audit purpose, It can do that in file store and in elasticsearch store. If you want you can build other store plugins to push that to other stores for tracking purposes. Scoring and Enforcement: Every recommendation that is fetch by CureIAM is scored against various parameters, after that couple of scores like safe_to_apply_score, risk_score, over_privilege_score. Each score serves a different purpose. For safe_to_apply_score identifies the capability to apply recommendation on automated basis, based on the threshold set in CureIAM.yaml config file. Usage Since CureIAM is built with python, you can run it locally with these commands. Before running make sure to have a configuration file ready in either of /etc/CureIAM.yaml, ~/.CureIAM.yaml, ~/CureIAM.yaml, or CureIAM.yaml and there is Service account JSON file present in current directory with name preferably cureiamSA.json. This SA private key can be named anything, but for docker image build, it is preferred to use this name. Make you to reference this file in config for GCP cloud. # Install necessary dependencies$ pip install -r requirements.txt# Run CureIAM now$ python -m CureIAM -n# Run CureIAM process as schedular$ python -m CureIAM# Check CureIAM help$ python -m CureIAM --help CureIAM can be also run inside a docker environment, this is completely optional and can be used for CI/CD with K8s cluster deployment. # Build docker image from dockerfile$ docker build -t cureiam . # Run the image, as schedular$ docker run -d cureiam # Run the image now$ docker run -f cureiam -m cureiam -n Config CureIAM.yaml configuration file is the heart of CureIAM engine. Everything that engine does it does it based on the pipeline configured in this config file. Let's break this down in different sections to make this config look simpler. Let's configure first section, which is logging configuration and scheduler configuration. logger: version: 1 disable_existing_loggers: false formatters: verysimple: format: >- [%(process)s] %(name)s:%(lineno)d - %(message)s datefmt: "%Y-%m-%d %H:%M:%S" handlers: rich_console: class: rich.logging.RichHandler formatter: verysimple file: class: logging.handlers.TimedRotatingFileHandler formatter: simple filename: /tmp/CureIAM.log when: midnight encoding: utf8 backupCount: 5 loggers: adal-python: level: INFO root: level: INFO handlers: - rich_console - file schedule: "16:00" This subsection of config uses, Rich logging module and schedules CureIAM to run daily at 16:00. Next section is configure different modules, which we MIGHT use in pipeline. This falls under plugins section in CureIAM.yaml. You can think of this section as declaration for different plugins. plugins: gcpCloud: plugin: CureIAM.plugins.gcp.gcpcloud.GCPCloudIAMRecommendations params: key_file_path: cureiamSA.json filestore: plugin: CureIAM.plugins.files.filestore.FileStore gcpIamProcessor: plugin: CureIAM.plugins.gcp.gcpcloudiam.GCPIAMRecommendationProcessor params: mode_scan: true mode_enforce: true enforcer: key_file_path: cureiamSA.json allowlist_projects: - alpha blocklist_projects: - beta blocklist_accounts: - foo@bar.com allowlist_account_types: - user - group - serviceAccount blocklist_account_types: - None min_safe_to_apply_score_user: 0 min_safe_to_apply_scor e_group: 0 min_safe_to_apply_score_SA: 50 esstore: plugin: CureIAM.plugins.elastic.esstore.EsStore params: # Change http to https later if your elastic are using https scheme: http host: es-host.com port: 9200 index: cureiam-stg username: security password: securepassword Each of these plugins declaration has to be of this form: plugins: <plugin-name>: plugin: <class-name-as-python-path> params: param1: val1 param2: val2 For example, for plugins CureIAM.stores.esstore.EsStore which is this file and class EsStore. All the params which are defined in yaml has to match the declaration in __init__() function of the same plugin class. Once plugins are defined , next step is to define how to define pipeline for auditing. And it goes like this: audits: IAMAudit: clouds: - gcpCloud processors: - gcpIamProcessor stores: - filestore - esstore Multiple Audits can be created out of this. The one created here is named IAMAudit with three plugins in use, gcpCloud, gcpIamProcessor, filestores and esstore. Note these are the same plugin names defined in Step 2. Again this is like defining the pipeline, not actually running it. It will be considered for running with definition in next step. Tell CureIAM to run the Audits defined in previous step. run: - IAMAudits And this makes the entire configuration for CureIAM, you can find the full sample here, this config driven pipeline concept is inherited from Cloudmarker framework. Dashboard The JSON which is indexed in elasticsearch using Elasticsearch store plugin, can be used to generate dashboard in Kibana.
