NIST 800-53 playbooks now ship as part of RHEL and Fedora! This project is now EOL. The URL/repo will be archived on 1-JUNE-2018.
Official Red Hat security automation content, which includes SCAP and Ansible, is developed through the SCAP Security Guide project. The content is delivered natively in RHEL (yum install scap-security-guide
), available through the NIST National Checklist, or on Ansible Galaxy.
