# Ansible Playbook for NIST National Checklist Program Security Guide
#
# Profile Description:
# This compliance profile reflects the core set of security
# related configuration settings for deployment of Oracle Linux 7 into U.S.
# Defense, Intelligence, and Civilian agencies. Development partners and
# sponsors include the U.S. National Institute of Standards and Technology
# (NIST), U.S. Department of Defense, the National Security Agency, and Red Hat.
# This baseline implements configuration requirements from the following
# sources:
# - Committee on National Security Systems Instruction No. 1253 (CNSSI 1253)
# - NIST Controlled Unclassified Information (NIST 800-171)
# - NIST 800-53 control selections for MODERATE impact systems (NIST 800-53)
# - U.S. Government Configuration Baseline (USGCB)
# - NIAP Protection Profile for General Purpose Operating Systems v4.2.1 (OSPP v4.2.1)
# - DISA Operating System Security Requirements Guide (OS SRG)
# For any differing configuration requirements, e.g. password lengths, the stricter
# security setting was chosen. Security Requirement Traceability Guides (RTMs) and
# sample System Security Configuration Guides are provided via the
# scap-security-guide-docs package.
# This profile reflects U.S. Government consensus content and is developed through
# the OpenSCAP/SCAP Security Guide initiative, championed by the National
# Security Agency. Except for differences in formatting to accommodate
# publishing processes, this profile mirrors OpenSCAP/SCAP Security Guide
# content as minor divergences, such as bugfixes, work through the
# consensus and release processes.
#
# Profile ID: xccdf_org.ssgproject.content_profile_ncp
# Benchmark ID: xccdf_org.ssgproject.content_benchmark_OL-7
# Benchmark Version: 0.1.80
# XCCDF Version: 1.2
#
# This file can be generated by OpenSCAP using:
# $ oscap xccdf generate fix --profile xccdf_org.ssgproject.content_profile_ncp --fix-type ansible ssg-ol7-ds.xml
#
# This Ansible Playbook is generated from an XCCDF profile without preliminary evaluation.
# It attempts to fix every selected rule, even if the system is already compliant.
#
# How to apply this Ansible Playbook:
# $ ansible-playbook -i "localhost," -c local playbook.yml
# $ ansible-playbook -i "192.168.1.155," playbook.yml
# $ ansible-playbook -i inventory.ini playbook.yml
