# Ansible Playbook for DRAFT - Protection Profile for General Purpose Operating Systems
#
# Profile Description:
# This profile reflects mandatory configuration controls identified in the
# NIAP Configuration Annex to the Protection Profile for General Purpose
# Operating Systems (Protection Profile Version 4.2.1).
# This configuration profile is consistent with CNSSI-1253, which requires
# U.S. National Security Systems to adhere to certain configuration
# parameters. Accordingly, this configuration profile is suitable for
# use in U.S. National Security Systems.
#
# Profile ID: xccdf_org.ssgproject.content_profile_ospp
# 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_ospp --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
