# Ansible Playbook for ANSSI-BP-028 (high)
#
# Profile Description:
# This profile contains configurations that align to ANSSI-BP-028 v2.0 at the high hardening level.
# ANSSI is the French National Information Security Agency, and stands for Agence nationale de la sécurité des systèmes d'information.
# ANSSI-BP-028 is a configuration recommendation for GNU/Linux systems.
# A copy of the ANSSI-BP-028 can be found at the ANSSI website:
# https://www.ssi.gouv.fr/administration/guide/recommandations-de-securite-relatives-a-un-systeme-gnulinux/
#
# Profile ID: xccdf_org.ssgproject.content_profile_anssi_bp28_high
# Benchmark ID: xccdf_org.ssgproject.content_benchmark_OL-8
# 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_anssi_bp28_high --fix-type ansible ssg-ol8-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
