# Ansible Playbook for Standard System Security Profile for Oracle Linux 8
#
# Profile Description:
# This profile contains rules to ensure standard security baseline
# of Oracle Linux 8 system. Regardless of your system's workload
# all of these checks should pass.
#
# Profile ID:  xccdf_org.ssgproject.content_profile_standard
# 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_standard --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
