# Ansible remediation role for profile stig
# Profile Title: DISA STIG for Red Hat Enterprise Linux 8
# Profile Description:
# This profile contains configuration checks that align to the
# DISA STIG for Red Hat Enterprise Linux 8 V1R2.
#
# In addition to being applicable to Red Hat Enterprise Linux 8, DISA recognizes this
# configuration baseline as applicable to the operating system tier of
# Red Hat technologies that are based on Red Hat Enterprise Linux 8, such as:
#
# - Red Hat Enterprise Linux Server
# - Red Hat Enterprise Linux Workstation and Desktop
# - Red Hat Enterprise Linux for HPC
# - Red Hat Storage
# - Red Hat Containers with a Red Hat Enterprise Linux 8 image
#
# Benchmark ID: RHEL-8
# Benchmark Version: 0.1.57
#
# XCCDF Version: 1.1
#
# This file was generated by OpenSCAP 1.2.16 using:
# $ oscap xccdf generate fix --profile stig --template urn:xccdf:fix:script:ansible sds.xml
#
# This script is generated from an OpenSCAP profile without preliminary evaluation.
# It attempts to fix every selected rule, even if the system is already compliant.
#
# How to apply this remediation role:
# $ ansible-playbook -i "192.168.1.155," playbook.yml
# $ ansible-playbook -i inventory.ini playbook.yml
