# Ansible Playbook for Health Insurance Portability and Accountability Act (HIPAA)
#
# Profile Description:
# The HIPAA Security Rule establishes U.S. national standards to protect individuals’
# electronic personal health information that is created, received, used, or
# maintained by a covered entity. The Security Rule requires appropriate
# administrative, physical and technical safeguards to ensure the
# confidentiality, integrity, and security of electronic protected health
# information.
# This profile configures AlmaLinux 8 to the HIPAA Security
# Rule identified for securing of electronic protected health information.
# Use of this profile in no way guarantees or makes claims against legal compliance against the HIPAA Security Rule(s).
#
# Profile ID: xccdf_org.ssgproject.content_profile_hipaa
# Benchmark ID: xccdf_org.ssgproject.content_benchmark_ALMALINUX-8
# Benchmark Version: 0.1.75
# XCCDF Version: 1.2
#
# This file can be generated by OpenSCAP using:
# $ oscap xccdf generate fix --profile xccdf_org.ssgproject.content_profile_hipaa --fix-type ansible ssg-almalinux8-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
