# Bash Remediation Script for DRAFT - Unclassified Information in Non-federal Information Systems and Organizations (NIST 800-171)
#
# Profile Description:
# From NIST 800-171, Section 2.2:
# Security requirements for protecting the confidentiality of CUI in nonfederal
# information systems and organizations have a well-defined structure that
# consists of:
# (i) a basic security requirements section;
# (ii) a derived security requirements section.
# The basic security requirements are obtained from FIPS Publication 200, which
# provides the high-level and fundamental security requirements for federal
# information and information systems. The derived security requirements, which
# supplement the basic security requirements, are taken from the security controls
# in NIST Special Publication 800-53.
# This profile configures Oracle Linux 9 to the NIST Special
# Publication 800-53 controls identified for securing Controlled Unclassified
# Information (CUI)."
#
# Profile ID: xccdf_org.ssgproject.content_profile_cui
# Benchmark ID: xccdf_org.ssgproject.content_benchmark_OL-9
# 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_cui --fix-type bash ssg-ol9-ds.xml
#
# This Bash Remediation Script 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 Bash Remediation Script:
# $ sudo ./remediation-script.sh
