+# CIS 5.4.1.1 Ensure password expiration is 90 days or less (Scored)
+#
+# Description
+# ===========
+# The PASS_MAX_DAYS parameter in /etc/login.defs allows an administrator to
+# force passwords to expire once they reach a defined age. It is recommended
+# that the PASS_MAX_DAYS parameter be set to less than or equal to 90 days.
+#
+# Rationale
+# =========
+# The window of opportunity for an attacker to leverage compromised credentials
+# or successfully compromise credentials via an online brute force attack is
+# limited by the age of the password. Therefore, reducing the maximum age of a
+# password also reduces an attacker's window of opportunity.
+#
+# Audit
+# =====
+# Run the following command and verify PASS_MAX_DAYS is 90 or less:
+#
+#   # grep PASS_MAX_DAYS /etc/login.defs
+#   PASS_MAX_DAYS 90
+#
+# Verify all users with a password have their maximum days between password
+# change set to 90 or less:
+#
+#   # egrep ^[^:]+:[^\!*] /etc/shadow | cut -d: -f1
+#   <list of users>
+#   # chage --list <user>
+#   Maximum number of days between password change: 90
+#
+# Remediation
+# ===========
+# Set the PASS_MAX_DAYS parameter to 90 in /etc/login.defs :
+#
+#   PASS_MAX_DAYS 90
+#
+# Modify user parameters for all users with a password set to match:
+#
+#   # chage --maxdays 90 <user>
+#
+# Notes
+# =====
+# You can also check this setting in /etc/shadow directly. The 5th field
+# should be 90 or less for all users with a password.

+# Description

+# The PASS_MIN_DAYS parameter in /etc/login.defs allows an administrator to

+# CIS 5.4.4 Ensure default user umask is 027 or more restrictive (Scored)
+#
+# Description
+# ===========
+# The default umask determines the permissions of files created by users.
+# The user creating the file has the discretion of making their files and
+# directories readable by others via the chmod command. Users who wish to
+# allow their files and directories to be readable by others by default may
+# choose a different default umask by inserting the umask command into the
+# standard shell configuration files ( .profile , .bashrc , etc.) in their
+# home directories.
+#
+# Rationale
+# =========
+# Setting a very secure default value for umask ensures that users make a
+# conscious choice about their file permissions. A default umask setting of
+# 077 causes files and directories created by users to not be readable by
+# any other user on the system. A umask of 027 would make files and
+# directories readable by users in the same Unix group, while a umask of 022
+# would make files readable by every user on the system.
+#
+# Audit
+# =====
+# Run the following commands and verify all umask lines returned are 027 or
+# more restrictive.
+#
+#   # grep "^umask" /etc/bash.bashrc
+#   umask 027
+#   # grep "^umask" /etc/profile
+#   umask 027
+#
+# Remediation
+# ===========
+# Edit the /etc/bash.bashrc and /etc/profile files (and the appropriate files
+# for any other shell supported on your system) and add or edit any umask
+# parameters as follows:
+#
+#   umask 027
+#
+# Notes
+# =====
+# The audit and remediation in this recommendation apply to bash and shell.
+# If other shells are supported on the system, it is recommended that their
+# configuration files also are checked.
+#
+# Other methods of setting a default user umask exist however the shell
+# configuration files are the last run and will override other settings if
+# they exist therefore our recommendation is to configure in the shell
+# configuration files. If other methods are in use in your environment they
+# should be audited and the shell configs should be verified to not override.
