# Rule ID: RHEL-06-000053_rule
# Severity: medium
# Rule Version (STIG-ID): RHEL-06-000053
# Rule Title: User passwords must be changed at least every 60 days.
#
# Vulnerability Discussion: Setting the password maximum age ensures 
# users are required to periodically change their passwords. This could 
# possibly decrease the utility of a stolen password. Requiring shorter 
# password lifetimes increases the risk of users writing down the password 
# in a convenient location subject to physical compromise.
#
# Responsibility: 
# IAControls: 
#
# Check Content:
#
# To check the maximum password age, run the command: 

# $ grep PASS_MAX_DAYS /etc/login.defs

# The DoD requirement is 60. 
# If it is not set to the required value, this is a finding.
#
# Fix Text: 
#
# To specify password maximum age for new accounts, edit the file 
# "/etc/login.defs" and add or correct the following line, replacing [DAYS] 
# appropriately: 

# PASS_MAX_DAYS [DAYS]

# The DoD requirement is 60.
