The Oracle Linux operating system must be configured so that when passwords are changed or new passwords are assigned, the new password must contain at least one numeric character.

| Description | ||||
| Use of a complex password helps to increase the time and resources required to compromise the password. Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. Password complexity is one of several factors that determines how long it takes to crack a password. The more complex the password, the greater the number of possible combinations that must be tested before the password is compromised. | ||||

Details
Check Text (C-221671r1015168_chk)
Note: The value to require a number of numeric characters to be set is expressed as a negative number in "/etc/security/pwquality.conf".
Check the value for "dcredit" in "/etc/security/pwquality.conf" with the following command:
# grep dcredit /etc/security/pwquality.conf
dcredit = -1
If the value of "dcredit" is not set to a negative value, this is a finding.
Fix Text (F-23375r419086_fix)
Configure the operating system to enforce password complexity by requiring that at least one numeric character be used by setting the "dcredit" option.
Add the following line to /etc/security/pwquality.conf (or modify the line to have the required value):
dcredit = -1
