| 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. Use of "pwquality" enforces complex password construction configuration and has the ability to limit brute-force attacks on the system. OL 8 uses "pwquality" as a mechanism to enforce password complexity. This is set in both of the following: /etc/pam.d/password-auth /etc/pam.d/system-auth Satisfies: SRG-OS-000069-GPOS-00037, SRG-OS-000070-GPOS-00038 |

Details
| Check Text (C-52120r902807_chk) |
| Verify the operating system uses "pwquality" to enforce the password complexity rules. Check for the use of "pwquality" in the password-auth file with the following command: $ sudo cat /etc/pam.d/password-auth | grep pam_pwquality password requisite pam_pwquality.so If the command does not return a line containing the value "pam_pwquality.so" as shown, or the line is commented out, this is a finding. |
| Fix Text (F-52074r902808_fix) |
| Configure the operating system to use "pwquality" to enforce password complexity rules. Add the following line to the "/etc/pam.d/password-auth" file (or modify the line to have the required value): password requisite pam_pwquality.so |
