InformationComplex passwords contain one character from each of the following classes: English uppercase letters, English lowercase letters, Westernized Arabic numerals, and non-alphanumeric characters.
Ensure that both uppercase and lowercase letters are part of the password policy on the computer.
The more complex a password the more resistant it will be against persons seeking unauthorized access to a system.
Password policy should be in effect to reduce the risk of exposed services being compromised easily through dictionary attacks or other social engineering attempts.
SolutionRun the following command to set passwords to require at upper and lower case letter:
$ sudo /usr/bin/pwpolicy -n /Local/Default -setglobalpolicy 'requiresMixedCase=<value>=1>'
$ sudo /usr/bin/pwpolicy -n /Local/Default -setglobalpolicy 'requiresMixedCase=1'
