Strong user passwords help defend against attacks involving brute force guessing.
Oracle Solaris has a number of features that you can use to configure user passwords to your site requirements. You can specify password length, content, frequency of change, and modification requirements, and keep a password history. A dictionary of passwords to be avoided is provided. Several possible password hash algorithms are available. The default is SHA256.
