How to enforce password complexity on Solaris

Posted May 12, 2012 - 07:44 pm

Solaris 10 is the first version of Solaris to provide a complex set of variables for controlling password strength. The /etc/default/passwd file contains a series of parameters -- most commented out when a system is first installed -- that allow you to exercise some fairly rigorous constraints on the passwords your users may select.

How to enforce password complexity on Linux

Posted May 06, 2012 - 08:17 pm

Enforcing password complexity involves making decisions about how long passwords need to be and whether they must contain a mix of characters -- such as digits, a mix of uppercase and lowercase, or special characters. In general, the rules are not hard to set up, but you need to know both the syntax and the rules to get the outcome you expect.

What makes a good password?

Posted Apr 29, 2012 - 05:02 pm

Sound advice against the use of bad passwords has been around for decades. Yet I still find people electing to use passwords like pa55w0rd and login123 as if they'd never heard about password cracking programs. Even technical professionals -- programmers, help desk techs and systems administrators -- sometimes assign really weak passwords to their own and other important accounts. It's become painfully obvious to me that telling people to use good passwords isn't enough. We need to clearly define what a good password is -- and never imply that short or predictable passwords are ever OK.

What is access governance?

Posted Apr 15, 2012 - 06:04 pm

Access governance is more than just the coolest concept since virtualization and cloud computing. It's likely to change the way you manage accounts on your servers. Designed to add clarity and control to questions like "Who has access to the recipe for our secret sauce?", it may be the answer to some of your biggest problems.
