<div dir="ltr"><div><div><div><div>Due to a major re-organization at work, we are reviewing and/or implementing some new security policies. I personally think some of the proposed policies are not going to help security at all. So I thought I would take a survey to see what policies/practices are in place at other businesses. These are specific to UNIX/Linux systems. Active Directory users need not respond.<br>
<br></div>1. How long do your passwords need to be? Are you required to have non-alphabetic characters? How many passwords do you have to cycle through before you can re-use a password? Do you have a centralized authentication system? If you don't have centralized authentication, can you use the same password on all UNIX/Linux systems?<br>
<br></div>2. How often do you need to change passwords? Do you have any policy which allows exceptions to the password change frequency?<br><br></div>3. If you are allowed to use public keys, are you required to replace your keys on some sort of schedule?<br>
<br></div>Thanks.<br><br></div>
