When creating a new password there is basic guidelines you should follow. Keep in mind that a strong password still does not replace the need for other effective security controls. I recently created a simple BASH script to generate passwords. This included all the basics steps to a strong password. (Shown below)
Strong password guidelines:
- 7+ characters in length.
- Does not contain a dictionary word.
- Includes both lowercase and uppercase characters.
- Must include a number.
- Must include a symbol.
After creating the password BASH script, I came across a tool called pwgen. Pwgen is a password generator that is included in the epel repository. It generates a list of secure passwords for you.
The description found in the man pages for pwgen is as follows:
The pwgen program generates passwords which are designed to be easily memorized by humans, while being as secure as possible. Human-memorable passwords are never going to be as secure as completely completely random passwords. In particular, passwords generated by pwgen without the -s option should not be used in places where the password could be attacked via an off-line brute-force attack. On the other hand, completely randomly generated passwords have a tendency to be written down, and are subject to being compromised in that fashion.
