This tutorial is part of our tutorial series on WordPress Security. In this tutorial, we look at how improving basic security practices like password security can contribute to your overall web security.
One of the most common methods used by hackers to crack into websites, computers, servers, etc. is to run brute-force attack software persistently on login areas, looking for weak password combinations.
Many potential vulnerabilities can be avoided with good security habits. Using strong passwords is one of the first and most important security habits you can develop.
A strong password is not only necessary to protect your website, but your entire online presence. A hacker who gains access to your computer administrator account is able to install malicious scripts that can potentially compromise your entire server.
Creating A Strong Password
The goal with creating strong passwords is to make it hard for other people to guess them and hard for a brute force attack to succeed.
Strong Password Foundations
To create a strong password, keep the following in mind:
- Avoid any permutation of your own real name, username, company name, or name of your website. You also should avoid choosing a simple password like your child’s name or your pet’s name.
- Avoid using words from a dictionary, in any language.
- Don’t use short passwords. Make your passwords long (over 8 characters) whenever possible. The longer the password you have, the stronger it is. 8 – 12 character passwords are ideal. See the ‘Password-Permutation’ section below for more details.
- Avoid using numeric-only or alphabetic-only password. A mixture of both is best. Use a combination of uppercase, lowercase, numbers and non-alphanumeric characters. Non-alphanumeric characters are symbols like: $, #, [, %,^,&,}, ~, /, *, @, etc…
- Even though you have probably heard this a million times before, it is worth repeating it again: Don’t use the same password for all your websites and logins.
- Elaborate, strong passwords are not going to be easy to remember. Consider using a password management tool (see below).
Strong Password Generators
Many password generators are available that can be used to automatically create secure passwords.
You can find free secure password generators online …
You can also create passwords using password management tools such as RoboForm …
RoboForm is a powerful tool that helps you manage multiple passwords easily and access all of your logins with a single click from your desktop PC, laptop or mobile device …
To learn more about password management software, see the tutorial below:
WordPress also features a password strength meter which is shown when changing your password in WordPress. Use this feature when changing your password to ensure the strength of your password is adequate …
In password security terms, ‘permutation’ refers to the number of possible combinations of characters, numbers, symbols, etc. that it would take for someone to decode a password.
For example, if you have a 3-character password using only the numbers 1, 2, and 3 and they are allowed to repeat, then there are 27 possible password permutations, as shown below:
The permutation formula for a 3-character password where the password characters are allowed to repeat is as follows:
If your password is only three characters long, and you use all 26 characters from the English alphabet, then the number of permutations required to decode your password are as follows:
Any hacker using a brute-force attack software and a computer with minimal processing power can crack the above password in no time.
Adding just one more character to your password, however, can increase the magnitude and complexity of your password to a level that would make it significantly more difficult for hackers to crack, as shown below …
As you can see, increasing your password length by just one character makes it significantly more difficult to crack.
An 8-character password that uses all 26 letters of the English alphabet plus 10 numbers (0 – 9) creates the following number of possible combinations …
When you add in a combination of uppercase and lowercase letters, plus non-alphanumeric characters (e.g. $, #, [, %,^,&,}, ~, /, *, @, etc.) to a case-sensitive password, then you can see just how significantly increased the magnitude of your password security will be.
Make sure to implement strong password security measures for all of your online access points. This includes:
- Online Accounts Password Security
- WordPress Password Security
- WordPress Database Password Security
- Computer Password Security
Additionally, make sure to research and implement or review the following security measures in your specific setup …
- Email Password Security
- FTP Password Security
- Web Server / Web Hosting Security
Hopefully, the above will help you understand how improving basic security practices like password security can contribute to your overall web security and why using strong passwords for your online assets makes it more difficult for hackers to crack your passwords and breach your security measures.
