Create A Strong Password
One way to create a good, strong password, is to use part of a phrase that is easy for you to remember. This phrase can be a set of words taken from a book, a song, a quotation, a statement, or anything else that you always easily remember. This phrase should be easy for you, but no one else should ever think about attributing it to you. Below are some examples of how to create strong passwords.

A common way to gain access to a network is to find a user's password, often by simple guessing. Attackers often setup automated programs to try and guess passwords on systems they find accessible from the internet. These attacks are called dictionary attacks and can be very effective. Here are some of the most common passwords we've observed attackers trying to use on our network:
If your password looks similar to these then you should change it immediately.
