Password : how to make a good one

IT security is about balancing security (keeping your stuff as yoursi, assesing and managing risk, etc.) with productivity (ease of use, being able to do your work, etc.).

What are the risks?

Someone who discovers/guesses/captures your password could:

Creating a good password

A good password will use the whole character set. This means at least one of each of: upper case latter, lower case letter, a number and a punctuation character.

Use something like 747!aDa (the use of upper and lower case letters is recommended and a mix is required). You might choose two short unrelated words and join them together with punctuation: dat?Swan. Another technique is to use initial letters of a phrase (but one that is not too well known): Ptotlbl (do not use any of these example passwords yourself!)

A minimum password lenght of 10 characters is recommended.

Safely using your password

Do not use your name or initials, your logon name, your telephone number, a common English or foreign word, or any of these reversed or repeated. Programs exist which can crack such passwords.

Do not keep using the password given to you initially. Set a new personal password when you first log on. Do not write your password down, do not let anyone watch you typing it in, and do not keep a copy on the computer!

You must not give your password to anyone else for whatever reason. If you wish to share information with a colleague there are ways of doing this safely without compromising your password. If in doubt ask IT Support.

Do not use your AEI password on other computer systems.
