Passwords: Selecting and Changing
Most of our servers and computers are directly accessible from the internet and the security of our systems starts with each of us selecting a strong and suitable password. Password selection is not always easy, you want a password that is difficult for someone else to guess, but easy for you to remember.
- Never share your password with anyone, if they need an account they should ask for an account.
- Avoid using your username as your password.
- Avoid using the same password on multiple systems.
- Avoid using dictionary words or words from other languages.
- Change your password every six months or sooner.
Pointers for Password Selection
Avoid a string of characters in succession: 123456, ABCDEF, or !@#$%^ are examples of successives.
Good passwords contain 4 character classes. Character classes are the following:
- Uppercase character
- Lowercase Character
An example password method is to think of a phrase and adopt it for your use:
My pet Bird Cat Jamie is 9 years old!
From the above we could use the first character of each word to give us: MpBCJi9yo!
