Unit 4 – Question 4


To keep us from cyber attacks that could breach data. We will explore some useful security measures to protect ourselves and others from cyber attacks.

How to set a password that is strong and secure enough?

The best passwords will thwart brute force and dictionary attacks, but it’s also possible to make them easy to remember. Try these password ideas to make your accounts unbreakable.

Stay away from the obvious. Never use sequential numbers or letters, and for the love of all things cyber, do not use “password” as your password. Come up with unique passwords that do not include any personal info such as your name or date of birth. If you’re being specifically targeted for a password hack, the hacker will put everything they know about you in their guess attempts.

Example: 123456, 123456789, password, acb123, 123123…

Can it be brute force attacked?

Keeping in mind the nature of a brute force attack, you can take specific steps to keep the brutes at bay:

  • Make it long. This is the most critical factor. Choose nothing shorter than 15 characters, more if possible.
  • Use a mix of characters. The more you mix up letters (upper-case and lower-case), numbers, and symbols, the more potent your password is, and the harder it is for a brute force attack to crack it.
  • Avoid common substitutions. Password crackers are hip to the usual substitutions. Whether you use DOORBELL or D00R8377, the brute force attacker will crack it with equal ease. These days, random character placement is much more effective than common leetspeak* substitutions. (*leetspeak definition: an informal language or code used on the Internet, in which standard letters are often replaced by numerals or special characters.)
  • Don’t use memorable keyboard paths. Much like the advice above not to use sequential letters and numbers, do not use sequential keyboard paths either (like qwerty). These are among the first to be guessed.
