Unit 4 – Question 2


Unit 4 – Question 2: Create or find a classroom resource that teaches students about creating strong passwords, passcodes or passphrases.

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.

* Password

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.

Can it be dictionary attacked?

The key to staving off this type of attack is to ensure the password is not just a single word. Multiple words will confuse this tactic — remember, these attacks reduce the possible number of guesses to the number of words we might use to the exponential power of the number of words we are using. What is a strong password? Strong passwords are the ones that are difficult to guess and often require a mix of uppercase, lowercase, numbers and symbols. Strongest passwords require a minimum of 16 characters, however, a password between 8 and 16 characters is said to provide a good level of security. We know what makes a solid password, and we have our favorite methods to create them. The methods below give you some good password ideas to create your own strong, memorable passwords.  Follow one of these handy tips, and you’ll be doubling down on protecting your digital world.

* Passphrase

A passphrase is similar to a password in usage, but it is longer and more secure. There are different guidelines to determine the length of a passphrase. Most passphrases have a minimum requirement of 14 characters. A passphrase can be a phrase that the user can easily remember but is difficult to be guessed by others. Passphrases can have upper and lower case characters, blanks and special characters.

Some example passphrases are: “Ilikestudyinglop11”, “Let’sstartat7o’clock”.

For password: “Ilikestudyinglop11”. It would take a computer about 1 hundred trillion years to crack your password

For password: “Let’sstartat7o’clock”. It would take a computer about 1 hundred quintillion years to crack your password
