Week 2

How are passwords stored?

• As hashes

• Encrypted

• Plain text

• All of the above

Which one of the following is true for hashing functions?

• They encrypt plaintext

• They are reversible

• They cannot be reverted

• They are not complex

Which one of the following is the best hashing function?

• MD5

• TGF65

• SHA2

• None of the above

When should you use a dictionary attack?

• Single Word Passwords

• Random Sequences

• Multi word passwords

• Hashed Passwords

What can you use to stop most password attacks?

• Password policies

• Password resets

• Hashing

• MFA/2FA

Which problem can't be solved with a password manager?

• Creating strong passwords

• Remembering all passwords

• Logging into your computer (eg. Windows login)

• None of the above

Why should you use a password manager?

• It allows you to create strong and unique passwords for every platform you use, without remembering them

• It's faster to fill out login forms

• So my passwords won't get stolen

• All of the above

What is the best way to handle a data breach?

• Ignore it and hide it from the public

• Notify all users to change their passwords

• Delete all affected users

• Change the setup

What is the purpose of using multi-factor authentication (MFA) or two-factor authentication (2FA)?

• To make login processes more complicated

• To provide an additional layer of security beyond passwords

• To store passwords securely

• To make passwords easier to remember

How does encryption differ from hashing in terms of password security?

• Encryption is irreversible while hashing is reversible

• Encryption is used for storing passwords while hashing is used for data transmission

• Encryption requires a key to decrypt while hashing does not

• Encryption ensures data integrity while hashing ensures password confidentiality
