Authentication Flashcards
Describe Zero login & biometrics.
Zero login & biometrics allows users to log in without a username and password by using biometric data like fingerprints, face, or gestures.
What are the advantages and disadvantages of Zero login & biometrics?
Advantage: Convenient for frequent logins, especially on smartphones.
Disadvantage: If compromised, biometric data cannot be changed, and recognition can fail.
Describe Magnetic stripe.
A magnetic stripe is a card contains unique data (e.g., ID, name) and is swiped through a card reader to authenticate users.
What are the advantages and disadvantages of Magnetic stripe?
Advantage: Easy and cheap to set up, can be used for multiple systems.
Disadvantage: Less secure, easily copied, and magnetic stripes wear out.
Describe Smart cards.
Smart cards are cards that enhance magnetic stripe cards by adding a microchip for contactless use, storing extra data like a PIN.
Describe Electronic Tokens.
Software tokens generated by an app that produce OTPs for user authentication, allowing secure access without physical devices.
What are the advantages and disadvantages of Physical Tokens?
Advantage: Very secure due to changing OTPs.
Disadvantage: Lack of compatibility can cause inconvenience.
Describe Physical Tokens.
A physical device used to authenticate a user remotely by generating a random one-time password (OTP) for secure access.
What are the advantages and disadvantages of Smart cards?
Advantage: More secure, faster transactions, and multi-purpose use.
Disadvantage: More expensive to manufacture.
What are the advantages and disadvantages of Electronic Tokens?
Advantage: More convenient as it eliminates the need for physical tokens.
Disadvantage: Requires a device that can run the application.
Describe OTP Generation in Physical Tokens.
Physical tokens generate a one-time password that users must enter to gain access, ensuring that access is time-sensitive and secure.
What are the advantages and disadvantages of OTP Generation in Electronic Tokens?
Advantage: Offers quick access and enhances security through app-based generation.
Disadvantage: Dependent on the availability of a mobile device and internet connectivity
What are passwords
Passwords are a digital lock to prevent unauthorised access to an account
What is encryption
Encryption is changing your raw text to a cypher text to protect sensitive data
