2) Identification and Authentication Flashcards
(T/F) Multifactor authentication is the use of more than one authentication method to access an information system.
True
The claim of what someone or something is.
Identification
Establishes whether an identification claim is true.
Authentication
Something that supports our claim to identity, either in our personal interactions or in computer systems, e.g. social security cards.
Identity verification
Authentication requirements help prevent this crime.
Falsifying identification
A set of methods we use to establish a claim of identity as being true.
Authentication
A password is an example of this type of factor.
Something you know
An iris scan is an example of this type of factor.
Something you are
A swipe card is an example of this type of factor.
Something you have
The time delay between your keystrokes is an example of this type of factor.
Something you do
Being at a specific terminal is an example of this type of factor.
Where you are
Uses one or more authentication methods for access.
Multifactor authentication
An authentication mechanism in which both parties authenticate each other.
Mutual authentication
Elements of a complex password.
Uppercase, lowercase, numbers, and symbols
Unique personal characteristics, such as fingerprints, used for identification purposes.
Biometrics
A stipulation that our chosen biometric characteristic should be present in the majority of people we expect to enroll in the system.
Universality
A measure of the differences of a particular characteristic among a group of individuals.
Uniqueness
How well a particular characteristic resists change over time and with advancing age.
Permenance
How easy it is to acquire a characteristic that we can later use to authenticate a user.
Collectability
A set of metrics that judge how well a given system functions.
Performance measurement
A measure of how agreeable a particular characteristic is to the users of a system.
Acceptability
Describes the ease with which a system can be tricked by a falsified biometric identifier.
Circumvention
The rate at which we accept users whom we should actually have rejected.
FAR
FAR is the rate at which we accept users whom we should actually have rejected. What does FAR stand for?
False acceptance rate
