authentication Flashcards
the initial process of confirming the identity of a users normally done at the user ID to log on
identification
this occurs during the identification phase as the user proves that they are who they say they are in order to obtain credentials
identity proofing
when your identification has been verified, you will be granted ?
authentication
this authentications method, requires that you provide a password
something you know
this authentications method, is based on something a user has in their possession
something they have
this authentications method, uses a biometric system
something you are
this means that all possess a particular attribute
universality
this means that the attribute is different for each individual
uniqueness
this means that the attribute always exists and will not change over time
permanence
this ensures that the attribute can be measured easily
collectability
this means that the attribute can be accurately and quickly collected
performance
this allow for acceptable substitutes for the attribute in the case the original attribute is missing or can’t be read
circumvention
this identifies the degree to which the technology is accepted by users and management
acceptability
this authentications method, is a supplementary authentication factor that uses physical location to verify a uses identity
somewhere you are
this authentications method, is a supplementary authentication factor that requires an action to verify a users identity
something you do
example:
handwriting sample
type test
this occurs when a person who should be allowed access is denied access
false negative.
this occurs when a person who should be denied access is allowed access
false positive
the point at which the number of false positives match the number of false negatives in a biometric system
crossover error rate
the number of subjects or authentication attempts that can be validated
processing rate
the original authentication protocol for Windows computers
LAN Manager (LANMAN)
this authentication protocol supports Window 9 and pre NT systems
LANMAN
this authentication protocol, replaced LANMAN
NT LANMAN
this authentication protocol, is supported by all current window operation systems
NT LANMAN
this authentication protocol, uses both authentication and authorization and is used by computers use an Active Directory domain
Kerberos
Kerberos uses _____ to authenticate users and to authorize resources
security tokens or tickets
Kerberos uses _____ to grant tickets for specific resources
a ticket granting server
what is the function of the Key distribution center (KDC)
combines the authentication server and ticket granting servers
it allows a use to sign on once to a network and access all authorized resource on the network
single sign on (SSO)
this SSO solution is used my Macintosh and Unix
Kerberos
this SSO uses symmetric key cryptography
Kerberos
this SSO solution uses asymmetric cryptography
SESAME
