Not always. Authentication is based upon one or more of the following:
An ID card portrays authentication based upon something the user has.
Authentication is based upon either:Something you know (such as a PIN).Something you have (such as an ID card).Something you are (such as a fingerprint, retina scan or DNA sample).Preferably, authentication will combine two or more of the three.
Not always. Authentication is based upon one or more of the following:Something the user knows (such as a PIN).Something the user has (such as an ID card).Something the user is (such as a fingerprint).
Yes. Any biometric reading, such as a fingerprint, retina scan or DNA sample portrays authentication based upon something the user is.
Yes.
Authentication based on "something that is" refers to biometric authentication, which verifies an individual's identity through unique physical traits. This includes methods such as fingerprint scanning, facial recognition, and iris scanning. Biometric systems rely on the inherent characteristics of a person, making them difficult to replicate or steal, enhancing security in various applications like smartphones and secure access systems.
Three common ways to authenticate someone are: Knowledge-based authentication: This involves something the user knows, such as a password or PIN. Possession-based authentication: This requires something the user has, like a security token, smart card, or mobile device for SMS verification. Biometric authentication: This uses unique biological traits, such as fingerprints, facial recognition, or iris scans, to verify a person's identity.
RADIUS requires port-based authentication.
Two-factor authentication uses something a user has in conjunction with something a user knows.
Authentication is something that verifies what is real or true.
Yes, RADIUS requires port-based authentication.
Three factor authentication is based upon three aspects: something you have, something you know and something you are. For instance, you might be asked to present an ID card (something you have), enter a PIN (something you know) and provide a fingerprint (something you are). The latter is a biometric and may include a retina scan or a DNA sample.
