RSA’s SecurID is an example of which of the following?

A. SSO system

B. Synchronous authentication

C. Token authentication

D. Asynchronous authentication

Solution

B. RSA’s SecurID is an example of synchronous authentication. RSA secureID Devices or tokens use a one time password that uses a clock that synchronous the authenticator to the authentication server during the authentication process. Each individual passcode is valid for only a very short period, normally 60 seconds or less and is used with a user name and password for two factor authentication. Answer A is incorrect because RSA’s SecurID might be part of an SSO system, but this is not an accurate answer. Answer C is incorrect because although the RSA’s SecurID fob itself might be considered a token, it is not the BEST answer available out of the four to choose from. Answer D is incorrect because asynchronous authentication devices are not synchronizedto the authentication server. These devices use a challenge-response mechanism.
