What will be an ideal response?
Authentication is the process by which a control establishes whether a user (or system) has the identity it claims to have. Examples include the use of cryptographic certificates to establish Secure Sockets Layer (SSL) connections as well as the use of cryptographic hardware devices-for example, hardware tokens such as RSA's SecurID. Individual users may disclose a personal identification number (PIN) or a password to authenticate their identities to a computer system.
