Authentication Methods
Authentication is a process through which requests to access a system, network, or device by a user are identified (Lal, Salendra, and Mohammed, 246). The authentication of users helps make sure that unauthorized users are flagged and kept from accessing sensitive and confidential information. The authentication methods used by organizations differ based on the need to be served, such as access to a premise, or information system. The conventional authentication approaches include password-based authentication, multi-factor authentication, biometric authentication, and out-of-band authentication (Lal et al., 246). The password-based authentication encompasses a string of letters, and special numbers and which is used to manage access to a given information system, or asset, such as a database.
