What are the Authentication methods in Information Security?

There are various method of Authentication which are as follows −

Biometrics − Biometrics is a term that defines the measuring unique individual characteristics including the retina, the iris, fingerprints or even the face. Today, the concept is usually used by most people to define a method for protecting computers and saved data requiring a user to endure a scan of the body part used for identification.

While several systems need a fingerprint or retinal scan as a user password, systems that are serious about security frequently need a password and a biometric scan before open the computer or device.

There are some common biometric authentication methods include fingerprint identification, voice identification, retinal and iris scans, and face scanning and identification.

Token authentication − A protocol that enables users to check themselves and receive a token in return. They can access the website or app considering that token is true. This system operates like a stamped ticket and it simplifies the verification process for users that have to access the similar app, webpage, or resource, several times.

Multi-factor authentication − It is a security procedure that needed users to respond to requests to check their identities before they can access networks or other online software. MFA can use information, control of physical elements, or geographic or network areas to verify identity.

In Multi-factor authentication, it is an approach to protecting information and applications where a system needed a user to present a set of two or more credentials to check a user’s identification for login.

The protection that MFA adds enables us to use the passwords for a more length of time between password resets, and in the happening that the service provider is negotiated and the email and password end up in an open database on the open web, it will have time to change the password before the single account is negotiated.

Out-of-Band Authentication (OOB) − A definite type of MFA, OOB uses totally independent channels, such as mobile devices, to authenticate transactions that introduced on a computer.

Any transaction that needed deposits from one area to another, like a huge money transfer, can create a phone call, text or notification on an app that there is more authentication needed for the transaction to be done. With two important channels, it is complex for a hacker to steal money.

Certificate-based authentication − This form of authentication need a digital certificate to recognize a user before accessing a resource. It can use this solution for all endpoints such as users, devices, machines, etc.

This is what creates this form of authentication unique. Most of the certificate-based authentication solutions appear with cloud-based administration platforms that create it simpler for administrators to manage, monitor and issue the new authentication for their employees.
