Multi-factor authentication (MFA) is a security system that requires verification in multiple stages or more than one phase or multiple credentials. The concept of MFA generally requires additional features other than username and password which might include a code on user smartphone, a security question an application based code, or facial recognition.
Multi-factor Authentication is an effective way to provide enhanced security to its clients. Generally, username and passwords can be compromised and the hackers have found out multiple ways to hack into our accounts through phishing emails as the first and most frequent part of hacks for multiple types of accounts.
How Does Multi-Factor Authentication Works
Multi-Factor Authentication is a layered defense system that makes authorization for an unknown person more difficult to access a particular database, Physical location, network drive, or any kind authentication method which requires username and password for access. Generally, the vendors have named MFA as a scheme that requires more than one authenticity.
Multi-factor Authentication adds up a security platform that needs to be set up as per the application or the program. In this method, once the Multi-Factor Authentication is enabled the additional security needs an application like Google Authentication or DUO. It may also require phone number as we see the One-time Password send to the cell phones for further verification, almost all the credit, debit cards require an SMS verification while doing a transaction online or Offline.
Authentication Factors in MFA
An authentication factor can be the classification of credentials used to verify the authenticity of the user. Every Authentication factor in MFA could increase the chance of the entity has been verified with a communication medium for the access points. Authentication factors are classified into three different categories which are required:
Knowledge factor is a type of knowledge-based authentication that would require the user to provide the answer to a secret question. With every email account or Microsoft account, the security questions are acting as an additional authentication method.
Possession factors are that a user must have some additional security devices, such as a security token, a Key Fob, or a phone’s Sim Card. For smartphone authentication, a smartphone would be the device which provides a possession factor, in coordination with an authentication application.
Inherence factors are any biological traits the user has that are confirmed for login. It might include biometric authentication including the following: Retina Scans, Iris scan, Fingerprint Scans, Hand Geometry, Facial recognition, Voice recognition features.
Location factors depend upon a user’s current location often suggested as the fourth factor for authentication purposes. The operating system of the smartphone can help ease the authentication purpose as most smartphones have a GPS device, enabling reasonable security confirmation of the login location.
Time factors are also sometimes considered a fourth important factor for authentication or replace the fifth factor. Verification of an employee ID against work schedules could prevent attacks from some random hackers. A bank customer can’t physically use their Bank cards in America, for example, and then in Russia 15 minutes later. The kinds of logical locks may help prevent many cases of online banking fraud in the country.
The overall conclusion for Multi-factor Authentication would be the same as compared to an added security feature in any kind of authentication method. Multiple authentications are very important in any kind of fraud that is going on, with the evolution of technology the attacks are being modified and cannot be traced further. Our cyber-security team is working day/night to stop these malicious activities but it’s not only there responsibility to enhance our security features rather we should take some security measures from our end by enabling Multi-factor authentication methods.
