Today, both sides of modern culture are decisively invaded by digitalization. Authentication is considered to be one of the main components in keeping this process secure. Cyber criminals are working hard in penetrating through the existing network channels to encounter malicious attacks. When it comes to enterprises, the company's information is a major asset. Question here arises is how to protect the vital information. This takes into account various aspects of a society often termed as hyper connected society including online communication, purchases, regulation of access rights and many more. In this research paper, we will discuss about the concepts of MFA and KBA, i.e., Multi-Factor Authentication and Knowledge Based Authentication. The purpose of MFA and KBA its utilization for human.to.everything..interactions, offering easy to be used and secured validation mechanism while having access to the service. In the research, we will also explore the existing yet evolving factor providers (sensors) used for authenticating a user. This is an important tool to protect data from malicious insiders and outsiders. Access Management main goal is to provide authorized users the right to use a service also preventing access to illegal users. Multiple techniques can be implemented to ensure access management. In this paper, we will discuss various techniques to ensure access management suitable for enterprises, primarily focusing/restricting our discussion to multifactor authentication. We will also highlight the role of knowledge-based authentication in multi factor authentication and how it can make enterprises data more secure from Cyber Attack. Lastly, we will also discuss about the future of MFA and KBA.

In this paper, a zero trust-based complex biometric authentication was proposed in a passwordless environment. The linkage of FIDO 2.0 (Fast IDENTITY Online) transaction authentication platforms was designed in conjunction with metaverse. In particular, it was applied with the location information of a smart terminal according to a geomagnetic sensor, an accelerator sensor, and biometric information for multi-factor authentication(MFA). At this time, a FIDO transaction authentication platform was presented for adaptive complex authentication with user's environment through complex authentication with secondary authentication based on situational awareness such as illuminance and temperature/humidity. As a result, it is possible to authenticate secondary users based on zero trust with behavior patterns such as fingerprint recognition, iris recognition, face recognition, and voice according to the environment. In addition, it is intended to check the linkage result of the FIDO platform for complex integrated authentication and improve the authentication accuracy of the linkage platform for transaction authentication using FIDO2.0.

COVID-19 팬데믹으로 인하여, 재택근무와 같은 비대면 업무환경이 확대됨에 따라, 기업에서는 내부 보안을 위한 VPN 구축 및 사용률이 급격하게 증가하였다. 하지만, 기존의 대면 환경과는 다르게, 비대면 업무환경에서는 자신을 식별할 수 있는 수단을 제한적으로 활용하기 때문에, 사용자의 비밀번호가 노출되면, VPN에 접근하기 위한 사용자 인증이 무력화되는 심각한 문제점이 존재하며, 이러한 보안 취약점을 해결하기 위한 기술이 요구되는 실정이다. 따라서 본 논문에서는 기존 VPN 인증 기술에 내재된 보안 취약점을 해결하기 위하여, 사물 환경 인증, HIP 기술, 위치 인증, 상호 인증 기술을 활용한 다중 인증 기반의 제로 트러스트를 제공하는 VPN 인증 기술을 제안한다. 최종적으로는 본 논문에서 제안하는 기술을 통하여, 보다 안전성이 향상된 VPN을 제공할 것으로 사료된다.
