User Authentication Interview Question 2022

What is Authentication?

The process of user authentication in the context of computer systems means assurance and confirmation of a user’s identity. Before a user attempts to access information stored on a network, he or she must prove their identity and permission to access the data. When logging onto a network , a user must provide unique log-in information including a user name and password, a practice which was designed to protect a network from infiltration by hackers. Authentication has further expanded in recent years to require more personal information of the user, for example, biometrics, to ensure the security of the account and network from those with the technical skills to take advantage of vulnerabilities.

How does Authentication work with security?

User Authentication employs different combinations of data, passcodes, QR codes, passwords, pass cards, digital signatures, fingerprint, retinal, face and voice scans to verify a users’ identity before they can access a network. Proper authentication is often provided through a solution like a secure web gateway and deployment of multiple, cohesive security protections and solutions, like next-generation firewall and endpoint protection.

Authentication leads to Authorization

Authentication now gives allowed users access to systems and applications. But there is more! Once the system knows who users are, policies can be applied that control where the users can go, what the users can do, and what resources they can access. This is called authorization. Authorization is important as it ensures that users cannot have more access to systems and resources then they need. This also makes it possible to identify when someone is trying to access something they should not. For example, only giving medical personnel and not administrative personnel access to patient records, ensuring patient confidentiality.
