You may be asked for different aws terms, so we have included some basic concept as under

What is IAM?

IAM mean Identity, Access and Management. It’s a service that lets you manage access to AWS resources. IAM allows you to create groups and users and grant them permissions. IAM also lets you create roles and give them to users or groups. Roles are like permissions, but anyone with the role’s ARN can assume them. IAM is a critical part of security in AWS because it helps you control who has access to your AWS resources and what they can do with them.

AWS Security

What is MFA?

MFA is a stand for Multi-Factor authentication. It is a security protection that enables more than one type of authentication to gain access to an system. For example, you might use a password and a code from an authenticator app. MFA adds an extra layer of security to your AWS account by making it more difficult for unauthorized people to gain access. With this extra security method you can request a OPT code on email or on mobile number to access the AWS resource.

What is encryption?

The transformation of data is done by encryption so that those with the right key have the ability to only access it. Encryption is utilized to safeguard data during the process of transport and in rest. In transit, data is encrypted while transmitted from one location to another. Encryption is a critical part of security in AWS because it helps protect your data from being accessed by unauthorized people. AWS provide bydefault encryption on different services, but you can also enable the encryption using different services.
