How can it achieve this?
Create an IAM policy with the security group and use that security group for AWS console login
Create an IAM policy with a condition which denies access when the IP address range is not from the organization
Configure the EC2 instance security group which allows traffic only from the organization’s IP range
Create an IAM policy with VPC and allow a secure gateway between the organization and AWS Console
Explanations:
Security groups are used for controlling traffic to and from EC2 instances, not for restricting IAM user access to the AWS Console.
An IAM policy with a condition that restricts access based on the user’s IP address can ensure that only users within the organization’s IP range can access the AWS Console.
EC2 instance security groups control inbound and outbound traffic for EC2 instances but do not affect IAM user access to the AWS Console.
VPC and secure gateways are used for controlling network traffic within a VPC, but they are not relevant for restricting IAM user console access.
From my perspective, the answer is:
Create an IAM policy with a condition which denies access when the IP address range is not from the organization
