With these new applications being created over the cloud, mobile and on-premise can hold sensitive and regulated information. It’s no longer acceptable and feasible to just create an Identity server and provide access based on the requests. In current times an organization should be able to track the flow of information and provide least privileged access as and when required, obviously with a large workforce and new applications being added every day it becomes quite difficult to do the same. So organizations specifically concentrate on managing identity and its access with the help of a few IAM tools. It’s quite obvious that it is very difficult for a single tool to manage everything but there are multiple IAM tools in the market that help the organizations with any of the few services given below.
IAM Identities Classified As
- IAM Users
- IAM Groups
- IAM Roles
Root user
The root user will automatically be created and granted unrestricted rights. We can create an admin user with fewer powers to control the entire Amazon account.
IAM Users
We can utilize IAM users to access the AWS Console and their administrative permissions differ from those of the Root user and if we can keep track of their login information.
Example
With the aid of IAM users, we can accomplish our goal of giving a specific person access to every service available in the Amazon dashboard with only a limited set of permissions, such as read-only access. Let’s say user-1 is a user that I want to have read-only access to the EC2 instance and no additional permissions, such as create, delete, or update. By creating an IAM user and attaching user-1 to that IAM user, we may allow the user access to the EC2 instance with the required permissions.
IAM Groups
A group is a collection of users, and a single person can be a member of several groups. With the aid of groups, we can manage permissions for many users quickly and efficiently.
Example
Consider two users named user-1 and user-2. If we want to grant user-1 specific permissions, such as the ability to delete, create, and update the auto-calling group only, and if we want to grant user-2 all the necessary permissions to maintain the auto-scaling group as well as the ability to maintain EC2,S3 we can create groups and add this user to them. If a new user is added, we can add that user to the required group with the necessary permissions.
Identity and Access Management
In a recent study by Verizon, 63% of the confirmed data breaches are due to either weak, stolen, or default passwords used. There is a saying in the cybersecurity world that goes like this “No matter how good your chain is it’s only as strong as your weakest link.” and exactly hackers use the weakest links in the organization to infiltrate. They usually use phishing attacks to infiltrate an organization and if they get at least one person to fall for it, it’s a serious turn of events from thereon. They use the stolen credentials to plant back doors, install malware or exfiltrate confidential data, all of which will cause serious losses for an organization.
