Why Adding an Authorized User to EC2 is Necessary

As a frequent user of Amazon Web Services (AWS) and specifically the Elastic Compute Cloud (EC2) service, I have come to understand the importance of adding authorized users to my instances. In fact, it has become an essential part of my workflow when setting up and managing new instances.

The primary reason for adding authorized users is security. By default, only the root user has complete access to an EC2 instance. However, granting root access to multiple users can be risky as it increases the chances of accidental or intentional misuse of resources. By creating separate user accounts with specific permissions and access levels, I can ensure that only authorized users have access to critical functions and data.

In addition to security concerns, adding authorized users also allows for better collaboration and delegation of tasks within a team or organization. As a project manager, I often need to assign specific tasks or responsibilities to different team members. By creating separate accounts for each team member with relevant permissions, I can effectively manage and track their activities without compromising security.

Moreover, adding authorized users also promotes accountability. Each user account is associated with a unique login ID and password, making it easier to trace any changes made on an instance back to the

My Buying Guide on ‘Add Authorized User To Ec2’

As a frequent user of Amazon Web Services (AWS), I have often found myself in need of adding authorized users to my EC2 instances. This process can be daunting for first-time users, but with the right guidance, it can be done seamlessly. In this buying guide, I will share my experience and provide step-by-step instructions on how to add authorized users to your EC2 instance.

What is an authorized user in EC2?

An authorized user is a person or entity that has been granted access to your EC2 instance. These users can log in and perform various actions on the instance, such as launching new instances, managing security groups, and accessing files. Adding authorized users is essential for collaborative projects or when you need to grant specific permissions to others.

Step-by-Step Guide

Step 1: Create an IAM User

To add an authorized user to your EC2 instance, you first need to create an IAM (Identity and Access Management) user. This user will have its own login credentials and permissions separate from the main AWS account holder. To create an IAM user:

1. Log in to your AWS Management Console.
2. Go to the IAM service under the ‘Security, Identity & Compliance’ section.
3. Click on ‘Users’ from the left-hand menu.
4. Click on ‘Add User.’
5. Enter a name for your new user and select ‘Programmatic access’ as the access type.
6. Click on ‘Next: Permissions.’
7. On the next page, select ‘Attach existing policies directly.’
8. Search for and select the policy named ‘AmazonEC2FullAccess.’
9. Click on ‘Next: Tags’ and then ‘Next: Review.’
10.Carefully review your settings and click on ‘Create User.’

Note: Make sure to save the Access key ID and Secret access key provided during this process as you will need them later.

Step 2: Add the newly created IAM user as a trusted entity

Once you have created the IAM user, you need to add it as a trusted entity for your EC2 instance.

1. Go back to your AWS Management Console and go to the EC2 service.
2. Select your desired instance from the list.
3. Under the Description tab, click on Security groups.
4. Select the security group associated with your instance.
5.Click on Edit inbound rules.
6.Click on Add rule.
7.Select HTTPS from Type dropdown menu and choose Custom from Source dropdown menu.
8.Enter “arn:aws:iam::123456789:user/your_IAM_username” into Custom field (replace 123456789 with your AWS account ID and replace “your_IAM_username” with actual username).
9.Click Save.

Step 3: Configure SSH Authentication

If you use SSH authentication for logging into your EC2 instance, you will also need to configure it for your newly created IAM user.

1.Log into your instance using SSH authentication as usual.
Note down any changes that you make in this process in case something goes wrong.

Create .ssh folder if it does not already exist by executing mkdir ~/.ssh.

Create authorized_keys file by executing touch ~/.ssh/authorized_keys.

Add public key of IAM user by executing cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys.

Change ownership of .ssh folder by executing chown -R ec2-user /home/ec2-user/.ssh.

Note:
•If ec2-user is not used by default replace it with username used while creating Key Pair
•This command updates ownership of all files within .ssh folder
•This command should be executed as root

Step 4: Test Connection

To ensure that everything has been set up correctly, try connecting to your EC2 instance using SSH authentication with the IAM user’s credentials.

If everything works fine, congratulations! You have successfully added an authorized user to your EC2 instance.

In Conclusion

Adding authorized users to an EC2 instance may seem like a complicated process at first glance, but once you have gone through it step-by-step, it becomes much more manageable. With this buying guide at hand, I hope that you can now confidently add authorized users to any of your EC2 instances without any hassle or confusion!
