When setting up a new cloud account, it might seem easiest to use the default root account to manage everything. However, this approach can lead to serious security risks. The root account has full access to all services and settings, so if it's compromised, everything in your cloud environment is at risk.
Instead, the best practice is to create individual, less-privileged user accounts for daily tasks. These accounts should have only the permissions they need to do their jobs. This is where Identity and Access Management (IAM) comes in.
Most cloud platforms, like AWS, Azure, and Google Cloud, come with built-in IAM tools. These tools let administrators create users and assign roles and permissions to control what each account can access or do. Not only can users have identities, but resources like applications or virtual machines can too. This means roles and permissions can be assigned to both people and services.
Once an identity is created, authentication methods such as passwords, multi-factor authentication (MFA), or digital certificates help verify that the person or application trying to access the cloud is who they say they are.
In short, IAM is a crucial part of cloud security. It helps protect your environment by ensuring the right people and tools have the right access.
In this module, we’ll explore how IAM works in cloud computing, how to properly set it up, and why it is one of the most important steps in keeping your data safe.
