What are the different types of IAM roles in Cloud Computing?

In Cloud Computing, Identity and Access Management (IAM) roles play a crucial role in defining permissions. Three primary types are: 1)User-Based Roles: Assigned to individuals, granting specific access. Example: AWS IAM user with permissions to manage S3 buckets. 2)Resource-Based Roles: Tied to specific resources, defining access for entities outside the resource. Example: AWS Lambda execution role specifying permissions for a function. 3)Service-Based Roles: Allocated to services or applications, allowing them to interact with other services. Example: Google Cloud Service Account with roles for accessing Google Cloud Storage. IAM roles provide granular control over cloud resources, enhancing security and governance.

Basic IAM roles typically include the following: The "Owner" role has full access to resources, enabling complete control. The "Administrator" role focuses on managing resources but doesn't grant billing permissions. The "Editor" role allows users to modify and create resources but excludes managing permissions. The "Viewer" role provides read-only access to resources without the ability to make changes. These roles ensure a structured approach to access control, enabling organizations to tailor permissions based on user responsibilities and requirements. IAM roles play a fundamental role in maintaining security and governance within cloud environments by clearly defining and restricting access to resources.

In cloud computing, fundamental IAM (Identity and Access Management) roles include: 1. Administrator: Full access to all resources. 2. User: Standard role with defined permissions. 3. Read-Only: Limited to viewing resources. 4. Power User: Like an administrator with restrictions. 5. Security Auditor: Focuses on monitoring and auditing for security compliance. These roles establish a baseline for managing access and permissions, ensuring a structured and secure approach to user interactions within a cloud environment.

Custom IAM roles in Cloud services for example in GCP allows to define precise sets of permissions tailored to an organisation’s specific needs. A user might not need all the permissions that is added in the predefined roles. Custom IAM roles provide a flexible and tailored approach to access control, enhancing security by precisely defining permissions and adhering to the principle of least privilege.

Custom IAM (Identity and Access Management) roles allow organizations to tailor permissions for specific needs. These roles are created based on unique requirements, defining granular access controls. For example, a "Data Analyst" role might have read access to specific databases. Custom roles enhance security by ensuring precise access, aligning permissions with specific job functions or project requirements within a cloud environment.

Service-linked IAM roles are pre-defined roles created and managed by cloud services. They facilitate secure interactions between services and resources, having predefined permissions tailored for specific service needs. Users typically cannot directly modify these roles, ensuring the integrity and security of service interactions within various cloud environments.

Federated IAM (Identity and Access Management) roles involve establishing trust between an identity provider (IdP) and a service provider. Users authenticated by the IdP can assume federated roles in the service provider's environment. This enables cross-platform access without the need for separate credentials. Federated IAM roles enhance security and streamline access management, allowing organizations to leverage external identity providers for seamless and controlled user access within cloud environments.

Delegated IAM (Identity and Access Management) roles involve assigning specific permissions to users or entities, granting them limited authority over certain resources. This delegation allows for distributed access management without providing full administrative privileges. Delegated roles empower individuals or systems with the necessary permissions to perform specific tasks, fostering a more granular and secure approach to access control within a cloud environment.
