Open Telekom Cloud for Business Customers

Identity and Access Management (IAM)

The Identity and Access Management (IAM) service provides granular access control for Open Telekom Cloud services. It is an essential service for cloud environments to identify and authorize cloud users.

IAM helps you securely control access to resources by centrally managing user data and authorizations, making it one of the cornerstones for secure working in the cloud.

With IAM, you can define which users are allowed to access which services and resources under which conditions to ensure the least privilege principle.

Reasons for IAM in the Open Telekom Cloud

Security & Compliance

IAM helps you restrict cloud resource access to authorized users and services only. It enables control and monitoring of user access and supports adherence to security policies and compliance regulations.

Scalability

Cloud environments are dynamic and scalable, which means that the number of users and resources can change quickly. IAM makes it possible to quickly add new users or change access rights to support the scalability and agility of the cloud infrastructure.

Cost optimization

IAM is integrated into the Open Telekom Cloud and is free of charge. The management of user and resource access rights prevents costs, e.g., due to excessive authorizations or underutilization of resources. In addition, companies achieve their compliance and security goals, avoiding high costs for security breaches or non-compliance.


Key features of IAM

Access control

Create IAM users and groups and use policies to grant or deny access to specific services and resources. IAM also provides an additional isolation layer: projects. This layer controls user access to different projects and grants permissions within the same project.

Integration

Establish a position of trust between your existing identity system by creating a SAML-based or OpenID Connect-based identity provider. This way, users in your organization can log in to the Open Telekom Cloud via Single Sign-On (SSO).

Delegation

Delegate a trusted Open Telekom Cloud account or cloud service to access your resources based on assigned permissions.

Account Security

With IAM, you can configure security settings, including logon authentication policies, password policies, and access control lists.


Structure and function

IAM manages users and permissions for cloud resources in the Open Telekom Cloud. Cloud resources are services or objects, such as the Key Management Service (KMS) or Object Storage Service (OBS) and associated actions on objects, such as creating a key in KMS or deleting a bucket in OBS.

For the management of authorizations, IAM supports three user types:

  • Agency users are users from other Open Telekom Cloud clients who have been granted access to this client.
  • IAM users are users created and managed in the client's IAM system by the administrators. This is the default user type.
  • Federate users are from third-party IAM systems that can log on to the Open Telekom Cloud via a federation, for example from a federated Active Directory or LDAP.

With the IAM service, you can define who is allowed to access what. For each access request, the set permissions are evaluated and denied by default. Only an explicit "allow" grants access.

Users are assigned to groups which are in turn assigned permissions. Based on the sum of all assigned permission sets / policies, access is evaluated and granted or denied to the users of that user group.

 

IAM policies include actions, resources, and conditions. You can either use the system default policies or create new custom policies using JSON or the graphical editor. 

Access can be set up through the Management Console or the API.

IAM in the Open Telekom Cloud adds an additional isolation layer called projects. Projects can be spanned at the region level (region-based authorization) and serve as isolation to different environments in the same tenant.

The costs of the individual projects are added up on the tenant, so that this can also result in optimized prices (e.g., by jointly achieving higher scales for object storage).
