Permissions Management

Description

If you need to assign different permissions to employees in your enterprise to access your LTS resources, is a good choice for fine-grained permissions management. IAM provides identity authentication, permissions management, and access control, helping you secure access to your LTS resources.

With IAM, you can use your account to create IAM users for your employees, and assign permissions to the users to control their access to LTS resources. For example, some software developers in your enterprise need to use LTS resources but should not delete them or perform other high-risk operations. In this case, you can create IAM users for the software developers and grant them only the permissions required.

If your account does not need individual IAM users for permissions management, you may skip over this section.

IAM can be used for free. You pay only for the resources in your account. For more information about IAM, see IAM Service Overview.

LTS Permissions

By default, new IAM users do not have permissions assigned. You need to add users to one or more groups, and attach permissions policies or roles to these groups. Users inherit permissions from the groups to which they are added and can perform specified operations on cloud services based on the permissions.

LTS is a project-level service deployed and accessed in specific physical regions. To assign LTS permissions to a user group, specify the scope as region-specific projects and select projects for the permissions to take effect. If All projects is selected, the permissions will take effect for the user group in all region-specific projects. When accessing LTS, the users need to switch to a region where they have been authorized to use LTS.

Policies: A type of fine-grained authorization mechanism that defines permissions required to perform operations on specific cloud resources under certain conditions. This mechanism allows for more flexible policy-based authorization, meeting requirements for secure access control. For example, you can grant Elastic Cloud Server (ECS) users only the permissions for managing a certain type of ECSs. Most policies define permissions based on APIs.

The system permissions supported by LTS are listed in Table 1.

**Table 1** LTS system permissions
Name	Description	Type	Dependency
LTS FullAccess	Full permissions for LTS. Users with these permissions can perform operations on LTS.	System-defined policy	CCE Administrator, OBS Administrator, and AOM FullAccess
LTS ReadOnlyAccess	Read-only permissions for LTS. Users with these permissions can only view LTS data.	System-defined policy	CCE Administrator, OBS Administrator, and AOM FullAccess

Table 2 lists the common operations supported by each system-defined policy and role of LTS. Choose the appropriate policies and roles according to this table.

To use a custom fine-grained policy, log in to IAM as the administrator and select fine-grained permissions of LTS as required.
