example 1

[0126] Example 1 is a machine in a multi-tenant computing system, including:

[0127] A collection of local policies that map commands to isolation levels in a multi-tenant computing system;

[0128] an authentication worker component that receives a workflow from a remote user identifying a request command to be executed on the machine using the remote management client system, accesses the local policy to identify a corresponding isolation level, and Execute commands in the execution environment of the isolation level; and

[0129] A processor activated by an authentication worker component and facilitating accessing said local policy and executing said commands.

example 2

[0130] Example 2 is a machine in any or all of the previous examples in a multi-tenant computing environment, where the authentication worker component includes:

[0131] An isolation level identifier component that, based on the requested command, accesses the set of local policies to identify a corresponding isolation level that maps to the requested command.

example 3

[0132] Example 3 is a machine in any or all of the previous examples in a multi-tenant computing environment, where the authentication worker component includes:

[0133] an execution environment generator that receives the identified isolation level and generates an execution environment with the identified isolation level on the machine.

Abstract

When a user inputs an action request, such as a requested command, to be performed on a target machine, a management system receives the request and verifies it with a separate authentication and permission system. The verified command request is sent to the target machine. An authentication worker on the target machine accesses a set of policies, local to the target machine, to identify a least privileged execution environment in which the requested command can be performed. The authentication worker on the target machine launches the requested command within the identified least privileged execution environment on the target machine.

Description

Background technique [0001] Computer systems are currently in widespread use. Some such computer systems are deployed in multi-tenant environments, where a multi-tenant service provides services to multiple different tenants. Each tenant can correspond to a separate organization. [0002] The level of service provided by a multi-tenant system can vary widely. For example, they can range from Infrastructure as a Service (IaaS), where items of the infrastructure are managed by the service provider and all other items are managed by individual tenants, to Software as a Service (SaaS), where Even the applications used by the tenants are run and managed by the service provider. [0003] Such systems may present difficulties regarding security. Every organization served by a service provider expects the service provider to have sufficient access to the organization's data to enable the service provider to provide adequate services. However, the organization also wishes to provi...
