Portable Hardware Token for Secure Cloud Server Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cloud computing environments face challenges in securely configuring and managing servers located outside their data centers, requiring complex administrative processes and lacking robust security measures for external premises.
Innovation Solution
A multi-step security workflow using a portable hardware device with a dynamically generated token, involving token generation, verification, and periodic re-authentication, to securely incorporate servers into isolated virtual networks within the cloud provider's data plane, enabling secure management and configuration using standardized programmatic interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If servers are configured outside provider network data centers, then service scalability and flexibility are improved, but security risks and management complexity increase
Solution Approach 1:
A portable hardware device acts as an intermediary between the server and the provider network. This device generates and holds security tokens that are required for the server to join isolated virtual networks. The hardware device serves as a physical mediator that enables secure external server integration without requiring the server to be physically located within provider network data centers, thus resolving the contradiction between scalability and security risks
2Reliability
If complex administrative processes are used for external server configuration, then security verification is improved, but operational efficiency and ease of management deteriorate
Solution Approach 1:
The portable hardware device performs self-service functions by automatically generating security tokens and maintaining their association with specific servers. The device autonomously manages the security credentials without requiring manual administrative intervention for each token generation or verification operation. This automates the security verification process while maintaining high security standards, thus resolving the contradiction between reliable security verification and operational efficiency
3Reliability
If multiple security measures are implemented for external servers, then security reliability is improved, but device complexity and administrative burden increase
Solution Approach 1:
The portable hardware device is designed as a universal security solution that combines multiple functions: generating security tokens, storing cryptographic keys, verifying server identities, and managing network authentication. By consolidating these multiple security measures into a single multi-functional device, the system achieves high security reliability while reducing the administrative burden that would result from implementing separate security mechanisms
Data Source
AI summary
A connectivity enablement device includes one or more processors, one or more memories and a hardware input port. The memories store program instructions that when executed examine a token obtained from a token transfer device inserted into the port, and cause one or more messages to be transmitted to a virtualized computing service. The messages indicate (a) the connectivity enablement device, (b) the token transfer device, (c) the token's source and (d) a server. An indication that the server has been configured within an isolated virtual network is obtained at the connectivity enablement device.
