Solution Overview

Problem

Current systems for communicating with service processors in data centers face security breaches due to default user configurations, complex user account management, and the need for local user databases, which also increase storage and management costs and complexity.

Innovation Solution

The system reverses the role of the service processor from a server to a client, using it to discover and establish secure connections with a management console, eliminating the need for local user accounts and using X.509 certificates for authentication, thus reducing security risks and simplifying user account management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a service processor uses pre-configured default user accounts for initial network configuration, then ease of initial setup is improved, but security is worsened due to known default credentials that can be exploited by hackers

Engineering Contradiction:
Improveinitial setupVSAvoidsecurity breaches
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent inverts the traditional authentication model where the service processor acts as a server. Instead, the service processor becomes a client that initiates connections to a management console, which then authenticates the service processor. This reversal eliminates the need for pre-configured default user accounts on the service processor while maintaining ease of initial setup through automated discovery and connection establishment.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent extracts the authentication functionality from the service processor and relocates it to the management console. The service processor no longer maintains local user accounts or performs authentication; instead, it presents credentials to the management console which handles all authentication logic. This extraction eliminates security vulnerabilities associated with local user databases while preserving operational capabilities.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If a service processor maintains a local user account database, then authentication capability is improved, but device complexity and storage requirements are worsened

Engineering Contradiction:
Improveauthentication capabilityVSAvoiduser account management
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the user account database and authentication logic from the service processor and relocates them to the management console. The service processor becomes a thin client that only needs to store minimal credentials for presenting to the management console, eliminating the complexity of maintaining local user accounts, password policies, and authentication mechanisms on resource-constrained devices.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The management console serves as a universal authentication authority for multiple service processors across the network. Instead of each service processor maintaining its own user account database, a single centralized management console provides authentication services to all service processors, reducing overall system complexity and storage requirements while improving security through centralized control.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If a service processor acts as a server listening for client connections, then ease of client connection is improved, but security is worsened due to exposed service ports that require firewall openings

Engineering Contradiction:
Improveclient connectionVSAvoidfirewall security risks
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent inverts the connection initiation model: instead of the service processor acting as a server listening for incoming client connections, the service processor acts as a client that actively initiates connections to the management console. This reversal eliminates the need for external clients to open firewall ports or traverse network security boundaries, as connections originate from within the trusted network zone.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent implements preliminary anti-action by having the service processor establish secure connections to the management console before any external access is attempted. The service processor proactively authenticates itself and establishes encrypted communication channels, preventing external attackers from exploiting open service ports or conducting unauthorized access attempts.

Inventive Principle:
Principle #9Preliminary anti-action

AI summary

The present disclosure relates to a method for using a service processor to communicate with a remote component. The method may involve using the service processor of the device to discover a remote component connected to the device by a network. Once the remote component is discovered, the method may further involve using the service processor to establish a communications channel, using the network, with the remote device. The method may also involve using the service processor of the device to authenticate the remote component.
