Channel Card Command Translation for Secure Nonstandard Feature Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing interactions between aftermarket hardware components and stock hardware components in data processing systems poses security risks and disrupts computer-implemented services due to the inability of stock hardware components to natively invoke non-standard features of aftermarket components, which can be compromised by third-party software updates.
Innovation Solution
Incorporating an out-of-band management controller to manage third-party software for aftermarket components, using secure communication channels to obtain and translate commands for non-standard features, thereby facilitating their use while reducing security risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If third-party software is used to manage aftermarket components, then nonstandard features can be utilized, but security risks and system compromise increase
Solution Approach 1:
The system is divided into two separate environments: a secure out-of-band management environment and a standard in-band operational environment. The management controller operates in the secure out-of-band environment to handle third-party software and commands, while the host system operates in the in-band environment. This segmentation isolates security risks to the management domain, preventing compromise of the main system while still enabling nonstandard features through controlled command translation.
Solution Approach 2:
The management controller acts as an intermediary between the host system and aftermarket components. It receives commands from the host, screens them using third-party software in the secure out-of-band environment, translates nonstandard commands into standard commands, and executes them through standard interfaces. This intermediary role enables nonstandard feature usage while maintaining security by preventing direct third-party software access to the host system.
2Adaptability or versatility
If third-party software updates are applied to host system, then functionality is improved, but system stability and security are compromised
Solution Approach 1:
Software updates and third-party software are confined to the out-of-band management environment rather than being applied to the host system. The management controller runs third-party software in this isolated environment to screen and translate commands, while the host system maintains its stable, unmodified state. This segmentation allows functionality updates in the management domain without compromising host system stability.
Solution Approach 2:
The management controller creates a copy of the command processing functionality in the secure out-of-band environment. Instead of modifying the host system with third-party software, the management controller implements command screening and translation logic that replicates the necessary functionality in an isolated environment, allowing updates without affecting host system reliability.
3Adaptability or versatility
If aftermarket components with nonstandard features are used, then system capability is enhanced, but compatibility and reliability decrease
Solution Approach 1:
The management controller serves as an intermediary that bridges aftermarket components with nonstandard features and the host system with standard interfaces. It screens commands using third-party software, translates nonstandard commands into standard commands that the host system can reliably execute, and manages the interaction between incompatible components. This ensures enhanced capability through aftermarket components while maintaining operational reliability through standardized host system interfaces.
Solution Approach 2:
The system changes the parameter space of command execution by introducing a translation layer. Nonstandard commands with extended parameter sets are transformed into standard commands with standardized parameter sets that the host system can reliably process. This parameter transformation allows aftermarket components to operate with enhanced capabilities while the host system maintains its established reliability characteristics.
Data Source
AI summary
Methods and systems for managing operation of a data processing system are disclosed. Hardware resources of the data processing system may issue a command for execution by a channel card of the data processing system. The channel card may be manufactured by a vendor different to a manufacturer of the data processing system. A management controller of the data processing system may identify and screen the command based on vendor software for the channel card (e.g., proprietary software of the vendor). The vendor software may be usable to facilitate use of a non-standard feature of the channel card. When the vendor software indicates that the command implicates use of the non-standard feature, the command may be modified by the management controller. The modified command may be used to initiate execution of the non-standard feature by the channel card to facilitate provisioning of a computer-implemented service.
