Remote Network Device Configuration Audit and Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current central management systems for network devices, such as access points and switches, can ensure that configuration files are up-to-date but fail to validate if the settings are correctly implemented, leading to potential unauthorized access as devices may incorrectly implement configurations, turning secure networks into insecure ones.
Innovation Solution
A method and system that involve a controller transmitting requests to network devices for their configuration status, determining if the implemented status matches the intended configuration, and performing a recovery process to adjust the settings when a mismatch is found, ensuring proper execution and preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If configuration files are remotely transmitted to network devices, then configuration updates are achieved, but implementation correctness cannot be validated
Solution Approach 1:
The system implements a feedback mechanism where the controller receives status information from network devices about their actual configuration implementation state. This feedback loop enables the controller to verify whether the configuration was correctly applied and to detect discrepancies between intended and actual configurations, thereby resolving the reliability issue while maintaining efficient remote configuration updates.
Solution Approach 2:
The system performs preliminary validation by comparing the intended configuration settings against the actual implementation status before considering the configuration process complete. This preliminary check ensures that configurations are not only transmitted but also correctly implemented, preventing security vulnerabilities from undetected configuration failures.
2Device complexity
If configuration implementation is not validated, then system complexity is reduced, but network security is compromised
Solution Approach 1:
The controller receives feedback from network devices regarding their operational status and configuration implementation. This feedback mechanism enables security validation without requiring complex manual verification processes, as the system automatically monitors and reports configuration compliance status from device endpoints.
Solution Approach 2:
Network devices autonomously report their configuration implementation status to the controller without requiring external intervention. This self-service approach allows the system to validate configuration correctness and detect security risks automatically, maintaining network security while avoiding the complexity of manual verification systems.
3Manufacturing precision
If status monitoring is implemented for all configuration settings, then implementation accuracy is improved, but system complexity increases
Solution Approach 1:
The system extracts and monitors only the critical configuration settings and operational status parameters that are essential for security and correct operation. By focusing monitoring efforts on key parameters rather than all possible configuration elements, the system achieves high implementation accuracy for security-critical settings while avoiding the complexity of comprehensive monitoring of every configuration detail.

AI summary
Systems, methods, and computer-readable media are disclosed for remotely managing and correcting implementation of configuration settings at network devices operating in the network. In one aspect of the present disclosure, a method includes transmitting, by a controller, a request to a network device of the network for a status of operation of the network device with respect at least one configuration setting available at the network device; determining, by the controller, whether the status matches an operation status provided by the at least one configuration setting; and performing, by the controller, a recovery process to adjust the implementation of the at least one configuration setting when the determining determines that the status does not match the operation status.
