Credential Management Locking for Network Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large-scale telecom networks, frequent changes to credential information for security purposes can interrupt maintenance operations, leading to increased maintenance time and network outage time.
Innovation Solution
A credential management apparatus and method that periodically changes credential information and acquires maintenance operation information to lock the credential information of target components during maintenance, preventing changes and minimizing disruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If credential information is periodically changed to enhance security, then security is improved, but maintenance operation time increases
Solution Approach 1:
The system performs preliminary actions by notifying maintenance management apparatuses of scheduled credential changes in advance. This allows maintenance operations to be planned around credential change times, preventing interruptions and reducing overall maintenance time while maintaining security through periodic changes.
Solution Approach 2:
The system dynamically adjusts credential management based on maintenance schedules. The credential management apparatus coordinates with maintenance management apparatuses to temporarily suspend or delay credential changes during active maintenance operations, creating a flexible system that adapts to operational needs while maintaining security protocols.
2Reliability
If credential information is changed during maintenance operation, then security is improved, but maintenance operation is interrupted
Solution Approach 1:
The system sends notifications of scheduled credential changes to maintenance management apparatuses before the changes occur. This preliminary action allows maintenance teams to complete operations before credential changes or pause safely, preventing interruptions while maintaining the security benefit of periodic credential changes.
Solution Approach 2:
The maintenance management apparatuses provide feedback about ongoing maintenance operations to the credential management apparatus. This feedback mechanism allows the system to detect when maintenance is in progress and adjust credential change timing accordingly, preventing interruptions and improving operational efficiency while maintaining security.
3Reliability
If credential information is frequently changed, then security is enhanced, but network outage time increases
Solution Approach 1:
By notifying maintenance management apparatuses in advance of scheduled credential changes, the system enables proactive planning. Network maintenance can be scheduled to complete before credential changes occur, or credential changes can be coordinated to minimize impact on network availability, thereby reducing overall network outage time while maintaining frequent credential rotation for security.
Solution Approach 2:
The system dynamically coordinates credential changes with network maintenance schedules. The credential management apparatus receives feedback about maintenance status and adjusts credential change timing to avoid conflicts, enabling frequent security updates without proportionally increasing network outage time.

AI summary
A credential management apparatus performs a change process, an acquisition process, and a locking process. The change process is processing that periodically changes credential information of components that constitute a network. The acquisition process is processing that acquires maintenance operation information related to a maintenance operation of the network. The locking process is processing that locks the credential information of, among the components, a target component for the maintenance operation not to be changed based on the maintenance operation information, at least during the period while the maintenance operation is being performed.
