Telecommunications Network Command Validation for Secure Device Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telecommunication networks lack robust security measures to validate and authenticate commands before execution, leading to potential unauthorized or mistaken configurations that can disrupt network operations.
Innovation Solution
A network device security system that accumulates and verifies commands by comparing them against authorized and unauthorized command lists, ensuring only valid commands are executed while logging and alerting on unauthorized attempts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If command validation and authentication mechanisms are implemented, then network security is improved, but system complexity increases
Solution Approach 1:
The system performs preliminary validation of commands against authorized lists before execution, accumulating and verifying commands in advance. This prevents unauthorized commands from being executed while maintaining a structured approach to security validation.
Solution Approach 2:
The patent introduces an intermediary validation layer between command input and execution. This intermediary system accumulates commands, validates them against authorized and unauthorized lists, and only permits execution of validated commands, thereby securing the system without requiring fundamental changes to the core network infrastructure.
2Reliability
If comprehensive command verification is performed, then unauthorized commands are prevented, but processing time increases
Solution Approach 1:
Commands are accumulated and validated in advance before execution. The system prepares validation lists and performs verification steps prior to command implementation, ensuring thorough checking without delaying actual execution once validation is complete.
Solution Approach 2:
The validation system uses pre-configured authorized and unauthorized command lists that automatically check commands without requiring manual review. The system serves itself by maintaining and comparing against these lists, reducing the time required for each individual command verification.
3Stability of the object's composition
If strict command authorization control is implemented, then network stability is improved, but operational flexibility decreases
Solution Approach 1:
The system applies different authorization levels and validation rules to different commands and users based on their credentials and the specific network device. This localized approach allows critical commands to have strict validation while permitting less critical operations with reduced overhead, maintaining both stability and flexibility.
Solution Approach 2:
The authorization system dynamically adjusts validation requirements based on user credentials, device type, and command characteristics. The system can adapt its strictness level depending on the context, allowing operational flexibility within the framework of network stability requirements.

AI summary
A secure network device management system and method include monitoring and validating commands to network devices before such commands are executed. The security system accumulates inputs from a network device intended for display on a terminal and provided by the network device in response to inputs from the terminal and received by the network device. When a control input to execute the command is received from the terminal, the security system reproduces the command from the accumulated inputs and compares the reproduced command to a command list to determine whether the command is authorized. If so, the security system provides the control input to the network device such that the network device executes the command. Otherwise, the security system may delete the command and transmit an alert to the terminal.
