Protocol Setting System for Dynamic Security Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication networks where both secure and unsecured protocols coexist, existing systems face difficulties in ensuring secure communication due to the potential use of legacy protocols, which can compromise security even when secure protocols are enabled.
Innovation Solution
An information processing apparatus equipped with a storage device containing a security list and a protocol setting system that detects and invalidates unsecured communication protocols, ensuring secure communication by managing protocol validity and security levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communication protocols are supported for versatility, then adaptability is improved, but security is worsened due to legacy protocols creating security holes
Solution Approach 1:
The system dynamically changes the validity parameter of communication protocols based on security levels. When a secure protocol is validated, the system automatically invalidates protocols with lower security levels, transforming the static protocol support into a dynamic security-aware configuration
Solution Approach 2:
The protocol setting system continuously monitors the validity status of communication protocols and provides feedback to automatically adjust the validity of other protocols. When secure protocol validation status changes, the system responds by adjusting legacy protocol validity accordingly
2Reliability
If secure communication protocols are enabled, then security is improved, but legacy protocols continue to operate and create security vulnerabilities
Solution Approach 1:
The system preemptively invalidates legacy protocols before they can be used to create security vulnerabilities. By automatically detecting when secure protocols are validated and proactively disabling incompatible legacy protocols, the system prevents potential security holes rather than reacting to them
Solution Approach 2:
The system extracts and removes legacy protocols from the active communication protocol set when secure protocols are validated. This separation ensures that only protocols meeting the required security level remain operational, eliminating the coexistence of secure and insecure protocols
3Extent of automation
If automatic protocol validation is implemented, then security management is improved, but system complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-defining security levels for different communication protocols and establishing validation rules in advance. This preparation allows the automatic protocol setting to function with simpler runtime logic, as the decision-making framework is already established

AI summary
An information processing apparatus, including a storage device a security list, wherein a security level of each of communication protocols installed in a network is listed, a status management list, which describes validity of each communication protocol, and a protocol setting system, which sets validity of each communication protocol, is provided. The protocol setting system includes a status detecting unit, which refers to the status management list and detects validity of each communication protocol, an unsecured protocol detecting unit, which refers to the security list when at least one of the communication protocols is validated and detects a communication protocol with a security level being lower than the validated communication protocol, and a status updating unit, which invalidates the communication protocol detected by the unsecured protocol detecting unit to have the lower security level and detected to be valid by the status detecting unit.
