Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
New energy centralized control station networks face significant network security challenges, including hacker attacks and malicious software infections, which can lead to system paralysis and safety risks. Traditional static defense methods are inadequate in addressing internal threats and changing network environments, and the use of fixed IP addresses makes these systems vulnerable to targeted attacks.
Innovation Solution
A dynamic defense system and method for new energy centralized control station networks based on dynamic IP addresses. This system involves acquiring network parameters, constructing an IP address mapping table, monitoring network traffic, evaluating defense states, and dynamically adjusting IP addresses and firewall rules to resist malicious reconnaissance and attacks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional static defense means (firewall, IDS) are used, then external attacks can be prevented to a certain extent, but adaptability to internal threats and changing network environments is poor
Solution Approach 1:
The patent implements dynamic IP address allocation and dynamic firewall rules that automatically adjust based on network traffic analysis. The system transitions from static defense configurations to dynamic ones where IP addresses and firewall rules can change in real-time according to detected threats and network conditions, thereby improving adaptability while maintaining reliability
Solution Approach 2:
The system dynamically changes network parameters including IP addresses, port assignments, and firewall rule sets based on analyzed network traffic patterns and threat detection results. This parameter dynamicization allows the defense system to adapt to evolving threats while maintaining effective protection
2Ease of manufacture
If a fixed IP address is adopted, then network configuration is simple, but it is easier for attackers to find targets and carry out targeted attacks
Solution Approach 1:
The patent implements dynamic IP address allocation where the centralized control station's IP address changes periodically or based on security conditions. This dynamic IP mechanism maintains configuration simplicity through automated management while significantly reducing vulnerability to targeted attacks by making the target location unpredictable
Solution Approach 2:
The system performs preliminary anti-action by proactively changing IP addresses before attackers can identify and target the system. The dynamic IP mechanism preemptively counteracts potential targeted attacks by ensuring the target address is not static or predictable
3Object-affected harmful factors
If dynamic IP adjustment is implemented, then malicious network reconnaissance can be resisted, but system complexity increases
Solution Approach 1:
The system implements self-service through automated IP address management and dynamic firewall rule generation. The centralized control station automatically performs IP allocation, traffic analysis, threat detection, and rule updates without requiring manual intervention, thereby resisting malicious reconnaissance while managing system complexity through automation
Solution Approach 2:
The system uses feedback mechanisms where network traffic is continuously monitored and analyzed, and the results feed back into automatic IP address and firewall rule adjustments. This closed-loop feedback system enables effective resistance to reconnaissance attacks while managing complexity through automated decision-making based on observed network conditions
