Communication Control Apparatus for Zombie Node Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems lack the ability to detect and control nodes operating as 'zombies' or 'springboards' in cyber-attacks, where unauthorized access allows other nodes to be compromised for malicious activities.
Innovation Solution
A communication system with a control instruction apparatus that manages communication history between nodes, determines the state of nodes, and prohibits new communication from nodes acting as servers or clients to prevent them from being used as zombies or springboards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If communication systems allow nodes to establish connections freely, then communication flexibility and connectivity are improved, but security deteriorates as zombies or springboards can operate unnoticed
Solution Approach 1:
The control instruction apparatus performs preliminary actions by managing communication history and determining node states before allowing new connections. It proactively identifies nodes that have established connections (service-providing nodes) and preemptively prohibits new communication attempts from these nodes, preventing zombie or springboard behavior before it can cause harm.
Solution Approach 2:
The system implements feedback mechanisms where the control instruction apparatus continuously monitors communication history to determine node states. Based on this feedback, it dynamically adjusts communication permissions - allowing connections from nodes without established connections while prohibiting connections from service-providing nodes, thus adapting security policies to current network conditions.
2Object-affected harmful factors
If the system monitors and controls node behavior to prevent zombies, then security is improved, but device complexity increases due to communication history management and node state determination
Solution Approach 1:
The control instruction apparatus performs multiple functions within a single integrated system: it manages communication history, determines node states (client/server identification), and controls communication permissions. This multi-functional approach consolidates what could be separate complex components into one unified apparatus, reducing overall system complexity while maintaining security capabilities.
Solution Approach 2:
The control instruction apparatus autonomously manages security control by self-determining node states based on communication history without requiring external intervention. The system serves itself by automatically identifying service-providing nodes and applying appropriate access control policies, eliminating the need for complex external monitoring or manual configuration.
3Object-affected harmful factors
If access control is implemented to prevent unauthorized access, then security is improved, but ease of operation deteriorates as nodes cannot initiate new connections once they become service-providing
Solution Approach 1:
The access control policy applies different quality levels of connectivity to different node types. Service-providing nodes (clients) are granted local quality - they can initiate connections but are prohibited from receiving new connections. Non-service-providing nodes maintain full connectivity quality. This differentiated approach maintains operational flexibility for legitimate clients while preventing zombie behavior.

AI summary
A control execution apparatus is provided with a communication unit that makes an inquiry concerning a packet processing method with respect to a predetermined control instruction apparatus, and a packet processing unit that processes packets based on an instruction from the control instruction apparatus. The control instruction apparatus is provided with a communication history management unit that manages communication history between nodes via the control execution apparatus, a node state determination unit that determines, making reference to the communication history of the communication history management unit, whether or not a node that is a transmission source or a transmission destination of the packet for which an inquiry concerning a processing method was received, is on a side that provides a service to another node, and a control instruction unit that prohibits, when at least the node is on the side that provides a service to another node, new communication from the node in question to the other node.
