Trusted Network Interface for Botnet Defense
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Botnets comprising millions of compromised computer systems pose significant threats for cyber attacks, including denial of service attacks and identity theft, as existing technologies lack effective methods to thwart these threats without infringing on user privacy and requiring extensive technical support.
Innovation Solution
A trusted network system comprising network security appliances interposed between computer systems and the public network, which receive digitally signed and encrypted control commands from a management system to execute defensive and offensive actions against botnets, utilizing peer-to-peer data exchange and unique security certificates to secure communication and minimize attack risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network security appliances are deployed to defend against botnet attacks, then security protection capability is improved, but system complexity and technical support requirements increase
Solution Approach 1:
A trusted network interface acts as an intermediary component within the network security appliance, mediating between the public network and private network. This interface simplifies the overall system architecture by providing a standardized, pre-configured security boundary that automatically enforces security policies, thereby improving security protection capability while reducing the complexity of manual configuration and technical support requirements.
2Reliability
If trusted network interfaces with automatic updates are implemented, then security response effectiveness is improved, but automation extent increases
Solution Approach 1:
The trusted network interface implements self-service capabilities through automatic update mechanisms that enable the device to autonomously download, validate, and install security signature updates without requiring manual user intervention. This self-updating functionality improves security response effectiveness by ensuring the appliance always operates with the latest threat intelligence, while the automation is designed to be transparent and non-intrusive, maintaining user control over the overall system.
3Reliability
If digital certificates and encryption are used to secure control commands, then communication security is improved, but processing time and computational overhead increase
Solution Approach 1:
Digital certificates are pre-installed in the trusted network interface during manufacturing, establishing cryptographic trust relationships before the device is deployed. This preliminary configuration eliminates the need for time-consuming certificate installation and validation processes during operation. When control commands are transmitted, the pre-established trust relationships enable rapid verification of command authenticity and integrity, thereby maintaining high communication security while minimizing processing time overhead.
