Cellular Network Security Function for Coordinated Attack Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cyberattacks on cellular communication networks are becoming increasingly sophisticated, with malicious software able to evade traditional security measures, leading to coordinated attacks that can degrade or disable cellular services.
Innovation Solution
A security function is deployed at network nodes to monitor network traffic for anomalous behavior indicative of coordinated attacks. This function can respond with attack mitigation procedures, collect data from connected devices to identify malicious code, and send instructions to isolate or remove the malicious code.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional security measures are used to detect malicious code, then device security is improved, but the measures become ineffective against sophisticated malicious software that can counter anti-virus
Solution Approach 1:
The patent introduces an intermediary component that acts as a bridge between the application and the operating system. This intermediary monitors system calls and communication patterns to detect malicious behavior without requiring direct access to the malicious code, thereby maintaining detection effectiveness against sophisticated threats while avoiding the limitations of traditional anti-virus approaches
Solution Approach 2:
The system implements feedback mechanisms where detection results and threat intelligence are continuously fed back into the security framework. This enables the system to adapt to new malicious software variants by learning from detected patterns and updating detection rules, thereby maintaining reliability against evolving threats
2Reliability
If security monitoring is implemented at network nodes, then coordinated attacks can be detected, but system complexity increases
Solution Approach 1:
The security function deployed at network nodes is designed to perform multiple functions: monitoring for coordinated attacks, detecting anomalous traffic patterns, identifying infected devices, and coordinating mitigation responses. By consolidating these functions into a single multi-functional component, the system achieves comprehensive attack detection without proportionally increasing overall system complexity
Solution Approach 2:
The patent merges the security monitoring functions across multiple network nodes into a coordinated system where nodes share threat intelligence and cooperate to detect and respond to attacks. This consolidation approach enables effective detection of coordinated attacks while avoiding the complexity of independent security implementations at each node

AI summary
The described technology is generally directed towards coordinated cellular network attack detection and mitigation. A security function deployed at a network node can monitor network traffic conditions for anomalous behavior indicative of a coordinated attack. In response to detecting the anomalous behavior, the security function can respond with any of several different attack mitigation procedures, in order to protect the network from the coordinated attack. Furthermore, the security function can collect data from connected devices, and use the data to identify malicious code. The security function can then send data and instructions to the connected devices to enable the connected devices to isolate or remove the malicious code.
