Cellular Modem Data Management During DoS Attacks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During Denial of Service (DoS) attacks, cellular data networks experience rapid data usage overages, leading to inactive internet connections, slow connectivity, and excessive billing due to high traffic volumes, which existing technologies fail to effectively manage.
Innovation Solution
A network security device detects DoS attacks and reduces cellular modem data usage by configuring the modem to lower transmission speeds or filtering out malicious traffic at the cellular data network level, thereby preventing excessive data consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cellular modem is used for Internet connection during DoS attacks, then Internet connectivity is maintained, but data usage increases rapidly causing overages and connection inactivation
Solution Approach 1:
A network security device is introduced as an intermediary between the cellular modem and the network traffic. This device monitors incoming traffic, identifies DoS attacks, and controls the modem's transmission behavior to prevent excessive data consumption while maintaining legitimate connectivity.
Solution Approach 2:
The system dynamically changes the transmission speed parameter of the cellular modem based on detected traffic conditions. When a DoS attack is detected, the modem's speed is reduced to lower data consumption; when normal traffic is detected, full speed is restored to maintain connectivity quality.
2Productivity
If cellular modem transmits at full speed to maintain connectivity, then Internet access is reliable, but DoS attack traffic consumes excessive data causing overages and throttling
Solution Approach 1:
The cellular modem's transmission speed is made dynamic rather than static. The system continuously monitors network traffic characteristics and adjusts the modem's speed in real-time, increasing speed for legitimate traffic and decreasing it during DoS attacks to prevent data overages.
Solution Approach 2:
The network security device provides feedback about detected traffic patterns to the cellular modem. When DoS attacks are detected through analysis of traffic volume and patterns, the system sends control commands to reduce modem speed, creating a feedback loop that prevents harmful data consumption while maintaining productivity for legitimate traffic.

AI summary
Systems and methods for managing data usage of a cellular modem during DoS/DDoS attacks are provided. According to one embodiment, a network security device of a private network detects a DoS attack in network traffic going through the network security device and determines whether the DoS attack is being transmitted through a cellular modem of a cellular data network. The network security device reduces data usage of the cellular modem when the DoS attack is detected and the DoS attack being is transmitted through the cellular modem.
