Abstract
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.
Claims18
A method comprising:
- detecting, by a network security device of a private network, a denial of service (DoS) attack in network traffic observed by the network security device;
- determining, by the network security device, whether the DoS attack is being transmitted through a cellular modem associated with a cellular data network;
- and
- reducing, by the network security device, data usage of the cellular modem when a result of said determining is affirmative.
1 more element
A network security device comprising:
- a non-transitory storage device having embodied therein instructions representing a security application;
- and
- one or more processors coupled to the non-transitory storage device and operable to execute the security application to perform a method comprising:
- detecting a denial of service (DoS) attack in network traffic of a private network protected by the network security device;
- determining whether the DoS attack is being transmitted through a cellular modem associated with a cellular data network used by the private network;
- and
- reducing data usage of the cellular modem when a result of said determining is affirmative.
