Abstract

The invention provides a risk assessment method and device for a terminal, relates to the technical field of communication, and solves the problem that a telecom operator cannot timely and effectivelyassess the risk of a smart home terminal. The method comprises the steps that a risk assessment device of a terminal acquires a first frequency and a second frequency of the current terminal, whereinthe first frequency is the frequency of the message sent to the first server by the current terminal, and the second frequency is the frequency that the current terminal receives the message sent bythe first server. The risk assessment device of the terminal predicts the risk level that the current terminal is attacked according to the first frequency, the second frequency and a preset model. The preset model is used for representing the relationship between the third frequency and the fourth frequency of the first terminal in the historical time period. The third frequency is the frequencyof sending the message to the malicious server by the first terminal. The fourth frequency is the frequency that the first terminal receives the message sent by the malicious server. The embodiment ofthe invention is applied to risk assessment of the terminal.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a method and device for risk assessment of a terminal. Background technique [0002] The emergence of smart home has brought convenience to users and greatly improved human life. At present, telecom operators have deployed tens of millions of smart home terminals, but these smart home terminals have become the targets of hackers. When a smart home terminal is hacked, it may cause large-scale network disconnection, distributed denial of service attack (distributed denial of service attack, DDOS), botnet (botnet) and other security incidents. [0003] At this stage, usually after a large-scale network disconnection occurs, it is judged whether the smart home terminal has been hacked according to the cause of the network disconnection, and then corresponding remedial measures are taken. Before smart home terminals are hacked, telecom opera...
