Problems solved by technology

At present, the main common attack method in the communication system network is DDoS attack. The characteristic of DDoS attack is simple and easy to occur. The attacker can forge a large number of IP addresses to send a large number of messages to the target host, and block the service by consuming resources, making the target server down
At present, CTC still uses the firewall as the main passive defense method, and the intelligent active defense capability is insufficient.

Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] The present invention is a network security risk prediction method based on railway dispatching set system, such as figure 1 As shown, the specific steps are as follows:

[0022] Step 1, generate normal network data and abnormal network data by simulating the network environment;

[0023] Specifically: Obtain the traffic data of the simulated network interactive system, process and manually mark it, and obtain 100,000 pieces of original network data;

[0024] The keywords of each original network data are: time (time, string type), source IP address (s_IP, string type), destination IP address (d_IP, string type), source port number (s_port, integer type) , Destination port number (d_port, integer type), connection time (duration, integer type), protocol type (protocol, string type), send bytes (size, integer type), label (label, inte...

Abstract

The invention discloses a network security risk prediction method based on a railway scheduling set system, and the method comprises the steps: firstly, obtaining original network traffic data, processing the data, and enabling each piece of data to comprise keywords: time, sIP, dIP, sport, dport, duty, protocol, size and label; converting the sIP into a vector, and carrying out dimension reduction processing to obtain a vectorized set vector SIP (Session Initiation Protocol); the method comprises the following steps: classifying original network traffic to obtain an abnormal IP vector set abnSIP; whether the infection risk exists or not can be judged by judging the distance between the IP address in the vector SIP and the IP address in the abnSIP. According to the method, the railway dispatching centralized system can be effectively protected, the IP address with potential risk is marked by judging the distance from the abnormal IP address, and the safety of the railway operation environment is improved.

Description

technical field [0001] The invention belongs to the technical field of rail transit communication, and in particular relates to a network security risk prediction method based on a railway dispatching set system. Background technique [0002] In the railway operation system, the centralized dispatching system (Centralized Traffic Control System, CTC) is the core equipment of traffic command. It is mainly used for centralized supervision and control of station signal equipment in a certain section by the control center, and direct control of train operation. Management and unified command. [0003] From the perspective of logical architecture, the dispatch center system has a three-tier structure. The first layer is the dispatch center system of the Railway Corporation. There is only one in the country, and it is responsible for coordinating the national railway bureaus. The second layer is the dispatching center system of the railway bureau. There are 18 in the country, whi...
