Embodiment 1
[0022] Such as figure 1 The shown firewall policy data analysis device based on network traffic includes:
[0023] The mirror switch, connected to the switch, obtains all access data of the firewall;
[0024] The mirror traffic collection server preprocesses the data obtained by the mirror switch and generates corresponding txt files for storage;
[0025] The analysis device analyzes and merges the data according to the MapReduce algorithm to generate statistical reports.
[0026] In order to facilitate the rapid analysis of traffic data under large-scale data conditions, the mirrored traffic collection server stores the data in a distributed memory.
Embodiment 2
[0028] A firewall policy data analysis method based on network traffic, comprising the following steps:
[0029] Step 1. Establish bypass mirroring of firewall access data entry and exit, and collect all access data of the firewall in real time;
[0030] Step 2, preprocessing the image data format, extracting the feature vector and storing it in the form of a message;
[0031] Step 3. Analyze the data using a distributed computing framework.
[0032] In step 3, the analysis process specifically includes: 1. Filter the access traffic in non-IPv4 format; 2. Filter the access data that does not match the prefix, for example, the source IP prefix format for the destination IP access needs to be set in the firewall rules, for example, 192.168.15.*, all access addresses that do not conform to the source IP prefix format will be filtered by the firewall and access is prohibited; 3. Extract the access source IP data and the accessed destination IP data; 4. According to the access IP ...
