Abstract

The application includes a data processing device and method. In an embodiment, the data processing device includes a data collection unit, configured to collect data transmitted in a network, and divide the collected data, according to a predetermined feature, into known attack data and unknown attack data. The data processing device further includes a data conversion unit, configured to replace, according to a mapping database, at least a portion of the content included in the unknown attack data with corresponding identification codes. Therefore, the size of data transmitted in the network can be reduced.
