Feature library upgrading method and device for network security equipment

The invention discloses a feature library upgrading method and device for network security equipment, and the method comprises the steps: packaging an obtained updating feature library into a feature library upgrading file according to a preset file format, and enabling the feature library upgrading file to comprise a multi-field module and a feature binary module, wherein binary analysis data obtained by analyzing each piece of feature data in the updated feature library is stored in the feature binary module, and a plurality of preset fields are stored in the multi-field module and comprise binary data length fields used for representing the size of the binary analysis data; and finally, upgrading the feature library according to the feature library upgrading file, and reading the content stored in the feature binary module into the target memory. According to the upgrading method, the feature library upgrading file is processed into the preset format in advance, so that the binary analysis data in the feat
