Enabling Deep Security Defense and Loading the SAC Signature Database
Context
To use the SAC function on a device, you need to purchase the corresponding license and enable the deep security defense function. The SAC identifies applications by using the signature database file. By default, the system software has an embedded signature database file. After the deep security defense function is enabled, the system automatically loads the embedded signature database file. The remaining memory space of the device must be greater than the size of the signature database file that is used. Otherwise, the signature database file fails to be loaded.
