Enabling Deep Security Defense and Loading the SAC Signature Database

Enabling Deep Security Defense and Loading the SAC Signature Database


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. To use a signature database file of a later version, you can upgrade the signature database file separately. For details, see Upgrading the SAC Signature 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.


  1. Run system-view

    The system view is displayed.

    By default, deep security defense is disabled.
