Enabling Deep Security Defense and Loading the SAC Signature Database

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. 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.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run engine enable

    Deep security defense is enabled.

    By default, deep security defense is disabled.

Verifying the Configuration

Run the following commands to check the previous configuration.

  • Run the display sa information command to check the SA status. If the SA is enabled, deep security defense is enabled.
