Regarding the Internet access area in the data, the correct planning and deployment suggestions are:

  • A. DDos cleaning and detection equipment must be placed in the external network interface area to ensure that attack traffic is detected first.
  • B. Deploy IPS devices in the DMZ area bypass. If the defense function is realized, it is necessary to pass policy routing or static routing in the DMZ area switch to allow data to pass through the IPS devices.
  • C. FW1 is mainly used to prevent external illegal traffic from accessing the DMZ service area and to prevent attack traffic from inside the SSL tunnel.
  • D. FW2 mainly prevents internal illegal traffic from accessing the DMZ service area and illegally accessing the Internet.
