In URL filtering, custom URL categories have higher priority than predefined URL categories.

By default, there is a default bandwidth policy on the firewall. All matching conditions are any (any), and the action is to discard the traffic after exceeding the current limit.

SYN scanning requires the establishment of a complete TCP connection, and the SYN scan will be recorded in the system log.

In firewall URL filtering, the priority of the blacklist is higher than that of the whitelist.

Policy routing traffic diversion is a static traffic diversion method.

Attackers use address scanning attacks to determine which target systems are active on the target network.

Since AH's integrity check on data will perform a hash operation on the entire IP packet including the IP address, address translation will change the IP address, thus destroying t...

The third-party access device added to iMaster NCE-Campus supports connection using the TACACS protocol.

In order to check whether there are abnormal connections on the Windows host, an engineer can use the netstat command to view the currently active TCP connections on the host. The...

SSL VPN uses a web proxy to allow mobile users to access intranet web server resources through the firewall as a proxy.

When accessing the virtual gateway, the user terminal needs to pass the host inspection policy before the user can successfully access the SSL VPN.

IPSec VPN is a three-layer VPN and can provide encryption protection for the IP network layer.
