In order to improve the reliability of traffic forwarding, the ISP routing function can be used together with the health check function to ensure that traffic is not forwarded to f...

In addition to detecting link connectivity, health check can also detect link delay, jitter and packet loss rate in real time. Reference health check and link quality indicators in...

Firewall virtual system allocates resources

AD domain authentication is an implementation method of LDAP authentication.

A Word document file.doc can be renamed to file.exe, but the firewall's file filtering mechanism can still identify the true type of the file.

BGP traffic diversion only supports manual traffic diversion.

The difference between DoS attacks and DDoS attacks is that DoS attacks are usually initiated directly by the attacker, while DDoS attacks are usually initiated by the attacker con...

Endpoint security is SSL A method in VPN to check whether the terminal is safe, including host check when the user accesses the virtual gateway and cache clearing when the user exi...

When configuring the SSLVPN port forwarding function, the security policy only needs to allow traffic between Untrust and Trust.

IPSec VPN does not support the encapsulation of non-IP unicast packets.

IPSec uses an asymmetric encryption algorithm to encrypt transmitted data.

As shown in the figure, in this scenario, NAT traversal is enabled, and the security policy configuration of firewall B regarding NAT traversal is as follows. If other configuratio...

In scenarios that require high reliability of IPSec services, it is recommended to enable the DPD detection function on the devices at both ends of the tunnel at the same time to e...

After completing the configuration of policy routing intelligent routing, subsequent traffic passing through the firewall will be forwarded according to the routing policy. Some of...

The smart DNS function needs to be used together with the NAT Server function and the source- in- source-out function.

When assigning interfaces to a virtual system, the management port cannot be assigned to the virtual system.

When allocating resources to a virtual system, some resources are a fixed number of resources that are automatically allocated according to system specifications and do not support...

The figure shows the load balancing network. Firewall A and firewall B establish IPSec VPN tunnels with firewall C respectively. When a link failure occurs between firewall A and f...

When administrators create a firewall virtual system, they also need to create a VPN instance with the same name to isolate routes.

Huawei firewall only supports bandwidth limitation in the outbound direction of the interface.

In a multi-exit scenario, when there are multiple equal-cost routes or default routes to the destination network, the global route selection policy is matched. The firewall can dyn...

Policy routing is a mechanism that modifies entries in the routing table according to user-defined policies and then selects routes after the routing table has been generated.

As shown in the figure, the firewalls at both ends establish GRE over IPSec. The original packet is first encapsulated by IPSec and then GRE encapsulated.

SSL VPN is based on B/S architecture and does not require client installation.

The key to DDoS attack defense configuration is the reasonable configuration of the threshold. If the defense threshold is set too low, the system will activate the attack defense...

If the attack frequency of ICMP Flood attacks does not exceed the reading value, the security device will not activate preventive measures.

In firewall content filtering, keyword recognition can perform corresponding actions based on weight values.

Content filtering includes file content filtering and application content filtering.

URL filtering is more granular than DNS filtering and can be controlled to the directory and file levels.

When a POP3 or HAP message is detected, if it is determined to be an illegal email, the firewall's response action can only be to block the email.
