With the rapid development and high dependence on network applications, network security has become an issue that every enterprise and individual must pay attention to. Regardless of the application scenario, switches, as an important part of network infrastructure, bear the heavy responsibility of data transmission and communication, so it is crucial to establish basic network protection.

The application deployment that is commonly used on the switch can use the three key functions of DHCP snooping, Dynamic ARP Inspection (DAI) and IP Source Guard (IPSG) to work together to establish network protection. How they work as follows:

DHCP Snooping

Acts like a firewall between untrusted hosts and trusted DHCP servers. Snooping establishes and maintains a DHCP binding database of used/leased IP addresses, verifies message sources, and filters traffic to enforce rate limiting.
 

Dynamic ARP Inspection (DAI)

Used to verify Address Resolution Protocol (ARP) packets in the network. DAI allows network administrators to intercept, log, and discard ARP packets with invalid MAC and IP address bindings, protecting the network from hacking attacks such as theft, tampering, and spoofing
 

IP Source Guard (IPSG)

Based on dynamic binding data from DHCP snooping and administrator-defined static bindings, It performs information cross-checking of host IP addresses, MAC addresses, VLAN IDs, and access ports. This helps identify and block unauthorized hosts from accessing the network using spoofed IP addresses.

The EtherWAN switch series protect the network in which it is deployed by bringing these three key features together:

First, DHCP snooping establishes and maintains the binding table.

DAI uses the binding table from DHCP snooping to verify ARP packets, ensuring that only legitimate ARP requests and responses are processed.

IPSG uses the same binding table to filter IP traffic, allowing only packets with valid IP-to-MAC address bindings.

By working together, these features provide a robust security framework that prevents ARP spoofing and IP forgery, dynamically responds to abnormal network behavior, and promptly blocks potential attacks, ensuring the security and stability of the network environment.

In addition, you can also use the function settings of Port Security, Access Control Lists, Private VLANs, 802.1x Network Access and Storm Control to collaboratively protect your network and further enhance network security and stability.

A complete switching security configuration can not only help protect the enterprise's internal network from malicious spoofing and masquerade attacks, but also improve the efficiency of network management and reduce the occurrence of security incidents.

EtherWAN focuses on switch manufacturing, not only providing efficient and stable connections, and spare no effort in network security protection. Please visit the following product pages to ensure the layout of your important facilities:
