La méthode la plus efficace pour prévenir les attaques par usurpation d'ARP

Maintain a static ARP table on critical devices, associating IP addresses with their corresponding MAC addresses.

This can thwart attackers attempting to manipulate the ARP cache.

Static ARP entries prevent ARP spoofing by creating a trusted list of device addresses.

By enabling features like port security and static ARP entries, you can limit who can connect and how they connect.

we can start by simply creating the static ARP tables and disabling the DHCP.

En switches se pueden utilizar el DHCP snooping y el Dynamic ARP Inspection (DAI).

Keeping software updated and passwords strong makes it harder for attackers to exploit weaknesses.

Additionally, segmenting your network and using endpoint security can create multiple lines of defense.

These steps working together can significantly reduce the risk of ARP spoofing compromising your network.

we can also disable the broadcasting of the SSID of Wireless Network & using the stronger encryption method for the authentication.
