Dynamic ARP inspection is a network security feature that prevents attackers from exploiting the address resolution process. It validates the communication based on a trusted database, ensuring the legitimacy of the address bindings. While Port security is instrumental in securing a network against unauthorized devices based on their MAC addresses, it does not specifically validate address resolution packets. Access Control Lists provide packet filtering capabilities but do not validate address binding legitimacy. Lastly, DHCP snooping can build a trusted database for Dynamic ARP inspection to use but on its own, does not validate address resolution packets.
