What are three techniques for mitigating vlan attacks?

Three techniques for mitigating VLAN attacks include: 1. **Port Security:** Limits the number of MAC addresses allowed on a switch port, preventing MAC flooding and unauthorized device connections. 2. **DHCP Snooping:** Validates DHCP messages, blocking rogue DHCP servers and preventing IP address spoofing. 3. **Dynamic ARP Inspection (DAI):** Validates ARP packets, preventing ARP poisoning and man-in-the-middle attacks by ensuring correct IP-to-MAC address bindings.
