I am a network administrator in company. I read this article eject any wifi device from network with android
Some of employers are using mobile phones and company`s wireless network. Theses employers are not related with IT. So, they use WIFI for browsing web. (i can not to give them WIFI password, but some employee need WIFI for work) Of course, they can plug laptop in any available wired socket (yes, i can unplug unused sockets in server room).
How i can protect my local network from arp spoofing? I don't want to make static arp table. I read wikipedia article ARP_spoofing
Is there a way, that i can setup some software on our linux server and protect whole network or need to made some configuration on each computer? Also we are using VPN (openvpn), if that matters.
Can i drop arp requests in WIFI routers? Or they are required for DHCP to work? DHCP requests from WIFI routers are forwarded to linux server.
One think with wifi is that maybe i need to isolate public wifi in VLAN? For that i need wifi router that support VLAN and also switch that support VLAN, and our linux firewall`s network card too must support VLAN, right?
And if i prevent ARP spoofing, then MITM attack is possible ?
