How to block Internet sharing by MacBook on Cisco Switches Cisco Vulnerability
I have a issue, on my LAN we found a vulnerability, the MAC laptop (MacBook Pro) had a sharing internet featuring. using Ethernet cable connected and you can share internet ussing AirPort to the other devices, you can configure the MAC as Access Point and make a NAT on the network.
I applied the port-security using max 2 mac address and switchport protect and spanning-tree bpduguard and traffic still passing. If you analyze the traffic you will only see the ip Ethernet cable, even apply the dhcp snoop give a IP address on devices connect to the MacBook.
Not sure if there is any feature to prevent ad-hoc wireless networks originated from a user machine from a Cisco Switch stand point of view, generally the User IT dept will create a GPO to disable ad-hoc networking on user wnic's or you have the wireless dept that keeps an eye on the any rogue AP's popping up in your network.
I am sure the Wireless Controllers now are capable of switchport tracing for rogue AP's and err-disable them as well.
