If you have an IPS sensor on the public part of your network (Perimeter) is it okay to have the Mgmt port plugged into the internal network? i.e. can the Mgmt interface be used to facilitate an attack if the device was comprimised?
And does this answer apply to routers and ASA's also?
The management interface of any managed device should be on your management network. The sniffing (promiscious mode) or in-line interfaces should be relitively immune to attack (compared to a normal host interface, or even the management interface of the IPS sensor).
I worry more about the management interface of the sensors than the in-line interfaces. Cisco has been slow to adapt external authentication, password aging/enforcement etc.
