LAN interface/control project

Dear All,

I could be involved in a new project as hw engineer. The main issue is to
interface/connect some kind of control machines via LAN. I think remote log
and fw upgrade could be requested too.

I've got hardware design skills, mainly from industrial controls and sensors
area and I've got firmware design knowledge too, mainly from teamworking on
energy conversion devices.
At the moment I think that the project is 30% hw and 70% shared between
uC-firmw and PC-softw.

I feel confident with the hw part... but I was never asked to design a LAN
interface (neither hw nor sw), and I'm actualy not confident with
ETHERNET/TCP-IP protocols, so I need to close the gap, starting from
(re)studying the matter. Even if I'm not expeted to develop the firmware
(not all, anyway) I would like to be able to interface with sw and fw
engineers.
Can anybody direct my to some "incremental" readings, from the basic to
security issue regarding remote controls over internet ?

Thanks in advance, and Merry Christmas.
