|And may I know why you are assuming that it is some homework assignment?|
I am on a project and am trying to provide security solutions for a network of process controllers. I am from an engineering background and do not have much knowledge on viruses etc and am not able to find anyone who has knowledge in this field and articles on the internet do not help much in the specific doubts that I get.
I have read up articles but had a doubt as to whether a virus which had been designed such that it spreads through a network using may be say TCP/IP protocol also spread through a network using some other kind of protocol say Profibus protocol etc.
Firstly this is not a question which someone else had raised. I was myself wondering if any protection is even required! I do not know how the TCP/IP protocol works but had a vague idea that it will have a particular kind of a structure and a code designed to spread through network exploiting this particular structure should not make much sense in case of some other structure(used for another kind of a protocol)
(1)I had firstly wanted to know if this idea even made sense, i.e. can viruses be written for / are they written specific to some kind of communication?
(2)If a virus that can crash a windows based system communicate through a wireless connection/ fibre optic cable etc?
