Security Basics: Re: Network Segregation to prevent spread of malware

[Michael Peppard <mpeppard () impole com>]

Speaking from experience, sadly you can get malware on a stand alone 
computer with no network access at all.
Your plan will do nothing but make your job harder and given how malware 
spreads, through and between the cracks you have to leave open for daily 
business, also do nothing to slow the spread of malware, viruses and 
assorted unwanted nasties. Your segregation is virtually useless if it 
already made it past the best your edge appliances could do.
You are better off with the best edge security you can get to keep the 
bad stuff out, decoupling and testing everything the outside world sends 
to your internal network, plus scanning and monitoring tools inside to 
find and contain outbreaks that make it past the edge appliances.
