Hi Roger, First point: what you described bellow is nice, but it is one special scenario. What is the most likely threat you want to mitigate? Try to keep in mind, that mitigating exitic threats can lead you to higher costs and that is what you wanted to avoid acording to your first email. Also another question you can take in consideration: what would be your acceptable risks? If the requirement is: "Keep the same, maintain the accounting PCs unreachable from the other PCs in the network." then i read it as unreachable from the other PCs. A rule (ACL) can be applied on the respective PC which will deny all connections requests to it (inbound). That way you wont need to maintain 2 different domain controler while the requirement specifies PCs and not Servers. That way you can build your argumentation, if it doesnt help then you have no other choice than maintain 2 different networks or give up the business (as mentioned in the list) Cheers, Adam Pal -------- Original-Nachricht --------

Adam Pal escribió:Hello Roger, What exactly was your security gain from physicaly split the network?That makes the acocutning PC inaccesible from the other network. In theory, if you gain access to the gateway PC (with 2 network cars, one for each network segment) you could do something, but that would take a very skilled guy who can break into a Linux server and get the info from Windows shares.It would also help if you can specify what security requirement should be satisfied.Keep the same, maintain the accounting PCs unreachable from the other PCs in the network. ------------------------------------------------------------------------ Securing Apache Web Server with thawte Digital Certificate In this guide we examine the importance of Apache-SSL and who needs an SSL certificate.
