Re: securing a segment of a network

Roger,

My first move would be to check with the auditors what level of
separation is required.

If they are happy with a single Domain then you could combine them and
leave each DC on its current network. Then use a firewall to keep the
networks separate, but add rules to allow:
   the two DCs to communicate as required and
   the clients on one network to communicate with the other DC as required

Alternatively, the auditors may be happy for you to use something
other than Windows Domains and you can still provide your organisation
with the services it requires.


If you cannot persuade them to allow a single Domain, for example,
laws or regulations forbid it, then you cannot combine them. In this
case, in my opinion, you have three possible options:
   1. Get the additional hardware and software and make the services
more resilient
   2. Continue as you are and make your organisation aware that they
cannot afford a better level of service
   3. Close the organisation and do something else

Securing Apache Web Server with thawte Digital Certificate
In this guide we examine the importance of Apache-SSL and who needs an SSL certificate.  We look at how SSL works, how 
it benefits your company and how your customers can tell if a site is secure. You will find out how to test, purchase, 
install and use a thawte Digital Certificate on your Apache web server. Throughout, best practices for set-up are 
highlighted to help you ensure efficient ongoing management of your encryption keys and digital certificates.
