I have to design a Highly secure Local Area network of 35 systems.

There have been data theft issues arising from internal staff and I need to address this problem. I have a tight budget and hence looking for Free or reasonably priced solutions. I not a technical person and would be more happy to work with solutions with freindly graphical interfaces.

I am prepared to install Active Directory, and any other software  or change switches if required.

Current Infrastructure :

3 Switches
3 SQL servers - win 2003
1 Sugar CRM server- Win 2003
1 Linux Fire wall server - Endian
25 desktops - Win xp
5 laptops.- Win xp

    Assisted Solution

    This is a LAN network with 35 systems, do you anticipate growth for the future?
    Is the data files on a network share drive?
    How are your users accessing shared resources?
    What is Sugar CRM server?
    As far as the Laptops do thay access the network through wireless?
    What kind of backup plan do you have in place?

    Many option to lock down your network:

    You can run DCPROMO on Windows Server 2003 and create a domain.

    Once Active directory is installed you can then create Groups/Users and apply NTFS/share permissions to any network shares, to prevent any data to be copied, deleted, etc.. You will also be able to apply Group Policy to any OU/computers. They see what you want them to see on the network.

    Note: All systems will have to join that domain in order for policy to take place.

    Have a Company Network Policy
    I would recommend any moble device that gets on the internet anywhere else, to never get back on your network.

    All Servers must have a server AV installed and monitored. All desktops and laptops must have a Client AV and monitored. This should be enforced at the gateway, so no AV no access to the internet.

    You can utilize what you have currently, however depending on how important your data is, a little investment can go a long way.
