Security setup advice

Well, the family is thinking of setting up a business, and im in charge of their security.
First off, its not going to be a HUGE business, probably will have anyway from 2-3 computers.


The security setup i have in mind is as follows:

Defensewall
Sandboxie
Shadow Defender
Router+Hardware Firewall
Truecrypt (important files)
Random on demand scanners
True Image



What do you think?
I plan on using shadow defender's commit to disk feature to only save the "important" files needed to true crypt, and that, will be in a separate external hardrive

 

i think Defensewall plus Prevx3 will be close to bulletproof

 

Then, i might get that, as the on demand scanner...

So now, its


Defensewall
Sandboxie
Shadow Defender
Router+Hardware Firewall
Truecrypt (important files)
Random on demand scanners
True Image
Prevx

 

remenber to scan your files for any posible infections for just in case there is a doubt

 

For starters, only one of the computers will contain most of the business files and information, therefore that one computer must be isolated from the rest of the Network.
Two Firewall Routers will be needed, one for the main business computer and the second for the remaining computers in the Network.
The topology will be as follows:

01)- Internet connection

02)- Modem

03)- Out of the Modem into the WAN Port of Firewall Router one with DHCP enabled, obtain an IP automatically, Router IP 192.168.1.1, DHCP Range 192.168.1.111 to 192.168.1.113, and
static IP addresses between 192.168.1.2 to 192.168.1.110, the main business computer plugged into Port one, allowing two more devices to use DHCP if needed and an static range for backup device/printer
Computers behind Firewall Router one (192.168.1.1) will belong to Workgroup 1

04)- Out of Firewall Router one, Port two, into the WAN Port of Firewall Router two with DHCP enabled, obtain an IP automatically, Router IP 192.168.2.1, DHCP Range 192.168.2.111 to 192.168.2.115, and
static IP addresses between 192.168.2.2 to 192.168.2.110, the other computers plugged into Ports one through four, allowing five devices to use DHCP if needed and an static range for backup device/printer
Computers behind Firewall Router two (192.168.2.1) will belong to Workgroup 2

05)- All computers have access to the Internet, all computers can use DHCP or have static IP, computers behind Firewall Router one can not see computers behind Firewall Router two and visa versa

06)- Keep the security software on the main business computer as light as possible and maintenance free as possible with good imaging and off site backup
