I need to see a synopsis of your anti hacking/anti penetration products. We are looking for something to protect DoD satellite control systems.
The best way to protect computers on a LAN network or in a facility is with the help of a firewall application. Avoid using anti-virus, because you will need to block incoming requests and the recommend applications are the ones created for this purpose. Use the database of Software Informer and pick one firewall that suits you best. Install it on all computer, and then access its settings. Add to exclusion all the network IPs and block all the incoming packages. This is a simple and effective way to protect the facility's computers.
