We are running 2 networks (not connected to each other) and the back network is connected to a T1 line with no firewall. There is one PC that from time to time, drains the resources of the rest of the PCs connected to the T1. Today, someone took control of this PC and opened the Command prompt. The transcriptionist on this PC quickly cut power to her PC since she no longer had control of her mouse or keyboard.
Our “boss” states that the firewall should be provided by the T1 service but I don’t think this is true. I don’t know what kind of hacker was on the transcriptionist’s PC or why her PC seems to be the point of entry but this is not the first time that she’s lost control of her PC to what appears to be a hacker.
I have no experience with installing and configuring a firewall and have come across conflicting instructions as to how to go about this (since I know the boss won’t pay to have someone come in and configure the firewall).
Questions:
1. Does anyone knowof a good reference for configuring firewalls?
2. Why would one PC drain the others on the T1 line?
3. Any way around cutting power to stop a would-be hacker?
Thanks!
