Risk Management The Big Picture – Part IV

In our next section we are going to introduce network-based intrusion detection. The detect engine in this case is either a firewall, a personal firewall, or an intrusion detection system. All of these work quite well. We will begin with a single attack, just to see how one might work and how we might detect it. Then we will explore the range of tools and show you how you can get in the game with a very low investment, possibly even free.
