There are many threats out there today, which are of concern to the network security analyst. Some of the threats can be mitigated to a certain extent through the use of various hardware, and software solutions. A good example of this would be how you defend against that ever-present pest; distributed denial of service attack. Several vendors have come up with some good hardware solutions for this network attack. Much like other vendors have sold enterprise class firewalls to help protect the corporate network. What the two above noted examples have in common though is that a solution is provided by a third party. These solutions are easily implemented with a little vendor side training for the in-house network security staff.
