I want to buy and install an intrusion detection system. Our purchasing department is telling me that I have to provide a list of specifications for an intrusion detection system that can be used to evaluate the features of competing products. Given the little I know of the different approaches that IDS systems use, this seems a difficult task. From time to time I have been surprised by the high levels of ability of people posting on this list and I think that some of them must have been through this evaluation process before. Can anyone e-mail me a starting point for evaluation specifications please, or point me to a good source? Brian Smith, DOS Dummy
