Well inasmuch as the report is not ready RIGHT NOW this is probably not what you want to hear... But.... We are currently testing a whole bunch of these IPS doohickeys and the report - including exactly the test results you are seeking (amongst many others), will be published in December. In the mean time, check out our latest IDS reports at www.nss.co.uk/ids and www.nss.co.uk/gigabitids Regards, Bob Walder Director The NSS Group ------------------------------------------------------------------------ ---------- This message is intended for the addressee only and may contain information that may be of a privileged or confidential nature.

It would be good if they were any reviews that would include graphs and performance deterioration in terms of throughput performance after an IPS has been put in. What would be interesting though is whether the IPS fulfills the expected requirements which primarily to me is to do a good job in dealing with potential attacks and allow the administrator more time in other tasks. To me, the prospect of using IDS and reviewing logs everyday seems like a very time consuming prospect, any opinions on this from any who are currently in such a situation? I've evaluated some IDS products and felt that the management console is taking up a lot of resources especially when it is extracting data from the IDS appliance and refreshing constantly, any similar experiences? Also, my question to any is the following "One note of caution on TCP Reset is not a preferred method of blocking attacks according to some security experts. " Alan Shimel Why isn't TCP reset a preferred method of blocking?

An idealsolutionwould be to be able to detect the patterns and prevent them automatically, can a network IPS do this? I understand that it is possible in some IDS to do a TCPreset afterone had confirmed that the connection is not acceptable,can anyoneexplain whether an IDS that can do this be actually "active" as opposed to passive? It would also be interesting if there could be some amountof trendanalysis built in which can review the destination/sourceip trafficover time, which can be used to identify particular boxeswhich areeasily targeted, which would mean that more work needs tobe done forthat box.
