Error 404--Not Found

From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:

10.4.5 404 Not Found

The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.

If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.

There are network-based intrusion-prevention systems that work so accurately and so reliably that network managers who decline to even consider using them out of worry IPS generates false positives or in-line equipment crashing must now re-think that position.

That's the bottom line you'll find in the 300-page report from NSS Group, the network-equipment evaluation lab that put IPS from Internet Security Systems, NetScreen Technologies, Network Associates, TippingPoint Technologies, and Top Layer through a grueling series of tests. Four out of the five vendors came through with flying colors.

NetScreen's IDP 500 failed to make the grade this time, probably due to some beta code acting up, but TippingPoint's UnityOne appliance impressed NSS Group so much it gave it a coveted "Gold" status. ISS, Network Associates, and Top Layer also earned the NSS group "approved equipment" rating by showing their IPS gear works accurately in blocking attacks and remaining reliable at high speed.

Every vendor that had the guts to submit their equipment to this level of scrutiny, knowing the results would be public, deserves a round of applause. Read our story about the NSS Group test on IPS, then let us know why you still don't want to even consider using them.

I find it hard to believe that you did not include Cisco Security Agent (formerly Okena Stormwatch) in your IPS testing.

I have tested CSA and found it to be the most comprehensive IPS tool available today! Readers should be made aware of CSA.

Maybe because the article talks about Network IPS and not Host IPS.

BTW It is a pity Okena got bought by cisco, I hope they do not kill another product!

We had Okena on our list and then the Cisco takeover happened - they simply could not sort out the required resources during such a hectic time and so had to pull out before testing - we hope to have the Cisco (ex Okena) offering in the second edition of our IPS report
