Hi:
to tell the truth, I was thinking to post a query regarding IDS informer. I worked with IDS informer and observed some points.
1. I m still not clear on "how IDS informer decides that attack was not detected?"
2. On false positives, we observe that so called U traffic, corresponding to an attack, mainly differs in the response part. in this case, if an IDS/IPS detects the attack, it flags it as false positive. but it should be noted that attack is launched against a target. Now, i m confused on one thing- for an IDS/IPS, what should be the modus of operandi? should it detect an attack on the very moment it is launched, or it should wait for the response from the target to see if it is really successful? In the second case, though FP may be reduced, but for an IPS, it can be dangerous thing.
3. sometime, packet level auditing and connection level auditing differs, as far as the final results are concerned.
please impart your expert views

regards
Sanjay

I have been involved in working in this area for a number of years now and
my previous company was Blade Software where I developed IDS Informer and
Firewall Informer to provide similar testing capabilities.

Information on Traffic IQ Pro is available below should you want to take a
look.

Working with testing labs and a number of security and networking vendors
has enabled Traffic IQ Pro to be a really useful tool for anyone who wants
to check the configuration of their firewalls, IPS, IDS, routers, switches
etc and see how those devices perform under different scenarios.

Another question for everyone,
When you brought in each vendor for evaluation, did you configure a test
network for them or did you use your production network? My 1st concern is
keeping my job :o) If I test in production, I could impact production
traffic. If I don't test in production, how can I best ensure that I won't
have problems with custom applictions, older IP stacks which could be an
issue if RFC compliance checks are done, etc.
The vendor answer is always, "don't turn on blocking and just monitor." Is
that a reality? I'd like some testimonials to this and some real life
instances of what has been done from unbiased sources.

Thanks,

VT

Re: IPv6 support in IDS/IPS products

I'm a little surprised. I have only heard back from two vendors that claim to do full IPv6: NFR & ISS. I doubt this is an accurate representation, so I'll try one more time.

RE: Intrusion Prevention requirements document

IDS Informer like Traffic IQ Pro is an advanced packet replay tool and can be used to validate inline and passive intrusion detection/prevention systems. In both instances the applications have no concept of the device being tested and therefore has no understanding on the outcome of the attack, it is just generating the traffic, the only information it has is if any of the packets are failed to be delivered. A successful attack within both applications is based on whether or not all of the packets in the traffic files were received by the opposing network card. The difference between the successful and unsuccessful traffic files themselves is, as you correctly pointed out, based on whether the particular attack/exploit was successful. In many cases it is important for an IDS/IDP to know the difference. Taking a simple example such as the DNS Zone Transfers - escalation procedures may require remediation work if an IP other than a secondary DNS was able to transfer zone details. In this case the successful file would be used. If on the other hand you wanted to ensure that all unsuccessful attempts were logged but not acted upon then you would use the unsuccessful event. In both cases an IDS/IDP should be able to differentiate between the two and alert accordingly. Your second point in relation to attack detection and false positives is interesting. It is well known that network based intrusion detection/prevention systems can be produce a high degree of false positives and unfortunately IDS Informer can add to that as it will attempt to replay the remainder of an attack even though it has already been detected and blocked. Traffic IQ Pro does not have this problem and will not cause additional false positives. The second part of your question is more of a theological debate however. >From a standpoint of "all attacks should be detected and blocked prior to execution" I would expect an IDS to detect the attack prior to it reaching a point that could cause a compromise to my internal/protected systems although this is not always possible. In some cases though it is best to let the attack take its natural course for evidential purposes. For me, if an attack succeeds then its too late, the damage has been done. It is worth pointing out that in many cases it is not possible to detect an attack at the point of inception as there is not enough information available to make an accurate determination. There is a bug in IDS Informer that prevents it from displaying the correct information in certain scenarios. This can lead to different information being displayed for an audit and packet level report of the same event. Traffic IQ Pro does not exhibit this flaw. Using Traffic IQ Pro it is possible to run an audit level report for multiple files to determine which succeed and which fail. Then typically a packet level report would be run on the ones that failed to determine at which point they failed to see if the detection point is acceptable. For instance, blocking an attack at packet 47 when the attack can be run in 46 is not very useful.
