Re: SLAC List of Network (both LAN and WAN) Monitoring Tools
I think the value of that list as a general reference is more historical and evolutionary in nature.  For what folks prefer, SANS Institute papers and any one of the reputable security news websites (DR comes to mind) will have a breakdown of what is currently in popular use (or not popular, but recommended by respected InfoSec engineers).

Re: SLAC List of Network (both LAN and WAN) Monitoring Tools
"... you search Stanford(dot)edu for "Monitoring Tools" you'll quickly find it." I like open source option. I just checked it there are two many of them. Is there not any outstanding people use most often than others?

Re: NetFlow vs SFlow
"Sonicwall NSA does not support sFlow or even "netflow". It supports IPFIX, which is the IETF Standard"

Ok. This answers my previous question. Makes sense.

Re: Neither of the two for enterprices
"To me an inline DDOS solution that can inspect each and every packet up to the max. bandwidth of the environment is a much better solution. .."

That makes sense, what comes to my mind how this would impact the overall network performance.

DDoS Detection?
Thanks, nice article, enjoyed reading it. It is sad that all we can talk about detection.

SLAC List of Network (both LAN and WAN) Monitoring Tools
I've only ever used Free and Open Source (FOSS) NMTs, and NetFlow and sFlow were never in my list of apps to review.  However, there are a large number of them out there and I highly encourage people seriously researching what is best for them to take a trip to the SLAC (Stanford Linear Accelerator Center) list of Network (both LAN and WAN) Monitoring Tools.  I've referenced this page for years and there is a nicely organized format ordered by year from 1996 to 2015 (as of my last visit) of over a hundred app, most with live links to the project pages.  I can't add the URL here, but if you search Stanford(dot)edu for "Monitoring Tools" you'll quickly find it.

Now, toward the question, I don't have to have used either to have an opinion; just based on experience with many of the soft solutions out there, I knew I wanted something more.  If you are attacking any major network analysis project, in-line monitoring is the only way to go.  Google it for plenty of good information on in-line bandwidth meters and network interface chips.  I've seen maker projects that built inexpensive in-line setups that would serve the purpose functionally, if not attractively!  Remember, full-duplex is ubiquitous...  Spend wisely and your network tap could become your best friend.

Re: NetFlow vs SFlow
Sonicwall NSA does not support sFlow or even "netflow". It supports IPFIX, which is the IETF Standard. It is fully compliant with the IPFIX standard. V9 is the precursor to the standard and has been the "de facto standard", but is missing some features like enterprise elements and variable length strings. Initially the exports did not have a proper active timeout, but this has since been remedied in more recent releases. This is NOT a limitation from sonicwall. This is a limitation of the collector you are using. Plixer's Scrutinizer fully supports all Sonicwall IPFIX exports and provides accurate bandwidth and L7 DPI reporting. Any collector that supports their enterprise elements should be accurate. As far as I know, Plixer is the only one with full support... This is the case with many IPFIX exports from other vendors as well. Full disclosure, I work for Plixer. If you have any questions, call Plixer and ask for me "mike k" and I'd be happy to go over it.

Neither of the two for enterprices
My experience with DDOS attacks so far is that the detection of SFLOW or NetFlow + the time to redirect the traffic to a cloud based solution is way too long for the environment to sustain, making the DDOS effective immediatly.


To me an inline DDOS solution that can inspect each and every packet up to the max. bandwidth of the environment is a much better solution. This is fast (< 5 sec. detection and blocking). When the attack becomes bigger then you can think of redirection of traffic into the cloud for mitigation over there. Some DDOS cloud providers now offer API's for on-premise DDOS boxes to send them an alert. Then they can start the redirection of traffic towards the cloud.

My believe this is the way forward for Enterprises and smaller ISP's to move forward. For bigger ISP's and Carriers I guess the above story is true.
