Nuno-
I noticed in your email you spoke of a lack of centralized
management/correlation, and real-time monitoring in Dragon. I apologize if
you are not that familiar with the product, but there is such functionality.
Please see the following link for more information about the Server side of
Dragon.
http://www.securitywizards.com/server-fb.html
Also, I have included the intro to a great article below your email in which
the author tested several IDSes. He specifically addresses the speed of
Dragon Sensor and the scalability and management of the Dragon Server. It is
by Dragos Ruiu <dr
dursec.com>. You might what to track down the whole
article and read it.
As for real-time monitoring, Dragon Console is a component of the server
which allows for this. I have several customers with the console up in their
NOC and it has served them quite well.
If you have any questions about any of the above mentioned products, please
feel free to contact me at any time.
Sincerely-
Gary

Subject: Re: Staffing an Intrusion Detection Capability?
Hi,
Ron I noticed your email is enterasys.com. You guys sell Dragon IDS. I
find it interesting you are asking a question like this. As for staffing,
security personal come in all shape and sizes. It's up to the organization
to fill a spectrum skill set in that group. Most products work well on there
own and have no need to have a full dedicated person monitoring it. They
even have managed server to were all NIDS and or HIDS report to.
P.S. Can you guys please add that to your product, that is one thing it
lacks is real-time monitoring.
