There is a product that communicates to the event viewer and displays events via an agent that, which you connect to via an HTPPS session in browser. The product is known as snare for windows, created by Intersect Alliance. This product can also be pointed to a syslog server like Kiwi or whatever your flavor... -----Original Message----- From: listbounce@securityfocus.com [mailto:listbounce@securityfocus.com] On Behalf Of Bhardwaj, Akash Sent: Thursday, September 27, 2007 7:27 AM To: Petter Bruland; gjgowey@tmo.blackberry.net; Jim Mellander Cc: listbounce@securityfocus.com; itsec.info; security-basics@securityfocus.com Subject: RE: Routing protocols, Internet vs Enterprises I have several Windows OS servers and looking for a freeware/open source application that can show me all the Event Viewer logs via a web site.

That is one thing I really appreciate about this list, so thanks for lots of good postings. ** Maybe I can sneak a question in here, and see if it get noticed or maybe even answered ;-) In a Windows 2003 Active Directory "network", is there a way to turn on audit to the point where you would be able to find out what end device locked out an account? I've dug around and I'm not able to get any useful information out of the security audit log/event viewer... Thanks again. -Petter -----Original Message----- From: gjgowey@tmo.blackberry.net [mailto:gjgowey@tmo.blackberry.net] Sent: Wednesday, September 26, 2007 4:10 PM To: Jim Mellander Cc: Petter Bruland; listbounce@securityfocus.com; itsec.info; security-basics@securityfocus.com Subject: Re: Routing protocols, Internet vs Enterprises I used to be able to go one better. I had a fluke optiview just sitting on the network attached to a gig port with all the snmp community strings for the switches and routers in it. If someone did something stupid I could trace down to what port of what switch they were sitting on and just shut it off.

With companies one of the first questions that I think some people
forget to ask is if a routing protocol is really necessary for the network topology that they have. Routing protocols are only really useful for when you have multiple paths out of your particular subnet. If you only have one path out then using any routing protocol is needless.
That may seem like common sense, but I used to work for one large
employer who, because the network admins weren't too bright about routing, used ospf on every router they had to link all their buildings. Even though each router only had a single T1 connecting it directly to the core router at the noc and that router had a direct 10/100 link to the upstream providers router. I'd tell more, but I think some people here would think I was bullshitting.

Even in a situation as you describe, using a routing protocol is not entirely without benefit. For instance, suppose a miscreant host is spewing spam to the internal network, and the internet. We could log into the router closest to the host and put a host-level null route in place, thus confining the hosts miscreant activity to its broadcast domain. If a routing protocol (OSPF, even RIP) is in place, the routing update can be made to a central router, which will then propagate it - which would likely make such activities easier to script, and manage. -- Jim Mellander Incident Response Manager Computer Protection Program Lawrence Berkeley National Laboratory (510) 486-7204 The reason you are having computer problems is: Did you pay the new Support Fee? ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.
