"ODBC" isn't a "port set"; it's an application protocol. What "ports" are they requesting? You're correct; ISA doesn't "see" SQL connections like it does HTTP, so "application-layer-filtering" isn't going to be a reality. - Don't give them a Win acct; limit the potential for damage to the databases. - Limit the access for that SQL acct to ONLY the DB they need to destroy. - enable logging for every breath they take on that SQL server; it's yours, not theirs Jim Harrison MCP(NT4, W2K), A+, Network+, PCG http://isaserver.org/Jim_Harrison/ http://isatools.org Read the help / books / articles! -----Original Message----- From: Greg Hess [mailto:gmh@xxxxxxxx] Sent: Friday, November 19, 2004 6:15 AM To: [ISAserver.org Discussion List] Subject: [isalist] ODBC from vendor network http://www.ISAserver.org Good morning, I have a vendor who wants to connect to our network for some 'real time' data. I want to firewall them off (obviously), but for this application to work they want to have ODBC through the firewall to our SQL server 2000. This makes me nervous in the number of ports they need, and that they are using NAT on their routers, so I don't think stateful inspection will save me from any vicious attacks. Did I add they need to use SQL server logon instead of Win2k? Has anyone had to do this, and if so, how did you secure it? Thank you in advance on this Friday Greg. ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=isalist ISA Server Newsletter: http://www.isaserver.org/pages/newsletter.asp ISA Server FAQ: http://www.isaserver.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: World of Windows Networking: http://www.windowsnetworking.com Leading Network Software Directory: http://www.serverfiles.com No.1 Exchange Server Resource Site: http://www.msexchange.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: jim@xxxxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=isalist Report abuse to listadmin@xxxxxxxxxxxxx All mail to and from this domain is GFI-scanned.
