I've run into it a lot, and I have the same concerns you do. Core Processors *should* be restricted especially if they do not provide any type of reports of their own internal security audits. Usually we ask the client to see if the core processor has done any assessments and if so give the client (the bank) the report, or at least parts of it. Usually the processor really only needs access to the teller machines and any other hosts doing general ledger. (I usually see this just being an FTP server.) Other than those hosts, I do not see any need for the processor to have any extended access. The client needs to identify what hosts/servers require this access and by either firewalling or strict ACL's (VLAN's are good) limit the access given. This really shouldn't be a problem as the Core Processor shouldn't ever notice these changes. -wireOn Wed, 17 Mar 2004 09:06:34 -0500

I'm looking for some feedback from other people who conduct securityaudits and penetration tests on banks.One of the network aspects I come across a lot is a direct line to their transaction processor. This is often in the form of a point-to-point or frame line that is dropped onsite with a router controlled by the processor, not the bank. I always point out that this is a network security risk, as there is no control from the bank side regarding the access provided through that line, and recommend an ACL or departmental firewall at that point. As always, the administrators look at me like I recommended them selling their firstborn. The relationship between the bank and their processor is very symbiotic as the bank couldn't even exist without their services, yet my perspective is any outside system should go through some level of border security in order to monitor and restrict traffic. Anyone run into this? How do you handle? M.
