Your recommendation is in tune with best practices. In addition, you need to
educate the decision makers on internal FW, ACLs and network segmentation
utilizing VLANS in addition to policy enforcement as this sort of things are
already defined within IT policies but never conformed to due to the
ignorance of administrators. You need to point out the risks to the decision
makers that for an Application or network to be secured, its not a matter of
doing or implementing one thing even when application coding best practices
are followed, it must be an embedded integrated layered effort including
systems hardening and general administrator awareness in addition to
following procedures of change management and systems certification process.
Hope this is helpful.
Thanks,
Michael

Subject: Bank Audit Best practices
I'm looking for some feedback from other people who conduct security
audits 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?
