Network for a bank and its branches

By serge.bianda ·
Hello,
I am a network administrator for a small private corporate and recently I have been contracted by another company to design (from scratch)a new network architecture for a banking institution with 3 branches which all need to be connected asa WAN. Any suggestion on what is needed (hardware, software,..)for a bank in particular as I have never dealt with a banking system in terms of networking. I know one thing is that the security should be the #1 concern. Thanks

Just like in any network you will need to determine system requirements. How many users at each site? What apps do they run? What files do they need? How much bandwidth will this require? What are the server requirements? Is this for internal use only, or is this system for customer use (online banking)? What (if any) Internet access is needed? Remote access?

Answer these types of questions and you should have a good idea as far as hardware, software, and connectivity. You still need to address what appears to be the number one priority, which is security. User authentication, password policy, and user training should be at the top of the list. Make sure passwords are encyrpted and not sent in clear text. (The specifics willrely on what O/S you decide.) Look into establishing a PKI (Public Key Infrastructure.) For the WAN, you might consider direct connections and leased lines as well as VPN's.

But again, the most important thing is to define your system requirements. The customer should be very much involved here. Show them the costs, benefits, and risks of any level of security, and make sure they understand the final decision (and the responsibility) is thiers. :)

Well first of all you have to decide on how fast you want your wide area network to be from dial-up to fiber. The cheapest would be dial up but my recommendation is as follows. Either have Fiber or T-1 line to connect back to your main office. If you do not have that many users at your remote locations say no more than 5 then use ISDN if you have more than that T-1 but the best solution would be a Fiber lease with 100mb or 1000/mb cards in your switches for bandwidth. They are pretty easy to configure and most of the time if you are leasing a line from the Phone company they will setup your T-1 line and CSU/DSU for you and all you have to do is plug it into your switch via patch cord. The cheapest but with desent speed is going to be a T-1 line. Also I would switch everything so that you have a switched network vs. just repeaters. That away you have far less traffic on your network. Also you can sub-net out your network depending on the size the most common subnetting for a class be is for example 172.17.0.0/24 that away it subnets everything down to a class C. Keep in mind the 172.17.0.1-254 and 172.17.255-254 will not be able to be used when you subnet out your network this way but if you just have a class C itself then depending on how many users you have your could subnet it out as well. But if you are pushing 200 total users on your network it would not be a good idea to do this. Because when you subnet you loose IP's. Use TCP-IP as your protocol and your lans set themup the same way as usuall and you should be fine. If you have any other questions just email me as wroming@ci.killeen.tx.us . Have a great day and weekend.
