Mini-Case 1: Belmont State Bank – Chapter 11

Risk Assessment

Belmont State Bank, with their current computer system is virtually wide open for an attack from external or internal sources because of their password requirements. That is the first thing that jumped out when reading the scenario. This is probably the easiest type of password there is to crack. And if not the easiest, it is certainly one of the easiest. It would probably take less than one minute for even an inexperienced hacker to crack a four (4) digit numeric password. Belmont State Bank should require at least a 6 to 8 digit password containing upper-case and lower-case letters, at least 1 number, and at least 1 special character. (Vanin, 2012)

In today’s security processes it either requires excessive time in terms of hours to download the updates provided by AV vendors. It is much more difficult to have an effective firewall in place because the dial-up services are very unlikely to be routed through a router.

    Between every network and the outside host of threats there is a first line of defense. For almost every network this will be a firewall. A firewall can be both hardware and software and is usually a combination of the two. A firewall creates a barrier between networks. Any outside computer or client must pass through the firewall to access the network or its resources. Only a computer or system that has proper access can easily access a network protected by a properly configured firewall. Though it is not infallible, a firewall is the first and perhaps best means of security…

    Cas 1) The substance-over-form concept is explained by accountingtools.com as a concept in which “the information shown in the financial statements and accompanying disclosures of a business should reflect the underlying realities of accounting transactions, rather than the legal form in which they appear.” They go on to explain that the main point of the concept is that “a transaction should not be recorded in such a manner as to hide the true intent of the transaction.” The concept requires or assumes that someone is attempting to deliberately hide a transaction as one that meets GAAP standards although in reality the transaction would affect the financial statements differently than reported. This form of deceit was used over and over by Lincoln S&L. The biggest example provided was on page 87 concerning the “Hidden Valley” transaction.…
