Which control(s) would best mitigate the following threats?
Which control(s) would best mitigate the following threats?
Threats Control(s)
a. The hours worked field in a payroll
transaction record contained the value 400
instead of 40. As a result, the employee received
a paycheck for $6,257.24 instead of $654.32.
b. The accounts receivable file was destroyed
because it was accidentally used to update
accounts payable.
c. During processing of customer payments, the
digit 0 in a payment of $204 was mistakenly
typed as the letter “O.” As a result, the
transaction was not processed correctly and the
customer erroneously received a letter that the
account was delinquent.
d. A salesperson mistakenly entered an online
order for 50 laser printers instead of 50 laser
printer toner cartridges.
e. A 20-minute power brownout caused a
mission-critical database server to crash,
shutting down operations temporarily.
f. A fire destroyed the data center, including all
backup copies of the accounts receivable files.
g. After processing sales transactions, the
inventory report showed a negative quantity on
hand for several items.
h. A customer order for an important part did
not include the customer’s address.
Consequently, the order was not shipped on
time and the customer called to complain.
i. When entering a large credit sale, the clerk
typed in the customer’s account number as
45982 instead of 45892. That account number
did not exist. The mistake was not caught until
later in the week when the weekly billing
process was run. Consequently, the customer
was not billed for another week, delaying
receipt of payment.
j. A visitor to the company’s Web site entered
400 characters into the five-digit Zip code field,
causing the server to crash.
k. Two traveling sales representatives accessed
the parts database at the same time.
Salesperson A noted that there were still 55
units of part 723 available and entered an order
for 45 of them. While salesperson A was keying
in the order, salesperson B, in another state,
also noted the availability of 55 units for part
723 and entered an order for 33 of them. Both
sales reps promised their customer next-day
delivery. Salesperson A’s customer, however,
learned the next day that the part would have to
be back-ordered. The customer canceled the
sale and vowed to never again do business with
the company.
l. The warranty department manager was upset
because special discount coupons were mailed
to every customer who had purchased the
product within the past 3 years, instead of to
only those customers who had purchased the
product within the past 3 months.
m. The clerk entering details about a large
credit sale mistakenly typed in a nonexistent
account number. Consequently, the company
never received payment for the items.
n. A customer filled in the wrong account
number on the portion of the invoice being
returned with payment. Consequently, the
payment was credited to another customer’s
account.
o. A batch of 73 time sheets was sent to the
payroll department for weekly processing.
Somehow, one of the time sheets did not get
processed. The mistake was not caught until
payday, when one employee complained about
not receiving a paycheck.
p. Sunspot activity resulted in the loss of some
data being sent to the regional office. The
problem was not discovered until several days
later when managers attempted to query the
database for that information
