Which controls would best mitigate the following threats?
1. Posting the amount of a sale to a customer account that does not exist.
2. A customer entering too many characters into the five-digit zip code while making an online purchase, causing the server to crash.
3. An intern’s pay rate was entered as $150 per hour, not $15 per hour.
4. Approving a customer order without the customer’s address so the order was not shipped on time.
5. Entering the contract number of a critical contract as 13688 instead of 16388, which is a serious mistake to the company.
