Deepali,
Great example! I absolutely agree with you that there should be strong controls implemented to prevent terminated employees from accessing the organization VPN. Several days ago, I had a chance to talk to a Cyber Security professional. And he even mentioned that not many companies have proper procedures to deactivate terminated…[Read more]

Abhay,
Thank you for pointing it out! You are correct. The transport layer should oversee the process of data transfer in respect to transparency and reliability as you said. In this phase of OSI model, flow control is very important. You don’t want to see broken data or missing data in the end of receiving them.

Binu,
I also agree with you. The speed is definitely depending on the internet providers if you are using the internet-based VPN. VPN is heavily used for the purpose of working remotely while connected to the organizations/companies network. Speed can’t be matched up to the local/physical lines; however, many organizations/companies are…[Read more]

Priya,
You are absolutely right. When using the internet-based VPN, the shortcoming you should expect is you no longer have an absolute control on the connectivity of the internet. That is, if the internet providers’ server is down, your VPN will be also disconnected because your VPN is highly depending on the providers’ systems.

Binu,
Thank you for your comment! In my opinion, the second control I mentioned could be possibly preventing a person from committing a fraud. For example, like a real life scenario, you know there is always a police car on the entrance of the highway you are taking to go to work all the time. Then, you would not tend to or not at all speed up…[Read more]

Paul,
Thank you for bring up the concept of the collusion. I absolutely agree with you that Mr. Cash was not able to get away from internal controls (if there were any) for a long time without a help of other employees. He had been dragging the parts from the assembly lines over a long period of time, and in the end, he wasn’t caught and built…[Read more]

Rightly pointed out Deepali. Organizations/companies always count on the ROI factor. Even though you have implemented the world greatest security system by investing a lot of money, if you are not making any profits over your investment on the security system, it is worth nothing. For the security perspective, it is hard to measure the ROI because…[Read more]

Brou,
Great point. ‘Connection’ is always an important fact to consider when it comes to a crime. Personally, I have a great example of how people utilize a connection to commit a crime. When I was working for a grocery store, there was an incident happened that one employee was dragging out fruits our of the store. He has a connection in the…[Read more]

Q2. Assume the ‘One Piece at a Time’ video scenario could happen. If you are the operations manager responsible for the assembly line, what 1-2 key controls would you implement? Explain how the control addresses the risk.
If I were the operations manager responsible or the assembly line, I would implement two specific controls to pre…[Read more]

Q1. 1. Using the Fraud Triangle analyze the ‘One Piece at a Time’ video scenario and explain how the environment was favorable to Fraud.
Pressure – This is what motivates Mr. Cash to commit the crime at the first place. His motivations to taking the parts of Cadillac piece by piece from the assembly line were his desire to drive around in style…[Read more]

The OSI Model = the Open Systems Interconnection Model
7 Layers of the OSI Medel:
1. Physical (Layer 1) – OSI Model, Layer 1 conveys the bit stream – electrical impulse, light or radio signal – through the network at the electrical and mechanical level.

Ian,
I really like your explanation. You are absolutely right that Windows and Linux for example, are different managers that have totally different managing styles. And personally, if he/she gets comfortable with either one, he/she tends to continue using the one he/she choose at the beginning because there are a lot of switching costs he/she…[Read more]

Thank you for the information! Yes I’ve also heard of that Android is very vulnerable in terms of a virus protection. As an Android user, I always need to clean my phone once in a while because somehow another it gets viruses or malware all the time. And also I need to admit it that I sometimes let my phone connect to public wifi. Public…[Read more]

Magaly,
Rightly said, We need to enjoy using Operating Systems since they are existing for making our tasks in which related with any type of computer technology easier. In today’s nature of corporate America, technology takes a huge part of every business. And OSs are absolutely the key players to operate those technology systems.

Ian,
One example of the administrative policies that I can think of is the authorization controls. For example, in the Windows operating system, you can create accounts and allocate gradual accesses to those accounts by which actions or authorities you want to give to each account.

Paul,
Great assessment on responsibility for the controls of that company’s Order to Cash process. I also agree with you that COO and CFO are two main characters that have significant responsibility for company’s Order to Cash process. I really believe both COO and CFO are equally contributing to OTC process because if either one of them is not…[Read more]

Really good point. Human errors are the all-time enemy like we’ve been discussing this in previous week questions. The most effective solution to minimize the human error is making every process automated. And we’ve seen more and more automated technology in the phase of delivery these days. For example, Amazon is trying to utilize drones…[Read more]

Mansi,
Rightly said. Managing customers master data is a very important portion of the order to cash process. One simple mistake, putting a wrong address for example, can cause an unnecessary time to correct the order process. That is why the current order to cash systems are becoming more automated. We know that less human involvement results…[Read more]
