Resource Selection and Summary of an Article on CoBIT and ITIL Differences

There are ten (10) tasks, one for each week:  the tasks are detailed below.  There is a table to complete each task.  Please fill in the information required.  An example of a completed task is below.  Note the first response is good – so aim for something like this.  The second response is not acceptable, so if you submit anything like it, you won’t pass the assignment!  The reasons?  Poor resource selection (Wikipedia), no Harvard reference and a block cut and paste from the site (no citation, no original content)

This resource is a blog entry discussing the differences between CoBIT and ITIL.  I chose this resource as there is a lot of confusion about the way in which ITSM is applied, and the distinction between the CoBIT and ITIL implementations is frequently unclear.  Ibaraki explains that CoBIT provides the governance and metric structures while ITIL delivers on the actual mechanics and “how-to” processes.  The author makes an interesting observation that it is wrong to simplify COBIT as providing the ‘why’ and ITIL providing the ‘how’ because both ITSM mechanisms have considerable overlap and both need to be used at the same time.  I found this article very useful in explaining the differences and similarities between these two aspects of ITSM.

This page talks about ITSM.  It says that IT service management (ITSM) refers to the entirety of activities – directed by policies, organized and structured in processes and supporting procedures – that are performed by an organization or part of an organization to plan, deliver, operate and control IT services offered to customers. It is thus concerned with the implementation of quality IT services that meet the needs of customers and is performed by the IT service provider through an appropriate mix of people, process and information technology.

Task The past decade has witnessed tremendous advances in computing, wired and wireless communication, and storage technologies. Discuss the main features and applications of two mass storage technologies namely: direct-attached storage and network-attached storage.

The article describes the applications of direct-attached storage (DAS) and network-attached storage (NAS) elaborately. Paulsen, the author of this article explains numerous functionalities and features of NAS and DAS. I find this article quite informative and it explains DAS and NAS’s major features. DAS is known to provide the basic functionalities. Any organisations can get cost-effective service with the help of DAS. Low maintenance is required for DAS as well. The IT infrastructures can be facilitated by the usage of DAS, any organisation those who want to enhance their growth within a short period must take up DAS.  DAS is applicable to small business. It is known to facilitate the low budget project.  Paulsen further illustrates that DAS also facilitates those projects that have very little IT support. However, there are certain drawbacks of DAS. DAS is not applicable to large business. The large business which needs growth within a short period of time will not be benefitted by the adaptation of DAS. The author of this article also explains about the Network-attached storage. NAS basically involves sharing of files over the internet. NAS, unlike DAS, is applicable to a business that has little IT support. The organisations those who want reliable, as well as a flexible storage system, must take up the NAS. As per Paulsen, NAS is best suited for SMPs. The large organisations those who want to scale up the business must adopt the NAS. NAS provides easy solutions and reliable solutions during system failure. There is a drawback of NAS. Network-attached storage is not capable to transfer data in large number. I find this article helpful in knowing the details of the DAS and NAS. I get to know where DAS can be used and where NAS can be used.

The article explains all the transport layer standards elaborately. I find this article informative. The article elaborates two major protocols and standards of TCP/IP and they are TCP and UDP. TCP stands for Transport Layer Protocol. TCP is basically connection-oriented. TCP establishes a link between the clients and server and then the message gets exchanged or transmitted between the server and the client. TCP is known to provide reliability and it ensures data transmission all the time. Data can get lost during transmission however that data can be recovered with the aid of the TCP. The sender sends data in a particular order, TCP ensures that the data will be received by the receivers in the same order the sender sends data. TCP is best suited for applications which need sequential delivery. The data gets transmitted in the form of the byte stream. TCP is relatively slow as it takes time to establish the link between the receiver and the sender. The header size of TCP is near about 20 bytes. HTTP and HTTPs are some of the examples of TCP. The author explains UDP in details in the article. UDP stands for User Datagram Protocol. UDP is connectionless protocol. UDP connection is best-suited multicast message distribution. UDP connection is not reliable. Also, it does not provide a delivery guarantee. The data packets are transferred individually and each of the packets is checked for integrity. UDP is faster in comparison to UDP.  8 bytes is the header size for UDP. NFS, DHCP, TFTP and DNS are some of the examples of UDP. This article helps me in knowing the transport layer standards elaborately.

The article explains all the ill effects of a cyber attack in the health sector. I find this article relevant and it includes the cybersecurity challenges that are faced by health sector in IoT era. There are multiple security threats related to the health sector. The malware attack can prove to be disastrous for the healthcare units and hospital management system. The intruders attack the system of the health sector and steal all the confidential data of the patients and the employees and then ask for money. The health sector staffs if agrees to pay the money then they get their files back. Denial of Service attack is one of malicious attack that affects the health sector. The hackers take advantage of the insecure network and make the entire system vulnerable. In this way, the confidential data of the clients and the customers get compromised. the hospital management staff and the health sector must create a security system to protect the patient’s data, the financials of the health sector and the employees’ details. The health sector team must implement make their network secure, must install an antivirus program. All the employees must set up a strong password to secure their system. If possible they must set up a two-step verification procedure. The employees do not follow the procedures and become victims. IoT devices are used in the health sector. The IoT thermo-meter used in the health sector records the breathing sound of the patients. The IoT devices then store the diagnosis result on the server. The security attack on IoT devices can provide faulty data and results. The hackers even delete the results from the server. For this reason, the doctors cannot diagnose the illness of the patients well and entire health sector unit suffers. I find this article helpful in explaining the cybersecurity risks that can negatively affect the health sector.
