Case Study

  
Case Study
Do a case analysis of any one of the cases presented in Chapter 6 in the textbook (Chapple et. al.),( pages attached)Make certain that your report covers all the major elements of the case. You should indicate clearly which case you have analyzed, the Private Sector, the Public Sector or the Critical Infrastructure.
 Make sure to follow APA style. Please make sure your submission is 2 – 3 pages in length and meet the minimum APA formatting guidelines:
 
•    12-pt, Times New Roman font
•    Double-spaced
•    1” margins on all sides
•    Please provide a title page including your Name, Course Number, Date of Submission, and Assignment name.
•    Paraphrasing of content – Demonstrate that you understand the case by summarizing the case in your own words. Direct quotes should be used minimally.
•    Reference Section (A separate page is recommended.) Please cite the source using APA formatting guidelines. If you need guidance or a refresher on this, please visit: https://owl.english.purdue.edu/owl/resource/560/10/ (link is external) Be sure to include at least three reference sources.

Private Sector Case Study
Cloud Collaboration is a large new media company that has recently
launched a Software as a Service (SaaS) office suite. This suite includes a
word processor, as well as presentation, e-mail, calendar, and spreadsheet
applications. Also included are collaboration and Web authoring tools.
SaaS is a model of software distribution that hosts software in a cloud-based
environment on a subscription basis. Instead of simply selling an application,
a SaaS vendor offers access to the applications for a small subscription fee.
The application and data are stored on the vendor’s servers and the customer
accesses them remotely. This benefits the customer by lowering operating
costs, and adding security and portability. SaaS sometimes costs less, both in
upfront and ongoing costs, than buying software in a traditional manner. This
is especially true for a small-business environment that may not have the
capital necessary for the hardware associated with large centralized
applications.
SaaS also adds a new layer of document security; even if a workstation is
physically stolen, the information is safe because all of the documents are
stored on the vendor’s servers instead of the customer’s workstation. Storing
the information remotely also gives the customer an amazing amount of
portability. Any system with appropriate access software can access the data.
In Cloud Collaboration’s case, the office suite is Web-based, so any system
with a Web browser can be used to access the applications
Public Sector Case Study
The U.S. military needed a way to communicate information quickly and
securely in the rapidly changing environment of a battlefield. Wired
communications, while secure and robust, had significant drawbacks.
Communication lines could easily be severed, and military personnel were
limited to communicating only at fixed locations. Radio and wireless
communications removed the threat of cut lines and extended the range of
communications, allowing military personnel to communicate with mobile
units, but only to a fixed range. Stationary installations were still needed as
base stations, and throughput degraded the farther the units were from the
base station. That led the military to turn to a new type of wireless
networking called wireless mesh networking.
Wireless mesh networks are based on a distributed network mesh topology.
Each node in the network connects to multiple nodes. Each node also acts as
a router for the nodes it connects to, allowing traffic to hop along multiple
paths to a destination. This allows for a very robust and flexible network. The
loss of one node will not hurt the network, and nodes can be added at will.
Range of the total network is also massive because nodes don’t need to be
close to a central point. They need just one other node to function. An
example of a mesh network can be seen in Figure 6-2.

Critical Infrastructure Case Study
Power plants are an important part of critical infrastructure and local, state,
and national economies. Therefore, power plants need deep and multilayered
access controls due to concerns over physical security. There are a number of
sensitive areas that must be secured, and various employees need different
levels of access to these locations. At a plant in the upper Midwest, this
access is handled with identity badges that include images of the user and an
RFID with the user’s access rights.
The RFID handles access through multiple levels. There is a security
checkpoint at the entrance to the parking lot and at the entrance to the
building. Both points require a badge to enter. From there, the badge allows
personnel to enter the facilities they are authorized to enter. It also acts as
“something you have” for multipoint authentication onto secure systems.
