Risk assessment
Below is the Global Finance, Inc. (GFI)
network diagram. A hypothetical company, GFI has grown rapidly this past year
and implemented a number of network devices as displayed in the diagram. The
company invested in the network and designed it to be fault tolerant and
resilient from any network failures. However, although the company’s financial
status has matured and its network has expanded at a rapid pace, its overall
network security posture has not kept up with the company growth.
GFI’s network has historically been fairly
stable, and the company has not experienced many full scale network outages.
GFI has hired three (3) network engineers to keep up with the network growth,
as well as the bandwidth demand by the company employees and the clients.
However, the company has not hired any security personnel who can take care of
the operational security responsibility.
The
trusted computing base (TCB) internal network within the Global Finance, Inc.
Network Diagram hosts the company’s mission critical systems that are vital to
the company’s operations that also affect the overall financial situation. The
Oracle database and email systems are among the most intensively used
application servers in the company. GFI cannot afford system or network
outages, as its cash flow and financial systems heavily depend on the network
stability and availability. GFI has experienced DoS network attacks twice this
year, and its Oracle database and email servers had been down for a total of
one (1) week as a result. The recovery process required GFI to utilize $25,000
to restore its operations to the normal operating baseline. GFI estimated the
loss from these network attacks at more than $1,000,000, as well as lost
customer confidence.
Write an eight to ten (8-10) page formal
risk assessment proposal in which you:
1.Describe the company network,
interconnection, and communication environment.
2.Assess risk based on the GFI, Inc.
network diagram scenario. Note: Your risk assessment should cover all the
necessary details for your client, GFI Inc., to understand the risk factors of
the organization and risk posture of the current environment. The company
management will utilize this risk assessment to determine what actions to take;
therefore, it must be comprehensive for the business leaders to make
data-driven decisions.1.Defend your assumptions where pertinent information
from the scenario isn’t available.2.Ascertain apparent security
vulnerabilities, and analyze at least three (3) such vulnerabilities. Such
analysis should entertain the possibility of faulty network design. Recommend
mitigation processes and procedures for each of the identified vulnerabilities.
3.Justify your cryptography recommendations,
based on security concerns and requirements, data-driven decision-making, and
objective opinions.
3.Examine whether your risk assessment
methodology is quantitative, qualitative, or a combination of these, and
discuss the main reasons why you believe that the methodology that you utilized
was the most appropriate.
4.Explain the way in which you would
present your findings and assessment to the company’s management and thus
facilitate security buy-in and concentration.
5.Using Microsoft Visio or its open source
equivalent, redraw the CFI diagram, depicted as a secure and risk-mitigating
model. Note: The graphically depicted solution is not included in the required
page length.
6.Use at least three (3) quality resources
in this assignment. Note: Wikipedia and similar Websites do not qualify as
quality resources.
Your
assignment must follow these formatting requirements:
•Be typed, double spaced, using Times New
Roman font (size 12), with one-inch margins on all sides; citations and

•Include a cover page containing the title
of the assignment, the student’s name, the professor’s name, the course title,
and the date. The cover page and the reference page are not included in the
required assignment page length.
•Include charts or diagrams created in
Visio or an open source alternative such as Dia. The completed diagrams /
charts must be imported into the Word document before the paper is submitted.
The specific course learning outcomes
associated with this assignment are:
•Evaluate an organization’s security
policies and risk management procedures, and its ability to provide security
countermeasures.
•Analyze the methods of managing,
controlling, and mitigating security risks and vulnerabilities.
•Explain access control methods and
attacks.
•Describe the details and the importance of
application security models and their implementation from a management
perspective.
•Evaluate and explain from a management
perspective the industry-standard equipment, tools, and technologies organizations
can employ to mitigate risks and thwart both internal and external attacks.
•Use technology and information resources
to research issues in security management.
•Write clearly and concisely about the
theories of security management using proper writing mechanics and technical
style conventions.
