Case Study 1: Stuxnet
Due Week 2 and worth 60 points
In June 2010, Stuxnet, a complex and highly sophisticated computer
worm was discovered by Kaspersky Lab. Stuxnet targeted Siemens
industrial Supervisory Control and Data Acquisition (SCADA) systems.
It was reported that the worm appeared to target Iran’s uranium
enrichment infrastructure. Most computer worms and viruses tend to
target consumer systems such as desktop computers and laptop
computers.

CIS 560 Week 4 Case Study 2 Cisco’s Remote
Access (2 Papers)
Case Study 2: Cisco’s Remote Access

Go to Cisco’s Website and read, “How Cisco IT Provides Remote
Access for Small Offices and Teleworkers”, located at
http://bit.ly/MkvlbA. According to the study, an IDC forecast from
December 2007, expected the global mobile worker population to
increase from 758.6 million in 2006 to more than 1.0 billion in 2011.
Cisco had a significant number of telecommuting employees and faced
three challenges: provide network access features that cannot be
supported on a software VPN client, automate and simplify router
provisioning and updates, and enable a scalable VPN solution to
support up to 30,000 workers.
1. Evaluate the deployment cost savings realized by Cisco, and
determine if it was significant.
2. Analyze how the solution deployed by Cisco improved:
1. employee productivity
2. satisfaction
3. retention
1. Discuss how Cisco was able to achieve VPN scalability to support
thousands of users.
2. When thousands of employees telecommute and work in virtual
offices, there are benefits to the environment. Discuss the environmental
impact of the Cisco telecommuting and virtual offices solution.

CIS 560 Week 7 Assignment 2 Single Sign-On
Access (2 Papers)
Assignment 2: Single Sign-On Access

Some business and organizationalnetwork infrastructures consist of
multiple systems from the same or different vendors to provide, conduct,
process, and execute various business functions. Some employees must
access one or more of these systems using valid access credentials
(username and password). Logging in and out of each system whenever
access is desired can become a problem for most users. Businesses and
organizations have resorted to using Single Sign-On (SSO) for user
authentication and authorization.
1. Analyze at least five (5) problems experienced by employees in an
enterprise where Single Sign-On (SSO) has not been implemented.
2. Some businesses and organizationsuse Active Directory (AD) to
provide SSO access to the enterprise. Analyze the advantages and
disadvantages of using AD for SSO access.
3. Some businesses and organizationsuse Lightweight Directory Access
Protocol (LADP) to provide SSO access to the enterprise. Analyze the
advantages and disadvantages of using LADP for SSO access.
4. Compare and contrast a Kerberos-based SSO configuration to a
smart card based configuration in terms of:
1. configurability
2. established standards
3. implementation challenges
4. cost

CIS 560 Week 9 Assignment 3: Secure Encrypted
Communications (2 Papers)

Assignment 3: Secure Encrypted Communications

process of encrypting and decrypting data using a digital certificate.
Evaluate the advantages and disadvantages of using digital certificates.
Evaluate the challenges related to public and private key management
when using PKI.
Use at least three (3) quality resources in this assignment.

CIS 560 Week 10 Term Paper The Human
Element (2 Papers)
Term Paper: The Human Element
Human nature is the single greatest vulnerability in any control system
and cannot be ignored. Organizations should always take human
behavior into account when designing access plans and strategies.
Human beings can pose unintentionalthreats when they accidentally
delete data. Hackers may be motivated by financial data when they
attack a system or use social engineering skills to gain access to
restricted data. Consider human nature and organizationalbehavior in
this term paper.
Write an eight to ten (8-10) page paper in which you:
1. Propose five (5) techniques that organizations should apply to
mitigate the threats arising from human nature.
2. Evaluate the consequences of a poor hiring decision. Propose steps
that could be taken to prevent such bad decisions in the first place.
3. Examine what an organization could possibly learn when a policy is
implemented to observe personnel in an ongoing manner.

4. Propose five (5) best practices that you would use to handle human
nature and organizationalbehavior.
