Abstract

Computer Security is an issue of strategic importance for all organizations, taking into account the fact that information systems have become an integral part of strategic planning for all major companies. Organizations need to take into account the key elements of computer security while planning their information systems strategy. This paper examines the key elements of the computer security. This paper also explores the findings of three articles dealing with computer security (Coffee, 2007; Johnston & Hale, 2007; Katz, 2000). The first article explores the basic elements of computer security and how organizations can address these elements of computer security (Coffee, 2007). The second article examines how organizations can address all these elements of computer security into a comprehensive security solution (Katz, 2000). The third article examines the issues related to managerial decision making in the context of computer and information security (Johnston & Hale, 2007).

Elements of Computer Security

Computer security refers to the protection given to automated information systems in order to protect their integrity, availability and confidentiality (Stallings et al., 2008). Computer security involves security of all the information system resources including hardware, software, firmware and telecommunications.

According to Katz (2000), the key elements of computer security include physical security, authentication, access control, encryption and management of resources. Physical security includes secure environment for storage of all the digital resource both hardware as well as software. Authentication is the assurance that the communicating entity is the one it claims to be (Stallings et al., 2008). There are ...

Information Security Reviews

Case Assignment
Revisit Bruce Schneier's presentation in Module 2. This time, please focus on his discussions on cost/benefit analysis.
Schneier, B. (2008). What are the implications of spying? CCTV interview with Bruce Schneier. Retrieved from https://www.youtube.com/watch?v=Ar67N94NYr0

If you don't have access to the presentation, then simply read his article mentioned in Module 2. The article is:

Schneier, Bruce. The Psychology of Security. http://www.schneier.com/essay-155.html

The following article provides an example how such a cost/benefit analysis is considered.

Schneier, Bruce. Security at What Cost? National ID System Is Not Worth The $23 Billion Price Tag. http://www.schneier.com/essay-207.html.

The following article uses some typical accounting measurements for economics of information security.

Gordon, L. A., & Richardson, R. (2004). The New Economics of Information Security. Optimize. April, 83-86. (Trident Online Library: ProQuest)

The following article recaps what we talked about perceptions of security. More importantly, it discusses how people generally do not perceive gains and costs equally. When you conduct a cost/benefit analysis of security, you should keep that in mind.

West, R. (2008). The psychology of security. Communications of the ACM, Apr, 51(4), 34-40.

Incentive Design
The economics of information security is not only about cost/benefit analysis of implementing a security measure. Another major topic in economics is mechanism design, which provides principles and methods (like game theory) to help design incentive-compatible mechanisms that ensure participants are better off behaving honestly than dishonestly. See the following article to get a peek:

The Economist. (2007) Intelligent Design. Oct 18th, 2007. http://www.economist.com/finance/displaystory.cfm?story_id=9988840

To know more about the three Nobel Prize winners in 2007 economics division, surf http://nobelprize.org/nobel_prizes/economics/laureates/2007/ and check them out.

It is not easy to understand the revelation principle or the incentive-compatible design. I introduce you the concepts here for the purpose of making you aware of such a method. It takes time to learn how to design a game (a mechanism) that every party is better off by being honest.

Well, on a lighter note. Interestingly, a movie called "Mad Money" tells a story of three female employees of the Federal Reserve Bank stealing money that is about to be shredded. It is not a movie that I recommend to watch a second time, but it is entertaining enough to watch once. The movie is also a fit for the educational purpose here. I suggest you watch it once when you get a chance during this term, and pay special attention to the human factors -- especially the incentives of the thieves and the Chief Security Officer.

Other Economics Issues as to Security
As a matter of fact, there are many aspects in applying economics to information security. The following article has mentioned a list of authors that research economics of information security and provided a brief overview of their research:

Anderson R. and Schneier B., (2005) Economics of Information Security, IEEE Security and Privacy 3 (1), 2005, pp. 12-13. (Retrieved May 19, 2008).

To know more in depth, you can choose to view the video (optional):

Simonyi Konferencia 2011 - Economics of Information Security and Privacy. Retrieved from http://www.youtube.com/watch?v=fSfH80DY6S4

You are probably overwhelmed now with all these economics. I hope you also have broadened your views on security and have said "wow" to yourself that now you hold a much broader view on security and how to approach it from economic perspective.

Please write a 4- to 6-page paper discussing what you have learned:

What are the economic considerations of information security and its management?

In preparing your paper, you need to discuss the following issues, and support with arguments and evidence:

What are the major economic considerations in information security and management?
Are these economic considerations serving their purposes?
Why do these economic measures help?
Discuss economic mechanisms that can improve information security and management.
Provide a comparative table of the economic measures that you discussed.
