Week 5- Case Studies
American Intercontinental University
October , 2011
This paper will discuss the questions asked about the four different case studies we are to read this week. The case studies are When antivirus software cripples your computers, How secure is the cloud, Are electronic medical records a cure for heath care, and JetBlue and WestJet: A tale of two IS projects (Laudon & Laudon, 2012, pgs 304, 321, 522 & 556).
WEEK 5 CASE STUDIES
WHEN ANTIVIRUS SOFTWARE CRIPPLES YOUR COMPUTERS
There are a few reasons why McAfee’s antivirus software created so many problems for their users. First, when test simulations were done, management did not run these tests for Windows XP, with service pack 3, users using the McAfee VirusScan version 8.7 (Laudon & Laudon, 2012, p. 304). Most McAfee users of VirusScan were using Windows XP service pack 3 and the VirusScan version 8.7, these were the individuals most affected by this faulty update download. The update for VirusScan was intended to deal with the new virus ‘W32/wecorl.a’. However, it was not known that this virus could make itself appear as the name svchost.exe, which is a Windows file that is critical to PC’s performance (Laudon & Laudon, 2012, p. 304). It was also the slipup of the company to not detect this problem sooner. There was such a high demand for faster antivirus updates that lead to this slipup.
The impact on the company, because of this software malfunction, was very damaging to the company. Their reputation with their customers was damaged, but it is not stated how bad it was or if McAfee lost customers or revenue. The impact on their customers, however, was very bad. Customer’s computers would not boot up properly and they were not able to access files or networks. Once there was a resolution to fix the problem, each computer had to be accessed one by one. Another big problem McAfee encountered was that they tried to downplay the impact of their customers (Laudon & Laudon, 2012, p. 304-305).
If I were a McAfee customer, I would not have accepted their response for the problem. First, McAfee did not do enough research and testing, and failed to test one of the most popularly used operating systems with the new version of VirusScan. This was not very professional of them. Then they did not respond to customers in a timely manner. Customers did not know what was happening or how to fix it. McAfee should have immediately put out an explanation and an apology for the inconvenience. They did do this, but it was not done until after the problem had gotten worse.
In order to prevent instances like this from happening again McAfee should make sure all tests done are performed using most up to date operating systems, as well as older systems, with the various versions of the antivirus software that is being used by customers. I am sure McAfee has numerous ways of getting information on how many customers are using which versions of their software. They can also put out warnings for those customers using older versions that their systems could be affected by new updates. This would insure that customers had access to such information, and McAfee could not be held responsible for any problems with customer systems. It is all a matter of research, testing, and knowledge about their software. HOW SECURE IS THE CLOUD
One of the security and control problems discussed in this case study about the cloud is that the computing of the system is “highly distributed” (Laudon & Laudon, 2012, p. 321). All applications and data within the cloud systems are stored in virtual libraries. It is often hard to determine where your data is being hosted. Providers store and distribute data and work in data centers all over the world (Laudon & Laudon, 2012, p. 321). Another risk of this kind of distribution is the difficulty to “track unauthorized activity” (Laudon &...
