Case Study: We Need an Intranet!

Mary Kate is a project manager in the IT department for a university. She has been asked to manage a project to create a faculty intranet. The university has multiple campuses in various locations, and professors and other faculty need to be able to easily post questions, schedules and other documents to share in a secure environment.

Mary Kate performed the following steps to begin the intranet project.

She performed a needs analysis. Mary Kate interviewed the university faculty to determine their needs for an intranet and the uses they foresee for it. She discovered that several of the professors were working on a research project and wanted to use the intranet to facilitate group discussions, as well as to host periodic Webinars for professors at other universities.

She chose the project team. Mary Kate enlisted members of the IT department for the project, including someone to install firewalls so users have more secure access to the Internet, and someone to set up the site to host Webinars.

She determined the project constraints. Mary Kate determined when the intranet needed to be live. She considered how long she would have the services of the various team members, how long team members could work on this project before being assigned to other tasks, and when the first Webinar was scheduled. Once she gathered all of this information, she was able to determine the project scope and constraints.

She created the project schedule. Mary Kate worked with the project team to outline the tasks and task relationships required to complete the project. She assigned resources to specific tasks so that each person was aware of his or her role in the overall project plan.

She scheduled weekly meetings for the duration of the project. Mary Kate included the CIO, project team members, faculty members and all other stakeholders in the meetings.

She created a project status report and an issues log. Mary Kate used these documents in each meeting to apprise stakeholders of the project's progress and to introduce any problems or issues that had arisen since the last meeting.Once Mary Kate had performed all these tasks, she was ready to begin the executing phase of the project.

As a class, discuss this scenario and answer the following questions.

Which steps already performed by Mary Kate are part of the initiating phase for this project? Which steps are part of the planning phase?

Has Mary Kate overlooked any steps in the first two phases of this project?
What other tasks might she need to perform?

What tasks might Mary Kate perform in the executing phase? In the controlling phase? In the closing phase?

How might scope creep occur in this project? How could it be managed?

Case Study: These Are Sensitive Files

The contracts manager at a company needs to make a large legal document available to an overseas customer. However, she has some challenges: The document contains sensitive information; it is too large to send via e-mail; and the manager is expecting an amended document in return.

The contracts manager must make the document available in electronic format to only herself and the customer.

First, the contracts manager sets up an FTP account that requires user names and passwords. She gives these user names and passwords to the customer and instructs him not to divulge the account information to anyone. She reveals authentication information to the customer only across a secure channel (or in person).

Next, the contracts manager sets up a folder on the company FTP site into which she can upload the sensitive document. She ensures that only users with specific permissions can access the folder.

The contracts manager now gives the customer permissions to upload and download files to and from this folder.

As a class, consider this scenario and answer the following questions:

The information in this document is extremely sensitive. Suppose someone might try to gain access by "sniffing" the FTP passwords during authentication. How could the contracts manager further secure this file? Could she use S/FTP to secure the file? Could she use FTPS?

Consider some of the other Internet services discussed in this lesson. Which ones would be inappropriate for transmitting this file? Why?

Case Study: To Be Valid or Not to Be Valid?

Ellen is an anthropologist who has been working at Olduvai Gorge in Tanzania for the past six months. She has been conducting research on the Internet. She finds a Web site with an article that proposes a revolutionary theory regarding human migration patterns from east-central Africa that may have occurred about 150,000 years ago. Ellen wants to determine whether the information is valid before she presents it to her fellow anthropologists for consideration.

Ellen performs the following tasks:

·         She obtains information about the organization on whose Web site the article was presented. Based on the domain name, Ellen determines that the organization is an educational institution.

·         She researches other organizations recommended by the Web site containing the article by following some of the links. She finds that the sites are hosted by trustworthy sources known in her field.

·         She checks the credentials of the author and determines that he is a known professional in anthropology who has published reputable works.

·         She accesses current scholarly writings and professional journals, and finds that this new and exciting theory has the support of other anthropologists.

Ellen feels comfortable presenting the information she found to her fellow anthropologists because she knows it is valid.

As a class, discuss this scenario and answer the following questions:

·         What other ways can Ellen evaluate the information presented in the article to determine its legitimacy?

·         Because various other resources have cited the theory, does Ellen still need to cite her source when sharing the information? Which source(s) should she cite?

·         Consider each of the tasks Ellen performed in the scenario. For each task, what might she have instead found that could have indicated the information was not valid?

Opt-in e-mail marketing:  Registering a business's web site.

Opt-in mass texting services: used most often on mobile devices.

List Server:  Collects and distributes info.  server automates the collection and distribution of messages from an authorized group of participants.  Allowing collaboration amongst users.

File Transfer Protocal:  internet FTP servers include Large text files and Bianary Files:  a file containing data or instructions written in zero's and ones.  (computer language).

Managing downloaded files:

MIME type files:  Multipurpose Mail Extensions.  It's a way of identifying files on the Internet according to their nature and format.

Compress files you want to send as e-mail attachments to reduce transfer times and to conserve space on the recipients hard drive.

Virtual Network Computing:   (VNC) allows you to control a computer remotely.

VNC consists of 2 components:

1. Server: Listens on a specific port and allows clients to connect.

2.  Viewer: allows users to see the remote systems log on enviornment.

Peer to Peer Networks: Each server has cliet and server capabilites.  Allows a group of users to connect with each other and directly share files among Hardrives.  Inexpensive method....

Exp: BitTorrent: alows you to download  more than a gigabyte!

File Transfer Protocol (FTP) is a TCP/IP suite protocol that allows the transfer of files between two computers, or one server and one computer. FTP is a convenient way to transfer files and can be a good alternative to sending an e-mail attachment.

An FTP server can require user-based authentication. Requires the user to provide a user name and a password.

Remember that standard FTP does not encrypt the authentication session. Be careful what info you send!

FTP clients cannot change their own passwords. If a password must be changed, the user must contact the FTP administrator, who can change it.

FTP server contents
Two common types of resources available on Internet FTP servers:
Bianary file:  A file containing data or instructions written in zeros and ones (computer language)Binary files are executable files, small software applications, images that require an association to open, or compressed files that require decompression.
Large Text files:  The large text files are usually application source files. Programmers use these files to customize and compile programs.

FTP servers often contain popular shareware and open-source freeware. Shareware is inexpensive; you download it, and if you like it you send the vendor a payment. Freeware is free; it may be a beta version.

Large Text files, Bianary files: need to be compressed to sped up the process of downloading. Then need to be decompressed.

Two popular mass-marketing technologies used to push advertisements, promotions and emergency broadcasts:

Opt-in e-mail marketing — Opt-in e-mail marketing is used every day by companies and individuals alike. Often when you register at a business's Web site, such as Target.com, for example, you are asked if you would like to receive e-mails regarding special promotions or other types of updates. If you select "Yes," you have opted in and are added to an e-mail list server (list servers are discussed in the following section). Whenever Target has a promotion or a weekly advertisement they want to distribute, the e-mail server sends the promotional e-mail to everyone on the list. There can be hundreds or thousands of recipients.

Opt-in mass texting services — Opt-in texting services are similar, but are used most often on mobile devices. The service is technically a Short Message Service (SMS) used by phone carriers, not an Internet service, but it serves the same purpose as mass e-mail. If a user visits the Target Web site and sets up an account on his or her smartphone.

A list server is a server that automates the collection and distribution of messages from an authorized group of participants, allowing collaboration among multiple users. A list server differs from a mail server, which handles incoming and outgoing e-mail for Internet users. A group of users that subscribes to a mailing list is called a listserve group. Participants can send an e-mail to the list server to join a specific group, or be added upon registering for a service. Once subscribed, they are placed on a mailing list .

How traditional list servers work:
A user who wants to join a listserve group simply sends an e-mail message to the list server. This request is often a blank e-mail message with a simple request in the Subject field. A request can be worded as follows:
subscribe ciw

Three of the most popular list servers are:

LISTSERV (www.lsoft.com), which is a product of L-Soft.

Majordomo (www.greatcircle.com/majordomo), which is hosted by Great Circle Associates and is freeware.

Lyris (www.lyris.com).
