Part 1: Critical Thinking
- Acceptable-Use Internet Policies
Most schools have drafted acceptable-use policies for computers and Internet access to inform students and employees of the approved uses of college computing assets. Consider the following areas of a potential college policy:
- Should employees be allowed to use their computers and Internet access for personal tasks (such as checking personal e-mail or accessing Facebook)? If so, how much time per day is reasonable for employees to spend on personal tasks?
- Should student computer and Internet usage be monitored to ensure compliance with the personal use policies? Should the college inform students that they’re being monitored? What should the penalties be for violating these policies?
Most students will agree that employees should be permitted to use their employer’s computer for personal reasons during breaks and lunch hours as long as they do not violate the institution’s acceptable-use policy. Students should debate whether colleges have the right to monitor computer activity and whether computer users should be made aware of any monitoring software in use. Students might discuss how grades should not be impacted due to computer activity because grades are based on academics.
- Wireless Access
If you’re going to open a business, such as a sandwich shop or beauty salon, you need to decide if customers should be provided with Internet access. Consider the following:
- Should Internet access be free? If access is not to be free, how much should customers pay?
- How long should the average period of access be (and should there be a limit)?
Student responses may vary, but most will probably be in favor of free Internet access. Students may argue that many businesses already provide free, unlimited access and that this is becoming the norm. However, students should also acknowledge that such a policy may result in direct or hidden costs to the business. Direct costs may include the actual usage costs, while hidden costs may include lost sales since customers may linger longer but not spend more money and take seats away from new paying customers. The decision to provide free access may also depend upon the type of business – sandwich and coffee shops, automotive service centers, and similar business may be likely spots since customers may spend a fair amount of time there, but other business may not be able to accommodate customers staying for longer amounts of time. How students answer this question may also determine the decision to provide unlimited or time-limited access.

True–False
_____ 1. Routers are used to route data between two different networks. (T)
_____ 2. Two different types of network operating software cannot be deployed on the same network. (F)
Part 2 Critical Thinking
- Biometric Access to Networks
Biometric security devices are still expensive. But there are usually parts of any organization that need to be more secure than others, and you can often justify the cost of these devices for certain areas. Consider the following organizations and prepare a paper discussing which areas of the following businesses could most benefit from installing biometric security devices:
- Financial institution (bank)
- Public university that conducts scientific research
- Pharmaceutical company
Students should explore why each of these types of organizations would require enhanced security procedures. Would the same level of security be appropriate for every area of the organization? Which areas might need enhanced security procedures? If circumstances allow, students would benefit from class presentations and discussion of these topics. Critical thinking abilities will be enhanced by asking students to respond to all three examples, rather than just one of the choices. Students could be asked why some level of security procedures would be appropriate for just about any type of business organization.
- Monitoring Computer Usage in the Workplace
Software tools for monitoring computer usage are readily available on the Internet, often for free (such as Best Free Keylogger). In most jurisdictions, it’s legal for employers to install monitoring software on computer equipment they provide to employees. It’s usually illegal for employees to install monitoring software on computers owned by their employers for purposes of monitoring computer usage of coworkers or bosses. Do you think this double standard is fair? What circumstances do you think would justify an employee monitoring other employees’ computer usage? Should whistleblowers have the right to conduct computerusage monitoring? Fully explain your answers.
Students should agree that employers have the right to monitor employee use of employer resources. A discussion about proper professional conduct and business ethics could be beneficial for students. The question about getting approval before installing monitoring equipment could be broadened to include what reason would an employee give for making such a request? What protection is needed for whistleblowers? The viewpoints of students could be expanded by considering these questions from both an employee perspective and a management perspective. These issues are frequently in the news, and any recent topics could be included in classroom discussions.
