The Chief of Staff will be hosting a working lunch this week for your group of interns. In addition to the usual introductions and “getting to know you” discussions, you’ve been advised that there will be a discussion of the following article. https://securityintelligence.com/seasonal-employee-security-risks-present-danger-proactive-defense/ Each intern has been asked to write and bring a discussion paper containing their written responses to the following questions: 1. Do you agree or disagree with the author’s assertions regarding seasonal employees and cybersecurity risks in the work place? Why? 2. What steps can (should) managers take to reduce security risks associated with hiring seasonal or temporary employees? (Consider whether or not the Secure Computer User training course would be appropriate for these employees.) 3. How can managers show leadership in the area of cybersecurity defenses and best practices? As you write your response, remember to provide examples from the article and other readings for this week. Explain why you agree or disagree and provide examples, if appropriate. Your examples should be relevant to the hospitality industry and hotel operations. Consider the ways in which these types of companies are likely to use seasonal employees and the types of digital assets / information to which these temporary employees may have access. Include information from the Week 1 readings to support your responses / arguments. Remember to cite your sources using a consistent and professional style (APA recommended but not required). https://www.cisco.com/c/en/us/products/security/what-is-cybersecurity.html https://www.coranet.com/integrated-cybersecurity-strategy/

Although uniquely compliant with current law and guidance, is the collection and aggregation of data from the IoT and social media an ethical use of data. explain your opinion with supporting evidence. Make sure to address: How has the IoT and social media been affected by cybersecurity over time? Acceptable Use Policy. Although users agree to the conditions of it, is the data being collected used for entirely ethical purposes? User Agreement. If you use something that is provided for free, how does a company make a profit (e.g., how are free products and services monetized)? If companies build security directly into IoT devices before implementing the hardware into the system, the security would be sounder and could be tested ahead of time, instead of building security around the device as an afterthought. Suppose that you are one of the executive members in the company and face this option. However, the built-in security would cost three times higher than the regular without built-in security. Provide your rationale of the decision in light of the Christian worldview.
