SCENARIO
It should be the most secure location housing data in all of Europe, if not the world. The Global Finance Data Collective (GFDC) stores financial information and other types of client data from large banks, insurance companies, multinational corporations and governmental agencies. After a long climb on a mountain road that leads only to the facility, you arrive at the security booth. Your credentials are checked and checked again by the guard to visually verify that you are the person pictured on your passport and national identification card. You are led down a long corridor with server rooms on each side, secured by combination locks built into the doors. You climb a flight of stairs and are led into an office that is lighted brilliantly by skylights where the GFDC Director of Security, Dr. Monique Batch, greets you. On the far wall you notice a bank of video screens showing different rooms in the facility. At the far end, several screens show different sections of the road up the mountain Dr. Batch explains once again your mission. As a data security auditor and consultant, it is a dream assignment: The GFDC does not want simply adequate controls, but the best and most effective security that current technologies allow.
"We were hacked twice last year," Dr. Batch says, "and although only a small number of records were stolen, the bad press impacted our business. Our clients count on us to provide security that is nothing short of impenetrable and to do so quietly. We hope to never make the news again." She notes that it is also essential that the facility is in compliance with all relevant security regulations and standards.
You have been asked to verify compliance as well as to evaluate all current security controls and security measures, including data encryption methods, authentication controls and the safest methods for transferring data into and out of the facility. As you prepare to begin your analysis, you find yourself considering an intriguing question: Can these people be sure that I am who I say I am?
You are shown to the office made available to you and are provided with system login information, including the name of the wireless network and a wireless key. Still pondering, you attempt to pull up the facility's wireless network, but no networks appear in the wireless list. When you search for the wireless network by name, however it is readily found.
What type of wireless network does GFDC seem to employ?

Which of the following is considered a records management best practice?

SCENARIO
Clean-Q is a company that offers house-hold and office cleaning services. The company receives requests from consumers via their website and telephone, to book cleaning services. Based on the type and size of service, Clean-Q then contracts individuals that are registered on its resource database - currently managed in-house by Clean-Q IT Support. Because of Clean-Q's business model, resources are contracted as needed instead of permanently employed.
The table below indicates some of the personal information Clean-Q requires as part of its business operations:

Clean-Q has an internal employee base of about 30 people. A recent privacy compliance exercise has been conducted to align employee data management and human resource functions with applicable data protection regulation. Therefore, the Clean-Q permanent employee base is not included as part of this scenario.
With an increase in construction work and housing developments, Clean-Q has had an influx of requests for cleaning services. The demand has overwhelmed Clean-Q's traditional supply and demand system that has caused some overlapping bookings.
Ina business strategy session held by senior management recently, Clear-Q invited vendors to present potential solutions to their current operational issues. These vendors included Application developers and Cloud-Q's solution providers, presenting their proposed solutions and platforms.
The Managing Director opted to initiate the process to integrate Clean-Q's operations with a cloud solution (LeadOps) that will provide the following solution one single online platform: A web interface that Clean-Q accesses for the purposes of resource and customer management. This would entail uploading resource and customer information.
A customer facing web interface that enables customers to register, manage and submit cleaning service requests online.
A resource facing web interface that enables resources to apply and manage their assigned jobs.
An online payment facility for customers to pay for services.
What is a key consideration for assessing external service providers like LeadOps, which will conduct personal information processing operations on Clean-Q's behalf?
