5. Cloud storage / computing • Cloud computing, often referred to as simply “the cloud,” is the delivery of on-demand computing resources. (e.g., computer networks, servers, storage, applications and services) • Cloud storage is a cloud computing model in which data is stored on remote servers accessed from the Internet, or "cloud."

They use a virtual private network (VPN) to access the LAN. • Discuss the implications to the trainer of accessing training materials and delegate information using a VPN. (6 marks)

13. Mark Scheme • Benefits of using VPN • The VPN will give trainers secure access to resources on the LAN when they are not in the head office. • Will need to have laptops set up so that a VPN client can be launched. This will enable the server and laptop to verify each other as authentic and subsequently all internet communication will be encrypted and secured from eavesdropping. • Trainers will use a log in and password to access the VPN. • The VPN gives secure access even when delegates are using unsecured public networks. • The delegates’ information must be kept secure to comply with the DPA, using the VPN will help ensure security. • Hotels frequently have unsecured networks. Trainers will be in hotels, etc. overnight if they are delivering meetings on consecutive days, or if they have to travel long distances from home. • Trainers may be home based and may have to travel to venues, trains, coffee shops, etc. service areas/stations may provide unsecured WiFi. • Types of material that will be accessed • The delegates attending courses may change at short notice, trainers will need to have access to up-to-date lists and detail information. Similarly, they will need to provide head office with information about attendance. • Trainers will need access to the latest versions of training materials, therefore they must have access to the LAN at all times when they are not in the head office. • The trainers may need to provide feedback on courses to allow materials to be updated. • The trainers may need to provide attendance information for billing purposes/follow up with delegates. • May need to communicate with head office, e.g. via email if any issues/ queries arise.
