You have recently been appointed as the new IT risk manager of a countrywide online trading business called DirectToCust which sells items directly to the public. Its headquarters are located in Cape Town, in the Western Cape and has warehouses in Gauteng, KZN, and the Free state. The company employs over 200 call centre agents and about 10 business managers for both inbound and outbound transactions and logistics. They work both day and night shifts in an open-plan workspace of around 40 x 38 m with each agent having their own desk, networked computers and essential office stationery to conduct business. Most, if not all, call centre agents' desktop PCs are connected to a local network using Ethernet cabling while most line managers' laptops are wirelessly connected to enable free movement around the premises. All the servers, switches, router, gateways, firewalls, etc., are located at the adjacent IT office and maintained by one network administrator and six support technicians (four dayshift and two nightshift), the company opted for software-as-a-service, through various cloud computing service provider for all their software needs and therefore the presence of IT personnel is for day-to-day business support only. Before your recruitment, the company was experiencing a couple of complaints such as:
