• A QNap TS-412 NAS is used to backup workstation data (at each employee's discretion) using WinSCP. The username/password for the NAS admin account is zoom/zoom.

• A Windows 2000 Server was previously operational in the organisation but a power surge resulted in hardware no longer functioning.

• Each employees receives on average 40-100 spam messages each day.

You have been hired to advise on the cyber security issues and develop a range of recommendations to ensure ZP can fulfil current and future contractual obligations.

The employees are comfortable, and reluctant to change their current cyber security behaviour. Many of the employees believe that the company is functioning correctly and does not need a new cyber security operational model. ZP's manager is committed to addressing the cyber security issues and culture of the workplace and has allocated a sum of $250,000 to achieve the goal.

• An explanation/demonstration of the potential consequences of the identified issue.

• A detailed explanation/demonstration of how you propose to address the issue.

• Why is your chosen solution better than alternative approaches?

• A detailed breakdown of the cost in addressing the selected issue.
