Answer : A
Francis can make a Subject Access Request. This is when you ask what data do you hold about me. The company must respond within 40 calendar days. A Freedom of Information request is different- this is when a member of the public asks the government to reveal information such as 'how much money have you spent on replacing toilet seats in Parliament?'.

Henry is the Head of IT at Purple Rain Ltd and is presenting a case to the Senior Leadership Team to ask for more investment in the company's IT strategy. Henry believes the company has an issue with data resilience and is asking for more money to be invested in this. He has completed a Business Impact Assessment (BIA) to better understand what data the company holds. Jon is the Head of Procurement and has listened intently to Henry's presentation. He has decided to go back to his department and complete a thorough risk assessment, as he is aware his team holds a lot of data on suppliers and contracts. The CEO of Purple Rain, Roger Nelson, has asked Henry about next steps in order to protect the company from further risks associated with the IT strategy. Data is currently stored on servers located at Purple Rain's Headquarters. The server room is locked at all times of the day and is only accessible to staff members who have a key. The building itself is extremely secure with CCTV systems located both inside the server room and outside it. However, the server room is prone to overheating.

A person who enters into another person's computer via illegal means for personal gain, for example to steal data which will benefit them personally, is known as what?
Answer : A

Black swan is about finding patterns in data that don't exist and came up in an earlier chapter. Black-hat hacking is from p.147. I don't think hackers are obliged to wear hats, it's probably just a metaphor, but I've never met one to ask.
