You’ve learnt that collecting, storing and handling big amounts of data bring numerous challenges. Can you spot which challenge was faced on each of the scenarios below:
A TV network giving live coverage to Scotland’s independence referendum in 2014 had their computer generated graphics powered by data analytics. During a report on the referendum, graphics showed that 110% of Scotland’s population had been polled. According to the graphic, 58% of Scots had said “Yes” and 52% voted “No”. The graphic was obviously off on the total voter percentage, but it was also wrong about the fact that the majority of Scots actually voted “No”.

This case showed us that the importance of privileged account monitoring shouldn’t be underestimated. Insider misuse has always been a nightmare for security officers because it’s hard to detect and virtually impossible to prevent. To prevent users from taking advantage of their privileges, it is essential to enable continuous monitoring of their activities as well as ensure that employees’ permissions are properly granted; this will help you ensure that they are not extracting or manipulating data that is not required for their particular business needs.
