What is the primary purpose of data visualisation?

• To store data

• To transform raw data into visual formats for easier understanding

• To secure sensitive information

• To collect data

Why is data security crucial when working with data visualisations?

• To improve the aesthetics of the visualisation

• To protect sensitive or confidential information

• To increase data storage capacity

• To enhance data processing speed

What does cybersecurity refer to?

• Practices to increase internet speed

• Technologies to protect data from unauthorised access and attacks

• Methods for visualising data

• Strategies for data collection

How can data be protected during visualisation?

• By reducing the amount of data used

• By encrypting the data

• By sharing it publicly

• By using outdated software

What are access controls?

• Tools to improve data visualisation

• Methods that restrict data access based on user roles

• Techniques for data encryption

• Systems for data collection

Why is it important to use secure platforms for sharing data visualisations?

• To make the visualisations look more professional

• To ensure built-in security features protect the data

• To limit the number of users accessing the data

• To simplify the visualisation process

What is the significance of encryption in data security?

• It makes data easier to read

• It protects data from being intercepted by converting it into a code

• It increases the size of the dataset

• It eliminates the need for backups

Why is data backup important?

• To save on storage costs

• To ensure data can be recovered if lost or compromised

• To improve data visualisation quality

• To speed up data processing

Which of the following is a common method for backing up data?

• Using flash drives only

• Cloud storage

• Printing data on paper

• Relying solely on manual backups

What is an advantage of using automated backup systems?

• They require constant manual intervention

• They ensure data is regularly backed up without manual processes

• They are less secure than manual backups

• They limit data accessibility
