In order to keep data secure, which three things should be considered?
This is the CIA triangle which is from p.143. The three aspects are the three corners of the triangle. Remember this one for the exam as I've heard it comes up frequently. Just remember data security = CIA = confidentiality, integrity and availability.

Green Pants Ltd has a lot of sensitive data around their unique designs for pants. Daniela, one of the designers, has noticed there is a weakness in their IT system, which means that data may be accessible to people outside the company. She would like the company to invest in software that can hide or disguise the data so that if it is ever stolen, the designs of the pants are not readable to others. What software is Daniela requesting?
Encryption makes data unreadable by converting it into an encoded format using an algorithm. If the data is stolen, it remains unreadable without the decryption key. A common example is WhatsApp's end-to-end encryption. (P.188)
What is the benefit of an organisation using blockchain in data management?
Blockchain ensures data integrity by preventing modifications. If changes are needed, new blocks are added instead of altering existing ones. This enhances transparency and security, as blockchain is decentralized and not vulnerable to a single point of failure. (P.189)
Identifying patterns in data using data from more than one source is commonly known as...?
Collaborative filtering is a technique used in recommendation systems where multiple data sources (e.g., previous purchases, browsing habits, and ratings from other users) are combined to predict user preferences.
If data has been modified, which aspect of the Information Security triangle has been breached?
Integrity refers to the trustworthiness and accuracy of data. If data has been altered, its integrity has been compromised. The Information Security Triangle consists of Confidentiality, Integrity, and Availability (CIA). Accuracy is not part of this model. (P.143)
