Data Protection and Encryption

Start with encryption

The page includes a mind map that introduces encryption as a way to make messages private using codes. It also describes decryption. The Safety and Security mind map covers encryption and decryption as coding and decoding text, while Cyber security explains how a key makes encrypted data readable.

Start with the introductory encryption map, then use the other maps to compare how they explain the process. After that, the encryption quiz gives you a way to check your understanding of the topic.

Explore threats and protection

The Data Protection mind map brings together viruses, hackers, phishing and backups. Another data protection map covers malware, including worms, Trojans and scareware. These maps give you a starting point for studying threats alongside ways to protect information.

A map on protecting information also covers antivirus software, firewalls, access levels and encryption. Work through the threats maps first, then look at the protection map to see which measures it lists. The threats-to-data quiz offers another way to check what you have studied.

Use flashcards alongside maps

Unit E: Data Security includes flashcards on risk management and protecting computer hardware. Another deck covers information categories such as sensitive, private, personal and business information. A business security deck lists measures including strong passwords, firewalls, antivirus protection and backups.

Use a map to organize the ideas, then go through a related flashcard deck to practice recalling them. Return to the map when you want to see the terms together again.

Study within the unit

Data Protection and Encryption is one section of Cybersecurity Fundamentals in Cybersecurity. The resources on this page connect encryption with threats, information classification and security measures through their shared focus on protecting information.

Choose a resource that matches the part you want to study and explore the page at your own pace.
