Future Business Leaders of America (FBLA) Cybersecurity Practice Test

What does decryption accomplish?

1. It compresses data for storage

2. It converts encrypted data back to its original form

3. It secures data against unauthorized access

4. It installs software updates

The correct answer is: It converts encrypted data back to its original form

Decryption accomplishes the process of converting encrypted data back to its original form, making it intelligible and usable again. Encryption transforms readable data into an unreadable format using algorithms and keys, protecting the information from unauthorized access. Decryption reverses this process by applying the correct key or algorithm to restore the original data, allowing authorized users to access and utilize the information as intended. This is important in cybersecurity, as it ensures that sensitive information can be securely stored and transmitted while remaining accessible to those who are authorized to view it. The other choices do not pertain to decryption; they relate to different concepts within data management and cybersecurity. For instance, compressing data for storage refers to reducing file size, securing data against unauthorized access pertains more to encryption processes, and installing software updates relates to maintaining software functionality and security.
