In this case, the method of cybersecurity that the client employed before sending the file to Kit was **encryption** (Option B). Encryption is a process of converting information into a code to prevent unauthorized access. In this scenario, the client encoded the file using encryption to protect its contents from being viewed by unauthorized individuals.
Here's a breakdown to help you understand:
1. **Encryption**: It involves using an algorithm to convert data into a form that is unreadable without the correct key or password. This ensures that even if the file is intercepted, it remains secure and only the intended recipient with the key can decode and access the original information.
By employing encryption, the client ensured that the file's contents were secure during transmission and only Kit, with the key provided by the client, could decode and access the information. This method enhances data security and confidentiality in the digital realm.
I hope this explanation clarifies the concept of encryption in the context of cybersecurity measures. If you have any more questions or need further clarification, feel free to ask!
