What is “encryption” in cybersecurity?
a) The process of converting data into a code to prevent unauthorized access
b) A technique to increase internet speed
c) A method of compressing files
d) A way to delete files securely
Answer:
a) The process of converting data into a code to prevent unauthorized access
Explanation:
Encryption is a cybersecurity technique that transforms readable data (plaintext) into an encoded format (ciphertext), making it inaccessible to unauthorized users. Only someone with the proper decryption key can revert the data back to its original format.
Encryption is widely used to protect sensitive information, such as personal details, financial data, and confidential communications, especially when transmitting data over the internet or storing it on devices.
Encryption provides a strong layer of security, ensuring that even if data is intercepted, it remains unreadable to anyone without the correct key. This is essential for protecting privacy and maintaining the confidentiality of information.
