Which security measure specifically aims to protect against unauthorized data breaches?

Encryption is a vital security measure designed specifically to protect against unauthorized data breaches. It works by converting data into a coded format that can only be read or accessed by individuals who possess the correct decryption key or password. This means that even if an unauthorized party gains access to the data, they would only encounter meaningless code without the ability to translate it back to its original, readable form.

This added layer of security ensures that sensitive information—such as personal data, financial records, or confidential business communication—remains protected, significantly reducing the chances of data breaches.

While antivirus software helps protect against malware and can play a role in securing systems against certain types of breaches, it does not specifically encrypt data. Network speed optimization and web hosting are not security measures at all; they focus more on improving website performance and reliability rather than protecting data from unauthorized access.
