**What is the main purpose of data encryption in cybersecurity?**
The main purpose of data encryption in cybersecurity is to protect sensitive information from unauthorized access and breaches. By converting plaintext data into coded ciphertext, encryption ensures that even if data is intercepted, it remains unreadable without the appropriate decryption key. This process safeguards personal details, financial transactions, and confidential communications, thereby maintaining the integrity and confidentiality of information. Encryption is a critical component of modern security practices, helping organizations comply with regulations and defend against cyber threats.
