Definition:
Data encryption is the process of converting plaintext into ciphertext using cryptographic algorithms to prevent unauthorized access. Only authorized users with the decryption key can convert the data back into its original form.
Use Cases:
- Used to protect sensitive information like financial transactions, emails, and personal data.
- Employed in securing communications between devices, such as in Virtual Private Networks (VPNs).

Questions and Answers:
- What are the different types of data encryption?
The two primary types are symmetric encryption (where the same key is used for encryption and decryption) and asymmetric encryption (which uses a public key for encryption and a private key for decryption).
- Why is encryption important in cybersecurity?
Encryption protects data from being accessed or modified by unauthorized parties, ensuring confidentiality and integrity.
- What are some common encryption standards?
Common encryption standards include AES (Advanced Encryption Standard), RSA, and 3DES (Triple Data Encryption Standard).
