How does encryption help protect data in transit over a network?

Encryption is a critical component of network security that helps safeguard data during transmission over a network. By converting plaintext data into ciphertext using complex algorithms, encryption ensures that even if intercepted by unauthorized parties, the information remains unreadable and secure.

When data is encrypted before being transmitted, it becomes virtually impossible for unauthorized individuals to decipher or tamper with the information. This helps prevent data breaches, identity theft, and other cyber threats that pose a risk to sensitive data.

Overall, encryption serves as an essential security measure for protecting the confidentiality and integrity of data as it travels through network infrastructure, making it a fundamental aspect of ensuring secure communication and data exchange.
