What is encryption and why is it crucial for network security?

Encryption is a crucial aspect of network security that ensures the confidentiality, integrity, and authenticity of data transmitted over a network. It is a process of converting plaintext into ciphertext using complex algorithms and keys, making it unreadable to unauthorized individuals. Encryption prevents data breaches by providing a secure channel for communication, protecting sensitive information from interception or unauthorized access. It safeguards against various forms of cyber threats, including eavesdropping, data theft, and identity theft. In the event of a network breach, encrypted data remains unintelligible to attackers, providing an additional layer of protection. Encryption is necessary to maintain trust, compliance, and privacy in both personal and business communications, ensuring that sensitive information remains safe from prying eyes and malicious activities in an increasingly interconnected world.
