Why is encryption important in network security?

Encryption is critical in network security because it safeguards data from unauthorized access during transmission. When data is encrypted, it is transformed into a format that is unreadable without the correct decryption key. This ensures that even if the data is intercepted while being transmitted over the network, it cannot be understood or manipulated by unauthorized parties. This protection is essential for maintaining the confidentiality and integrity of sensitive information, such as personal details, financial information, and business communications.

While other factors, such as improving connection speeds, increasing network availability, or simplifying user access management, can be important in network management and security, they do not directly address the fundamental need for protecting the privacy and security of data in transit. Encryption specifically targets the potential risks associated with data exposure and interception, making it a cornerstone of effective network security practices.
