The significance of network security protocols lies in their role in protecting data transmitted over networks. These protocols establish rules and procedures for secure communication, ensuring data integrity, confidentiality, and authentication. Common examples include HTTPS, SSL/TLS, and IPSec. By implementing these protocols, organizations can safeguard sensitive information from unauthorized access, reduce the risk of data breaches, and maintain user trust. Effective network security protocols are essential for protecting both personal and organizational data in increasingly digital environments.
