Secure protocols are essential for protecting data as it travels across networks. They ensure that information remains confidential and integral, preventing unauthorized access and tampering. Common examples include HTTPS, SSL/TLS, and SSH, which are widely used to secure web traffic and remote connections. These protocols utilize various encryption techniques to safeguard data. By establishing a secure channel between communicating parties, they help maintain privacy and trust in digital communications. As cyber threats continue to evolve, the importance of implementing secure protocols cannot be overstated, making them a fundamental aspect of modern cybersecurity practices.
