Explanation:
Security protocols are sets of rules and procedures designed to protect data transmission and communication over networks.

They define methods for secure key exchange, encryption, data integrity, and authentication. Examples include SSL/TLS, IPsec, and HTTPS.

These protocols are essential for protecting sensitive information and ensuring privacy in online interactions, such as financial transactions and data sharing.

Additional Information:
Some security protocols focus on network-level security (e.g., IPsec), while others safeguard application-layer communications (e.g., HTTPS).

Proper implementation of security protocols is crucial for maintaining trust in digital services and preventing data breaches.

Formal Definition:
Security protocols are sets of standardized rules and procedures that enable secure communication and data protection over networks, ensuring confidentiality, integrity, and authentication.
