After learning about safe transmission of data and cryptography, the textbook introduces security protocols — the rules and procedures that protect data and communication on networks. Security protocols keep sensitive information, like passwords, private and safe from unauthorized access. These protocols also verify user identities and ensure data remains unchanged during transmission.
The textbook explains that examples include HTTPS for secure browsing and SSL/TLS for secure data exchange.
Definition
Security Protocols are rules and procedures to protect data and communication on networks. They keep sensitive information private and safe from unauthorized access, verify user identities, and ensure data remains unchanged during transmission.
In simple words: Security protocols are the rules that keep data safe when it travels across networks.
Main Idea
The core idea is that security protocols provide a structured way to protect data in transit. They are not just about encryption — they also include authentication, integrity checks, and secure communication channels.
Keep sensitive information private and safe from unauthorized access.
Verify user identities.
Ensure data remains unchanged during transmission.
Include examples like HTTPS for secure browsing and SSL/TLS for secure data exchange.
