What are Network Security Protocols?
Security protocols are a type of network protocol ensuring that nothing outside of the networks parameter. They are a sequence of operations that ensure protection of data. When it is used with a communications protocol, it ensures safe and secure delivery of data between the two parties. Network security protocols define the methodology and processes to secure network data from any illegitimate attempt to review or extract the contents of data.
Network security protocols are actually designed to prevent unauthorized users, applications, services or devices from accessing the data on network. This applies virtually to all the data types regardless of the medium of network used.
A protocol describes how to use the algorithms. A complete detailed protocol includes details about the data structures and their representations, at a point where it can be used to implement different, interoperable versions of a program.
They generally implement cryptographic and encryptive technique to secure the data and it can only be decrypted using a special, mathematical formula, logical key, algorithm, and/or a combination of all of them.
Some of the most commonly used network security protocols are:
- SFTP(Secure File Transfer Protocol)
- HTTPS (Secure Hypertext Transfer Protocol)
- SSL (Secure Socket Layer)
