A collection of encryption, authentication, and authorization protocols for ensuring communication and data security.
Overview
Security Protocols
Security protocols are a set of technical standards and procedures designed to protect the confidentiality, integrity, and availability of network communications and data. They are utilized at various layers including TLS/SSL for communication encryption, IPsec for VPN protection, OAuth/OpenID Connect for authentication and authorization, and SSH for secure remote access. In modern digital infrastructure, these protocols form the foundation for defense against cyber attacks and privacy protection.
