Secure Communication Protocols
Secure communication protocols are standardized methods and rules that ensure the confidentiality, integrity, and authenticity of data exchanged over networks, such as the internet. They use cryptographic techniques like encryption, digital signatures, and key exchange to protect against eavesdropping, tampering, and impersonation. Common examples include TLS/SSL for web traffic, SSH for remote access, and IPsec for network-layer security.
Developers should learn and use secure communication protocols whenever transmitting sensitive data, such as passwords, financial information, or personal details, to prevent data breaches and comply with regulations like GDPR or HIPAA. They are essential for building secure web applications, APIs, and network services, ensuring trust in e-commerce, banking, healthcare, and IoT systems.
