Network Security in Cloud Environments
Network security forms a critical layer of defense in cloud computing environments, protecting data transmission paths between users, applications, and cloud resources. Cloud networks face unique security challenges due to their distributed nature and exposure to public internet infrastructure.
Data Transmission Protection
Data transmission protection in cloud environments relies on robust encryption protocols and secure communication channels. Virtual Private Networks (VPNs) establish encrypted tunnels for data transfer, while Transport Layer Security (TLS 1.3) provides end-to-end encryption with perfect forward secrecy. Advanced encryption methods include:
