WebSocket Security
WebSocket security refers to the practices, protocols, and mechanisms used to protect WebSocket connections from vulnerabilities and attacks. It involves securing the WebSocket protocol, which enables full-duplex communication channels over a single TCP connection, commonly used in real-time web applications. Key aspects include authentication, authorization, encryption, and protection against threats like cross-site WebSocket hijacking and denial-of-service attacks.
Developers should learn WebSocket security when building real-time applications such as chat systems, live notifications, or online gaming, as insecure implementations can lead to data breaches or service disruptions. It is crucial for ensuring confidentiality, integrity, and availability in scenarios where persistent connections handle sensitive data, such as financial trading platforms or collaborative tools. Implementing security measures like TLS encryption and origin validation helps mitigate risks in high-traffic environments.
