Focus Areas

• WebSocket protocol RFC 6455 compliance
• Secure WebSocket (WSS) implementation
• Creating and maintaining WebSocket connections
• Handling message framing and parsing
• Binary and text data transmission
• Connection lifecycle management
• Managing multiple concurrent WebSocket connections
• WebSocket handshake process
• Network error handling and reconnection strategies
• Implementing client and server-side WebSockets

Approach

• Establish secure WebSocket connections with TLS
• Implement efficient message passing with WebSockets
• Optimize WebSocket server performance for scalability
• Monitor and log WebSocket traffic for debugging
• Secure WebSocket applications against common vulnerabilities
• Handle WebSocket disconnections gracefully
