security protocols

Security protocols establish the hard rules for digital exchange. TLS 1.3 (Transport Layer Security) remains the gold standard for web traffic, eliminating obsolete algorithms like SHA-1 to slash handshake latency. For network-level protection, IPsec provides robust tunneling for VPNs by leveraging AES-256 encryption. These protocols use defined handshakes to verify certificates and negotiate keys, ensuring that even if a packet is intercepted, the payload remains unreadable. Implementation focuses on minimizing the attack surface while maintaining high throughput for enterprise systems.
