TLS/SSL icon: a cybersecurity vector illustrating the TLS handshake behind every HTTPS connection. The device and the server each have a dashed timeline, read top to bottom. First the client sends a hello with the methods it supports. The server replies with its certificate to prove its identity. The client checks it, and both sides agree a shared session key that no one else holds. That key locks the connection - shown by the padlock - and only then does real data flow, as packets inside one sealed channel running directly from device to server. The security is not just the pipe: it is earned by the handshake first. Part of a cybersecurity icon set on attack, defence and security.
