SSL / TLS
Pronunciationes-es-el / tee-el-es
Definition
Security protocols that encrypt data transmitted between a client and a server, protecting it from interception and tampering.
Where you hear it
During server setup, security audits, domain certificate configuration, or when troubleshooting ERR_SSL_PROTOCOL_ERROR.
Examples
The server is configured to redirect all incoming HTTP traffic to HTTPS using SSL / TLS.
We need to renew the SSL / TLS certificate before it expires next month.
Common mistake
Thinking SSL is still actively used, when in fact it has been completely replaced by its secure successor, TLS.
