## Senses

### 1. secure web protocol

noun · CEFR B2 · Technical

Stands for Hypertext Transfer Protocol Secure. It is the standard way to send data safely between your web browser and a website.

For teachers: Abbreviation for Hypertext Transfer Protocol Secure. An extension of HTTP that uses TLS/SSL encryption to secure data transfer and verify the identity of the website.

- You should only enter your credit card details on websites that use HTTPS.
- Modern browsers now flag any site not using HTTPS as insecure, as the protocol is essential for protecting sensitive user data from interception.

Usage: Usually written in capital letters and appears at the beginning of a web address.

Teaching tip: Explain to students that the 'S' stands for 'Secure' and is the key difference from the older HTTP protocol.

## Examples

- Always check for HTTPS in the address bar before entering your password.
- The website was flagged as insecure because it used standard HTTP instead of the encrypted HTTPS protocol.
- Modern web browsers now prioritize HTTPS connections by default, warning users of potential security risks when a site fails to provide a valid SSL certificate for encrypted data transmission.
