8 Safety and security (1 questions)
Answer:
SSL (Secure Socket Layer) and encryption work together to secure data transmitted over the internet. SSL creates a secure, encrypted connection between a web server and a web browser.
How SSL works: When a user visits a website using HTTPS, the browser and server negotiate an SSL connection. This involves exchanging digital certificates. The server presents its SSL certificate to the browser, which verifies its authenticity using a Certificate Authority. Once the connection is established, all data transmitted between the browser and server is encrypted using a cryptographic algorithm. This encryption prevents eavesdropping and tampering by third parties.
Importance of SSL certificates: SSL certificates are crucial for establishing trust and verifying the identity of a website. They ensure that the data transmitted is secure and hasn't been altered in transit. Without an SSL certificate, a browser will display a warning message, indicating that the connection is not secure. A table summarizing the key aspects is below:
| SSL/TLS Role | Description |
| Encryption | Transforms data into an unreadable format to protect confidentiality. |
| Authentication | Verifies the identity of the website, preventing man-in-the-middle attacks. |
| Data Integrity | Ensures that data is not altered during transmission. |
