E-training for personal data management and privacy

Secure connection during data transmission means that the data is protected during transmission and cannot be intercepted or manipulated by third parties. A secure connection is usually achieved by encrypting the data.

There are several methods to establish a secure connection, including SSL/TLS (Secure Sockets Layer/Transport Layer Security) for encrypting web connections, VPN (Virtual Private Network) for secure connection between remote networks or devices, and SSH (Secure Shell) for secure remote control of computers.

A secure connection is especially important when transferring sensitive information such as usernames, passwords, credit card information, or other personal data. Without a secure connection, such information can be intercepted and stolen by attackers.

Therefore, make sure you have a secure connection and check the certificate.

You can recognize a secure connection by https in the web address.

Example of a secure connection:

You can access and verify the certificate via the lock icon.

A website's certificate is a digital document issued by a trusted certification authority that verifies the identity of the website. It contains information such as the name of the website, the name of the issuing certification authority, the purpose of the certificate, and the validity period of the certificate. The certificate also contains a public key that is used to encrypt data.

The certificate is provided by the website and can usually be verified by clicking the lock icon in the browser's address bar. If the certificate is valid, a secure connection is established and all data exchanged between the user's browser and the website is encrypted.
A certificate ensures that the website displayed is indeed the one mentioned in the address bar, and that data is transmitted in encrypted form. When a user accesses a website that does not have a valid certificate, a warning message is usually displayed, indicating that the connection may not be secure. In this case, users should be careful and not visit the website unless they are sure that the website is legitimate and that the data they are transferring is not confidential.
