TLSyhteyksin

TLSyhteyksin is a Finnish term that translates to "TLS connections" in English. It refers to the secure communication channels established using the Transport Layer Security (TLS) protocol. TLS is a cryptographic protocol designed to provide secure communication over a computer network. It is widely used to encrypt the internet connection between a user's browser and a website, or between a server and its clients.

When a TLS connection is established, data exchanged between the two parties is encrypted, making it unreadable to anyone who might intercept it. This ensures the confidentiality and integrity of the transmitted information, protecting sensitive data such as login credentials, financial details, and personal messages. TLS also provides authentication, verifying the identity of the server or client to prevent man-in-the-middle attacks.

The implementation of TLS connections is crucial for online security and privacy. Websites that use TLS typically display a padlock icon in the browser's address bar, indicating a secure connection. This is often referred to as HTTPS (Hypertext Transfer Protocol Secure), where the 'S' signifies the use of TLS. The protocol has evolved through various versions, with TLS 1.2 and TLS 1.3 being the most current and secure standards. Maintaining up-to-date TLS configurations is essential for protecting against known vulnerabilities.
