TLSHTTPSsuojaus

TLSHTTPSsuojaus refers to the security provided by Transport Layer Security (TLS) used in conjunction with HTTP, commonly known as HTTPS. This combination ensures that communication between a web browser and a web server is encrypted and authenticated. TLS is a cryptographic protocol designed to provide communications security over a computer network. When implemented with HTTP, it creates HTTPS, which is the secure version of HTTP.

The primary function of TLSHTTPSsuojaus is to protect the confidentiality and integrity of data exchanged online. Confidentiality is achieved through encryption, meaning that any information sent between the client and server is scrambled and unreadable to anyone who might intercept it. Integrity ensures that the data has not been tampered with during transmission.

Furthermore, TLSHTTPSsuojaus provides authentication. This means that the user's browser can verify the identity of the website it is connecting to, preventing man-in-the-middle attacks where an attacker impersonates a legitimate website. This verification is typically done through digital certificates. When a browser connects to an HTTPS website, it requests the site's SSL/TLS certificate. The browser then checks if the certificate is valid, issued by a trusted Certificate Authority, and matches the domain name being accessed.

The use of TLSHTTPSsuojaus is crucial for protecting sensitive information such as login credentials, credit card numbers, and personal data. Modern web browsers visually indicate the presence of HTTPS protection, often with a padlock icon in the address bar, giving users confidence that their online interactions are secure.
