This is why Netscape developed a secure protocol known as a secure sockets layer (SSL). This evolved into what’s now known as transport layer security (TLS) with TLS version 1.2 and TLS 1.3 currently in use. SSL/TLS helps to facilitate the encryption of the data transmission channel between a client (an end user’s browser) and the server it’s talking to with the intent of hindering cybercriminals from stealing Continue Reading
