Security: Adoption of TLS 1.3 for Secure Web Communication Grows

By Dick Weisinger

The TLS (Transport Layer Security) 1.3 protocol was officially released in the summer of 2018. It provides secure communication between web browsers and backend servers and is a replacement for SSL. TLS 1.3 supercedes TLS 1.2 and includes newer, more secure cryptography, operates with lower latency, and offers better privacy protection. The new protocol is expected to secure web services against DDoS attacks and data breaches.

Most of the major browsers already support it. Large CDNs like Akamai and Cloudflare now use TLS 1.3 as the default protocol.

Rohan Pinto, CTO/Founder of 1Kosmos BlockID, wrote for Forbes that “TLS 1.3 offers superior privacy for data exchanges by encrypting most of the transactions to safeguard the identities of the users and obstruct traffic exploration. Also, TLS 1.3 secures communication between client/server applications by encrypting the entire handshake during the client/server interactions, subsequent to the first client “hello.” Consequently, existing communications are safeguarded even in the case where future communications are tampered with.”

David Holmes, senior analyst at Forrester Research, said that “as TLS 1.3 and DNS-over-HTTPS gain momentum, teams need to plan now to augment their inspection programs.Explicitly lay out a visibility upgrade program or piggyback it onto a larger effort like network modernization or digital transformation. Within the larger effort, incorporate tactical approaches to recapture network metadata and lost decryption capabilities.”
