Part 1 of this article looks at low-level communications protocols, including PPP and Ethernet, and their specific security features and requirements.] Now that we have discussed the lower-level ...

The Internet encryption protocol TLS – short for Transport Layer Security – is being fundamentally modified. Involved in attacks, researchers have contributed to revealing security gaps in the ...

The National Security Agency (NSA) has shared guidance on how to detect and replace outdated Transport Layer Security (TLS) protocol versions with up to date and secure variants. The US intelligence ...

The two most common transport layer protocols are the transmission control protocol (TCP) and the user datagram protocol (UDP). One of the main differences between the two protocols is reliability.

The Transport Level Security (TLS) protocol is one of the few rock-steady spots in the rapidly changing computing industry, but that’s about to change as quantum computers threaten traditional ...

The popularity of wireless LANs is increasing as is the use of wireless internet access points, so the need for secure and encrypted e-mail exchanges is becoming more critical. While there are many ...

In the past we considered transport protocols such as RTP (Real-time Protocol), ABR (Adaptive Bit Rate), SDVoE (Software Defined Video over Ethernet), SRT (Secure Reliable Transport), QUIC (Quick ...

I like to think of the transport layer as the layer of the OSI Model that enables more interesting traffic. While we network engineers may love a lot of the simpler uses of the IP protocol and ...
