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 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The National Security Agency released a cybersecurity product Tuesday detailing how to detect and fix out-of-date encryption protocol implementations. Networks and systems that use deprecated forms of ...

For several years, the Internet Engineering Task Force (IETF) has been working to improve the Transport Layer Security (TLS) protocol, which is designed to help developers protect data as it moves ...

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 ...

In the natural world, species that share the same ecosystem often compete for resources, resulting in the extinction of weaker competitors. A new computer model that describes the evolution of the ...

TLS is the successor to the better-known SSL (Secure Socket Layer) encryption protocol; both are used to secure data communications between browsers and the destination server. The makers of the four ...
