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 ...

Could anyone help find authoritative online sources and /or otherwise articulate on why it makes sense to go from the “top down” in the OST 7 -- layer model, instead of “bottom up”, when ...

The OSI model defines protocols for how a network technically handles communications at the various functional layers. Starting with electrons and photons at the physical layer (Layer 1), the model ...

The OSI model is the basis for most of the modern digital communications. Let’s dive into the seven layers of the OSI model and answers the billion-dollar question: how to protect the transmitted data ...

For many years, security monitoring relied on gathering data from layer 4 of the OSI model through such data types as NetFlow. Because layer 4 data dealt with the transport layer, it isn't the most ...

As cybersecurity threats grow more sophisticated, traditional network architectures struggle to keep pace, especially in sectors reliant on legacy hardware. IMPRES Technology Solutions has introduced ...

Other tips in this series have examined the seven-layer OSI model from the perspective of security. Although security was not the No. 1 goal of the designers of the OSI model, the idea behind these ...

Morey Haber, Chief Security Advisor at BeyondTrust, is an identity and technical evangelist with over 25 years of IT industry experience. Recently, I was reminiscing with a colleague about unique ...

The third layer of the OSI Model, the network layer, is where most network engineers focus their time and expertise. As Darragh commented in my post on the data link layer, Layer 2 is cool but Layer 3 ...
