Any device such as a laptop or phone that''s connected to a network, can be an easy entry point for attackers. The Endpoint Layer focuses on protecting these individual devices (endpoints).
This lecture provides a comprehensive introduction to all major networking devices, categorized by OSI layers (1 to 7). It clearly explains what each device is and how it functions within a network.
A router is a networking device that forwards data packets between different computer networks. It connects multiple packet-switched networks or subnetworks, managing traffic by
Layer 4, the Transport layer, connects the software with the hardware layers. SDN ("Software Defined Networking") is technology which allows more layers of the hardware to be implemented via software.
Network security works through multiple protective layers that control access at both the network edge and inside the environment. Each layer ensures only authorized users can access
