The principle behindlayered network security strategiesis simple: If one tool is unable to stop a threat, others are in place that could effectively block it.Network security layers work in concert to provide more effective security than any one tool alone. Alayered network security strategyhas th...
Notice that the third layer from the bottom is called Network, but network security does not apply only to this layer. Every device in a computer network functions on multiple layers when processing information. Given that, each layer must be secure for the network to be considered secure. In...

Get an overview of the networking technologies and products that protect your network and data. These include firewalls and security for mobile devices and wireless LANs.
Network Security – Data Link Layer - We have seen that rapid growth of Internet has raised a major concern for network security. Several methods have been developed to provide security in the application, transport, or network layer of a network.
Network security solutions protect computer systems from internal and external security threats and cyberattacks.
Larger organizations who need more comprehensive protection of a distributed environment and don’t have the resources in house, can choose anXDR servicefor cross-layered detection and response. XDR collects, normalizes, and then correlates data over a variety of security layers, including endpoints,...
