Where there is a need for a great deal of analysis of network performance and security, switches may be connected between WAN routers as places for analytic modules. Some vendors provide firewall, [21] [22] network intrusion detection, [23] and performance analysis modules that can plug into switch ports. Some of these functions may be on ...
Using the switch to connect only the systems that are communicating provides much greater security than a network hub, which broadcasts all traffic over all ports, [3] allowing an eavesdropper to intercept and monitor all network traffic. A CAM Table Exhaustion Attack basically turns a switch into a hub. [4]
A router [a] is a computer and networking device that forwards data packets between computer networks, including internetworks such as the global Internet. [ 2 ] [ 3 ] [ 4 ] A router is connected to two or more data lines from different IP networks .
A repeater hub can therefore only receive and forward at a single speed. Dual-speed hubs internally consist of two hubs with a bridge between them. Since every packet is repeated on every other port, packet collisions affect the entire network, limiting its overall capacity. A network hub is an unsophisticated device in comparison with a switch.
In practice, a supplicant is a software application installed on an end-user's computer. The user invokes the supplicant and submits credentials to connect the computer to a secure network. If the authentication succeeds, the authenticator typically allows the computer to connect to the network. IEEE 802.1x network-diagram example.
Network architecture is the design of a computer network.It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as communication protocols used.
In computer networking, a media access control attack or MAC flooding is a technique employed to compromise the security of network switches.The attack works by forcing legitimate MAC table contents out of the switch and forcing a unicast flooding behavior potentially sending sensitive information to portions of the network where it is not normally intended to go.
A flat network is a computer network design approach that aims to reduce cost, maintenance and administration. Flat networks are designed to reduce the number of routers and switches on a computer network by connecting the devices to a single switch instead of separate switches.
