Network devices are any items of hardware connected to the network architecture. Every network should be documented and mapped. Mapping enables managers to understand which devices require protection. Company networks generally rely on several device types: ...
IP addresses route a packet across the whole global Internet, while MAC addresses help the packet make the small, local hop between hardware devices. Sophisticated networking is possible because each of your networked devices has both a MAC and an IP address.With that comes the next question, ...
air.trace( "hardware address: " + interfaceObj.hardwareAddress ); if( interfaceObj.subInterfaces != null ) { air.trace( "# subinterfaces: " + interfaceObj.subInterfaces.length ); } air.trace("# addresses: " + interfaceObj.addresses.length ); ...
This completes the set up and the data of the service protocol can now be communicated.In this example, the firewall passes the traffic to the web server (HTTP -> 80) and the web server responds with the acknowledgement.In all these examples a firewall could be a separate hardware device...
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.Layer 7 - Application LayerThe business logic and functionality of the application lies here. This...
