Network Monitoring Interface Card All that you wanted to know about Network Monitoring Interface Card Here is a brief introduction of Network Monitoring Interface Card and its uses. Network Monitoring Interface Card (NMIC) is pretty much similar to a Network Card (NIC). Though, NMIC is used to passively or stealthily listen on a network, which is quite unlike a normal Network card. As a functional unit, Network Monitoring Interface Card does not have any MAC Address and thus it is possible that it will not have the ability to transmit. Also, it may be impaired to announce its existence in the network. Thus it differs from a normal Network Card. Network Card or Network Adaptor or LAN Adaptor or NIC is basically a computer part which allows different computers to converse through a network. It is an OSI layer 1, that is, Physical Layer and Layer 2, that is Data link Layer device as it can provide the access to the medium of networking physically and also provides a low level system for addressing using the MAC addresses. Thus it allows different users to connect using cables or even through wireless communication. MAC Address or Media Access Control Address or Ethernet Hardware Address or Hardware Address or Adapter Address is almost a unique identification to most of the Network Adaptors. It is like a name for a particular adapter. Thus, two network cards or adapters in two different systems will have different names, that is, different MAC addresses. However, due to MAC spoofing, it is possible to change the MAC address of the hardware today. Advanced or Enhanced Network Monitoring Interface Cards may have certain features which include the ability to offload the CPU Intensive Processing away from the System’s CPU, measurement of time with extremely high accuracy, filtering of traffic and the ability to do any other processing which is application specific. Network Monitoring Interface Card is generally used in detection and prevention of intrusion, lawful interception, network monitoring, Protocol analysis and flow analysis. One of the most noticeable manufacturers of the Network Monitoring Cards is Endace Ltd, which is a New Zealand based company. Thus the data, which is supplied by the Network Monitoring Interface Card, is having some of the details required for the Network Monitoring. This Card hardly interferes the normal dataflow and hence doesn’t effect the response time or the data flow rate or any other parameter. All it does is that it reports back its findings to the server or the system administrator.
