Attackers from both outside and within may have planted viruses or Trojan Horse programs, which can drain company resources or transmit classified data to unauthorized recipients. But, as real-world experience with a network will quickly demonstrate, there is no one single factor that explains all difficulties and failures, nor is there any one level of monitoring that can detect every issue. Consequently, network performance monitoring (NPM) must be done to find these errors quickly, so that they can be corrected as soon as possible. Customers who are turned away or disconnected due to any sort of network failure are likely to change vendors or providers. In today's world of networks, it is not enough simply to have a network assuring its optimal performance is key.
