Network Security Health Checking

摘要

In current times, sending confidential data over the Internet is becoming more commonplace every day. Some people and organisations, e.g. commercial banks, are completely dependent on electronic transmission of confidential data. Computer networks are the transport medium for these electronic data transmissions. Hackers mostly target networks as their primary point of infiltration, whether it is internal or external from a private network. What tools do we use to check the "health status" of a network? What is the role that network-security services play in current network secuity? This paper will address these questions and gives a perspective of the current status regarding network-security technologies.
