Network attacks and countermeasures

As the Internet becomes more mature and a part of our daily life, technologies used to provide continuous services of the Internet under all circumstances become more crucial. Collectively, these technologies ensure that resources are always available and stable. Since network attack is very easy to deploy and has very low cost, it has become the main reason of network instability and is the most challenge of current network security professionals. In this paper, we have studied the factors that cause network instability and investigated the potential countermeasures that enhance network security. We have proposed a framework to indicate the requirements of future queue management algorithm design.
