摘要：Computer systems of today are subject to many attacks and it can be anticipated that these problems will increase in the future era. One way of protecting the systems is to use better authentication and other categories of preventive security mechanisms. These mechanisms do not offer good enough protection in most cases and they should therefore be complemented with monitoring and detection mechanisms. Intrusion detection over the network is indeed an important field of the information security. Although many intrusion detection systems are widely available today, the technology is still young and the combat against threats from both internal and external sources seems to be an endless. Intrusion detection systems have turn out to be a significant factor in security toolbox. Nevertheless, numerous security specialists are still in the gloomy about intrusion detection phenomena and hesitant about what intrusion detection systems tools do; how to utilize them, or why they are a compulsory. In this article we will present a succinct overview of intrusion detection systems, including a sketch; the functionalities and the diverse techniques of intrusion detection that could provide work for.
