An Intrusion Detection System (IDS) is a system that tries to perform intrusion detection by comparing observable behaviour against suspicious patterns. The objective of intrusion detection is to monitor network resources and to detect abnormal and irregular behaviours and abuses. This concept has been around for the past several years but only recently it has seen a dramatic rise in interest of researchers and system developers for incorporation into the overall information security infrastructure. This survey gives the overall study about the IDS, its nature and techniques, tools used in the area of intrusion detection. Finally the survey gives the real-time working performance of top selected Intrusion Detection and Intrusion Prevention tools. This paper helps in analysing and evaluating of various IDS tools used in high-speed networks.
