Abstract: Attacks on the computer infrastructures are becoming an increasingly serious problem. There are available several information security techniques and tools to protect valuable information stored on computer systems against unauthorized access, use and destruction. This paper offers a perspective on the current state of Intrusion Detection Systems (IDS) describing the functionalities and components of such systems. A classification based on the type of protected system is made, along with the particular use of each of them. Further, it investigates the main techniques used to detect intruders, revealing the modality for discovering abnormal system events. Finally, the focus is on different types of intrusion detection tools available, few examples of them being presented.
