Detection of Attacks in an Intrusion Detection System
نویسنده
چکیده
Intrusion detection is the act of detecting unwanted traffic on a network or a device. A intrusion detection system (IDS) provides a layer of defense which monitors network traffic for predefined suspicious activity or patterns, and alert system administrators when potential hostile traffic is detected. Intrusion detection faces a number of challenges; an intrusion detection system must reliably detect malicious activities in a network and must perform efficiently to cope with the large amount of network traffic.Network based intrusion detection are the most deployed IDS. An IDS can be a piece of installed software or a physical appliance. Many IDS tools will also store a detected event in a log to be reviewed at a later date or will combine events with other data to make decisions regarding policies or damage control. This paper discusses the various types of attacks that can be detected in a simulated network environment. The different types of attacks are Probe attacks,R2L,Dos and U2R attacks.

A New Intrusion Detection System to deal with Black Hole Attacks in Mobile Ad Hoc Networks
By extending wireless networks and because of their different nature, some attacks appear in these networks which did not exist in wired networks. Security is a serious challenge for actual implementation in wireless networks. Due to lack of the fixed infrastructure and also because of security holes in routing protocols in mobile ad hoc networks, these networks are not protected against attack...
متن کاملEvaluation of an Intrusion Detection System for Routing Attacks in Wireless Self-organised Networks
Wireless Sensor Networks (WSNs) arebecoming increasingly popular, and very useful in militaryapplications and environmental monitoring. However,security is a major challenge for WSNs because they areusually setup in unprotected environments. Our goal in thisstudy is to simulate an Intrusion Detection System (IDS)that monitors the WSN and report intrusions accurately andeffectively. We have thus...

Internet of Things is an ever-growing network of heterogeneous and constraint nodes which are connected to each other and the Internet. Security plays an important role in such networks. Experience has proved that encryption and authentication are not enough for the security of networks and an Intrusion Detection System is required to detect and to prevent attacks from malicious nodes. In this ...
