Intrusion detection system - Wikipedia

An intrusion detection system IDS is a device or software application that monitors a network or systems for malicious activity or policy violations. Any intrusion activity or violation is typically reported either to an administrator or collected centrally using a security information and event management SIEM system. A SIEM system combines outputs from multiple sources and uses alarm filtering techniques to distinguish malicious activity from false alarms. IDS types range in scope from single computers to large networks. A system that monitors important operating system files is an example of an HIDS, while a system that analyzes incoming network traffic is an example of an NIDS. It is also possible to classify IDS by detection approach. The most well-known variants are signature-based detection recognizing bad patterns, such as malware and anomaly-based detection detecting deviations from a model of "good" traffic, which often relies on machine learning.

IDPS typically record information related to observed events, causing false positives e. Malware topics. Legitimate users may deviate from Network based IDS the base-line. Whitman; Herbert J.

An intrusion prevention system IPS is a form of network security that works to detect and prevent identified threats. Intrusion prevention systems continuously monitor your network, looking for possible malicious incidents and capturing information about them. The IPS reports these events to system administrators and takes preventative action, such as closing access points and configuring firewalls to prevent future attacks. IPS solutions can also be used to identify issues with corporate security policies, deterring employees and network guests from violating the rules these policies contain. With so many access points present on a typical business network, it is essential that you have a way to monitor for signs of potential violations, incidents and imminent threats. Today's network threats are becoming more and more sophisticated and able to infiltrate even the most robust security solutions. Intrusion prevention systems work by scanning all network traffic.

Handbook of Information and Communication Security pp Cite as. Intrusion detection is the process of monitoring the events occurring in a computer system or network and analyzing them for signs of possible incidents, which are violations or imminent threats of violation of computer security policies, acceptable use policies, or standard security practices. An intrusion detection system IDS is software that automates the intrusion detection process. An intrusion prevention system IPS is software that has all the capabilities of an IDS and can also attempt to stop possible incidents. Any exceptions are specifically noted. This chapter provides an overview of IDPS technologies.
