Vulnerability exploits usually come in the form of malicious inputs to a target application or service that attackers use to interrupt and gain control of an application or machine. The IPS often sits directly behind the firewall and provides a complementary layer of analysis that negatively selects for dangerous content. Specifically, these actions include:. As an inline security component, the IPS must work efficiently to avoid degrading network performance. It must also work fast because exploits can happen in near real-time. The IPS must also detect and respond accurately, so as to eliminate threats and false positives legitimate packets misread as threats. The IPS has a number of detection methods for finding exploits, but signature-based detection and statistical anomaly-based detection are the two dominant mechanisms.

Intrusion detection

The intrusion detection and prevention system IDS notifies you of attempts to hack into, disrupt, or deny service to the system. IDS also monitors for potential extrusions, where your system might be used as the source of the attack. These potential intrusions and extrusions are logged as intrusion monitor audit records in the security audit journal and displayed as intrusion events in the Intrusion Detection System graphical user interface GUI. You can configure IDS to prevent intrusions and extrusions from occurring. Intrusions encompass many undesirable activities, such as information theft and denial of service attacks. The objective of an intrusion might be to acquire information that a person is not authorized to have information theft. The objective might be to cause a business harm by rendering a network, system, or application unusable denial of service , or it might be to gain unauthorized use of a system as a means for further intrusions elsewhere.

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.
