IDP intrusion detection and prevention (Intrusion Detection and Prevention)
Intrusion Detection and Prevention IDP provides the dual function, available for immediate suspension of intrusions, including automatically block attack packets discarded, is an active protective type of security products.
Early Intrusion Detection System (IDS; Intrusion Detection System) make more use of network traffic anomalies to determine whether the suspected attacks occurred, usually only issued a warning without a denial-of-attack spread function; and IDP are relatively new field of Internet security protection technology through continuous evolution can be used now than in the invasion of modalities, immediate suspension of attacks on intrusion development.
IDP is currently positioned as the industry makes more intelligent security products, while others of such products as Intrusion Prevention Systems (IPS; (Intrusion Prevention System) Many information security market supplier of integrated firewall, intrusion systems and enterprise virtual network (VPN) features such as the introduction of integrated intrusion detection and prevention function of security products. For example, in the traditional firewall products, the installation of condition monitoring technology and surveillance against denial-of-attack (DoS) features, so that a malicious denial-of IDP with the original firewall packet data capabilities, at the same time be able to monitor other possible intrusions.
It is worth mentioning that, IDP usually have the auto-learning and capacity to respond may be in the database, establish a new model for the invasion, when there are attacks, IDP will be able to take the initiative to cope with, in order to provide accuracy, thereby reducing false positives miscarriage of justice opportunities.
IDS Intrusion Detection System (Intrusion Detection System)
IDS is usually an important node in the network set up with the host system above can monitor network traffic and content, or an analysis of the host mobility within a file. When they find suspicious activity, IDS will be issued a warning in accordance with user settings in order to block possible attacks.
IDS can be divided into network-based (Network-based), host (Host-based) two kinds of products, some also integrate vulnerability management and trapping system (Honeypot) technologies. Detection methods, including the main characteristics of the detection ratio (Signature Based Detection), abnormal behavior detection (Behavioral Anomaly Detection), protocol anomaly detection (Protocol Anomaly Detection).
Basically, the installation of dry to important nodes in the network over the network-based intrusion detection system which can check the network connection status and transfer the contents of the packet, at the same time analysis and processing. When they find online, or aggressive behavior is in line with user-defined "dangerous", they will immediately issue a warning notice in the shortest time administrator for defense; as host intrusion detection systems are deployed in the host system on, to monitor the system files, programs, or in the log file if there is unusual activity.
As the IDS is a passive type of defensive action, can only detect events that have taken place, but can not be effective to prevent hackers or viruses; Similarly, IDS can not take the initiative to launch counter attacks will only monitor screen displays a warning screen or send e-mail or SMS to inform administrators of other systems to reduce the network the possibility of harm.
IDS products can be said at present the market is an open debate, most security vendors are offering similar functionality.
