What is the biggest issue or problem with an IDS?

One significant issue with an IDS is that they regularly alert you to false positives. In many cases false positives are more frequent than actual threats. An IDS can be tuned to reduce the number of false positives, however your engineers will still have to spend time responding to them.

What is intrusion detection system what are its application?

An intrusion detection system (IDS) is a device or software application that monitors a network for malicious activity or policy violations. Any malicious activity or violation is typically reported or collected centrally using a security information and event management system.

What are the sensors used in home intrusion detection system?

Interior intrusion sensors can be active or passive, covert or visible, or volumetric or line detectors. The application classes of interior sensors discussed include boundary penetration sensors, interior motion sensors, and proximity sensors.

What are the characteristics of anomaly based IDS?

In contrast to signature-based IDS, anomaly-based IDS in malware detection does not require signatures to detect intrusion. In addition, an anomaly-based IDS can identify unknown attacks depending on the similar behavior of other intrusions.

What are the two main methods used for intrusion detection?

Intrusion detection systems primarily use two key intrusion detection methods: signature-based intrusion detection and anomaly-based intrusion detection. Signature-based intrusion detection is designed to detect possible threats by comparing given network traffic and log data to existing attack patterns.

Which sensor detect intruders breaking into a building?

Passive infrared sensors
Motion sensors. Passive infrared sensors detect the body heat of an intruder and generate an alarm in response. Ideally, an area will be protected by dual-technology sensors.

Which is uses a magnetic field to detect intrusions?

Which Intrusion Detection System (IDS) uses a magnetic field to detect intrusions? Also called an electrostatic IDS as it creates a balanced electrostatic field between itself and the object being monitored. If an intruder comes within a certain range, it causes capacitance change.

What is Intrusion Detection System What are the difficulties in anomaly detection?

An anomaly-based intrusion detection system, is an intrusion detection system for detecting both network and computer intrusions and misuse by monitoring system activity and classifying it as either normal or anomalous. This is known as strict anomaly detection.

What metrics are useful for profile-based intrusion detection?

Examples of metrics that are useful for profile-based intrusion detection are the following: Counter: A nonnegative integer that may be incremented but not decre- mented until it is reset by management action. Typically, a count of certain event types is kept over a particular period of time.

What are the disadvantages of intrusion detection?

An only disadvantage of the Intrusion Detection System is they cannot detect the source of the attack and in any case of attack, they just lock the whole network.
