The main technology of intrusion monitoring is

1. Intrusion detection technology The technique mainly includes: C. Abuse detection technology, abnormal detection technology, advanced detection technology, intrusion deception technology, and intrusion response technology.

2. The technology adopted by the intrusion detection system can be divided into two types: feature detection and abnormal detection.Feature detection Signature-based detection, also known as Misusedetection, assumes that the intruder's activity can be represented by a pattern, and the goal of the system is to detect whether the subject activity conforms to these patterns.

3. ● Abnormal detection technology: collect and analyze the normal behavior learned in the past, and establish a normal behavior model. Extract the current behavioral characteristics and match them with the normal behavior model. If the matching is successful, it will be regarded as a legitimate behavior, otherwise it will be judged as an intrusion.

Intrusion detection system detector acquisition method

1. The methods of intrusion detection system detector acquisition of network traffic include: data acquisition, depth packet detection, etc. Data acquisition Data acquisition is one of the important methods for intrusion detection system detectors to obtain network traffic. For this method, the intrusion detection system needs to rely on intercepting network traffic and analyzing its content to identify potential malicious network activities.

2. Intrusion detection system detector acquisition networkThere are three ways to use the mirroring function of the switching device, connecting a hub in series in the network link, and connecting a splitter in the network link in series. So choose option B.

3. The method of intrusion detection system to obtain network traffic: connect a hub in series in the network link. Intrusion detection refers to "the detection of intrusion or attempt to break into the system by operating on behavior, security log or audit data or other information available on the network".

ids is the abbreviation of what device

1. Intrusion-detection system (abbreviated as IDS) is a kind of network security device Or shouldUsing software, you can monitor network transmission or system to check for suspicious activities or violations of enterprise policies. Issue an alarm or take proactive response measures when it is detected.

2. IDS is the abbreviation of "Intrusion Detection Systems" in English, which means "intrusion Detection Systems" in Chinese. IDS is the abbreviation of "Intrusion Detection Systems" in English. It means "intrusion detection system" in Chinese.

3. Intrusion detection system (IDS) is a kind of security for real-time monitoring of network transmission. Unlike traditional network security equipment, when an alien intruder is detected, it will immediately call the police and take positive countermeasures.
