You are the chief technology officer of a security start-up company who wants to find exceptions in the history of network connection between computers: unusual network traffic will help you find staff for downloading all your CRM history As they seemed to be about to end or transfer, so unusually large amounts of money in a new bank account. If you are interested in this sort of thing, you will like unsupervised, anomaly detection algorithms of this survey. Your brain, the members of the Google team, want to know if you have a YouTube video. This is the truth story of the research "YouTube's Cat Detector" that ignited the public's enthusiasm for artificial intelligence. In this article, Stanford University and researchers of Andrew · Ukkkl and Google brain team, categories including cats, YouTube videos are described in several categorized algorithms

Abnormality-based detection is an important area of ​​research botnet detection field. The basic idea comes from some irregular network traffic analysis, such as improving the behavior of the system, which shows traffic anomalies, high network latency, traffic and malicious network activity, depending on the port. It is further based on host and network based method anomalies. In the host-based way, the monitoring behavior of individual machines is suspicious. Although host-based monitoring is very important as all machines are required to have effective monitoring tools, this method does not have extensibility

Anomaly detection can find unexpected or unusual patterns of base activity. This category can be achieved by host and network-based intrusion detection systems. For HIDS, an exception can repeat a failed login attempt, or abnormal activity on the device port indicates a port scan. In case of NIDS, using a method of abnormal behavior, you need to establish a baseline to create a standard case so that continuous flow modes can be compared. When current real-time traffic outside this range throws an exception warning, a series of traffic patterns is considered to be acceptable

Intrusion detection system (IDS) is a system that monitors network traffic about suspicious activity and alerts you when such activity is discovered. Abnormality detection and reporting is a major function, but intrusion detection systems can deal with such things as blocking traffic sent from suspicious IP addresses when incorrect activity or abnormal traffic is detected. While the intrusion detection system monitors the network for potential malicious activity, false positives (false positives) are also prone to occur. As a result, organizations need to fine-tune the IDS product when they first install. This means that the intrusion detection system is correctly configured to identify normal traffic on the network compared to potentially malicious activity.
