Intrusion Detection Data: Collection and Analysis
نویسنده
چکیده
Identifying intrusions, misuses, and attacks in general, require that systems be monitored for anomalous behavior. This includes the online analysis of system log files, system activity statistics, and user connection activity. Many intrusion detection and firewall tools will add to the volume of information that must be analyzed. The first step in any such tool is the collection and correlation of the relevant information and events from the system. This aspect of the activity has not been described and is performed to different extents by any particular tool. We describe the relevant information that can be found on most UNIX based systems and how to collect this information using Bourne scripts. We also describe why the collected information is relevant to the analysis task at hand and how this data can be correlated and analyzed.

Intrusion detection is one of the main challenges in wireless systems especially in Internet of things (IOT) based networks. There are various attack types such as probe, denial of service, remote to local and user to root. In addition to known attacks and malicious behaviors, there are various unknown attacks that some of them have similar behavior with respect to each other or mimic the norma...
متن کاملMoving Towards an Adaptive Enterprise Intrusion Detection and Prevention System
In this paper, we describe our plans to create a smarter network defense system through the collection and analysis of network signatures generated by real security threats. To meet this goal, we plan to create software agents interconnected to a central behavior analysis database service where each software agent records attack meta-information collected during previous intrusion attempts. The...
متن کاملData collection mechanisms for intrusion detection systems
Drawing from the experience obtained during the development and testing of a distributed intrusion detection system, we reflect on the data collection needs of intrusion detection systems, and on the limitations that are faced when using the data collection mechanisms built into most operating systems. We claim that it is best for an intrusion detection system to be able to collect its data by ...
متن کاملA Review on Information Flow in Intrusion Detection System
An Intrusion Detection System (abbreviated as IDS) is a defense system, which detects hostile activities in a network. The key is then to detect and possibly prevent activities that may compromise system security, or a hacking attempt in progress including reconnaissance/data collection phases that involve for example, port scans. One key feature of intrusion detection systems is their ability ...
