Introduction to Network Security - Intrusion Detection This paper first discusses the two different types of IDSs, network based and host based. It then covers the two methods used to detect intrusions, signature based and behavior based. This is a basic paper that will only touch on a broad overview of IDS technologies; it is only intended for the security engineer needing a high level overview of intrusion detection

Intrusion Detection: Filling in the Gaps If you've recently purchased a new intrusion detection system, you're probably just beginning to realize how painful it is to take analysis beyond a window full of warning messages to meaningful information. And no matter how much marketing is done by companies to convince you otherwise, today's commercial products still have quite a way to go. After all, detecting events is only half the job; you still need to manage your systems, identify sources, and investigate the extent of attacks.

Selecting an Intrusion Detection System Selecting an intrusion detection system (IDS) to protect your network is a decision that should not be made lightly, quickly, or without a firm understanding of the technology, options, or the potential impacts. The decision process can be divided into the following steps: Identify the need, Gain a general understanding of intrusion detection systems, Gain a detailed understanding of the network, Evaluate various IDS systems, and Determine policy and procedures.

Understanding Intrusion Detection Systems The paper is designed to outline the necessity of the implementation of Intrusion Detection systems in the enterprise environment. The purpose of the paper is to clarify the steps that needs to be taken in order to efficiently implement your Intrusion Detection System, and to describe the necessary components. The work should also clarify what you can expect of your Intrusion Detection System, and what you have to anticipate for, prior to deployment. Lets get started!

How to Choose Intrusion Detection Solution In order to understand IDS properly, one must first have an understanding of intrusions. Intrusion is difficult to define because not everyone agrees on what is consider of an intrusion. Intrusions are defined as attempts to compromise confidentiality, integrity, or availability of data, or to bypass the security mechanisms of an IT system. An intrusion may be generally described as a sequence of related actions by a malicious adversary that results in the occurrence of unauthorized breaches to a target system or network.

The History and Evolution of Intrusion Detection The aim of this paper is to examine the origins of detecting, analysing and reporting of malicious activity, where it is today and where it appears to be heading in the future. Some of the many techniques and tools presently used in Network defense will be explored as well.

IDS - Today and Tomorrow This paper is not intended to predict the future, but bring to light emerging technologies and trends in the field of IDS that could make the life of the security specialist easier (if there is such a thing).

An Introduction to Intrusion Detection Systems In a nutshell, intrusion detection systems do exactly as the name suggests: they detect possible intrusions. More specifically, IDS tools aim to detect computer attacks and/or computer misuse, and to alert the proper individuals upon detection. An IDS installed on a network provides much the same purpose as a burglar alarm system installed in a house. Through various methods, both detect when an intruder/attacker/burglar is present, and both subsequently issue some type of warning or alert.

An Introduction To Distributed Intrusion Detection Systems A distributed IDS (dIDS) consists of multiple Intrusion Detection Systems (IDS) over a large network, all of which communicate with each other, or with a central server that facilitates advanced network monitoring, incident analysis, and instant attack data. By having these co-operative agents distributed across a network, incident analysts, network operations, and security personnel are able to get a broader view of what is occurring on their network as a whole.
