INTRUSION DETECTION SYSTEM CONCEPTS

I. TỔNG QUAN HỆ THỐNG IDS
1. Khái niệm về hệ thống phát hiện xâm nhập IDS
Hệ thống phát hiện xâm nhập – IDS (Intrusion Detection System) là một hệ
thống có nhiệm vụ giám sát các luồng dữ liệu (lưu lượng) đang lưu thông trên mạng, có khả năng phát hiện những hành động khả nghi, những xâm nhập trái ph[r]

Giới thiệu
Mục đích của các biện pháp phát hiện xâm nhập máy tính là phát hiện ra các loại xâm phạm an toàn cơ bản như:
+ Xâm phạm tính toàn vẹn.
+ Từ chối dịch vụ.
+ Truy nhập trái phép.
Khó khăn: nảy sinh một số vấn đề làm hạn chế hiệu quả của các biện pháp phát hiện xâm nhập này, như:
+ Người[r]

Ngày nay rất nhiều doanh nghiệp, tổ chức sử dụng ứng dụng web để cung cấp dịch vụ thương mại trực tuyến, kết nối khách hàng, đối tác và nhân viên một cách hiệu quả nhất. Tuy nhiên, ứng dụng web cũng đem đến những rủi ro đáng kể cho hệ thống và dữ liệu. Đa số ứng dụng web có thể bị những lỗi mà các p[r]

This paper discusses concepts for three-component fuel bundles containing plutonium, uranium and thorium for use in pressurised heavy water reactors, and cases for and against implementation of such a nuclear energy system in the United Kingdom.

In this paper, we present a synchronization algorithm for Multi-Carrier CDMA (MC-CDMA) systems using a time-multiplexed synchronization channel. The simulations results show that a system using proposed algorithm has much higher timing detection probability than using other algorithms, especially in[r]

Autonomous Agents For Intrusion Detection. 2 AAFID was the first architecture of using autonomous agents for intrusion detection The system is based on independent entities called autonomous agents. .. order to limit the possibilities of interaction between the agents themselves and a potential[r]

Chapter 8 Process modeling. In this chapter you will learn how to draw data flow diagrams, a popular process model that documents a system’s processes and their data flows. You will know process modeling as a systems analysis tool when you can Define systems modeling and differentiate between logic[r]

In this study, we present an integrated navigation system for the autonomous mobile robot in the dynamic environment by incorporating the techniques proposed in our previous studies, including object detection and tracking system, localization system and motion planning system, into a completed navi[r]
