Network Intrusion Detection Systems (SNORT) : IDS/IPS

What is SNORT ?
SNORT is a network based intrusion detection system which is written in C programming language. It was developed in 1998 by Martin Roesch. Now it is developed by Cisco. It is free open-source software. It can also be used as a packet sniffer to monitor the system in real time. The network admin can use it to watch all the incoming packets and find the ones which are dangerous to the system. It is based on library packet capture tool. The rules are fairly easy to create and implement and it can be deployed in any kind of operating system and any kind of network environment. The main reason of the popularity of this IDS over others is that it is a free-to-use software and also open source because of which any user can be able to use it as the way he wants. 

This video will provide you with an introduction to the Snort IDS/IPS by explaining how Snort works and outlines the structure of a Snort rule. An IDS is a system/host planted within a network to capture traffic and identify malicious activity based on predefined rules, after which, this malicious activity is logged, and a notification is sent to the relevant parties informing them of an intrusion

Hello Everyone,
In this Video we will talk about Network Intrusion Detection using Machine Learning.
Detecting network intrusion using various machine learning algorithms. Monitor a network or system for malicious activity and protects a computer network from unauthorized access from users, including perhaps insider. The intrusion detector learning task is to build a predictive model (i.e. a classifier) capable of distinguishing between ‘bad connections’ (intrusion/attacks) and a ‘good (normal) connections’.
