Intrusion Detection System and Snort: A Comprehensive Guide

IDS:
Intrusion detection system is the system which checks for the attack which is being done by
the attackers from inside or outside and we have to detect that attack so that the attackers
didn’t harm us very much as there are various software’s available for intrusion detection in
the machine like Techmint and snort and mostly the usable one is Wireshark
If any break is detected in the system the work of IDS is to log the activity, send an alert to a
console and send knowledge to firewalls or routers. The most common action is to log the
event--doing so provides forensic data for analyzing successful exploits and updating
firewall, router and server policies to prevent recurrences. In several cases, the IDS handle
only the logs and alerts, although the firewalls, routers and servers handle intrusion
prevention.
Introducing Snort
Snort is the software which is used for the intrusion detection system and which can help in
analyzing the network and detects various methodologies for preventing the intrusion and
helping the people to avoid intrusion and perform various tasks which are useful for the
system. Snort gives us various features like below:
 Traffic analysis
 TCP fundamentals
 Linux Fundamentals

 Attack analysis
Snort as a packet tracer
Install the snort software first then detect all the functionality as follows:
