Malicious Traffic
Theory
Intrusion Detection System (IDS)
A framework designed to monitor network traffic for suspicious activity and known threats, alerting system administrators to potential security breaches.
Working of Intrusion Detection System(IDS)
An IDS (Intrusion Detection System) monitors the traffic on a computer network to detect any suspicious activity.
It analyzes the data flowing through the network to look for patterns and signs of abnormal behavior.
The IDS compares the network activity to a set of predefined rules and patterns to identify any activity that might indicate an attack or intrusion.
If the IDS detects something that matches one of these rules or patterns, it sends an alert to the system administrator.
The system administrator can then investigate the alert and take action to prevent any damage or further intrusion.
Pattern Recognition in Network Security: Understanding the typical patterns of benign traffic (e.g., HTTP requests, DNS queries) versus patterns associated with malicious activities (e.g., repeated failed login attempts).
Introduction to Snort
Snort operates as a NIDS, analyzing network traffic in real-time to identify suspicious activities and potential threats.
Snort uses a signature-based detection approach where it matches network traffic against a set of predefined rules or signatures.
Snort's detection capabilities are driven by a set of rules that specify what network traffic should be considered suspicious.
When Snort detects traffic that matches a rule, it generates alerts and logs details about the potential security incident.
