Normal activity: User logged in
Intrusion detected: DROP TABLE users
Normal activity: User viewed dashboard
Intrusion detected: SELECT * FROM credit_cards

Code Explanation:

The code snippet above is a Java-based Intrusion Detection System (IDS) for identifying possible malicious activities in network traffic, particularly designed to flag SQL injection attempts.

The main class, IntrusionDetectionSystem, initializes a ServerSocket that listens for incoming connections on a specific port number provided as a command-line argument. Upon starting the server, it enters a loop where it waits to accept client connections. Each accepted connection is handed off to a ClientHandler thread which is responsible for reading data sent by the client and analyzing it for potential threats.

The ClientHandler class’ run method reads lines from the client input. It uses a regular expression pattern to match typical SQL keywords that are used in SQL injection attacks (DROP, DELETE, UNION, SELECT, INSERT), ignoring case sensitivity. If any incoming data matches the pattern, an intrusion is detected and logged to the console; otherwise, it is considered normal activity.

The robust threading model allows the IDS to handle multiple clients simultaneously, while pattern matching allows for simple yet effective detection of a common cyber-attack vector. Keep in mind, this is a simplified version of an IDS and in a real-world scenario, much more sophisticated methods are required for accurate and comprehensive threat detection.
