A Python-based log analysis tool that detects suspicious login activity by parsing system logs and identifying repeated failed login attempts from IP addresses.

This project simulates how security analysts monitor logs to detect potential brute-force attacks or unauthorized access attempts.

It reads log files, extracts important data, and generates a security report.

✔ Extracts IP addresses from logs
✔ Detects failed login attempts
✔ Counts failures per IP
✔ Generates a summary report
✔ Uses regex for pattern detection

• Python File Handling
• Regular Expressions (re)
• Dictionaries & Loops
• Modular Programming
• Basic Security Log Analysis
