+
+In this project, you will develop a tool that verifies the integrity of log files to detect tampering. This project will help you understand file integrity monitoring, hashing techniques, and log analysis.
+
+## Requirements
+
+The tool should:
+
+- Accept a directory of log files as input.
+- Calculate cryptographic hashes (e.g., SHA-256) for each log file.
+- Compare the hashes with previously stored hashes to check for tampering.
+- Report any discrepancies in file integrity
+
+## Example
+
+```bash
+> ./integrity-check -file /var/log/syslog
+> Status: Modified (Hash mismatch)
+
+> ./integrity-check -file /var/log/auth.log
+> Status: Unmodified
+```
