Unauthorized software modifications can compromise security, functionality, and compliance. To prevent tampering, organizations should implement robust measures such as:

1. Code Signing: Digitally sign software to verify authenticity and detect alterations.

2. Access Control: Restrict permissions to critical files and systems, ensuring only authorized personnel can make changes.

3. Integrity Checks: Use checksums or hash functions to monitor files for unexpected modifications.

4. Secure Development Practices: Follow secure coding standards to minimize vulnerabilities.

5. Monitoring & Logging: Deploy real-time monitoring tools to track changes and flag suspicious activity.

By combining these strategies, businesses can safeguard their software against unauthorized alterations and maintain system integrity.
