#Open Source Tripwire®
Open Source Tripwire® software is a security and data integrity tool useful for monitoring and alerting on specific file change(s) on a range of systems. The project is based on code originally contributed by Tripwire, Inc. in 2000.
Open Source Tripwire is suitable for monitoring a small number of Linux servers, where centralized control and reporting is not needed and professional support or system automation is not a requirement.
