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 servers where centralized control and reporting is not needed and professional support is not a requirement.
Open Source Tripwire retains the original core functionality of data integrity for servers. Utilizing a basic command line interface, the software will detect changes on each server on which it is installed, alerting users to intrusions and unexpected changes. With the available source code, Open Source Tripwire can be compiled onto a broad range of UNIX- and Linux-based systems, with the potential for modification to meet unique, local requirements. And, or course, it has the benefit of no initial investment.
The latest Open Source Tripwire, version 2.4.0, retains the same intrusion detection features as the original 2.3 release, with improved scripting functionality for compiling onto a wider range of POSIX (Linux/BSD/UNIX-like) operating systems. It is available for download from SourceForge.net. For individual server deployments and smaller installations, many find Open Source Tripwire a solid choice for intrusion detection and security.
