Open Source C++ Change Detection Tools

Open Source Tripwire® is a security and data integrity tool for monitoring and alerting on file & directory changes. This project is based on code originally contributed by Tripwire, Inc. in 2000. A Tripwire check compares the current filesystem state against a known baseline state, and alerts on any changes it detects. The baseline and check behavior are controlled by a policy file, which specifies which files or directories to monitor, and which attributes to monitor them, such as hashes, file permissions, and ownership. When an expected change occurs, such as upgrading a package, the baseline database can be updated to the new known-good state. The policy can also be updated, for example, to reduce noise or cover a newly installed package.
