Integcheck is a system integrity checker. It checks the integrity of exposed systems by getting a list of MD5 hashes of any important file via SSH, keeps a master list of these on a relatively secure system, and compares this list daily with the current list. As long as the system considered safe is not compromised, it should inform administrators of any changes on the exposed systems.
