stealthy File Integrity Checker

 The STEALTH program performs File Integrity Checks on (remote) clients. It
 differs from other File Integrity Checkers by not requiring baseline
 integrity data to be kept on either write-only media or in the client's file
 system. In fact, clients will hardly contain any indication suggesting that
 they are being monitored, thus improving the stealthiness of the integrity
 STEALTH uses standard available software to perform file integrity checks
 (like find(1) and sha1sum(1)). Using individualized policy files, it is
 highly adaptable to the specific characteristics of its clients.
 In production environments STEALTH should be run from an isolated computer
 (called the `STEALTH monitor'). In optimal configurations the STEALTH
 monitor should be a computer not accepting incoming connections. The account
 used to connect to its clients does not have to be `root'; usually
 read-access to the client's file system is enough to perform a full integrity
 check. Instead of using `root' a more restrictive administrative or
 ordinary account might offer all necessary requirements for the desired
 integrity check.
 STEALTH itself must communicate with the computers it should monitor. It is
 essential that this communication is secure. STEALTH configurations
 therefore normally specify SSH as the command-shell to use for connecting to
 clients. STEALTH may be configured so as to use but one SSH connection per
 client, even if integrity scans are to be performed repeatedly. Apart from
 this, the STEALTH monitor is commonly allowed to send e-mail to remote
 client systems' maintainers.
 STEALTH-runs itself may start randomly within specified intervals. The
 resulting unpredicability of STEALTH-runs further increases STEALTH's
 STEALTH's acronym is expanded to `Ssh-based Trust Enforcement Acquired
 through a Locally Trusted Host': the client's trust is enforced, the locally
 trusted host is the STEALTH monitor.
