Using the browser, an administrator specifies transactions to run, intervals, alarm settings, etc.
Saswire is a Perl program which generates a database in SDBM format containing the modification time, MD5 checksum, size, and creation time for a list of files specified in a input file. It is designed to check for unwanted modifications of Unix system binaries if security is compromised.
