SOFFIC is a Linux kernel patch that provides file
integrity control integrated into the normal
system operation (on-the-fly). It checks a file's
integrity each time a monitored file is opened for
reading or execution, and issues a warning if it
is found to be invalid. It protects against
rootkits, backdoors, worms, viruses, Web
defacement, unauthorized installation and use of
new software (e.g. malicious tools), etc.
