SOFFIC is a Linux kernel patch for kernel 2.4.18 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, and much more.
